That depends on the type of mineral and supplement. Some naturally-occurring minerals, including magnesium and potassium, are attached to proteins (or several individual amino acids) that make it easy for the body to absorb the substance. Most minerals sold as dietary supplements are attached to a single carrier molecule — a structure that doesn’t occur in nature. Take magnesium supplements containing magnesium citrate as an example; you won’t find such a chemical structure in nature. The only way to get nature-identical electrolytes from a supplement is to use one that contains whole-food ingredients. Keto-Beam would be such an example.
