Answer: To date there is one published study related to the efficacy of NO (nitric oxide) boosters via oral ingestion. The major finding of this recent study was that the nitric oxide booster (arginine alpha-ketoglutarate, or AAKG) increased strength and power in resistance-trained men. With recent positive findings and many years of other related data, including relative safety, dotFIT has developed NO7Rage™, an unparalleled supplement that maximizes performance and strength gains for experienced, resistance-trained athletes. The proprietary blend contains, among other specialized ingredients, caffeine, creatine and glucuronolactone. Intravenous arginine supplementation has been shown to increase NO production. However, oral arginine supplementation leads to very little increase in systemic arginine. Interestingly, citrulline, when taken orally, is converted to arginine in the body which leads to significant increases in systemic arginine, enabling the increased production of NO. Increased NO has a vasodilation effect, allowing more nutrients, blood and oxygen to flow into working muscles and waste products and metabolites to be removed, enhancing work capacity, the “PUMP”, and reducing muscular fatigue.
