Type, Size & Quantity

Collagen is much like glue for cells in that it is able to help give shape and support to blood vessels, organs, bones, the liver, and kidneys. It also helps keep teeth securely tethered to the gums and assists in the maintenance and repair of blood vessels, bone fractures, and bruises. Proline also works in tandem with Vitamin C and Lysine to help maintain the integrity of Collagen.

Though Proline is synthesized by the body, often the amount that is actually produced is not enough. It is mainly found through dietary means in animal products. Extra sources are so few and far between that a vegetarian may need to supplement in order to get the correct amount. Proline is also used to some extent in energy production which is why it is found in so many sports drinks.

Health Benefits Provided by L-Proline

L-Proline is needed to form Collagen, and Collagen is one of the most important building blocks that make up the visible human body on the surface of and beneath the skin. Collagen is a connective tissue that keeps up the health of blood vessels, bones, organs, and teeth. It is an absolute necessity to maintain all of the elements that keep collagen working strong. Proline may be reduced after exercise so it might be best to recharge on Proline after exercise.

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

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.
