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. **Q: what exactly are the ingredients on the label other than Proline?** A: Hello, Amazon:This email is in response to Ticket #220436.Other Ingredients: Cellulose (capsule), Stearic Acid (vegetable source) and Silica.Contains no: sugar, salt, starch, yeast, wheat, gluten, corn, soy, milk, egg, shellfish or preservatives.Have a Great Day!Spread The Wellness!Gianni MHappy Wellness AmbassadorLuckyVitamin.com **Q: What is the country of origin?** A: USA or more precisely, Bloomingdales, Illinois **Q: is this a weight loss supplement** A: I would not classify this as a weight management product. ## Frequently Bought Together - NOW Foods Supplements, L-Proline 500 mg, Collagen Production*, Structural Support*, 120 Veg Capsules - NOW Foods Supplements, (L-Lysine Hydrochloride) 1,000 mg, Double Strength, Amino Acid, 100 Tablets - NOW Foods Supplements, Tri-Amino with L-Arginine, L-Ornithine, L-Lysine, Supports Protein Metabolism*, 120 Capsules --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/4176446-supplements-l-proline-500-mg-collagen-production-120-veg-caps](https://www.desertcart.us/products/4176446-supplements-l-proline-500-mg-collagen-production-120-veg-caps) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-29*
