How the ingredients work together
Known interactions from published nutrition research — separate from the evidence grade.
Vitamin D is required for efficient intestinal calcium absorption — the classic bone-health pairing.
Magnesium is a cofactor for the enzymes that activate vitamin D; low magnesium blunts vitamin D response.
Vitamin C markedly improves non-heme iron absorption by reducing it to its more absorbable form.
B12 and folate work in the same methylation cycle; supplementing both supports homocysteine metabolism better than either alone.
Calcium inhibits iron absorption when taken together. If you take this for the iron, consider spacing it from calcium-rich meals or supplements.
