Well-dosed for everyday immune and skin health support. **Zinc** at 22mg per tablet sits comfortably in the 15–30mg clinical range, and the glycinate chelate form is one of the best-absorbed options available — meaning you're likely getting more of it into your bloodstream with less stomach discomfort.

At 22mg, you're well above the 11mg RDA but safely under the 40mg tolerable upper limit, which makes this practical for daily long-term use without the copper depletion risk that comes with higher zinc doses.

One thing to keep in mind: if you're taking zinc primarily for immune support during acute illness, the studied doses tend to run higher (30–40mg). At 22mg, this is better positioned for everyday maintenance than for short-term therapeutic use.
