Vitamin D

Vitamin D participates in your body's immune reactions and improves the protection of bronchial and epithelial cells, helping to combat respiratory diseases. Today, there is enough data that suggests that a vitamin D deficiency makes the coronavirus far harder to fight. Many countries recommended taking the same dosage of vitamin D per day — even before the pandemic. US National Insitutes of Health, Office of Dietary Supplements recommends to take600 IU (International Units) for people under 70 years of age, 800 IU for those over 70. Dosage above 2,000 IU per day should be taken only if prescribed by a physician.

Zinc

Zinc is required for cell division and synthesis of proteins. It increases the resistance of erythrocytes as well as participates in immune processes and anti-inflammatory reactions. Zinc provides for the protection of respiratory cells against infections, decreasing the risk of pneumonia complications. This microelement can reduce the activity of virus enzymes that lose the ability to replicate while improving our chances to fight infection. In ГЫ, around 20 % of adults are deficient in zinc. The daily dosage for a healthy individual is 8 mg for women and 11 mg for men. Those who are deficient in zinc should take 50 mg one time per day for 3 months.

Vitamin C

Vitamin C helps to prepare our immune response by stimulating the synthesis of interferons, which are our natural protectors against viruses. An absence of ascorbic acid leads to the fragility of blood vessels, lower immunity, and anemia. The research has shown that vitamin C can reduce the period of cold symptoms by half a day up to one day when taken as a part of therapy. The recommended daily dosage is 70–100 mg for men and 65–75 mg for women. It is not necessary to take ascorbic acid permanently, as excess may not be absorbed and can lead to kidney stones.

Omega-3

Polyunsaturated fatty acids have an anti-inflammatory effect and ease the course of the disease, making the walls of the cells stronger and blocking the virus from penetrating them. Natural sources of Omega-3 include fatty fish (salmon, halibut, herring), linseed, and olive oil. The recommended daily dosage of Omega-3 for supporting the immune system and complex therapy of various disorders is 2,000 mg, which can be taken in capsules.

Vitamin В12

Scientists in India have concluded that vitamin B12 combats the virus and blocks it from replicating. In Singapore, research has been done to study the interaction of vitamins B12, D3, and magnesium. The research that this combination eases the course of coronavirus. The dosage of the vitamin did not exceed 500 mcg per day. Too much vitamin B12 increases the risk of thrombus formation, which is the main danger of COVID-19. Therefore, taking vitamin B12 during coronavirus should only occur if recommended by the physician who is aware of its concentration in the blood.
