NO supplements or not??
“Explosive workouts.” “Extreme pumps.” “Enhanced endurance.” These are just some of the marketing claims used to promote nitric oxide (NO) supplements. Interestingly though, NO supplements don’t actually contain any nitric oxide, which is a gas. Instead, these types of supplements usually contain amino acids plus various other ingredients. So will these supplements fulfill their promises of improving your performance or are they just “full of hot air”? Nitric oxide (NO) is a gas. Produced naturally in the body, it relaxes blood vessels and increases blood flow. Based on this, some pre-workout supplements are marketed as “NO” or “nitric oxide” supplements and claim to improve strength, performance, muscle size, and endurance. However, these supplements don’t contain any nitric oxide. Instead, NO supplements contain amino acids, primarily L-arginine and L-citrulline, which the body uses to make nitric oxide. The theory behind NO supplements is that these amino acids increase your body’s production of nitric oxide, which then improves blood flow and the transport of oxygen and nutrients to the muscles to enhance performance. However, in terms of their actual effectiveness, results of studies are mixed. At this time, there is no clear scientific evidence that NO supplements increase muscle mass or improve physical performance. Because the ingredients in NO supplements can vary greatly, it isn’t possible to make a statement about their overall safety. Some contain stimulants or other potentially problematic ingredients (unrelated to the purported NO effect) that can increase the risk of adverse reactions. For ratings of the safety and effectiveness of individual NO products, please visit the Natural Medicines Comprehensive Database (NMCD). http://hprc-online.org/dietary-supplements/opss/operation-supplement-safety-OPSS/opss-frequently-asked-questions-faqs-1/nitric-oxide-supplements
