Vitacost L-Lysine & L-Proline Complex Description

Supports blood vessel flexibility, DNA replication, collagen formation and LDL integrity.*

What is Vitacost L-Lysine & Proline Complex?

Vitacost L-Lysine & L-Proline Complex combines the amino acids L-lysine and L-proline with ascorbic acid, green tea, quercetin and a citrus bioflavonoid complex.

L-lysine is an essential amino acid, meaning it must be obtained through diet. L-lysine is necessary for the formation of collagen, connective and bone tissue.* It’s found in large quantities in muscle tissue. 

L-proline is a nonessential amino acid, meaning it can be manufactured in the body from other amino acids, L-glutamate and L-ornithine. It’s present throughout body tissues, with the highest concentration in collagen.*

Ascorbic acid is an antioxidant that protects low density lipoproteins (LDL) from oxidation, contributes to healthy collagen and connective tissue formation, and promotes arterial flexibility and healthy endothelial function.* These functions work together to offer benefits to the circulatory and cardiovascular systems.* Ascorbic acid also works in conjunction with lysine- and proline-based enzymes in many of the above related functions.*

Green tea, quercetin and the citrus bioflavonoid complex are antioxidants that can play a role in supporting the cardiovascular system, promoting healthy DNA function and duplication, and supporting the integrity of the vascular system.*

How does Vitacost L-Lysine & Proline Complex support heath?

  • Supports cardiovascular health.*
  • Promotes the formation of collagen and connective tissue.*
  • Supports healthy DNA formation.*

Oxidizes/gets damp very fast & too acidic Every couple of years I buy this product because I love the idea of it, but I always end up throwing it out because the capsule contents darken and get damp very quickly. They always spoil, even sealed in the pot. Also, the Vitamin C is in the acidic form, which means one can't take very much of it at all without over-acidifying the body and feeling the effects of that. However this this particular product is intended for mega-dosing, which can only safely be done with non-acidic Vitamin C. If they used Calcium Ascorbate instead, and an airtight pot with proper drying granules, I'd buy a product like this for sure. April 15, 2012
GREAT FORMULA Until I found this product, I had bean searching for something with lysine and proline for quite some time. some doctors believe they act as sort of a teflon coating for the veins. add in the green tea and vitamin c, you've got a pretty cool cocktail for your health. March 14, 2010
Plus a gram of Vitamin C I'm doing the Linus Pauling Protocol and purchased this because it has a gram of Vitamin C with the L-Lysine and L-Proline in the right proportions. Thanks NSI. January 31, 2010

Great combo, but doesn't keep It seems like a very good combination of things together. But even though we used the desiccation packets and stored the item properly, the pills became very dark and mottled looking. Maybe they are still ok to use, but we are afraid to. At the very least the effectiveness would be compromised if some sort of chemical reaction is going on. We considered calling the company, but they generally don't have much in-depth product knowledge. December 20, 2008
