Food Science Of Vermont Multi-Source Cal-Mag Tablets, 90 Count

What the brand says

Food Science of Vermont's multi-source cal-mag contains three types of chelated calcium calcium citrate, calcium aspartate and calcium carbonate so your body can assimilate the minerals efficiently. The calcium and magnesium potencies are balanced in a 1:1 ratio, at 450 mgs of each and vitamin D3 is added to make this a complete formula. A deficiency in vitamin D3 can inhibit your body's ability to absorb calcium and magnesium.
