The study is a good review on the many good properties of glycine, but specifically its use for autoimmune and chronic inflammatory conditions. One of the new things that I learned from this study is that glycine acts as a calcium blocking agent, so it should be good for a variety of conditions associated with calcification such as CVD, diabetes, various conditions with fibrosis, etc. This also explains why gelatin helps many people with conditions Chron's, IBS / IBD, NAFLD, and so on.

"...As a consequence, agonist-induced opening of L-type voltage-dependent calcium channels and the resulting increases in intracellular calcium ions are suppressed, which may account for the immunomodulatory and antiinflammatory effects of glycine. Lastly, glycine blocks the opening of relatively non-specific pores in the plasma membrane that occurs as the penultimate event leading to necrotic cell death."
