How the ingredients work together

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

33 of 7 nutrients at a meaningful dose (≥20% Daily Value) — the other 4 are present at low levels.
B12 + FolateWork together

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

Magnesium + B6Work together

B6 supports cellular magnesium uptake; the combination is better studied than magnesium alone for some uses.
