The purpose of this study was to investigate the safety and efficacy of Rest-ZZZ, a natural sleep supplement, in healthy adults without a diagnosed sleep disorder. This randomized, double-blind, placebo-controlled, cross-over study consisted of three 7-day supplementation periods with either Rest-ZZZ, Diphenhydramine (DPH), or Placebo, with a 7-day washout. Twenty-seven participants were randomized to one of three intervention sequences and the Healthy People Sleep Quality Index (HPSQI), Quality of Life (QoL), and Profile of Mood States (POMS) questionnaires were assessed at the beginning and end of each supplementation period. Rest-ZZZ and Placebo showed improvements in sleep-related QoL (p ≤ 0.044) and total mood disturbance (TMD) (p = ≤ 0.028). Fatigue–Inertia was reduced by all study products (p ≤ 0.031). DPH did not result in any significant improvements on sleep quality parameters. A subgroup analysis of participants ≤ 45 years found enhanced efficacy of Rest-ZZZ and improvement in sleep-related QoL vs. Placebo (p = 0.007), as well as improvements in sleep duration (p = 0.007), sleep debt (p = 0.011), and sleep-related QoL (p = 0.033). DPH supplementation resulted in significant improvement in only sleep debt (p = 0.038). Rest-ZZZ had a safe hematology and chemistry profile. Rest-ZZZ resulted in restful sleep that generated corresponding improvements in sleep-related QoL and overall mood. Rest-ZZZ is an efficacious sleep supplement with a favorable safety profile, particularly in those aged 25–45 years.

Current methods to detect recent delta-9-tetrahydrocannabinol (THC) use cannot objectively quantify its psychoactive effects (PE). The Cognalyzer®, an electroencephalography (EEG)-based method, detects and quantifies the strength of THC-induced PE on a scale from 0 to 100%. This study assesses the relationship between the magnitude of Cognalyzer® PE predictions and reported subjective drug effects for 4-h post-cannabis inhalation. Seventy-five participants were enrolled in the study. Prior to ad libitum cannabis inhalation, an EEG recording episode was completed. Immediately after inhalation, the Drug Effects Questionnaire (DEQ) was administered and another EEG recording performed. For 25 participants, the study ended. For 50 participants, assessments were repeated at 30-min intervals for 4 h. EEG files were blinded and analyzed using two versions of the Cognalyzer® algorithm. The relationship between the Cognalyzer® PE level results and the DEQ was assessed using generalized linear models and multiple regression. There were significant PE increases from pre-cannabis for up to 3.5 h. Mean reports of feeling drug effects were > 0 at all post-inhalation time points (p ≤ 0.024). Furthermore, there were significant relationships between the Cognalyzer® PE and self-reported perception of drug effects (p ≤ 0.001). Subgroup analysis showed that Cognalyzer® PE levels were impacted by cannabis use history, subjective ratings of drug effects, oral fluid THC concentration and the cannabis product inhaled. The findings show that the Cognalyzer® can be used to objectively determine the strength of cannabis psychoactive effects that cannabis products create on consumers and how it changes depending on their experience with cannabis. The Cognalyzer® can be used to conduct scientific consumer research to generate trustworthy informational material about the psychoactive experience of cannabis products. For clinical research, the Cognalyzer® can be used to study the pharmacodynamics of cannabinoids or delivery systems, such as nano-emulsifications.

Stress is a complex life occurrence essential for survival and goal achievement but can be damaging in excess. Because of the high prevalence of stress in North America, a safe supplement that effectively reduces stress is in demand. The objective of this study was to investigate the efficacy and safety of AlphaWave® l-Theanine on whole-scalp and frontal alpha power, midline theta power, and salivary cortisol in healthy, moderately stressed adults. This was a randomized, triple-blind, placebo-controlled, crossover study that consisted of two study periods with a 7-day washout. A single dose of AlphaWave® l-Theanine (200 mg) or placebo was administered. To induce stress, a mental arithmetic test (MAT) was administered before and after the dose. Electroencephalogram, salivary cortisol, blood pressure, heart rate, self-reported stress, adverse events, clinical chemistry, and hematology were assessed to evaluate efficacy and safety. Increases in heart rate, blood pressure, and self-reported stress and state anxiety indicated that participants experienced stress during the MAT. AlphaWave® l-Theanine led to a greater increase in frontal region and whole-scalp alpha power 3 h post-dose compared to placebo (p ≤ 0.050). Within groups, there were increases in alpha power, at 3 h with AlphaWave® l-Theanine, over the whole recording and during the eyes-open portions (p ≤ 0.048) of the alpha task. The changes in alpha wave activity are supported by greater decreases in salivary cortisol 1 h post-dose (p

The study aimed to examine the role of anA randomized, triple-blind, placebo-controlled, parallel study consisted of a 56-day intervention period with a 28-day pre-vaccination period, an influenza vaccination on Day 28 and 28-day post-vaccination period. Fifty healthy adults 40-80 years of age who had not received their flu vaccine were randomized to either UP446 or Placebo. At baseline, Days 28 and 56, immune and oxidative stress markers were measured in blood and a quality of life questionnaire was administered. Participants completed the Wisconsin Upper Respiratory Symptom Survey (WURSS)-24 daily.In the post-vaccination period, total IgA and IgG levels increased in participants supplemented with UP446 vs. those on Placebo (These results suggest a 56-day supplementation with UP446 was beneficial in mounting a robust humoral response following vaccination. Increasing GSH-Px in the pre-vaccination period may help improve antioxidant functions and potentially mitigate the oxidative stress induced following vaccination.

Transdermal cannabinoids may provide better safety and bioavailability profiles compared with other routes of administration. This single-arm, open-label study investigated a novel topical transdermal delivery system on the pharmacokinetics of cannabidiol (CBD) and tetrahydrocannabinol (THC).Participants were 39.5 ± 7.37 years old and healthy, based on a review by the Medical Director. Blood was collected pre-dose and 10, 20, 30, and 45 min, and 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, and 12 h after topical application of 100 mg CBD:100 mg THC. Psychoactive effects were assessed prior to each timepoint. Area-under-the-curve (AUCAUCTo our knowledge, this is the first pharmacokinetic study in humans that demonstrated CBD and THC entering systemic circulation via transdermal administration . This study represents an important contribution to understanding the pharmacokinetics of transdermal cannabinoids.ClinicalTrials.gov Identifier-NCT05121506 (November 16, 2021).

Introduction Current standards for identifying recent cannabis use are based on body fluid testing. The Cognalyzer® is a novel electroencephalography (EEG) measurement device and algorithm designed to objectively characterize brainwave alterations associated with cannabis. The objective of this study was to assess the accuracy, sensitivity and specificity levels of the Cognalyzer® to characterize brainwave alterations following cannabis inhalation. Methods Seventy-five participants, aged 19–55 years, were enrolled, and oral fluid samples were collected pre-cannabis inhalation. EEG and subjective drug effects questionnaire (DEQ) were administered pre- and post-ad libitum cannabis inhalation. Fifty participants remained in the clinic for 4 h post-inhalation. Blinded analyses of the EEG files were conducted by Zentrela Inc. using two versions (V1 and V2) of the Cognalyzer® algorithm. Pre- vs. post-inhalation comparison status was characterized by the Cognalyzer® and summarized for: sensitivity, specificity, accuracy, percent false positive, percent false negative and positive and negative predictive value. The null hypothesis was tested using McNemar’s test. Cognalyzer® results pre- and post-inhalation were combined with the oral fluid tetrahydrocannabinol (THC) concentration to evaluate potential to improve current drug testing. Results The two versions of the Cognalyzer® algorithm had similar diagnostic results. Diagnostic outcomes were improved when participants with missing EEG recordings or electrode placement errors were removed. The Cognalyzer® accuracy was 85.5% and 83.9%, sensitivity was 87.1% and 88.7%, and specificity was 83.9% and 79.0% for algorithm V1 and V2, respectively. Combining Cognalyzer® results with oral fluid concentrations reduced false-positive oral fluid test results by up to 49%. Conclusion The Cognalyzer® characterized brainwave alterations associated with cannabis inhalation with high levels of accuracy in a population of participants with varied cannabis inhalation histories, relative to the comparison standard of pre- vs. post-inhalation status. The Cognalyzer® allows the results to be generalized to the larger population addressing a limitation in currently accepted standards.

Introduction: The concept of a lack of intervention in a pre-disease population with hypercholesterolemia has not been previously reported. This study examined the concept of the effects of the absence of an intervention in the placebo group vs. supplementation of a special formulation of Panax Notoginseng (FNG) in relation to cardiovascular disease (CVD) risk markers and validated CVD-risk factor scores. Methods: Participants in this randomized, placebo-controlled, triple-blind study were supplemented with FNG or placebo for 12 weeks. Lipid profile, blood pressure (BP), and endothelial vasodilation parameters were assessed at baseline and weeks 4, 8 and 12 and safety assessed at screening and end of study. The participants in both groups followed the Therapeutic Lifestyle Change (TLC) diet during a 4-week run-in and throughout the study. The TLC diet for 4 weeks ensured all participants starting the study had similar baseline measurements and placebo effects were adequately addressed. Results: Participants in the placebo group had a non-significant 1.37% reduction in HDL-C at 8 and 12 weeks, as well, as an increase in systolic BP from baseline at week 12. Participants in the placebo had no change in estimated Framingham Heart Study 10-year risk for CVD, while the FNG group had a 0.1% reduction from baseline at week 12. A total of 67.5% of participants supplemented with FNG had improvements in at least two CVD risk factors (LDL-C, HDL-C and systolic BP) compared to 40.0% of those on placebo (p=0.007). In a post-hoc subgroup analysis of participants with baseline LDL-C >3.5 mmol/L, 41.7% of participants in the FNG group had reductions in their systolic BP and LDL-C and improvements in HDL-C levels at week 12, compared to placebo where there were no improvements. Conclusions: The lack of an intervention in a population at risk of CVD, represented by the placebo group, resulted in a negative impact on cardiovascular risk factors and warrants further investigation on the importance of pre-emptive supplementation of notoginseng in populations with mild hypertension and hypercholesterolemia. This study supports a previously defined concept in nutritional interventions which described changing from proof of efficacy to that of probable harm in pre-disease populations.

Too much stress, however, can be damaging. There is a high prevalence of stress in North America, creating a demand for a safe and effective supplement to reduce it. This study investigated the effectiveness and safety of AlphaWave® l-Theanine on brainwaves and salivary cortisol in healthy, moderately stressed adults facing an acute stressor. This was a randomized, triple-blind, placebo-controlled, crossover study that consisted of two study periods with a 7-day washout. A single dose of 200 mg of AlphaWave® l-Theanine or placebo was administered before and after a mental arithmetic test to elicit acute stress. Electroencephalogram, salivary cortisol, blood pressure, heart rate, self-reported stress, and safety were assessed to evaluate efficacy and safety. This study was conducted during the coronavirus pandemic, which has had a rapid and significant effect on both physical and mental health around the world. A single dose of AlphaWave® l-Theanine had significant positive effects on brainwaves, salivary cortisol, and self-reported state anxiety compared to the placebo in response to an acute stress challenge. These changes are indicative of relaxation in the brain and suggest a calming response in a moderately stressed but otherwise healthy population. AlphaWave® l-Theanine was found to be safe and well tolerated by participants.

OBJECTIVES: Bioequivalence of vitamin E and folate in a single oral dose multivitamin (MVI) gummy or tablet. METHODS: This crossover clinical trial involved healthy adults randomized to either gummy or tablet MVI containing vitamin E (VE – 279 IU gummy; 239 IU tablet) and folate (1860 µg gummy; 1877 µg tablet) as a single dose in Phase 1 with blood samples collected at pre-dose and 0.5-, 1-, 2-, 4-, 6-, 8-, 9-, 10-, 24-, and 48-hours after dosing, followed by a 2-week washout period. In Phase 2, participants crossed over to receive MVI in the form not previously given, with blood draws at the same timepoints. Maximum Concentration (Cmax), Time of Maximum Concentration (Tmax), and Area Under the Curve (AUC) were calculated for each subject for both vitamin forms. Bioequivalence for AUC, Tmax, and Cmax was defined as a 90% confidence interval (CI) for the gummy to tablet comparator ratio of the geometric mean between 80% and 125%. RESULTS: Nineteen participants completed the study. Both gummy and tablet demonstrated absorption for both vitamins. The ratio of geometric means demonstrated bioequivalence between gummy and tablet for both VE and folate with both AUC and Cmax. While bioequivalence was also demonstrated for VE with Tmax, folate absorption peaked earlier in the gummy group (Tmax 1.89 hrs) than the tablet group (Tmax 4.00 hrs), shifting Cmax values in the gummy group to earlier timepoints than in the tablet group without affecting total absorption AUC. These results were consistent with a previous pilot study. CONCLUSIONS: Overall, under the conditions of this study, both gummy and tablet showed similar absorption of vitamin E and folate.

In this randomized, double-blind, placebo-controlled, multicentre, parallel, 8-week study, the efficacy of a daily dose of 1200 mg of protein hydrolysate from Coldwater Shrimp (Pandalus borealis) on ambulatory and office blood pressure was investigated in 144 free-living adults with mild to moderate hypertension. The primary outcomes of the study were daytime ambulatory systolic blood pressure and office blood pressure. During the 8-week intervention period and in the intention-to-treat analysis (n=144), there were significant reductions in the group consuming the shrimp-derived protein hydrolysate relative to the placebo group in daytime ambulatory systolic blood pressure at 4 weeks (p=0.014) and at 8 weeks (p=0.002), and in office systolic blood pressure at 2 weeks (p=0.031) and 4 weeks (p=0.010), with a trend toward significance at 8 weeks (p=0.087). By 8 weeks, significant and favourable improvements in the group consuming the shrimp-derived protein hydrolysate relative to the placebo group were also observed for several secondary outcomes, including 24-hour ambulatory systolic and diastolic blood pressure, daytime ambulatory diastolic blood pressure, and daytime and 24-hour ambulatory mean arterial pressure. Also by Week 8, there was a statistically significant difference between groups in the distribution of subjects across National Institutes of Health-defined blood pressure categories (i.e., Normotensive, Prehypertensive, Stage 1 hypertension, and Stage 2 hypertension), with a more favourable distribution in the shrimp-derived protein hydrolysate group than in the placebo group (p=0.006). Based on exploratory analyses conducted only in participants in the shrimp-derived protein hydrolysate group, angiotensin II levels were significantly reduced relative to baseline. This study is registered at ClinicalTrials.govNCT01974570.

OBJECTIVE To investigate the clinical efficacy of a multi-strain probiotic product on bowel habits and microbial profile in participants with functional constipation. METHODS This was a randomized, double-blind, placebo-controlled and parallel-arm study. Altogether 94 otherwise healthy adults aged 18 to 65 years with symptoms of functional constipation were randomized as part of the intention-to-treat population. The participants received a placebo or the probiotic product (1.5 × 1010 CFU/day), consisting of Lactobacillus acidophilus DDS-1, Bifidobacterium animalis subsp. lactis UABla-12, Bifidobacterium longum UABl-14 and Bifidobacterium bifidum UABb-10 over 4 weeks. Outcomes included the patient assessment of constipation-symptom (PAC-SYM) questionnaire, stool frequency and consistency, and microbial profile. RESULTS There were no significant between-group differences in the PAC-SYM score, despite significant within-group differences (P

Background Collagen is the primary component in human skin. With age, there is loss of skin elasticity and collagen, resulting in wrinkle formation and reduction in skin appearance. Aims The objective of this randomized, triple-blind, placebo-controlled study was to evaluate the safety and efficacy of a hydrolyzed marine collagen (Vinh Wellness Collagen, VWC) on aspects of skin health and quality in women between 45 and 60 years of age. Patients/methods Assessments of skin wrinkles, elasticity, and self-reported appearance were conducted using the VISIA skin analysis system, Cutometer® , and Skin Quality Visual Analogue Scale. Outcomes were assessed at weeks 0 (baseline), 6, and 12. Results After 12 weeks, participants supplemented with VWC had a significant 35% reduction in wrinkle score (P = .035) from baseline. Participants in the VWC group showed a 24% greater reduction in wrinkles on the right side of the face than those on placebo. A planned subgroup analysis based on age showed women 45-54 years had a significant 20% and 10% improvement in cheek skin elasticity from baseline to week 6 (P = .016) and 12 (P = .022), respectively. At week 12, participants in the VWC group reported greater percentage improvements in overall skin score (9%) and wrinkle (15%), elasticity (23%), hydration (14%), radiance (22%), and firmness (25%) scores vs placebo. Conclusion Supplementation with VWC was found to be safe and well-tolerated. The results of this study support the use of fish-derived hydrolyzed collagen for the improvement of skin health in an aging population.

The lack of effective treatment for chronic discomfort without negative side effects highlights the need for alternative treatments. Pain Bloc-R is a natural health product composed of vitamins B6, B12, D, white willow bark extract, Angelica root extract, acetyl L-carnitine HCl, caffeine, L-theanine, Benfotiamine, and L-tetrahydropalmatine. The objective of this study was to compare the effects of Pain Bloc-R, acetaminophen, and placebo on unresolved aches and discomfort as assessed by the brief pain inventory (BPI) and modified Cornell musculoskeletal discomfort questionnaires. This randomized, double-blind, placebo-controlled, crossover study consisted of three 7-day periods with Pain Bloc-R, acetaminophen, or placebo, each separated by a 7-day washout. Twenty-seven healthy adults (ages 22&ndash, 63 years) were randomized to receive the three interventions in different sequences. The BPI &ldquo, pain at its worst&rdquo, scores were significantly lower when participants took Pain Bloc-R than when they took acetaminophen (21.8% vs. 9.8% decrease, p = 0.026) after seven days of supplementation. Pain Bloc-R achieved a significant improvement in the &ldquo, pain at its least&rdquo, score, significantly decreased the interference of discomfort in walking, and significantly decreased musculoskeletal discomfort total scores (34%, p = 0.040) after seven days. In a post hoc subgroup analysis based on age and gender, male participants &le, 45 years taking Pain Bloc-R reported significant reductions in pain severity and pain interference vs. acetaminophen. Pain Bloc-R performed as well as acetaminophen in managing unresolved non-pathological pain in otherwise healthy individuals.

Specific probiotic strains can alleviate the gastrointestinal (GI) symptoms and psychiatric comorbidities of irritable bowel syndrome (IBS). In this randomized, double-blind, placebo-controlled study, the efficacy of Lactobacillus paracasei HA-196 (L. paracasei) and Bifidobacterium longum R0175 (B. longum) in reducing the GI and psychological symptoms of IBS was evaluated in 251 adults with either constipation (IBS-C), diarrhea (IBS-D), or mixed-pattern (IBS-M). Following a 2-week run-in period, participants were randomized to one of three interventions: L. paracasei (n = 84), B. longum (n = 83) or placebo (n = 81). IBS symptoms, stool frequency and consistency and quality of life were assessed by questionnaires. The differences from baseline in the severity of IBS symptoms at 4 and 8 weeks were similar between groups. Participants in this study were classified, after randomization, into subtypes according to Rome III. Within the L. paracasei group, complete spontaneous and spontaneous bowel movement frequency increased in participants with IBS-C (n = 10) after 8 weeks of supplementation (both p < 0.05) and decreased in participants with IBS-D (n = 10, p = 0.013). Both L. paracasei and B. longum supplementation improved the quality of life in emotional well-being and social functioning compared with baseline (all p < 0.05). In conclusion, L. paracasei and B. longum may reduce GI symptom severity and improve the psychological well-being of individuals with certain IBS subtypes.

A-F Betafood&reg, is a whole food-based health product. The product contains phytonutrients and bioactives with antioxidant properties that may support gallbladder and liver function. Herein, we investigated the efficacy of A-F Betafood&reg, on gallbladder and liver function. In this randomized, placebo-controlled, parallel study fifty overweight but otherwise healthy adults received A-F Betafood&reg, or placebo for 12 weeks. Gallbladder function as assessed by gallbladder volume, ejection fraction (GBEF), ejection rate, wall thickness and liver function determined via aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyltransferase, and high-sensitivity c-reactive protein analysis at baseline and week 12 were the primary outcomes. Total cholesterol, low-density lipoprotein-cholesterol, high-density lipoprotein-cholesterol, triglycerides, and oxidative stress markers including oxidized low-density lipoprotein, tumor necrosis factor-&alpha, adiponectin and malonyldialdehyde (MDA) were assessed as secondary outcomes. A-F Betafood&reg, supplementation significantly reduced gallbladder wall thickness (p = 0.049) by 9% compared to placebo from baseline to week 12. The A-F Betafood&reg, group alone had significant improvements in gallbladder volume (32%, p = 0.044) and GBEF (19%, p = 0.047) at week 12. There were no changes in liver function, oxidative stress markers or blood lipid concentrations, though MDA concentrations decreased in both groups. Our findings demonstrate A-F Betafood&reg, supplementation significantly improves measures of gallbladder function and support healthy gallbladder function in the individuals with gall bladder condition.

The objective of this study was to investigate the effect of a broad-spectrum wellness beverage (Zeal Wellness [ZW]) on standardized measures of mood states, including overall feelings of vitality, in healthy, moderately stressed adults.A randomized, double-blind, placebo-controlled clinical trial was conducted among 99 eligible participants prescreened for moderate stress. Participants were randomized to one of four groups and received ZW once daily (1-dose-ZW; 14 g), ZW twice daily (2-dose-ZW; 28 g), placebo once daily (1-dose-placebo), or placebo twice daily (2-dose-placebo) for 4 weeks. A stress/vitality questionnaire assessed stress and the Profile of Moods (POMS) Questionnaire assessed vigor via mental/physical energy and global mood state. Safety was assessed by clinical chemistry, liver, kidney function, and anthropometric measures and adverse event reporting.Participants receiving 2-dose-ZW reported a 6.6% decrease in scores on POMS-Total Mood Disturbance (TMD; p0.05) and a 6.8% decrease in the anger-hostility mood state (p0.022) compared to the combined placebo group at day 29. The 2-dose-ZW provided a 12.8% greater improvement in POMS-TMD scores when compared to participants receiving 1-dose-ZW after 28 days of supplementation (p = 0.014). Within groups, there was a 22.4% and a 9.6% decrease in POMS-TMD scores in participants with 2-dose-ZW and 1-dose-ZW, respectively. In addition, participants receiving 2-dose-ZW showed significant improvements (p = 0.001) in the POMS t-score iceberg profile, which represented a shift to a more healthy profile.These data show that daily supplementation with 2-dose-ZW significantly decreased POMS-TMD scores and anger-hostility mood state and shifted the POMS iceberg profile to a healthy profile compared to the combined placebo, reflecting the functional benefit of rice-bran-fruit-vegetable extracts based beverage on health.

Bloating is a common yet poorly managed complaint among healthy people, with a complex etiology that impacts health and general well-being. The study intended to evaluate the efficacy and safety of supplementation with a probiotic, Bacillus subtilis MB40 (MB40), on bloating, abdominal discomfort, and gas in healthy participants.In this multi-center, double-blind, placebo-controlled, parallel trial, 100 participants were randomized to receive either MB40 at 5 × 109 colony forming units (CFU; n = 50) or a placebo (n = 50) once daily for 4-weeks. Participants completed 3 questionnaires daily: a modified Abdominal Discomfort, Gas, and Bloating (mADGB) questionnaire, a modified Gastrointestinal Symptoms Rating Scale (mGSRS), and a Bowel Habits Diary (BHD). Participants' responses to each question were combined into weekly averages.At the end of 4-weeks, there were no significant differences in average weekly change in daily bloating intensity, number of days with and duration of bloating, abdominal discomfort and gas between MB40 and placebo groups. However, the male sub-group on MB40 achieved clinical thresholds with a greater decrease over placebo in the intensity of (1.38) and number of days with (1.32) bloating, the number of days (1.06) and duration (86-minutes) of gas, the number of days with abdominal discomfort (1.32) and diarrhea symptom score (1.02). Role limitation (physical; P = .026), vitality (P = .034) and social functioning (P = .037) were significantly improved from baseline to week 4 in the MB40 group. At 2-weeks, physical functioning (P = .017) significantly improved in the MB40 group versus placebo.Although MB40 supplementation did not significantly improve bloating across all populations, the male sub-group demonstrated clinically significant reductions in bloating intensity, number of days with abdominal discomfort, gas, bloating, and duration of gas, compared to placebo. Additionally, the male sub-group receiving MB40 had a 10% improvement in general health score. MB40 supplementation at a dose of 5 × 109 CFU daily for 4-weeks was also safe and well-tolerated as all biometric, vital, and hematological measures remained within normal laboratory ranges (Clinical Trials NCT02950012).

Euglena gracilis produce high amounts of algal β-1,3-glucan, which evoke an immune response when consumed. This study investigated the effect of supplementation with a proprietary Euglena gracilis fermentate (BG), containing greater than 50% β-1,3-glucan, on immune function as measured by self-reported changes in upper respiratory tract infection (URTI) symptoms. Thirty-four healthy, endurance-trained participants were randomized and received either 367 mg of BG or placebo (PLA) for 90 days. Symptoms were assessed by the 24-item Wisconsin Upper Respiratory Symptom Survey and safety via clinical chemistry, hematology, vitals, and adverse event reporting. Participants supplemented with BG over 90 days reported fewer sick days (BG: 1.46 ± 1.01; PLA: 4.79 ± 1.47 days; p = 0.041), fewer URTI symptoms (BG: 12.62 ± 5.92; PLA: 42.29 ± 13.17; p = 0.029), fewer symptom days (BG: 5.46 ± 1.89; PLA: 15.43 ± 4.59 days; p = 0.019), fewer episodes (BG: 2.62 ± 0.67; PLA: 4.79 ± 0.67; p = 0.032), and lower global severity measured as area under curve for URTI symptoms (BG: 17.50 ± 8.41; PLA: 89.79 ± 38.92; p = 0.0499) per person compared to placebo. Sick days, symptoms, and global severity were significantly (p < 0.05) fewer over 30 days in the BG group compared to PLA. All safety outcomes were within clinically normal ranges. The study provides evidence that supplementation with a proprietary Euglena gracilis fermentate containing greater than 50% β-1,3-glucan may reduce and prevent URTI symptoms, providing immune support and protecting overall health.

Cannabis (also known as marijuana) is the most frequently used psychoactive substance globally. Cannabis exerts therapeutic functions for many indications and has vast potential as a health and wellness product. Advances in our understanding of the composition and pharmacological properties of cannabis have revealed interactions between cannabis, an individuals’ circadian rhythms and their endocannabinoid signaling. Exogenously administered cannabinoids can bidirectionally entrain central and peripheral clocks that comprise circadian rhythms, and malfunctions in the endocannabinoid system are reported to impact neurological processes. Therefore, it is necessary to account for the circadian rhythm when designing clinical trials examining the pharmacological properties of cannabis-based products for health and wellness to limit its potential confounding impact on results. Consideration of the entrainment capabilities of the endocannabinoid system is warranted when designing clinical trials.

OBJECTIVES: Design of aggregated N-of-1 trials with the intent of identifying individuals’ unique response to probiotics by studying each individual directly. Consideration of their biochemical uniqueness will ensure sufficient data are collected on each individual to make unequivocal claims on their responses to probiotics. METHODS: In the aggregate N-of-1 trial design, measurements taken will encompass multivariate outcomes including monitoring weight, microbiome species abundance in total fecal DNA for quantitative metagenomics to evaluate microbial gene richness and quantification of short chain fatty acids; influence of probiotics on mood, cognition, depression and sleep may be measured using wireless devices. RESULTS: A pragmatic analysis approach will provide information beyond significant differences in outcomes from baseline, as well, identifying variation around outcomes for the individual. Decreasing variation over time would suggest a more stable state for a particular outcome. Data from a series of sophisticated N-of-1 studies will, therefore, provide a scientifically sound basis for the creation of a global index detailing the relationship between a nutritional response and genetic features, biochemical, behavioural and exposure levels. Physicians and health care providers can leverage this data to decide on how to manage a patient's condition, while nutraceutical companies can make more specific claims for their products. CONCLUSIONS: N-of-1 trials are a logical extension to clinical practice as physicians deal with patients as individuals with unique characteristics and treatment algorithms in a traditional clinical care setting using patient outcomes to decide if the intervention worked. N-of-1 trials and aggregated N-of-1 trials help identify factors that influence responses to nutrition that may be shared among individuals. Results from N-of-1 trials may be effectively used in Augmented Randomized double-blind Clinical Trial design to identify responders with a goal in formulating successful probiotic interventions.

Broad-spectrum antibiotic use can disrupt the gastrointestinal microbiota resulting in diarrhoea. Probiotics may be beneficial in managing this type of diarrhoea. The aim of this 10-week randomised, double-blind, placebo-controlled, parallel study was to investigate the effect ofLactobacillus helveticusR0052 andLactobacillus rhamnosusR0011 supplementation on antibiotic-associated diarrhoea in healthy adults. Subjects were randomised to receive 1 week of amoxicillin–clavulanic acid (875 mg/125 mg) once per day, plus a daily dose of 8×109colony-forming units of a multi-strain probiotic (n80) or placebo (n80). The probiotic or placebo intervention was maintained for 1 week after completion of the antibiotic. Primary study outcomes of consistency and frequency of bowel movements were not significantly different between the probiotic and placebo groups. The secondary outcomes of diarrhoea-like defecations, Gastrointestinal Symptoms Rating Scale scores, safety parameters and adverse events were not significantly different between the probiotic intervention and the placebo. Apost hocanalysis on the duration of diarrhoea-like defecations showed that probiotic intervention reduced the length of these events by 1 full day (probiotic, 2·70(sem0·36) d; placebo, 3·71 (sem0·36) d;P=0·037; effect size=0·52). In conclusion, this study provides novel evidence thatL. helveticusR0052 andL. rhamnosusR0011 supplementation significantly reduced the duration of diarrhoea-like defecations in healthy adults receiving antibiotics.

OBJECTIVES: With federal legalization of cannabis in Canada and hemp in the USA, there is much interest in consumer demographics and use patterns. The objective of this study was to examine gender differences in cannabis use patterns and demographics in Southwestern Ontario, Canada. METHODS: A 31 question, online market research survey was conducted on past and present cannabis use from March 2018 to October 2019, including Canadian respondents before and after federal cannabis legalization. The associations between gender and self-reported use reason and frequency, route of administration, cannabinoid, and life stage when starting were assessed. Possible differences were assessed by the Chi Square test and two sample t-test (age only). RESULTS: There were 2264 male and 1830 female respondents to the survey, with an average age of 34 ± 13 years. Across genders, the majority of users first started in high school (59.5%). Gender was associated with frequency of use (P

Specific probiotic strains can alleviate the gastrointestinal (GI) symptoms and psychiatric comorbidities of irritable bowel syndrome (IBS). In this randomized, double-blind, placebo-controlled study, the efficacy of Lactobacillus paracasei HA-196 (L. paracasei) and Bifidobacterium longum R0175 (B. longum) in reducing the GI and psychological symptoms of IBS was evaluated in 251 adults with either constipation (IBS-C), diarrhea (IBS-D), or mixed-pattern (IBS-M). Following a 2-week run-in period, participants were randomized to one of three interventions: L. paracasei (n = 84), B. longum (n = 83) or placebo (n = 81). IBS symptoms, stool frequency and consistency and quality of life were assessed by questionnaires. The differences from baseline in the severity of IBS symptoms at 4 and 8 weeks were similar between groups. Participants in this study were classified, after randomization, into subtypes according to Rome III. Within the L. paracasei group, complete spontaneous and spontaneous bowel movement frequency increased in participants with IBS-C (n = 10) after 8 weeks of supplementation (both p &lt, 0.05) and decreased in participants with IBS-D (n = 10, p = 0.013). Both L. paracasei and B. longum supplementation improved the quality of life in emotional well-being and social functioning compared with baseline (all p &lt, 0.05). In conclusion, L. paracasei and B. longum may reduce GI symptom severity and improve the psychological well-being of individuals with certain IBS subtypes.

Background. Anthocyanins and prebiotics impact overall health and wellness, likely through modulation of the microbiota and the intestinal ecosystem. Objectives. An 8-week open-label study in male and female volunteers with uncomplicated obesity was designed to study the efficacy of an anthocyanin and prebiotic blend in modulating intestinal microbiota and intestinal inflammation. Results. After 8 weeks of daily supplementation, participants had a significant decrease in Firmicutes (p<0.001) and Actinobacteria (p<0.001) and a significant increase in Bacteroidetes (p<0.001). Bowel habits were improved as evidenced by reductions in the severity of bloating (p<0.05), gas (p=0.035), and abdominal pain (p=0.015) as well as significant improvements in stool consistency (p<0.05). Finally, a nonsignificant decrease in the inflammatory marker fecal calprotectin was seen (p=0.107). The supplement was safe and well tolerated. Conclusions. The results suggest that regular consumption of the anthocyanin-prebiotic blend positively modulated the intestinal ecosystem and provided insights into the mechanisms of action and its impact on health benefits.
