3 findings behind this formula. Hover a card for the detail and the source.
Meta-analysis of 13 RCTs (1,126 healthy and unwell people); CoQ10 significantly reduced fatigue scores versus placebo (Hedges' g -0.40), with greater benefit at higher doses and longer use.
Meta-analysis of 7 studies (103 people) using 1-6 g taurine a day for 1 day to 12 weeks; systolic and diastolic pressure each fell by about 3 mmHg, with no adverse events. Doses were higher than the 100 mg here.
Double-blind RCT in 80 adults aged 21-65 (73 completed); versus placebo, L-carnitine tartrate improved perceived recovery and soreness, lowered creatine kinase and blunted strength losses. Funded by an L-carnitine manufacturer.
