Source Naturals Proline & Lysine 550 mg 120 Tab

Proline & lysine l-lysine is one of 9 essential amino acids that cannot be made in the body. It is the basic raw material for carnitine synthesis. L-proline can be made in the body, but low-protein/vegetarian diets may not always promote optimal l-proline production. L-lysine and l-proline amino acids are the precursors of hydroxylysine (hl), and hydroxyproline (hp), two constituents of collagen. Collagen is an essential component of arterial linings. Vitamin c, a strong antioxidant, is also essential for the production of collagen. Hawthorn berry and grape seed extract are potent natural antioxidants due to their high levels of proanthocyanidin. These proanthocyanidin-esters are excellent free radical scavengers. microcrystalline cellulose, sorbitol, stearic acid, silica, and magnesium stearate.ingredients: calories -25 total carbohydrate -2 gvitamin c (as calcium ascorbate and ascorbic acid) -1,000 mgcalcium (as calcium ascorbate) -66 mgmagnesium (as magnesium citrate) -46 mgl-l
