Does taking zinc daily have negative side affects?

Taking zinc supplements daily can have negative side effects if dosages are too high. For instance, consuming over 100 milligrams of zinc per day can lead to immune suppression, reduced levels of HDL cholesterol, and decreased copper status. Most evidence supports using zinc in doses ranging from 15 to 30 milligrams daily for general health, which is considered safe for most adults 1 2.

Excessive zinc intake can also interfere with the absorption of other minerals such as copper and iron, potentially leading to deficiencies. It's important to balance zinc intake, especially if you're at risk for these deficiencies. Nausea is another common side effect when taking zinc, which can often be mitigated by consuming the supplement with food 3.

It's always recommended to consult with a healthcare provider before starting any new supplement regimen, especially if you have specific health conditions, are pregnant, or taking other medications 2.
