Supplements for Fatigue And Physical Performance

What the Research Shows

Research indicates that certain supplements can influence energy levels and physical output, though results vary by substance. Ginseng is supported by strong evidence for reducing fatigue and improving physical performance. Other common supplements, such as creatine or caffeine, often show moderate to strong evidence for enhancing strength and endurance, but their effects can depend heavily on the individual's baseline fitness and the type of activity performed. However, much of the available data is limited by small sample sizes or short study durations. Evidence for many botanical extracts and 'energy-boosting' vitamins is often weak or conflicting, with some studies showing benefit while others show no difference compared to a placebo. In many cases, there is insufficient evidence to conclude that a supplement provides a meaningful advantage for the general population. These limitations highlight the gap between marketing claims and clinical proof.
