Zinc's Upper Limit: A Multivitamin Stacking Warning

If you already take a multivitamin, this formula's undisclosed zinc dose is worth a specific, careful check.

Why this stacking risk is real

Zinc has a tolerable upper intake level of 40 mg per day for adults — if you take a zinc-containing multivitamin already, you may be getting a meaningful amount, and you cannot count what an undisclosed-dose product is adding on top.

What to actually do about it

Check your other supplements for zinc content specifically, and consider contacting the brand directly to ask about the amount in this formula before assuming it's safe to stack.
