Question:
Are there any difference between the affect of collagen mg1000 and 400mg?
I'm considering taking it but don't know which? How much is safe to take?
Answers: what do you expect from taking it? What are you going to take it for? I don't know the exact amounts but take less of the 1000 mg. Take about half as much as you would using a weaker 400mg dose.
