I guess there are 5 types the human body needs most. they just call them type 1-5. They are needed in that order with type 1 being about 90% of what you need. each one doing different things. type 3 is from beef. So when you see all the hype about bone broth and see it all bein sold from cow... its sort of a scam, a little. because that type of collagen is needed less than type 1 and 2. Anyway, fish, quail, and even goat are type 1 :)
