50 Zinc Acetate Lozenges – 18mg of zinc per lozenge. Studies generally support the use of zinc for the common cold and similar upper-respiratory tract infections. The evidence in zinc’s favor is substantially better than that for any other purported cold remedy, as per numerous trials and meta-analyses. [1, 2, 3, 4]

Zinc’s potential utility as a prophylactic measure against upper-respiratory tract infections is limited by the fact that it is only effective in a very narrow range of formulations, for zinc’s most plausible mechanism of action requires contact between unbound, ionic zinc and infected cells. This has several implications:

For upper respiratory tract infections, capsules will prove poorly-effective or entirely ineffective. Lozenges, instead, are the ideal dosage form.

Very few common zinc compounds release sufficient amounts of ionic zinc at physiologic pH; zinc acetate and zinc gluconate are, at the present time, the only viable sources of ionic zinc. Of the two, zinc acetate is considerably more effective.

Zinc acetate can react with other ingredients in the lozenge, and in saliva, which typically results in stable reaction products that do not release ionic zinc at physiological pH. Therefore zinc acetate lozenges must not contain excipients such as tartaric acid, stearate, magnesium, ascorbic acid, among many others. They must not contain Vitamin C. They should not contain plant extracts.

Although zinc is a common supplement, effective zinc lozenges that have been properly formulated are exceedingly rare. Optimized Zinc Acetate Lozenges, by Antaeus Labs, are the best available anywhere. Purchase with confidence.
