Zinc is an essential mineral for healthy metabolism and is found in shellfish (particularly oysters), red meat, nuts (cashews are a good choice) and some fortified cereals. The recommended dietary allowance (RDA) of zinc for adults 19 and up is 11 milligrams for men and 8 milligrams for women.
Research shows that zinc intake can influence your health in a number of ways.
The Common Cold
There is evidence to suggest that this immune-boosting supplement can help shorten the length of a cold.
In fact, a 2008 study found that subjects who took a zinc supplement within 24 hours of symptom onset had less severe symptoms for a shorter period of time than cold-suffering subjects who took a placebo.
Zinc is essential to healthy skin. Zinc deficiency has been linked to delayed wound healing.
People with chronic skin ulcers, such as diabetics, could benefit from a daily zinc supplement to ensure their zinc serum levels are normal and skin healing is not impaired.
Age-Related Macular Degeneration
Age-related macular degeneration or AMD is a common eye disease causing vision loss primarily in adults aged 50 and older.
Those with a family history of AMD are at higher risk, but lifestyle choices including a healthy diet and supplementation may help slow the disease’s progression.
Zinc is an important part of the AREDS formulation—a combination of supplements found in the National Eye Institute’s Age-Related Eye Disease Study—that may help prevent or slow the progression of AMD.
Here are a few zinc supplements we recommend:
At the first sign of cold symptoms, offer one of these soothing lozenges to your little one.
These gluten-free, non-GMO capsules contain 30 milligrams of zinc picolinate to support a healthy immune system.
Women who are pregnant or breastfeeding need slightly more zinc. Consult your doctor about a dose that is right for you.
