I can offer a couple things. Iron needs to be taken with Vit C for best absorption.

I think, calcium needs to be taken away from iron.

D3 and K2 at the same time.

I take most of what you take and spread them out thru the day... Some things I take some higher doses. So I spread them out.

I see you are missing OPC's which are pycnogenol, grape seed extract and resveratrol....I take the first 2 going on 20 yrs. I'm in good health overall and a grandma...a lot of joint issues from a long life.
