L-Proline is an amino acid that is essential for the synthesis of collagen, the most abundant protein in mammals. Collagen is the main structural protein that constitutes all human connective tissues, including skin, tendons, ligaments, joints, bone, and vasculature (veins and arteries). L-Proline therefore provides building blocks that help to stabilized and strengthen the structural components of the body. Although proline can be made in the body, low protein and vegetarian diets may not provide optimal support for the production of collagen. Now L-Proline Vcaps are 100% vegetarian.

iHerb Customer Reviews

OK Product

Posted by MarieMR on Aug 04, 2016

As the powder form was not available I brought these. They do added filler which I do not like. However I opened capsules and put powder into my smoothies and does not overwhelm the taste of my smoothies. L-Proline mixed in water is slightly bitter tasting on its own but not over powering. Proline is good for tissues and muscles for making the fibers more flexible and strong. I am very happy with iHerb's wonderful range of products, they have top customer service and the DHL delivery service they provide is just fantastic!! Thank you.

I really like this product and share it with other people. I'm personally using it to help heal my leaky gut.

This made all the difference in my healing.

Posted by Reviewer2973820 on Jul 04, 2016

I learned about L-Proline while trying to find something to speed up the healing of my back. I take this and Natural Factors BioSil ch-OSA Advanced Collagen Generator and Proline together in the morning and it has made all the difference. I can literally feel my back getting better after a year of very slow healing. I also take the other BioSil products with Now Foods Calcium Magnesium at night and am thankful to the person that wrote the Proline/BioSil review everyday.

Good for elemental diet.

Posted by 5602636760187637595 on May 20, 2016

I used this product in combination with several other amino acids for a homemade elemental diet (for SIBO and other digestive issues) and it worked well. Could take on empty stomach, no problem. L-proline is very good for tightening junctions in leaky gut, along with l-glutamine. Good price, great shipping. Got my packages in 2 weeks all the way to Norway.
