Non-glucosamine supplements often contain collagen I and collagen III, which are most abundant in the skin. Collagen supplements come in different dosages. When used as a beauty supplement, collagen should be limited to about five or six grams daily, while more may be required to address joint or bone pain. Arthritis patients may take up to 10 grams of collagen daily. Collagen is water soluble, so excess amounts are quickly flushed from the body.
