American doctors came to the conclusion that the high dose of vitamin D is not able to improve the condition of patients with moderate and severe COVID-19. The results of scientific work are published in Journal of the American Medical Association.
In the double-blind randomized placebo-controlled test, 240 patients with coronavirus were involved, which were divided into two groups. One group received vitamin D3 in a single dose of 200 thousand international units (IU) contained in peanut butter. The control group was given placebo in the form of peanut butter. All patients underwent a standard course of treatment, including the reception of antibiotics and anti-inflammatory drugs.
The main objective of the study was to test vitamin D as a means of potentially able to reduce the time staying in the hospital. However, scientists also appreciated its influence on the risk of income into the department of intensive therapy, intubation or death.
It turned out that there is no reason for using a high dose of vitamin D patients with severe COVID-19. However, this does not mean that there are no positive effects from the constant use of vitamin.
According to experts, older people and patients with chronic diseases, for example, with osteoporosis, should have a vitamin D level of more than 30 nanograms per milliliter of blood (NG / ml). For healthy adults, an acceptable amount is 20 ng / ml.
