Temporary kidney dysfunction: Robuvit® supplementation in initial, transient kidney insufficiency and micro-macro albuminuria

BACKGROUND The aim of this study was to evaluate the efficacy of Robuvit® (French oak extract, Horphag Research) in improving kidney function in subjects with temporary kidney dysfunction (TKD) and increased oxidative stress levels. METHODS Fifty-seven subjects with TKD were included in the registry. Subjects were divided into two goups according to albumin levels in the urine. Plasma free radicals were measured in order to evaluate a possible connection with alterations in kidney function. Robuvit® was used at the dose of three capsules/day (300 mg/day) for 4 weeks. RESULTS Subjects with micro-albuminuria treated with Robuvit® improved significantly more than controls treated with standard management, achieving a full normalization of albumin levels in the urine (P
