Healing my Rheumatoid Arthritis

I take this in conjunction with High dose VitaminC, Lysine and Niacinamide as per Pauling/Rath Protocol to reverse heart disease but I take it all to generate healthy collagen in connective tissue battling my RA. It works well for me.

Ex Disgruntled buyer

I had a rather rough experience with buying l-proline recently. I left a rather poor review. To say how surprised I was then I got a call from an executive regarding that review telling me they would ship me to proline and they did it for free shocked me. I've never had a company called me when I was just gruntled you have a loyal customer in me, no matter what. To say the least this company rocks. Thank you thank you thank you for your outstanding integrity


Hello Vickie, Thank you for taking my call. I'm glad I was able to help you. You Rock!

Disgruntled buyer

I had been waiting for the proline to come in in the larger size for quite some time as I take it for my heart. Excitedly I saw it arrived on the website, ordered it, and awaited its arrival. I then got an email stating that they weren't able to deliver it I called the company and they didn't know when it would be in as they were just testing it I got no satisfaction from calling them and no help either


Hello Vickie, Thank you for taking my call today. I'm glad I was able to help and listen to your concerns.
