This study aimed to systematically review existing randomized clinical trials on the effect of dietary interventions on endometriosis. A search was performed on the Cochrane Central Register of Controlled Trials (CENTRAL), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Clinical Trials, EMBASE, PubMed, Lilacs, and Cielo databases. The search terms were used: "endometriosis", "endometrioma", "diet", "supplements" and "nutrition". Electronic literature searches through databases yielded 866 publications. Two authors performed The study selection independently (and blinded), and disagreements were discussed. Eleven RCTs were included in the systematic review, with 716 women randomized. Most studies reported a positive effect on endometriosis pain scores; however, they were characterized by moderate or high-risk bias. Of these, six RCTs, including 457 women with endometriosis, were included in the meta-analysis. Compared with Placebo, antioxidant use was associated with a reduction in dysmenorrhea (mean difference - 1.95 [CI 95%, -3.78 to -0.13]. Supplementation was not significant for reducing chronic pelvic pain (mean difference - 2.22 [95% CI, -4.99 to 0.55] and dyspareunia (MD - 2.56 [95% CI, - 5. 22 to 0.10]. Both analyses showed a high degree of heterogeneity. Moreover, studies with low risk of bias did not show significant results compared to those on Placebo. The effects of nutrient compounds seem to have the potential to reduce pain in women with endometriosis, mainly to reduce dysmenorrhea. However, the available studies present high heterogeneity and moderate/high risk of bias. More randomized clinical trials are needed to accurately determine dietary interventions' short- and long-term efficacy and safety in managing endometriosis pain., Competing Interests: Declarations. Conflict of Interest: There is no type of conflict of interest with the participants or any other collaborator, direct or indirect, for the development of this study., (© 2024.

Objective: The aim of this study was to examine the effects of eating dried figs on the symptoms of primary dysmenorrhea, perceived stress levels, and quality of life during all menstrual cycles., Methods: This randomized, placebo-controlled study was performed with 99 midwifery students. Each student was randomly assigned to the placebo (n = 32), cinnamon (n = 34), or dried fig (n = 33) groups. Data were gathered through the Total Dysmenorrhea Score, a descriptive information form, the Visual Analogue Scale, a pain duration assessment form, the Menstrual Distress Questionnaire, the Perceived Stress Scale, and the short version of the World Health Organization Quality of Life Scale-TR., Results: During the 3 menstrual cycles in which the intervention was implemented, the dried-fig group had significantly lower scores for pain severity and duration, menstrual distress, and perceived stress than did those of the cinnamon and placebo groups. In addition, during these 3 cycles, the dried-fig group had significantly higher quality-of-life scores than the cinnamon and placebo groups., Conclusion: The results showed that eating dried figs during menstruation decreased pain severity and duration, menstrual symptoms, and perceived stress and increased quality of life.

Background: Primary dysmenorrhea is common among young girls and childbearing women. Dysmenorrhea is a painful contraction of uterus which occurs in the beginning of bleeding or before the menstrual cycle begins. Regarding the mechanism of calcium in response to hormonal change and the role of fish oil on reducing prostaglandins, we compared the effectiveness of fish-oil and calcium supplementation in treating primary dysmenorrheal., Methods: This randomized double-blinded clinical trial was conducted on women aged 18 to 45 years with moderate to severe primary dysmenorrhea symptoms from January 2015 to March 2015. The women were randomly divided to two groups (fish oil and calcium). The drugs were given every day in the first cycle and from 8 days before till 2 days after initiation of menstruation for the second and third cycles. The intensity of pain and other symptoms of dysmenorreha were recorded and data were analyzed in SPSS 16 using T-test and X2 tests. Significant level was considered to be less than 0.05., Results: The mean ± SD age of the patients in the fish oil group was 25.0±4.3 and in calcium group was 25.48±6.6 years. According to this result, there was no statistically significant difference in the intensity of pain between fish-oil group and calcium group before and 1 month after the study (P>0.05). However, there was statistically significant difference between fish-oil group and calcium group before the study and 2 months (P=0.001) and 3 months after study (p<0.001). Besides, the fishoil patients needed less analgesic as compared to the calcium patients., Conclusion: It is concluded that omega-3 is more effective than calcium, what can be justified by pain mechanisms and symptoms pathology in dysmenorrheal., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.)

Background: Dysmenorrhoea refers to painful menstrual cramps and is a common gynaecological complaint. Conventional treatments include non-steroidal anti-inflammatory drugs (NSAIDs) and oral contraceptive pills (OCPs), which both reduce myometrial activity (contractions of the uterus). A suggested alternative approach is dietary supplements. We used the term 'dietary supplement' to include herbs or other botanical, vitamins, minerals, enzymes, and amino acids. We excluded traditional Chinese medicines., Objectives: To determine the efficacy and safety of dietary supplements for treating dysmenorrhoea., Search Methods: We searched sources including the Cochrane Gynaecology and Fertility Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, AMED, PsycINFO (all from inception to 23 March 2015), trial registries, and the reference lists of relevant articles., Selection Criteria: We included randomised controlled trials (RCTs) of dietary supplements for moderate or severe primary or secondary dysmenorrhoea. We excluded studies of women with an intrauterine device. Eligible comparators were other dietary supplements, placebo, no treatment, or conventional analgesia., Data Collection and Analysis: Two review authors independently performed study selection, performed data extraction and assessed the risk of bias in the included trials. The primary outcomes were pain intensity and adverse effects. We used a fixed-effect model to calculate odds ratios (ORs) for dichotomous data, and mean differences (MDs) or standardised mean differences (SMDs) for continuous data, with 95% confidence intervals (CIs). We presented data that were unsuitable for analysis either descriptively or in additional tables. We assessed the quality of the evidence using Grading of Recommendations Assessment, Development and Evaluation (GRADE) methods., Main Results: We included 27 RCTs (3101 women). Most included studies were conducted amongst cohorts of students with primary dysmenorrhoea in their late teens or early twenties. Twenty-two studies were conducted in Iran and the rest were performed in other middle-income countries. Only one study addressed secondary dysmenorrhoea. Interventions included 12 different herbal medicines (German chamomile (Matricaria chamomilla, M recutita, Chamomilla recutita), cinnamon (Cinnamomum zeylanicum, C. verum), Damask rose (Rosa damascena), dill (Anethum graveolens), fennel (Foeniculum vulgare), fenugreek (Trigonella foenum-graecum), ginger (Zingiber officinale), guava (Psidium guajava), rhubarb (Rheum emodi), uzara (Xysmalobium undulatum), valerian (Valeriana officinalis), and zataria (Zataria multiflora)) and five non-herbal supplements (fish oil, melatonin, vitamins B1 and E, and zinc sulphate) in a variety of formulations and doses. Comparators included other supplements, placebo, no treatment, and NSAIDs.We judged all the evidence to be of low or very low quality. The main limitations were imprecision due to very small sample sizes, failure to report study methods, and inconsistency. For most comparisons there was only one included study, and very few studies reported adverse effects. Effectiveness of supplements for primary dysmenorrhoea We have presented pain scores (all on a visual analogue scale (VAS) 0 to 10 point scale) or rates of pain relief, or both, at the first post-treatment follow-up. Supplements versus placebo or no treatmentThere was no evidence of effectiveness for vitamin E (MD 0.00 points, 95% CI -0.34 to 0.34; two RCTs, 135 women).There was no consistent evidence of effectiveness for dill (MD -1.15 points, 95% CI -2.22 to -0.08, one RCT, 46 women), guava (MD 0.59, 95% CI -0.13 to 1.31; one RCT, 151 women); one RCT, 73 women), or fennel (MD -0.34 points, 95% CI -0.74 to 0.06; one RCT, 43 women).There was very limited evidence of effectiveness for fenugreek (MD -1.71 points, 95% CI -2.35 to -1.07; one RCT, 101 women), fish oil (MD 1.11 points, 95% CI 0.45 to 1.77; one RCT, 120 women), fish oil plus vitamin B1 (MD -1.21 points, 95% CI -1.79 to -0.63; one RCT, 120 women), ginger (MD -1.55 points, 95% CI -2.43 to -0.68; three RCTs, 266 women; OR 5.44, 95% CI 1.80 to 16.46; one RCT, 69 women), valerian (MD -0.76 points, 95% CI -1.44 to -0.08; one RCT, 100 women), vitamin B1 alone (MD -2.70 points, 95% CI -3.32 to -2.08; one RCT, 120 women), zataria (OR 6.66, 95% CI 2.66 to 16.72; one RCT, 99 women), and zinc sulphate (MD -0.95 points, 95% CI -1.54 to -0.36; one RCT, 99 women).Data on chamomile and cinnamon versus placebo were unsuitable for analysis. Supplements versus NSAIDSThere was no evidence of any difference between NSAIDs and dill (MD 0.13 points, 95% CI -1.01 to 1.27; one RCT, 47 women), fennel (MD -0.70 points, 95% CI -1.81 to 0.41; one RCT, 59 women), guava (MD 1.19, 95% CI 0.42 to 1.96; one RCT, 155 women), rhubarb (MD -0.20 points, 95% CI -0.44 to 0.04; one RCT, 45 women), or valerian (MD points 0.62 , 95% CI 0.03 to 1.21; one RCT, 99 women),There was no consistent evidence of a difference between Damask rose and NSAIDs (MD -0.15 points, 95% CI -0.55 to 0.25; one RCT, 92 women).There was very limited evidence that chamomile was more effective than NSAIDs (MD -1.42 points, 95% CI -1.69 to -1.15; one RCT, 160 women). Supplements versus other supplementsThere was no evidence of a difference in effectiveness between ginger and zinc sulphate (MD 0.02 points, 95% CI -0.58 to 0.62; one RCT, 101 women). Vitamin B1 may be more effective than fish oil (MD -1.59 points, 95% CI -2.25 to -0.93; one RCT, 120 women). Effectiveness of supplements for secondary dysmenorrhoea There was no strong evidence of benefit for melatonin compared to placebo for dysmenorrhoea secondary to endometriosis (data were unsuitable for analysis). Safety of supplements Only four of the 27 included studies reported adverse effects in both treatment groups. There was no evidence of a difference between the groups but data were too scanty to reach any conclusions about safety., Authors' Conclusions: There is no high quality evidence to support the effectiveness of any dietary supplement for dysmenorrhoea, and evidence of safety is lacking. However for several supplements there was some low quality evidence of effectiveness and more research is justified.

Purpose of Review: Apart from the well known effects of vitamin D on maintaining calcium homeostasis and promoting bone mineralization, there is some evidence suggesting that vitamin D also modulates human reproductive processes. We will review the most interesting and relevant studies on vitamin D and female fertility published over the past year., Recent Findings: In the past year, several observational studies reported a better in-vitro fertilization outcome in women with sufficient vitamin D levels (≥30 ng/ml), which was mainly attributed to vitamin D effects on the endometrium. One randomized controlled trial found an increased endometrial thickness in women with polycystic ovary syndrome (PCOS) receiving vitamin D during intrauterine insemination cycles. Further, vitamin D supplementation had a beneficial effect on serum lipids in PCOS women. Vitamin D treatment improved endometriosis in a rat model and increased vitamin D intake was related to a decreased risk of incident endometriosis. Vitamin D was also favorably associated with primary dysmenorrhea, uterine leiomyoma, and ovarian reserve in late reproductive aged women., Summary: In women undergoing in-vitro fertilization, a sufficient vitamin D level (≥30 ng/ml) should be obtained. Vitamin D supplementation might improve metabolic parameters in women with PCOS. A high vitamin D intake might be protective against endometriosis.

Fatty acids, which are the essential nutrients for humans, are an important source of energy and an essential component of cell membranes. They also function as signal transduction molecules in a range of biological phenomena. Recently, an increasing number of physiologic and pharmacologic reports on fatty acids have improved our understanding of the association of fatty acids with certain diseases. It has also become apparent that functional properties of fatty acids are modulated by factors such as the amount of individual fatty acid intake and their distribution among organs. Recently, the functional relationship between polyunsaturated fatty acids and pain has been the focus of many studies. Both basic and clinical studies have shown that a dietary intake of n-3 series polyunsaturated fatty acids results in a reduction in the pain associated with rheumatoid arthritis, dysmenorrhea, inflammatory bowl disease, and neuropathy. In addition, levels of n-6 series polyunsaturated fatty acids are high in patients with chronic pain. These results indicate that polyunsaturated fatty acids play a vital role in pain regulation. In this review, we summarize a number of basic and clinical studies on polyunsaturated fatty acids and their association with pain.

Objective: To evaluate the effectiveness for the outcomes of endometriosis-related pain and quality of life of conservative surgery plus placebo compared with conservative surgery plus hormonal suppression treatment or dietary therapy., Design: Randomized comparative trial., Setting: University hospital., Patient(s): Two hundred twenty-two consecutive women who underwent conservative pelvic surgery for symptomatic endometriosis stage III-IV (r-AFS)., Intervention(s): Six months of placebo (n = 110) versus GnRH-a (tryptorelin or leuprorelin, 3.75 mg every 28 days) (n = 39) or continuous estroprogestin (ethynilestradiol, 0.03 mg plus gestoden, 0.75 mg) (n = 38) versus dietary therapy (vitamins, minerals salts, lactic ferments, fish oil) (n = 35)., Main Outcome Measure(s): Painful symptoms (visual analogue scale score) and quality-of-life endometriosis-related symptoms (SF-36 score) at 12 months' follow-up., Result(s): Patients treated with postoperative hormonal suppression therapy showed less visual analogue scale scores for dysmenorrhoea than patients of the other groups. Hormonal suppression therapy and dietary supplementation were equally effective in reducing nonmenstrual pelvic pain. Surgery plus placebo showed significative decrease in dyspareunia scores. Postoperative medical and dietary therapy allowed a better quality of life than placebo., Conclusion(s): Postoperative hormonal suppression treatment or dietary therapy are more effective than surgery plus placebo to obtain relief of pain associated with endometriosis stage III-IV and improvement of quality of life.

The omega-3 fatty acids docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are orthomolecular, conditionally essential nutrients that enhance quality of life and lower the risk of premature death. They function exclusively via cell membranes, in which they are anchored by phospholipid molecules. DHA is proven essential to pre- and postnatal brain development, whereas EPA seems more influential on behavior and mood. Both DHA and EPA generate neuroprotective metabolites. In double-blind, randomized, controlled trials, DHA and EPA combinations have been shown to benefit attention deficit/hyperactivity disorder (AD/HD), autism, dyspraxia, dyslexia, and aggression. For the affective disorders, meta-analyses confirm benefits in major depressive disorder (MDD) and bipolar disorder, with promising results in schizophrenia and initial benefit for borderline personality disorder. Accelerated cognitive decline and mild cognitive impairment (MCI) correlate with lowered tissue levels of DHA/EPA, and supplementation has improved cognitive function. Huntington disease has responded to EPA. Omega-3 phospholipid supplements that combine DHA/EPA and phospholipids into the same molecule have shown marked promise in early clinical trials. Phosphatidylserine with DHA/EPA attached (Omega-3 PS) has been shown to alleviate AD/HD symptoms. Krill omega-3 phospholipids, containing mostly phosphatidylcholine (PC) with DHA/EPA attached, markedly outperformed conventional fish oil DHA/EPA triglycerides in double-blind trials for premenstrual syndrome/dysmenorrhea and for normalizing blood lipid profiles. Krill omega-3 phospholipids demonstrated anti-inflammatory activity, lowering C-reactive protein (CRP) levels in a double-blind trial. Utilizing DHA and EPA together with phospholipids and membrane antioxidants to achieve a triple cell membrane synergy may further diversify their currently wide range of clinical applications.

The objective of this study is to assess the literature concerning the effect of diet on endometriosis and dysmenorrhea and to elucidate evidential support, to give dietary recommendations to women suffering from these conditions. A systematic search in electronic databases on a relationship between diet and endometriosis/dysmenorrhea was performed. Data on diet and endometriosis were limited to four trials of which two were animal studies. The articles concerning human consumption found some relation between disease and low intake of vegetable and fruit and high intake of vegetarian polyunsaturated fat, ham, beef and other red meat. Results concerning fish intake were not consistent. Eight trials of different design, with a total of 1097 women, investigated the relationship between diet and dysmenorrhea. Intake of fish oil seemed to have a positive effect on pain symptoms. This study concludes that literature on diet and endometriosis is sparse, whereas eight studies have looked at diet and dysmenorrhea. No clear recommendations on what diet to eat or refrain from to reduce the symptoms of endometriosis can be given, while a few studies indicate that fish oil can reduce dysmenorrhea. Further research is recommended on both subjects.

Background: Dysmenorrhoea refers to the occurrence of painful menstrual cramps of uterine origin and is a common gynaecological complaint. Common treatment for dysmenorrhoea is medical therapy such as nonsteroidal anti-inflammatories (NSAIDs) or oral contraceptive pills (OCPs) which both work by reducing myometrial activity (contractions of the uterus). The efficacy of conventional treatments such as nonsteroidals is considerable, however the failure rate is still often 20-25%. Many consumers are now seeking alternatives to conventional medicine and research into the menstrual cycle suggests that nutritional intake and metabolism may play an important role in the cause and treatment of menstrual disorders. Herbal and dietary therapies number among the more popular complementary medicines yet there is a lack of taxonomy to assist in classifying them. In the US, herbs and other phytomedicinal products (medicine from plants) have been legally classified as dietary supplements since 1994. Included in this category are vitamins, minerals, herbs or other botanicals, amino acids and other dietary substances. For the purpose of this review we use the wider term herbal and dietary therapies to include the assorted herbal or dietary treatments that are classified in the US as supplements and also the phytomedicines that may be classified as drugs in the European Union., Objectives: To determine the efficacy and safety of herbal and dietary therapies for the treatment of primary and secondary dysmenorrhoea when compared to each other, placebo, no treatment or other conventional treatments (e.g. NSAIDS)., Search Strategy: Electronic searches of the Cochrane Menstrual Disorders and Subfertility Group Register of controlled trials, CCTR, MEDLINE, EMBASE, CINAHL, Bio extracts, and PsycLIT were performed to identify relevant randomised controlled trials (RCTs). The Cochrane Complementary Medicine Field's Register of controlled trials (CISCOM) was also searched. Attempts were also made to identify trials from the National Research Register, the Clinical Trial Register and the citation lists of review articles and included trials. In most cases, the first or corresponding author of each included trial was contacted for additional information., Selection Criteria: The inclusion criteria were RCTs of herbal or dietary therapies as treatment for primary or secondary dysmenorrhoea vs each other, placebo, no treatment or conventional treatment. Interventions could include, but were not limited to, the following; vitamins, essential minerals, proteins, herbs, and fatty acids. Exclusion criteria were: mild or infrequent dysmenorrhoea or dysmenorrhoea from an IUD., Data Collection and Analysis: Seven trials were included in the review. Quality assessment and data extraction were performed independently by two reviewers. The main outcomes were pain intensity or pain relief and the number of adverse effects. Data on absence from work and the use of additional medication was also collected if available. Data was combined for meta-analysis using Peto odds ratios for dichotomous data or weighted mean difference for continuous data. A fixed effects statistical model was used. If data suitable for meta-analysis could not be extracted, any available data from the trial was extracted and presented as descriptive data., Main Results: MAGNESIUM: Three small trials were included that compared magnesium and placebo. Overall magnesium was more effective than placebo for pain relief and the need for additional medication was less. There was no significant difference in the number of adverse effects experienced. VITAMIN B6: One small trial of vitamin B6 showed it was more effective at reducing pain than both placebo and a combination of magnesium and vitamin B6. MAGNESIUM AND VITAMIN B6: Magnesium was shown to be no different in pain outcomes from both vitamin B6 and a combination of vitamin B6 and magnesium by one small trial. The same trial also showed that a combination of magnesium and vitamin B6 was no different from placebo in reducing pain. VITAMIN B1: One large trial showed vitamin B1 to be more effective than placebo in reducing pain. VITAMIN E: One small trial comparing a combination of vitamin E (taken daily) and ibuprofen (taken during menses) versus ibuprofen (taken during menses) alone showed no difference in pain relief between the two treatments. OMEGA-3 FATTY ACIDS: One small trial showed fish oil (omega-3 fatty acids) to be more effective than placebo for pain relief. JAPANESE HERBAL COMBINATION: One small trial showed the herbal combination to be more effective for pain relief than placebo, and less additional pain medication was taken by the treatment group., Reviewer's Conclusions: Vitamin B1 is shown to be an effective treatment for dysmenorrhoea taken at 100 mg daily, although this conclusion is tempered slightly by its basis on only one large RCT. Results suggest that magnesium is a promising treatment for dysmenorrhoea. It is unclear what dose or regime of treatment should be used for magnesium therapy, due to variations in the included trials, therefore no strong recommendation can be made until further evaluation is carried out. Overall there is insufficient evidence to recommend the use of any of the other herbal and dietary therapies considered in this review for the treatment of primary or secondary dysmenorrhoea.

Objective: To test the hypothesis that a low-fat, vegetarian diet reduces dysmenorrhea and premenstrual symptoms by its effect on serum sex-hormone binding globulin concentration and estrogen activity., Methods: In a crossover design, 33 women followed a low-fat, vegetarian diet for two menstrual cycles. For two additional cycles, they followed their customary diet while taking a supplement placebo pill. Dietary intake, serum sex-hormone binding globulin concentration, body weight, pain duration and intensity, and premenstrual symptoms were assessed during each study phase., Results: Mean (+/- standard deviation [SD]) serum sex-hormone binding globulin concentration was higher during the diet phase (46.7 +/- 23.6 nmol/L) than during the supplement phase (39.3 +/- 19.8 nmol/L, P < .001). Mean (+/- SD) body weight was lower during the diet (66.1 +/- 11.3 kg) compared with the supplement phase (67.9 +/- 12.1 kg, P < .001). Mean dysmenorrhea duration fell significantly from baseline (3.9 +/- 1.7 days) to diet phase (2.7 +/- 1.9 days) compared with change from baseline to supplement phase (3.6 +/- 1.7 days, P < .01). Pain intensity fell significantly during the diet phase, compared with baseline, for the worst, second-worst, and third-worst days, and mean durations of premenstrual concentration, behavioral change, and water retention symptoms were reduced significantly, compared with the supplement phase., Conclusion: A low-fat vegetarian diet was associated with increased serum sex-hormone binding globulin concentration and reductions in body weight, dysmenorrhea duration and intensity, and premenstrual symptom duration. The symptom effects might be mediated by dietary influences on estrogen activity.

Objectives: The purpose of the study was to examine whether dietary supplementation with omega-3 fatty acids can relieve symptoms of dysmenorrhea in adolescents., Study Design: Forty-two adolescents with dysmenorrhea were randomly allocated to two groups. In the first group 21 girls received fish oil (1080 mg icosapentaenoic acid, 720 mg docosahexaenoic acid, and 1.5 mg vitamin E) daily for 2 months followed by a placebo for an additional 2 months. In the second group 21 girls received placebo for the first 2 months, followed by fish oil for 2 more months. The Cox Menstrual Symptom Scale was used to assess response to treatment., Results: There were no significant differences in the Cox Menstrual Symptom Scale between the two groups at baseline after 2 months of placebo administration. After 2 months of treatment with fish oil there was a marked reduction in the Cox Menstrual Symptom Scale from a baseline mean value of 69.9 to 44.0 (p < 0.0004)., Conclusions: This study suggests that dietary supplementation with omega-3 fatty acids has a beneficial effect on symptoms of dysmenorrhea in adolescents.

Objectives: The hypothesis tested was that menstrual discomfort, e.g. dysmenorrhoea, known to be prostaglandin-mediated, can be influenced by the dietary ratio of n-3 and n-6 polyunsaturated fatty acids. The prostaglandins derived from marine n-3 fatty acids are normally less aggressive and therefore expected to be associated with milder symptoms., Design: The question was surveyed in an epidemiological study based upon self-administered questionnaires concerning menstrual history, present symptoms, general health, socioeconomic factors, and general dietary habits. Two (prospective) 4-day dietary records were used to estimate average daily nutrient intake., Subjects: The subjects were recruited by advertising (about 220 volunteered); 181 healthy Danish women were selected, aged 20-45 years; they were not pregnant and did not use oral contraceptives., Results: No correlations were found between socioeconomic or anthropometric data and menstrual problems. On the contrary certain dietary habits, e.g. low intake of animal and fish products, and intakes of specific nutrients, were correlated with menstrual pain. The average dietary n-3/n-6 ratio of women with menstrual pain was 0.24. It was significantly higher among those with low intake of B12 coincident with low intake of n-3 (0.42, P < 0.001) (chi-square), with low n-3 intake coincident with low n-3/n-6 ratio (0.42, P < 0.005), and finally with low intake of B12 coincident with low n-3/n-6 ratio (0.47, P < 0.001)., Conclusion: The results were highly significant and mutually consistent and supported the hypothesis that a higher intake of marine n-3 fatty acids correlates with milder menstrual symptoms.
