UC-II vs Glucosamine & Chondroitin
Compare newer undenatured type II collagen products with the traditional glucosamine/chondroitin category.
Quick take
Undenatured type II collagen is used at low milligram doses, while glucosamine and chondroitin products usually use much larger amounts.
What matters most
Those dose differences reflect different materials and proposed mechanisms; they do not mean that the lower-dose product is inherently more potent.
