This zinc supplement delivers 25mg of elemental **Zinc** for immune support, sitting comfortably inside the 15-30mg clinical range and well under the 40mg daily safety ceiling, so it's suited to long-term use. The "3-in-1" refers to the zinc source rather than three separate ingredients: the dose is built from a blend of zinc picolinate, glycinate, and citrate, and the first two are forms your body absorbs efficiently.
The more meaningful addition is **Copper** at 2mg. Taking zinc every day competes with copper for absorption and can quietly drain your copper stores over months, so including it here guards against that. The 2mg dose sits right at the top of copper's recommended range, delivered as well-absorbed copper glycinate, and the roughly 12-to-1 zinc-to-copper ratio is a sensible balance for ongoing use.
One tablet a day on an empty stomach gives you a full, well-absorbed immune dose without the copper-depletion risk that comes with zinc taken on its own. If you already use a multivitamin containing zinc and copper, stacking this on top could push you toward the upper end of both, so it's worth tallying your total daily intake.
