Iron absorption is best on an empty stomach because other nutrients -- particularly calcium, dairy, phytates in plant foods, coffee, and tea -- can interfere with iron uptake. That said, iron supplements can cause stomach upset for some people. If that's you, take it with a small snack (a banana works well) to reduce discomfort. Avoid taking within 2 hours of calcium-rich foods or beverages.

Baseline Iron+ is designed for daily maintenance and prevention of iron deficiency -- not for treating clinical anemia. The 25mg dose is appropriate for filling normal daily gaps but not high enough to reverse an existing deficiency quickly. If your doctor has diagnosed you with iron deficiency, consult them about prescription or higher-dose over-the-counter options. Once your levels normalize, Baseline Iron+ is well suited for ongoing maintenance.

Multivitamins are convenient, but many of the minerals in a multi -- particularly calcium -- actively interfere with iron absorption. If you're at elevated risk for iron deficiency (endurance athlete, menstruating woman, vegan, or vegetarian), taking iron separately from your other supplements is significantly more effective. Baseline Iron+ is designed as a standalone daily iron formula for exactly this reason.

Iron builds hemoglobin, but healthy red blood cells require all three nutrients -- iron for the oxygen-carrying molecule, B12 and Folate for the cell maturation and DNA synthesis that produces the red blood cells themselves. Deficiency in any of the three creates the same downstream problem: impaired oxygen delivery. Vegans and vegetarians (a group already at higher iron deficiency risk) are often also low in B12 specifically, making the combination particularly effective for that population.

Iron bisglycinate -- the form used in Baseline Iron+ -- is significantly better tolerated than ferrous sulfate, the form found in most drugstore iron supplements. The bisglycinate structure binds iron to the amino acid glycine, which reduces the free iron in your gut that typically causes constipation, nausea, and dark stools. Most people can tolerate Baseline Iron+ without issues. If you do notice stomach upset, taking the capsule with a small snack usually resolves it.
