He said that not all collagen are equal. It is about the size of the particle collagen that matters. It is measured in daltons (size).This is 3000 daltons. Most collagen particle size is many times larger than 3000 daltons, and most are like 10,000 daltons. The smaller the size, the more absorption you get. As far as clumping, there is no added stuff it in it to prevent that, which is good. I stir it up in my fresh grapefruit juice and get very little clumping and anyway, it just gets swallowed. It has no taste. I trust the brilliance of my Chiropractor. If you go to their website, thedoctorwithin.com and buy 6, you get it for $35. each. Since one bag lasts about a month, that gives my six months worth. This stuff really helps me, as I am 75 years old.

Best collagen on the market! Our Chiropractic office sells this and we personally use it. Regarding “clumping” issue: It is not meant to be stirred, but rather put in shaker bottle or blend with a smoothie high in Vit C. The results are phenomenal.

This produce is of the best quality and would recommend this vendor to anyone who is using collagen.
