I have been taking type II as well, for the past few months.

What is the difference between I, II & III
Also I went to vitamin shoppe today and they had collagen in powdered form (its said to contain I, II & III) but my problem is that it is so expensive. The 15 serving size cost $50 and the 30 serving size cost $80.
Does it generally cost that much?
