Zinc is essential for immune function and cellular metabolism, with strong evidence supporting its role in supporting the immune system. However, the limited evidence coverage for this specific formulation and a safety score of 60 suggest potential concerns regarding long-term toxicity or mineral imbalances.

Warnings & Precautions

Warning: NOT INTENDED FOR USE BY PERSONS UNDER THE AGE OF 18. KEEP OUT OF THE REACH OF CHILDREN.

If you are pregnant, breast feeding, have known medical conditions (including kidney or liver disease) or are taking prescription or OTC medication(s) consult with your health care practitioner before using this product.

Fiber binds with zinc and can inhibit the absorption and availability of copper. While this can be a good thing for individuals with overly high copper levels, it can be a problem for people with copper deficiency.

Some researchers and health practice professionals recommend that individuals supplementing with more than 50mg daily zinc, take 2mg of supplemental copper so as to prevent copper deficiency. Take any antibiotics 2 hours apart from a zinc supplement.

Signs of zinc toxicity include stomach upsets, diarrhea, vomiting, and kidney problems. Zinc toxicity can be fatal.
