Double reds are brutal. Never again, killed my endurance for months.
Ferrous sulfate is an iron sulfate salt. It's cheap and the go-to for iron supplementation. Avoid calcium and add vitamin C for increased absorption. It's the iron given to most people for anemia and found in cereals, fortified foods.
Iron biglycinate has higher bioavailability and much easier on the stomach.
Does biglycinate raise ferritin just as quickly? I don't get stomach issues on the sulfate but that doesn't mean it might not be doing undesirable things to my gut health.
