The main recommendation for strengthening the body during a coronavirus pandemic is significant and that patients suffering from chronic diseases, especially after a long period of home isolation, and before returning to the collectives, regularly take zinc and vitamin C and D. Overdose does not occur often, but if the recommended doses are exceeded, vitamin C can cause various ailments, such as nausea, vomiting and diarrhea, which is more common in patients with kidney disease.

Vitamin C is very important for our body and general functioning in order to have enough energy during the day, so it is necessary to take enough vitamins and not overdo it.

-The daily dose of vitamin C recommended for women is 75mg per day

-The daily dose of vitamin C recommended for men is 90mg per day

Absorption of vitamin C is disrupted by stress, high body temperature, tobacco, alcohol, antibiotics, salicylates and oral contraceptives. Vitamin C is a water-soluble vitamin. Our body does not store vitamin C, and does not produce it on its own. Because of this, it is important to consume foods that are rich in vitamin C on a daily basis. Consuming high amounts of vitamin C can lead to side effects. Some of them are problems with the digestive system, or kidney stones. When the body is overloaded with higher doses of this vitamin, it begins to accumulate in the body. This potentially leads to symptoms of excessive sweating.

Zinc is an essential mineral, it is found in small amounts in the earth's crust. In food, it is most often found in foods of animal origin, and less in foods of plant origin. It is very important for the functioning of the whole organism, and since the organism does not synthesize it, we must take it in through food and supplements, especially in the winter.

Zinc is found in small amounts in the body, about 2 or 3 grams. But because of that, the organism felt a small deficit. Zinc participates in many processes in the body. To name some important roles of zinc to understand how important it is to us:

It participates in protein synthesis, thus stimulating mental and physical growth and development.

Contributes to the strengthening of immunity and resistance of the organism, reduces the possibility of colds. Vitamin A promotes the resorption of zinc, and in combination with vitamin C it is an excellent choice for the prevention of colds.

In the brain, it acts as a modulator and has calming effects, thus the deficiency causes nervousness, depression, poor concentration, poor memory…

Excess zinc in the body rarely occurs, and if the amounts are greater than 200 mg), abdominal pain, nausea and vomiting occur.

Other symptoms include dehydration, lethargy, anemia and fainting.

Prolonged intake of large amounts of zinc in the body can cause a lack of copper in the body. This can occur if more than 25 mg of zinc is ingested daily. Long-term intake of zinc in amounts over 150 mg per day leads to reduced immune system function and reduced HDL cholesterol levels leading to heart disease.

Increased zinc intake during pregnancy can be harmful to the fetus.

The best measure for everyone is moderation, and that also applies to vitamins and minerals. Many people do not know this, but too many vitamins and minerals can cause serious health problems.
