Collagen Production L-Proline is an amino acid that is necessary for collagen production.* Collagen is the main structural protein that constitutes all human connective tissues, including skin, tendons, ligaments, joints, bone, and blood vessels (veins and arteries).* L-Proline is therefore a building block that helps to stabilize and strengthen the structural components of the body.* Although Proline is naturally produced in the body, in specific high-demand situations, a regular diet may not be sufficient to respond to the body’s need for Proline.*

Trusted Brand; Gelatin Caps an Easy Way to Supplement Amino Acids
L-Proline is an amino acid that can help build/repair collagen. So it’s good for skin, among other things you can Google.Coupled with Vitamin C and L-Lysine (another amino acid), L-Proline is part of the “Pauling Protocol” (as in Linus Pauling) for improving cardiovascular health. Anyone interested in knowing more about the Pauling Protocol will find some very valuable information online, just by Googling “Pauling Therapy.”I have friends who swear by l-proline for improving joint health.NOW brands offers good quality supplements at an affordable price & this one’s no exception; I’m glad to find an amino acid in a gelatin capsule, rather than in compressed tablets. I’ve been using this for about 6 weeks and have had no adverse reactions. Just keep in mind that if you’re using this for skin or joint health, it will most likely take a few months to notice significant improvement. Supplements are a long-range solution, not a short-term one, so be patient. I like this l-proline & will continue to order via Subscribe & Save. Recommended!

A must have if you take collagen
This is a must have if you take collagen. Your body does not absorb collagen without this important amino acid. I have tried several brands of proline but this one has improved my skins look and feel when taken with collagen

Great product
I find it much better to use capsules than the pure powder. The powder gets clogged up in short order.Now brand is the brand I rely on for many products.

My view point…
I never write reviews on vitamins, supplements or herbs until at least a month. It takes each of us a different time frame to notice the affects since we all have a difference in built, metabolic rate and more. For me I have noticed a difference in my collagen after 3.5 weeks. Much improved in my joints. Moderate in tendons and skin. But my experience is mine for the vast list of medical conditions I struggle with daily. I like NOW products as an option and and find more of what I look for or need as their product line is vast. Being new on relying on vitamins and more I do try other manufacturers since the additives are different as well as the % you receive in taking them. While each manufacturer estimates how much you can expec in your system it is that truly your own individual system that dictates that. I will have no problems in reordering this again.

Very large and hard (or impossible) to swallow.
These are so big that they are hard to swallow. My husband can swallow them barely; I cannot swallow them. I may put them in water and dissolve them that.
