High risk groups for zinc deficiency are: alcoholics, vegetarians, pregnant and lactating women, older infants exclusively breastfed, people with sickle cell disease, people with gastrointestinal and other diseases, people consuming high doses of iron supplements and people taking diuretics. If you fit into one of these categories, you should really consider including a zinc supplement in your daily routine.
In addition to ear health, zinc is beneficial for a healthy immune system; thought to help with common cold symptoms; help with the healing of cuts and wounds, and healthy skin; and helps to prevent and reduce the potential for age-related eye damage. Like ginkgo biloba, zinc is also a powerful antioxidant, scouring toxins from the body.
