Knox gelatin vs collagen2/12/2024 ![]() ![]() ![]() Glycine is a tiny amino with a talent for structuring very tightly packed chains. Glycine contributes one-third of the total aminos. To understand why these nutrients might be so critical to joint health, I consulted several textbooks and learned that hyaline cartilage, the most common type in the human body, derives its strength from a dense, criss-crossing, ropey network of collagenous fibers, and its resilience from the gel-like matrix into which these fibers are embedded.Īccording to a textbook on bone disorders, 2 proline and glycine play starring roles in the collagenous fibers built from gigantic proteins containing some 1,000 amino acids each. The notion that the body can create proline and glycine is, of course, the reason that neither amino is considered “essential.” The ability to manufacture them easily and abundantly as needed, however, is probably true only of people enjoying radiant good health.Common sense suggests that the millions of Americans suffering from stiff joints, skin diseases and other collagen, connective tissue and cartilage disorders might be suffering serious shortfalls of proline, glycine and other needed nutrients. So it was not surprising in 1997 when the editors of the Tufts University Health & Nutrition Letter advised consumers not to buy Nutrajoint or similar supplements because the idea that gelatin can contribute to the building of strong cartilage and bones “is a theory that has yet to be investigated.” As for the theory itself, they sniffed that it “sounds tidy–rather along the lines of ‘you are what you eat.’” In conclusion, they stated that even if Nutrajoint worked as claimed, it would be totally unnecessary because “the body can manufacture its own proline and glycine as needed and therefore suffers no shortfall.” 1 These early studies, however, have fallen off the radar screen of Knox as well as that of nearly everyone else. In fact, the evidence goes back more than a century, and not only established gelatin’s value to cartilage and bones but also to the skin, digestive tract, immune system, heart and muscles. This supplement contains gelatin, vitamin C and calcium, and advertisements touted “recent scientific studies” proving that gelatin can contribute to the building of strong cartilage and bones. Several years ago Knox Gelatin introduced a new product named Nutrajoint with great fanfare. Nourishing Traditional Diets with Sally Fallon Morell.
