Effect of a 12-mo intervention with whey protein powder on cognitive function in older adults with mild cognitive impairment: a randomized controlled trial
The American journal of clinical nutrition (2025) · Rct · n=107
The results also found a significant beneficial effect of the active intervention for several secondary cognitive outcomes such as Digit Symbol Substitution Test score, and the mean difference between groups in the ITT analysis was 2.72 (95% CI: 0.20, 5.23).
Caffeine and taurine: a systematic review and network meta-analysis of their individual and combined effects on physical capacity, cognitive function, and physiological markers
Journal of the International Society of Sports Nutrition (2025) · Meta analysis
Posterior estimates indicated that CAF+TAU was associated with a credible positive effect on anaerobic capacity (g = 0.46, 95% CrI [0.19, 0.71]) and reaction time (g = 0.75, 95% CrI [0.29, 1.18]) compared to CAF or TAU alone.
The points come from one dose-comparison trial, BENDIP (PMID 18473286): 165 people with diabetic polyneuropathy randomised to 300 mg, 600 mg or placebo for 6 weeks, 133 in the ITT analysis. The Neuropathy Symptom Score differed between groups in the per-protocol analysis (p=0.033) but only narrowly missed significance by intention to treat (p=0.055), and the Total Symptom Score did not differ. Improvement was more pronounced at 600 mg, and both doses were well tolerated. No higher dose was compared, so no optimal dose can be given. The minimum effective dose comes from a separate 3-week trial of 400 mg a day in 40 inpatients, where the neuropathy score and pain improved against placebo (PMID 15726875). At 300 mg a day for 24 months, a trial in 67 people with type 1 diabetes found no effect on peripheral nerve function (PMID 22446172).
Rests on two meta-analyses that state the dose range they cover. One (PMID 29546641, 10 studies, single doses or up to 2 weeks of 1 to 6 g a day) found endurance improved (Hedges' g 0.40) and that the dose did not change the size of the effect. The other (PMID 40852891, 23 randomised trials of a single dose, 308 participants) found a small-to-moderate overall gain (g 0.25, I² 61%), no significant dose-response within 1 to 6 g, and rated the certainty low to very low. So the curve is flat from 1 g to 6 g. No minimum, optimal or ceiling dose is set, because neither abstract reports an effect or safety at a single dose within the range.
AI-estimated from published studies. Interpret as directional guidance.
