Core Minerals is a foundation supplement: twelve minerals plus a small amount of vitamin D3 in one capsule formula. The minerals are chelated forms, glycinate, picolinate, citrate, malate, which are the forms I prefer because the body assimilates them well. There is no iron, which suits many people in my practice who do not need it.

Why does this matter? Minerals provide tissue support, nerve signaling, muscle function, and are involved in dozens of enzyme systems. People eating a processed diet, or anyone with absorption issues, often run low on key minerals without knowing it. A broad mineral complex covers the gaps caused by a narrow diet.

The D3 is there for a practical reason: calcium absorption depends on vitamin D, so pairing them makes sense. Iodine comes from kelp, magnesium and calcium sit at 300 mg each, zinc at 15 mg as picolinate. The doses are sensible, not megadoses.

A formula like this has not been tested as a whole in clinical trials; the research base comes from the function of individual minerals. Zinc alone has a deep literature on immune function, and that is the best-studied mineral in this blend. The rest rests on nutrient science.

How I use it: as a daily foundation, four capsules a day split morning and evening with food. Divided dosing absorbs better than one big dose. If pregnant or nursing, review it with your physician first, and anyone taking medication should check timing, since minerals can bind some drugs.
