Algal-oil capsules and cooked salmon: nutritionally equivalent sources of docosahexaenoic acid.
J Am Diet Assoc (2008) · Rct · n=32 healthy adults
Both sources raised plasma phospholipid DHA ~80% and erythrocyte DHA ~25%
Bioequivalence of docosahexaenoic acid from different algal oils in capsules and in a DHA-fortified food.
Lipids (2007) · Rct · n=60 (12 per group)
Algal DHA capsules and DHA-fortified food were bioequivalent for DHA delivery
High-fat meals rich in EPA plus DHA compared with DHA only have differential effects on postprandial lipemia and plasma 8-isoprostane F2alpha concentrations relative to a control high-oleic acid meal.
Am J Clin Nutr (2014) · Crossover · n=16 men
Fish oil (EPA+DHA) modestly reduced the postprandial triacylglycerol rise versus control
Dietary supplements for dysmenorrhoea

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).
Evaluation of the Efficacy of the Addition of a Combination of Pyrimidine Nucleotides and Vitamin B1 and B12 to Standard Treatment in the Management of Painful Radiculopathy and in the Quality of Life of Patients
Nutrients (2024) · Rct · n=122
Both groups showed pain improvement, but the VAS reduction (control: 24.58 vs. experimental: 31.35) was not statistically significant.
Efficacy of B-vitamins and vitamin D therapy in improving depressive and anxiety disorders: a systematic review of randomized controlled trials
Nutritional neuroscience (2023) · Systematic review · n=2256
Based on limited RCT evidence showing VAS pain reduction with B-vitamin combinations. Effect magnitude conservative due to mixed statistical significance. Higher bioavailability forms like benfotiamine likely more effective than standard thiamine HCl.
AI-estimated from published studies. Interpret as directional guidance.
Thiamine has a higher evidence score (7.5/10 vs 5.5/10) and wins in 2 of 3 categories.
