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 the SYDNEY 2 trial (PMID 17065669), which gave 181 people with diabetic polyneuropathy 600, 1,200 or 1,800 mg once daily or placebo for 5 weeks. All three doses beat placebo on the Total Symptom Score, with about the same size of effect: responder rates (a 50% or greater fall) were 62%, 50% and 56% against 26% on placebo, and effectiveness here is the responder rate above placebo. Nausea, vomiting and vertigo rose with dose, and the authors judged 600 mg once daily the best balance of benefit and risk. Doses below 600 mg were not tested. A 6-month trial of 1,200 mg a day in 200 patients (PMID 32370731) found benefit with mild nausea in 6 patients and no withdrawals, which is the basis for the 1,200 mg ceiling. A meta-analysis of 10 trials reported a dose-related trend in symptom scores (PMID 37630823), which the one head-to-head dose trial did not show.
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.
