Major Zinc 50 mg
Brand: Major · Form: CAPSULE [E0159] On Market
Our assessment
Our assessment: Major Zinc 50 mg is a high-dose supplement. The evidence shows that while zinc is essential for immune function, a 50 mg dose exceeds the recommended daily allowance for most adults. You should be cautious with this product, as long-term use of high-dose zinc can lead to copper deficiency and other issues. Data on this specific product's efficacy is limited to the ingredient zinc, not this particular formulation.
How it works
Think of zinc as a critical helper for your immune system. It supports the development and function of immune cells and acts as an antioxidant, protecting your cells from damage. Zinc also plays a role in wound healing and DNA synthesis [NIH ODS].
Safety profile
The FDA received a total of 592,059 adverse event reports across all supplements, though data specific to this product is not available. For the ingredient calcium, which is included in the same data set, high levels can cause constipation, nausea, abnormal heart rhythms, and a high risk of death from heart disease [FDA data] [NIH ODS]. You should be aware that high doses of zinc (like 50 mg) can cause nausea, vomiting, and stomach cramps, and may interfere with your body's ability to absorb copper [NIH ODS].
Our recommendation
Start with a lower dose, around 8-11 mg daily for most adults, unless you have a confirmed deficiency. For Major Zinc 50 mg, consider taking it with food to reduce stomach upset. Do not take this supplement long-term without medical supervision. Choose a form that is well-tolerated, such as zinc picolinate or zinc citrate [NIH ODS].
