Supplements for Endurance Exercise Capacity

What the Research Shows

Research indicates that a small number of supplements provide measurable benefits for endurance capacity, while many popular options lack robust support. Creatine monohydrate and beta-alanine show strong evidence for improving high-intensity endurance and buffering capacity. Caffeine is supported by strong evidence for enhancing overall endurance performance and reducing perceived exertion. Nitrate-rich supplements, such as beetroot juice, show moderate evidence for improving efficiency and time-to-exhaustion. Conversely, many supplements have insufficient or conflicting data. Quercetin, for example, has weak evidence regarding its ability to improve endurance. Other common antioxidants and herbal extracts often show insufficient evidence to justify their use for performance gains. Current research is limited by small sample sizes and varying fitness levels among participants, meaning results may not apply to everyone.
