Nature's Pure Blend Nitric Oxide Supplement L-Arginine - Blood Pressure Support Capsule - 1500MG - Nitric Oxide Booster - Amino Energy - Preworkout for Men, Muscle Growth

WHAT IS NITRIC OXIDE FLOW? Nitric Oxide is naturally produced by your body. Almost every single cell in your body produces Nitric Oxide. Nitric Oxide is a vasodilator, which means it dilates and relaxes the inner muscles of blood vessels. This causes your blood vessels to widen and relax.
WHY IS IT IMPORTANT TO TAKE NITRIC OXIDE FLOW? As we age our bodies lose the ability to produce nitric oxide naturally. By the time we reach the age of 40 we produce about 50% less nitric oxide that we did at the age of 20. At the age of 50 we are producing about 35% of nitric oxide, which can cause calcium build up and stiffening of the arteries. Finally at the age of 60 plus we can be down to only 15% of natural nitric oxide production.
WHAT IS L-ARGININE AND L-CITRULLINE? L- Arginine converts into Nitric Oxide in the Body, and L- Citrulline is converted into L-Arginine which is then converted into Nitric Oxide. L-Arginine is more of a fast acting boost of nitric oxide production as L-Citrulline is converted when the body needs to use it. So with our 2:1 ratio not only do you get the instant effect, but you also keep your nitric oxide levels up as your body will use the L-Citrulline as needed to convert into Nitric Oxide.
WHY US? We do extensive research with all of our products to insure that our products have no artificial ingredients, chemicals, or preservatives. That's why our Nitric Oxide Booster, Nitric Oxide Pills for men is the best.
