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.

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.

It is difficult to find a vegetarian collagen. I like that this product is vegetarian. My knees are feeling better since I started taking it.

No he notado nada extraordinario así de repente, pero desde que tomo esto junto con Q10, y ácido hialurónico con MSM, desde luego mi artrosis ha mejorado espectacularmente. Mis manos no se han deformado más y los dolores, de momento, han desaparecido. No puedo saber cuál de los suplementos ha hecho el milagro, ¡supongo que fue el conjunto de todos ellos¡
