Biomins is formulated for individuals at high risk for mineral deficiencies. Mineral deficiencies frequently occur in the elderly, in children and teenagers, and in individuals with eating disorders. Taking certain medications can also result in mineral deficiencies. In formulating Biomins, Thorne concluded that dicalcium malate and dimagnesium malate (two molecules of each mineral bound to one molecule of malate) are the forms of calcium and magnesium that best optimize both absorption and concentration (how much fits in a capsule).

Albion® Laboratories – an innovator of mineral chelates since 1956 – supplies the majority of the minerals in the BioMins formula. Thorne believes that Albion's glycinate chelates – of iron, zinc, copper, chromium, manganese, molybdenum, and boron – exhibit excellent absorption and tolerability. Biomins also utilizes Ferrochel® – an exceptionally well tolerated form of iron.
