How the ingredients work together

Known interactions from published nutrition research — separate from the evidence grade.

Iron + Vitamin CWork together

Vitamin C markedly improves non-heme iron absorption by reducing it to its more absorbable form.

B12 + FolateWork together

B12 and folate work in the same methylation cycle; supplementing both supports homocysteine metabolism better than either alone.

Vitamin C + Vitamin EWork together

Vitamin C regenerates oxidized vitamin E, recycling its antioxidant capacity.

Iron vs ZincCompete

Iron and zinc compete for absorption when taken together at higher doses on an empty stomach.
