How the ingredients work together
Known interactions from published nutrition research — separate from the evidence grade.
Vitamin C markedly improves non-heme iron absorption by reducing it to its more absorbable form.
Calcium inhibits iron absorption when taken together. If you take this for the iron, consider spacing it from calcium-rich meals or supplements.
High-dose calcium can reduce zinc absorption — the two compete for uptake pathways.
Iron and zinc compete for absorption when taken together at higher doses on an empty stomach.
