A trusted source and product, OG
I have been taking this for maybe 4 years now. As a prevention supplement. This is the first time i get it from Amazon. Timely delivery, great product and trusted brand.

It’s impossible to go wrong with this brand, MsLeah
Though I take calcium and vitamin D, I also take lysine to maximize absorption.
