Is proline lactobacillus (lactic acid bacteria) same thing as l-proline amino acid?

No; some probiotics – notably Lactobacillus casei – make enzymes that help digest casein peptides made primarily of proline called ‘proline-specific proteases’. Proline is also a major constituent of collagen, as well as of casein. The enzymes help to break down casein polypeptides into free form or (minimally) peptide-bound l-proline chains containing only 2-3 proline molecules, which can pass our gut barrier as properly digested proteins. So it refers to the probiotic organisms producing casein-digestive enzymes to help digest the casein in milk products, which is typically the most difficult and time-consuming milk protein to digest.

An Essential Amino Acid

I bought a vegan collagen, and it was missing l-choline and l-proline, so I added these to complete the formula for hair, skin, nails, and joints. So far, so good. As a senior, this is important to me.

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!
