zinc absorbtion

[a55]

I read somewhere that your body only absorbs about 30% of the ammount you intake. Is that true with all zinc supplements? If that is true, If i take 100mg of zinc i only absorb 30mg. LMK

Don't go thinking you should be taking 3.33x the recommended dosages

It could have been referencing a multi with zinc and calcium, since calcium can inhibit zinc uptake. Maybe that's what they meant? I also know in other minerals and vitamins there are sources which are synthetic and not very bio-available. Maybe there is a form of zinc that falls under that category but I'm not sure.

I'm not convinced that this is the case in light of the bodybuilding diet and subsequent micronutrient intake, but it's just intuition:
