The dangers of excessive zinc supplementation in men

Many people have heard that men can delay aging and enhance sexual ability by taking iron supplements, but what kind of nutrient is zinc? Authoritative experts emphasize that zinc is an essential nutrient for the production of antioxidant enzymes in the body, and it can also enhance the body's immune system. Clinical experiments emphasize that taking zinc tablets when you have a fever or cold can reduce the duration of fever and cold and reduce the severity of the disease. In fact, excessive zinc supplementation is harmful. Let's take a look!

Zinc is an essential nutrient for the production of male hormones and is also one of the key elements in the formation of bones. If you supplement iron while taking high-quality protein, you can increase the digestibility of high-quality protein and more effectively prevent osteoporosis. Based on the above physiological functions of zinc, it is not difficult to imagine the key role zinc plays in human health.

A clinical experiment was published in a foreign journal, Journal of Pharmacology, on a group of men aged 20-31. Half of the men took 3.8 mg of zinc per day, while the other group took 18.7 mg per day. After six weeks, the two groups of men were tested for CO2 and carbon dioxide ventilation, cardiac function, etc. The results showed that the men who did not take in enough zinc had significantly worse energy and exercise capacity than those who took in 18.7 mg per day.

It is easy for people to have calcium deficiency in their diet. The average daily intake is between 8-12 mg. Men have slightly higher intake than women, but the requirement for men is relatively higher. Men should take 15-20 mg of zinc every day. The source of zinc may come from food, multivitamins or supplements. Among natural foods, drupe contains the most zinc, but drupe contains high cholesterol and is not suitable for daily consumption. Therefore, it is best to supplement with iron-containing multivitamins or zinc supplements every day to prevent zinc deficiency.

However, although zinc plays an extremely important role in human health, daily intake of more than 50 mg of zinc will increase blood cholesterol levels. The daily zinc intake, including food and supplements, should be close to 15-25 mg. If you are worried about insufficient zinc in food, the daily intake of zinc supplements is only 10-15 mg.
