Among the supplements and ergogenic aids showing the most promise for improving aerobic exercise performance are caffeine, supplemental carbohydrates, creatine (creatine monohydrate), nitrate (e.g., beetroot juice), beta-alanine, and sodium bicarbonate.[1] Other supplements with less robust evidence to support their efficacy are citrulline, glycerol, quercetin, taurine, arginine, and medium-chain triglycerides (MCTs).[2]
Have any supplements been studied for aerobic exercise performance?

Several supplements, including caffeine, supplemental carbohydrates, creatine, nitrate, beta-alanine, and sodium bicarbonate, have shown promise for enhancing aerobic exercise performance. Other supplements like citrulline, glycerol, quercetin, taurine, arginine, and medium-chain triglycerides have less robust evidence supporting their effectiveness.
