L-Proline/Lysine Amino Acids with Vitamin C, Magnesium, Grape Seed, &
Hawthorn Berry Extract
120 tablets

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 promote optimal l-proline production.  L-Lysine and l-proline amino acids are the precursors of hydroxy-lysine (HL), and hydroxy-proline (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.

As recommended by Matthias Rath, MD, Vitamin C (at least 3 grams/day in divided doses), L-lysine (at least 500 mg/day in divided doses), L-proline (at least 1 gram/day in divided doses), and green tea extract known as Epigallocatechin Gallate (EGCG) (at least 600 mg green tea/day in divided doses) work together synergistically.  In 1992, Dr. Rath published research suggesting the use of amino acid l-lysine as a natural inhibitor of plasmin and other enzymes (matrix metalloproteinases) involved in collagen digestion.  Recently, Dr. Rath and his team of researchers at the Matthias Rath Research Institute in Cellular Medicine, Santa Clara, CA have identified a specific combination of nutrients that can inhibit the activity of collagen dissolving enzymes.

Vitamin C has an ability to increase collagen production.  Vitamin C is required for the hydroxylation of l-proline, which in turn is required for collagen production.  Vitamin C has the ability to inhibit enzymes that degrade or break down the extracellular matrix.  Finally, vitamin C helps to create the collagen-rich bone matrix.  One component of collagen (connective tissue) is hydroxyproline, an amino acid formed when proline becomes hydroxylated, a step that requires vitamin C.  That is why bones break so easily and tissues are so weak in people with scurvy, which is the overt form of vitamin C deficiency.  Although scurvy is rare, scientists like Linus Pauling and Irwin Stone long ago pointed out that most of us exist in a state of chronic subclinical scurvy due to near-universal insufficiency of vitamin C in our diet. In addition, L-arginine is metabolized to L-proline, a major constituent of the collagen that makes up fibrotic extracellular matrix.

L-Proline can be made in the body, but low protein/vegetarian diets may not always promote optimal production.  L-Proline is an essential component of arterial linings.  It is the precursor of hyroxyproline, one of the two constituents of collagen, an essential component of arterial linings.  Long chains of molecularly bonded individual amino acids form protein.  The body must first break these molecular (peptide) bonds for amino acid absorption to take place.  This form of l-proline is already in its simplest form (no peptide bonds) and can be readily absorbed into the bloodstream.

In addition, hundreds of collective studies show carnitine (at least 1.5 grams/day in divided doses), magnesium (at least 300 mg/day in divided doses), and coenzyme Q10 (at least 100 mg/day in divided doses) to be very valuable tonics for the circulatory system.  Deficiencies of these essential nutrients impair the pumping performance of the heart which can result in shortness of breath, edema, and fatigue according to Dr. Rath and colleagues.
