Calcium Magnesium Zinc with D3

Nature Made's trifecta of worst-absorbed mineral forms: calcium carbonate, magnesium oxide, zinc oxide. Your body absorbs a fraction of the label claims. They already make magnesium glycinate. Apply that thinking here, Nature Made.

4.5/10
POOR

The trifecta of budget forms: calcium carbonate, magnesium oxide, zinc oxide. Three minerals, three of the worst absorbed forms. D3 at 400 IU is too low. Nature Made can do better. They proved it with their glycinate.
