I give her now to MSM, as I read, this promotes absorption.
I wonder now, to take the collagen itself. It is not the cheapest on the market,
but since it is made in Germany, it gets a "pre-bonus". Some dietary supplements from abroad are not completely unloaded (except the really good products from the United States to refer, for example, on energy-cosmetic, or other good companies).
Now I try only times the collagen hydrolyzate of manako.
I will continue to report.
