How the ingredients work together
Known interactions from published nutrition research — separate from the evidence grade.
22 of 8 nutrients at a meaningful dose (≥20% Daily Value) — the other 6 are present at low levels.
Magnesium + B6Work together
B6 supports cellular magnesium uptake; the combination is better studied than magnesium alone for some uses.
Calcium vs ZincCompete
High-dose calcium can reduce zinc absorption — the two compete for uptake pathways.
