L-Proline L-Lysine

  • 275 mg, 120 tablets
  • Item # 02117

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 proanthocyanidinesters are excellent free radical scavengers.
