The organic selenium form found in Brazil nuts, grains, and selenium yeast, in which selenium replaces sulfur in the amino acid methionine.

Typical: 50–200 mcg

A zinc salt of citric acid with a relatively high zinc content of about 31%, giving it a compactness advantage over gluconate and picolinate.

Typical: 10–25 mg

Copper chelated with two glycine molecules, supplying about 25% elemental copper in commercial grades.

Typical: 0.5–2 mg

A copper salt of gluconic acid, about 14% elemental copper, and one of the most widely used copper sources in multivitamins because it is water soluble, inexpensive, and has a long safety record.

Typical: 0.5–2 mg

An inorganic selenium salt that is about 46% selenium by weight, inexpensive, and readily converted to selenide for selenoprotein synthesis.

Typical: 50–200 mcg

Manganese chelated with glycine, about 15% elemental manganese in commercial grades, used in bone, joint, and antioxidant formulas where manganese serves as a cofactor for enzymes involved in cartilage and bone matrix formation.

Typical: 1–5 mg

A water-soluble manganese salt of gluconic acid with about 11–12% elemental manganese, common in multivitamins and bone formulas as an inexpensive, mild-tasting source.

Typical: 1–5 mg

Molybdenum chelated with glycine, one of the forms NIH ODS lists for supplements along with sodium molybdate and molybdenum chloride, with no comparative bioavailability data among them.

Typical: 45–150 mcg

A complex of zinc with the amino acid L-methionine, best known under the OptiZinc trade name, carrying roughly 21% elemental zinc.

Typical: 10–25 mg
