Vitamin C: Best known as an antioxidant, but it also works with various enzymes in the body. In relation to Growth Hormone (GH), Vitamin C acts as a co-factor in the activity of an enzyme called Peptidylglycine Alpha-Amidating Monooxygenase, or PAM, which activates various neuropeptides, or brain proteins. PAM exists in large amounts in both the hypothalamus of the brain, where Growth-Hormone-Releasing Hormone (GHRH) is produced, and the pituitary gland, where GH is produced. The thought is that vitamin C, through its actions on PAM, activates Growth-Hormone-Releasing Hormone from the hypothalamus, which then triggers the release of GH from the pituitary gland.
Vitamin C is a water soluble vitamin commonly found in a variety of fruit and vegetables. It is essential to maintain the health the of skin, cartilage, teeth, bone, and blood vessels and is also an antioxidant, helping to protect the cells of the body from free radical damage.
