Each block is one evidence row, sized by how many people it enrolled, with its grade inside. Outlined: mixed results.

From the rows

The best-graded row, grade C, is a meta-analysis of 597 people (2024) and reported mixed results.

The rows run from 16 to 597 people, published from 2022 to 2024: 1 pooled review and 1 single study.

Single pre-exercise serving (amount not stated in the abstract) · One session per condition, 1-week washout
Sprint times were 1.9–3.4% faster than placebo in the last sprints of a 15-sprint test; blood lactate and perceived exertion did not differ.

Meta-analysis, 27 studies · n 597 · 2024 · Healthy adults
Varied across trials · Varied across trials
No significant effect on VO2max, aerobic or 30-second anaerobic endurance, or muscle strength. Lower-limb explosive power rose slightly (SMD 0.30), and perceived exertion and blood lactate during exercise were lower (SMD −0.37 each).
