Vitboost supplement

L-arginine and L-citrulline are two amino acids that have potential therapeutic uses. A relationship between the two exists in that L-citrulline is converted into L-arginine once inside the body. Therefore, L-citrulline is sometimes supplemented to increase levels of L-arginine. Being a precursor to L-arginine, L-citrulline can potentially be used as a treatment for the same conditions as L-arginine, in addition to being used as a sports supplement. Arginine Background L-arginine works primarily through increasing nitric oxide levels in the blood. Higher nitric oxide levels relax and dilate blood vessels, thus increasing blood circulation to various organs, including the heart, skin and sexual organs. L-arginine is a conditionally essential amino acid, meaning the body can normally manufacture a sufficient supply, although times of stress or injury can deplete the body's supply. Many foods, including meat, dairy products, fish, poultry, nuts, and chocolate, are good sources
