Nitric Boost Ultra Reviews And Complaints (INVESTIGATED) 2025
“NITRIC OXIDE IS a gas and free radical that’s recognized to play a role in several physiological systems,” says Alex Rothstein, M.S., an instructor in the exercise science program at the New York Institute of Technology. It’s synthesized from L-arginine, an essential amino acid.
Nitric oxide acts as a vasodilator, which means it helps open blood vessels. As a result, many people take the precursor L-arginine for issues like erectile dysfunction and to improve heart health.
Nitric oxide’s role in vasodilation is also important for regulating blood pressure, says William Workman, M.D., an orthopedic surgeon and sports medicine expert at DISC Sports & Spine Center in Walnut Creek, California.
Many small blood vessels and capillaries sit dormant until you get your heart rate up during exercise, and nitric oxide enables blood to flow to these areas to allow your muscles to work, hence its reputation as a substance that can help your fitness performance.
Other important functions of nitric oxide are its roles in neurotransmission, hormone signaling, and the relaxation of blood vessels, explains Marco Anzures, M.S., C.S.C.S., owner of the coaching platform Coach You Better and an exercise science instructor at San Diego City College
