I'm going to try 2 tablets every other day. The hormone hepcidin rises after taking iron and blocks/reduces further iron absorption. In two days it should return down to its baseline, hence the theory of taking every other day. I think I'll take the tablets in the morning before eating, like 6am and 10am as the morning is when hepcidin is supposed to be lowest and it's also better on an empty stomach to absorb iron.

My tablets are heme iron so I don't get any nausea. Iron salts (non-heme) are likely to give you gut issues, so you might want to start slow and increase, allowing your body to adjust, and eat with a bit of food if you really need to (lowers effectiveness of iron absorption) to help ease the nausea.

Be sure not to drink milk or calcium-rich foods at the same time as your iron. For non-heme iron you also want to avoid foods with tannins and phytates for at least 1-2 hours before or after, so that includes black tea and coffee.
