Take this product with proline, 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!

these work well to calm my nerves, and and calm my upset stomach. They got rid of my acid reflux. The problem is that when i take them for more than a couple of days, i can not go to the bathroom. That is a big problem for me, since i have had a spinal fusion, with hardware. My spine does not move any when my bowels are full. And that leads to pain. If it were not for the glycine constipating me, i would keep taking them.
