Manganese Competes Directly With Iron For Absorption

This study showed that manganese directly competes with Iron absorption and is dose dependent. The way I understand this seems to mean if 2mg of manganese is competing with 3mg of iron, the manganese will allow only 1mg of iron to be absorbed. Zinc, on the other hand, only tends to reduce the tendency of iron absorption but doesn't inhibit like manganese. So if manganese content is larger, no iron will be absorbed. A high manganese food is maple syrup. Which may explain why I sneak gulps of it when no one is looking.

I don think manganese supplements are the same as whole food sources of manganese, and would hesitate to see anyone take it in supplement form, as manganese is also a neurotoxin, despite being an essential element.

Manganese for me means instant anxiety relief.

Wasn't there something about inhibiting dopamine reuptake?

I know it can combat many of iron's deleterious effects (perhaps while bringing some of its own).

Edit: Hehe, right there in the similar threads. :P

go to amazon or other supplement websites, type in manganese in their search bar, and read the comments/reviews of the manganese products... you might be surprised

Hi @moringa I did read reviews of 6 products on Amazon. Why would I be surprised? That people got good results from manganese supplementation? Thank you for clarifying and helping me understand.

Important information on the safety of manganese:


disclaimer: the above video is funny but not actually important

edit: bah can I not post a youtube video with a timestamp? Whatever, at 5:20 **** Gregory starts foaming at the mouth about the conspiracy of manganese poisoning.

Carry on everyone.
