Zinc Gluconate
MineralThe most common zinc salt in multivitamins, lozenges, and immune products, containing about 14.3% elemental zinc.
Typical: 10–25 mg
Zinc Picolinate
MineralZinc chelated with picolinic acid, a tryptophan metabolite that is proposed to aid mineral transport across the gut wall.
Typical: 10–25 mg
Zinc Bisglycinate
MineralZinc chelated with two glycine molecules, sold as a gentle, well-absorbed form for people who get nausea from zinc salts.
Typical: 10–25 mg
Zinc Citrate
MineralA 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 Bisglycinate
MineralCopper chelated with two glycine molecules, supplying about 25% elemental copper in commercial grades.
Typical: 0.5–2 mg
Zinc Oxide
MineralThe densest zinc source at about 80% elemental zinc, which is why it is the default in multivitamins and low-cost tablets where space is tight.
Typical: 10–25 mg
Zinc Monomethionine
MineralA complex of zinc with the amino acid L-methionine, best known under the OptiZinc trade name, carrying roughly 21% elemental zinc.
