I currently take Marks omegas, vitD and primal flora. I no longer take his multis becuase I wanted one that was a single pill instead of 6 caps. As far as quality... i have no idea. But I am thankful for all Mark has given me for free, so I like to support his brand a lil. Search out user 'Cillakat', she has links in here signature chock full of supplment info.
