nails and connective tissue

Posted by Reviewer2313637 on Oct 23, 2007

This along with Biosil has made a profound change in my body. My ankles always felt spained and my nails were soft and scaly. After taking l-proline along with biosil my ankles have become very strudy and my nails are hard as a rock. I know this stuff works because when I stop using them the old symptoms come back with in a week or so.

Take this product with Glycine and Lysine, and more vitamin C, because then you will be providing substrate for the production of collagen. Do not fall into the big mistake of buying collagen as it is sold. Collagen is a protein, and protein is digested. Because if you buy collagen, your body will digest it! And will use what you thought was collagen in other amino acids. So the best way for you to produce collagen, collagen is not taking. And so, providing the substrate for the building of collagen! Simple! And physiologically consistent!

I have reserved to write a review until I got results back from my blood work. This with L-Lysine and vitamin C has dropped my cholesterol, triglycerides, and my blood pressure as dropped and diabetes has dropped to low 6's after 5 months. The doctor has taken me off some blood pressure pills, lipitor, some diabetic meds. I am getting checked every 3 months and hopefully they will take me off more drugs. These vitamins are good and do work.

Great stuff. I recommend stacking it with hyaluronic acid. Makes a huge difference when weight training and doing cardio. My joints feel great and I feel more balanced when pushing weights. My body just feels good. Now foods makes double strength Hyaluronic acid with l-proline and alpha lipoic acid. I recommend that pill instead of buying the l-proline separate. It makes a huge difference for people who are active. Gotta take it for at least a month..

In combination with Vitamin C and L-Lysine, it is an essential supplement for cardiovascular health and treatment of cholesterol problems. If used properly with the appropriate dosage of other supplements, CVD could be essentially eliminated.

L-proline is an "osmolyte" which helps with protein folding.
