Caffeine and taurine: a systematic review and network meta-analysis of their individual and combined effects on physical capacity, cognitive function, and physiological markers

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.
All three points come from one 4-week double-blind trial in newly diagnosed type 2 diabetes (PMID 21211558), which gave bitter melon 500, 1,000 or 2,000 mg a day against metformin 1,000 mg. Only 2,000 mg lowered fructosamine significantly (-10.2 µmol/L), and less than metformin did. 500 and 1,000 mg did not, so they are plotted as no effect. The trial had no placebo arm and did not test higher doses, so it cannot set an optimal dose or a safety ceiling. The Cochrane review (PMID 22895968, 4 trials, 479 participants) found no significant difference from placebo, and no two trials used the same preparation.
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.
