In the course of studies conducted by scientists to find out as much as possible about COVID-19, an interesting fact about vitamin B12 has been discovered.

Lack of this vitamin in the body at this time of pandemic is a problem because it increases the risk of death from COVID-19 in humans and especially in old age.

Vitamin B12 deficiency may not be properly diagnosed in some cases, however the consequences of such a thing can be fatal for someone affected by coronavirus.

Insufficient levels of B12 can subject the immune system and impede the bodyâ??s ability to produce antibodies to viral infections.

Severe vitamin B12 deficiency can even cause hyperomocystinemia, a condition that can cause fatal blood clots in the brain, lungs and lower legs.

The required amount of vitamin B12

Vitamin B12 supplements offer promising support for the health of the brain and the whole organism.

But in addition to supplements sold in pharmacies, you can also get vitamin B12 through a healthy diet.

Vitamin B12 levels are determined by blood tests. Its normal levels are considered to be 200 to 900 picograms / milliliters (pg / ml). Most experts agree that any level below 200 pg / ml is a deficiency of the vitamin in the blood.

Other experts advise that the level of 350 pg / ml is also optimal.
