Zinc is an essential mineral that helps the body function in several essential ways, from supporting the immune system to keeping our metabolism active. Fortunately, the human body doesn’t need large amounts of zinc, and most of us get all the zinc they need from food. But there are some cases where zinc supplementation may be offered. These are some of the benefits of taking zinc daily.
Zinc, a nutrient found throughout the body, helps the immune system and metabolic function. Evidence suggests that if zinc lozenges or syrup are taken within 24 hours of the onset of cold symptoms, the supplement may help shorten the duration of the common cold. A warning: zinc-containing nasal sprays are no longer recommended – this practice has led some people to lose their sense of smell temporarily or permanently.
According to a meta-analysis of 2020 studies, zinc supplementation reduces systolic blood pressure. The authors note that zinc deficiency has been associated with hypertension in animal studies.
People with skin ulcers and low zinc levels may benefit from oral zinc supplements. Experts say topical zinc application can aid wound healing by encouraging collagen production and the formation of new skin cells.
Dermatologists recommend using moisturizers and sunscreens containing zinc oxide to prevent sun damage, which can cause premature skin aging and cellular changes that can lead to skin cancer. Experts recommend using a daily moisturizer with a mineral sunscreen (such as those containing zinc or titanium dioxide) with SPF 30 or higher.
Doctors may recommend zinc to slow AMD (age-related macular degeneration) eye disease, which occurs when the part of the retina responsible for vision begins to deteriorate. The Age-Related Eye Disease Study found that people with macular degeneration can slow down the damage by taking 80 mg of zinc (80 mg), along with vitamin C, vitamin E, beta-carotene and copper.
