Acute L-arginine supplementation (6-8g) provides no ergogenic effect on strength training performance metrics such as muscular endurance, peak torque, or resistance rate.
If you are looking to improve your strength training performance (max reps, peak torque, or endurance), taking 6-8 grams of L-arginine shortly before your workout will not provide a performance benefit compared to a placebo. The current evidence does not support its use as an ergogenic aid for strength athletes.
Acute L-arginine supplementation provides no ergogenic effect on strength training performance.
Why this rating
Moderate quality evidence based on GRADE score, though limited by small sample size (n=30) and only 3 studies.
