Creatine monohydrate has the strongest rating (DEX Score 88, very high across all dimensions), with consistent benefits for short-burst strength and power in sports such as rowing, jumping, and soccer. Caffeine (DEX Score 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 (DEX Score 76; high effect size, high evidence, medium trust) supports muscle strength and size when combined with training.

Beta-Alanine (DEX Score 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 (DEX Score 68; medium effect size, very high evidence, medium trust) shows mixed aerobic benefits but may reduce fatigue and soreness at higher pre-exercise doses.
