It may not be of much use to you as I'm in the UK and use a brand produced here, but, as a comparison, I take two tablespoons daily of Hunter & Gather's Collagen Peptides Bovine Protein Powder which contains 13,000mg of collagen per serving.
They also do a Marine Collagen Peptides Protein Powder with 10,000mg of collagen per serving, but I much prefer the taste and higher collagen content of the bovine.
