14 Groundbreaking Supplements That Mimic the Benefits of Exercise

4. L-Citrulline: Boosting Nitric Oxide Production

L-Citrulline, an amino acid found in watermelon and other foods, is a precursor to L-arginine, which in turn increases nitric oxide production in the body. Nitric oxide is a vasodilator, meaning it helps widen blood vessels and improve blood flow. This process is akin to the effects of aerobic exercise, which enhances circulation and cardiovascular health. L-Citrulline supplementation has been shown to improve exercise performance, reduce muscle fatigue, and enhance recovery. By increasing nitric oxide levels, L-Citrulline supports cardiovascular health and muscle function, providing benefits similar to those gained from regular physical activity. Its role in enhancing blood flow also supports nutrient delivery to muscles, further mimicking the effects of exercise.
