If you're reaching for this to support your immune system, you're well past the effective dose. **Zinc** comes in at 50mg per tablet, while the clinical research for immune function typically uses 15–30mg daily. The amino acid chelate form absorbs reasonably well, so a single tablet gives you a fully usable dose with room to spare.

There's also 125mg of calcium in each tablet, but that falls below the 200mg point where a supplemental dose starts to matter, and it won't meaningfully add to your daily calcium intake. Treat this as a zinc product, not a two-mineral one.

The bigger thing to know: 50mg sits above the 40mg daily upper limit for zinc. That's manageable for short stretches, like fighting off a cold, but taking it every day long-term can deplete your copper and tip the zinc-to-copper balance your body relies on. If you plan to use it beyond a few weeks, consider a lower daily dose or pairing it with a small amount of copper.
