Introducing our first economical, high-quality L-proline supplement.

Rated 4.5 out of 5 by 11 reviewers.
Rated 4 out of 5 by swanson's L-Proline I take this in the morning by itself, and other amino's throughout the day. So far, after a few weeks, I haven't seen any results, but it could take awhile to get into the system. So, we'll see. February 21, 2016
Rated 4 out of 5 by PRO-TEAM PLAYER I use the Amino Acid L-Proline as part of my successful joint program, which includes a number of nutritional supplements I buy from Swanson Health Products, such as NOW Double Strength Hyaluronic Acid 100 mg., Swanson's Gluc., Chon., MSM liquid combination, Boswelia, Green Lipped Mussel, High Ig Colostrum, and of course Flaxseed Oil and Supreme C Complex. Swanson's own material refers to L-Proline as "amino acid nutrition for healthy connective tissue." Since the body is a complex biochemical factory, no one element is the complete answer. It's all about the synergistic teamwork of harmonious factors. It isn't possible for me to assign a numerical or percentage value to each nutritional factor member of my team. But just like any successful football or baseball team, each player makes a significant contribution. Personally, I take 4 capsules daily. Works for me. February 19, 2014
Rated 4 out of 5 by Good product So far, so good with this product. This is part of a routine I started for adrenal support and, as part of the regimen, this product is working quite well. November 4, 2013
Rated 5 out of 5 by It helps improve my nails I realized some time ago that I needed L-Proline to grow better, stronger nails. Of course I checked out Swanson, who generally has the best products for the best price and my nails are now stronger and longer. September 26, 2013

Rated 4 out of 5 by excellent and convenient very helpful with vitamin C and lysine for heart. convenient to take and to order. April 9, 2012
Rated 5 out of 5 by Anti-aging starts within I'm going to include Glutathione in this review because the combination of L-Proline & Glutathione has improved my skintone. I'm 55, figure that if I eat right, exercise, etc. at least 80% of the time, I can make up for infractions 20% of the time. Swanson has been helping me stay healthy & youthful for some time. Anyone can make claims, but unless you try something & stick with it for at least a season, how will you know? My body uses up nutrients very quickly, & supplements prevent the daily wear & tear that ages the body inside & out. Both L-Proline & Glutathione have helped me maintain elasticity & adjust to environmental exposure. I work outdoors, use SPF's, drink water, do the do's... but these two products keep my skin looking & feeling smoother & youthful. Combined with regular stretching, exercise & smart topical products, there is every reason to age gracefully. August 16, 2009
Rated 5 out of 5 by Proline is a part of my waking up in the morning I have taken Proline over the last three or four years and have believed it to help me through each new day. I feel better after taking it and Swanson brand offers a Proline I can count on. As being one of my three aminos that I have by my bedside, I take it with water every morning upon greeting each new day. This is my daily amino "coffee" before my real coffee is served! Swanson's Proline is priced far more reasonably than other brands and delivers what my body needs. July 23, 2009
