Zinc
Zinc- Reliable and relatively consistent scientific data showing a substantial health benefit.
- Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
- For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

Comments about GNC Zinc 100:
I have been taking 100 mgs of Zinc for years for the
control of cold sores on the mouth (herpes symplex).
I went from continuous huge aggrivating sores that would last up to two weeks on my lip to an extremely tiny bump perhaps once a year that I barely notice. I have not noticed any toxicity.
Actually, zinc strenghthens the immune system.Comments about GNC Zinc 100:
I believe that the dosage of this tablets are way to high and due to the high dosage they cause nausea. I read online the highest recommended intake of Zinc daily should be about 30 mg and this tablets are made with 100 mg, more than 3 times the recommended dosage. Zinc can be toxic when taken in high dosage I recommend you go for a lower dosage tablet. Also beware that if you are taking antibiotics while you take Zinc, the Zinc will decrease the effect of the antibiotic, it will not cancel it out as some think but it will decrease the effectiveness of the antibiotic you are taking.
