Muscle pump is caused by increased blood flow into the muscle being exercise, this is important as it helps deliver nutrients that are essential for muscle growth. Sometimes getting a pump can be difficult, therefore the use of products that initiate blood flow through the enhanced production of nitric oxide, an important cell signaller that signals the body to increase blood flow into the muscle being exercised, can be of benefit. Nitric oxide is a molecule in the body that increases blood flow into the muscle being exercised. This increase in blood flow is important as it helps deliver nutrients to the muscle, assisting in muscle recovery and growth. Many of our products contain pre-cursors to nitric oxide, as direct supplementation is not an effective way to deliver it into the body.
