Rated 3 out of 5 by from Difference with the 500mg size Unfortunately this 1000mg size contains magnesium stearate whereas the 500mg size does not, according to the declared ingredient list. I'll be going for the 500mg size from now on.

Rated 3 out of 5 by from Need versus price I don't believe that there is a true amount of any type of collagen for the human body. I felt that the amount of supplement & price that was suggested, did not measure up for expected results.
