Athletic performance

Supplements studied for athletic performance.

Overview

SupplementDEX indexes 49 supplements for athletic performance across 461 studies—the largest evidence base in this batch.

Creatine monohydrate has the strongest rating (WA 88, very high across all dimensions), with consistent benefits for short-burst strength and power in sports such as rowing, jumping, and soccer. Caffeine (WA 88; high effect size, very high evidence, very high trust) reliably improves performance, endurance, and strength, with effects varying by body weight and habitual intake. Whey Protein (WA 76; high effect size, high evidence, medium trust) supports muscle strength and size when combined with training.

Beta-Alanine (WA 68; medium effect size, very high evidence, medium trust) may improve high-intensity endurance lasting one to four minutes after weeks of daily use. L-Citrulline (WA 68; medium effect size, very high evidence, medium trust) shows mixed aerobic benefits but may reduce fatigue and soreness at higher pre-exercise doses.
