Research evidence score
Weighed against 5 published studies · led by Vitamin D3
Strong pick. Vitamin D3, Calcium and Magnesium (+5 more) have real research behind them.
Based on the ingredients we could read from this scan. A full label may include more — like added sugars, colorings or other ingredients — than we captured here.
How the ingredients work together
Known interactions from published nutrition research — separate from the evidence grade.
66 of 6 nutrients at a meaningful dose (≥20% Daily Value).
✓Zinc balanced with CopperWork together
Long-term zinc supplementation depletes copper; including copper alongside zinc is the textbook-correct formulation.
!Calcium vs ZincCompete
High-dose calcium can reduce zinc absorption — the two compete for uptake pathways.
