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.
Three minerals in their worst-absorbed forms: calcium carbonate, magnesium oxide (4% absorption), zinc oxide. Calcium at 333mg (33% optimal), magnesium at 133mg (33% optimal, and only ~5mg actually absorbed from oxide), zinc at 5mg (33% optimal). D3 at 400 IU is below minEffective (1000 IU). Every leading ingredient is underdosed AND in a poor form.
