What Taking Zinc Every Day Does to Your Body

Zinc is an essential mineral that helps the body function in a variety of basic ways, from supporting the immune system to keeping our metabolism humming. Fortunately, the human body doesn't need large amounts of zinc, and most of us get all the zinc we need from food. But there are some cases in which zinc supplementation could be warranted. These are some of the benefits of daily zinc, according to experts. Read on to find out more—and to ensure your health and the health of others, don't miss these Sure Signs You've Already Had COVID.

Zinc May Improve Immunity

"Zinc, a nutrient found throughout your body, helps your immune system and metabolism function," says the Mayo Clinic. "Evidence suggests that if zinc lozenges or syrup is taken within 24 hours after cold symptoms start, the supplement can help shorten the length of colds." One caveat: Using nasal sprays containing zinc is no longer advised—the practice has led to some people losing their sense of smell temporarily or permanently.

Zinc May Lower Blood Pressure

Zinc May Help Wounds Heal

"People with skin ulcers and low levels of zinc might benefit from oral zinc supplements," says the Mayo Clinic. Applying zinc topically may help wounds heal by encouraging collagen production and the formation of new skin cells, experts say.

Moisturizers and sunscreens containing zinc oxide are recommended by dermatologists 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 mineral sunscreen (such as those containing zinc or titanium dioxide) that are rated 30 SPF or higher.

Zinc May Slow Macular Degeneration

Doctors may recommend taking zinc to slow the eye disease AMD (age-related macular degeneration), which occurs when the part of the retina responsible for vision starts to degrade. The Age Related Eye Disease Study found that people with macular degeneration could slow down the damage by taking 80 mg of zinc (80 mg), along with vitamin C,  vitamin E, beta-carotene, and copper. Ask your doctor if you're concerned about your vision and if zinc supplementation might help.

These 5 Grocery Items Are Cheaper Than Ever Right Now

The grocery industry has been facing major disruptions. The combined effects of the pandemic, climate change, and economic uncertainty over the past couple of years have culminated in a series of supply chain breakdowns. For the consumer, this means supply shortages , shipping delays , and temporary store closures are becoming more commonplace – and all of the added production cost to suppliers is driving up food prices . The U.S. Bureau of Labor Statistics' Consumer Price Index report for January 2022 was released on Feb. 9, and it tells the story of cost trends for every spending category over the past year.

When Should I Take Creatine?

Creatine is probably the most well-researched supplement on the market today. Numerous studies have found positive adaptations in strength, power and muscle mass thanks to creatine supplementation—especially when it's combined with resistance training. Although the benefits of creatine are well-known to lifters, the best time to take it isn't common knowledge. Which leads us to some important questions:     Does an optimal time for consuming creatine exist?     If it does, should you take it before or after your workout? According to a new study published in the Journal of Exercise and Nutrition, the timing of creatine ingestion does indeed play a role in getting bigger and stronger. Creatine supplementation before resistance training increases muscular strength and lean muscle mass. Interestingly, taking creatine immediately after lifting weights results in greater muscle growth than taking it immediately before. However, in terms of strength gains, no difference betw
