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 does not need large amounts of zinc, and most of us get all the zinc we need from food. But there are some cases where zinc supplementation can be offered. These are some of the benefits of taking zinc daily.
Zinc, a nutrient found throughout the body, helps your immune system and metabolic function. Evidence suggests that if zinc lozenges or syrup are taken within 24 hours following the onset of cold symptoms, the supplement can help shorten the duration of the common cold. One caveat: nasal sprays containing zinc are no longer recommended – this practice has resulted in some people losing their sense of smell temporarily or permanently.
According to a 2020 meta-analysis of studies, zinc supplementation reduces systolic blood pressure. The authors note that zinc deficiency has been associated with high blood pressure in animal studies.
People with skin ulcers and low levels of zinc may benefit from oral zinc supplements. Experts say that applying zinc topically may 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) rated SPF 30 or higher.
Doctors may recommend zinc to slow the eye disease AMD (age-related macular degeneration), 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 the damage by taking 80 mg of zinc (80 mg), along with vitamin C, vitamin E, beta-carotene and copper.
