Supplements for Endurance Athletes

What the Research Shows

Research indicates that a few specific supplements provide clear performance benefits for endurance athletes. Creatine monohydrate and beta-alanine have strong evidence for improving high-intensity bursts and buffering muscle acidity, respectively. Caffeine is strongly supported for reducing perceived exertion and improving endurance capacity. Nitrates, often found in beetroot juice, show moderate evidence for improving oxygen efficiency and time-to-exhaustion, though effects vary based on an individual's baseline nitrate levels. Other supplements have more limited or conflicting data. Bicarbonate shows moderate evidence for buffering lactic acid, but its practicality is often limited by gastrointestinal distress. Many popular recovery aids have weak evidence, as their effects are often negligible compared to proper nutrition and sleep. For colostrum, there is currently insufficient evidence to support its use for enhancing endurance performance. Many claims regarding 'superfoods' or specialized endurance blends remain unsupported by rigorous, peer-reviewed clinical trials.
