Vitamin D, Magnesium, and Vitamin B12 for COVID-19: Video Summary The researchers hypothesized that patients given the nutrient combination would be less likely to require oxygen therapy, intensive care support, or both, compared to those who did not receive the nutrient combination Out of 43 consecutive COVID-19 patients who were 50 years or older and did not require oxygen therapy upon admission, 17 received the vitamin D, magnesium, and vitamin B12 (DMB) combination, while 26 patients did not Those receiving the DMB combination were given oral vitamin D (1000 IU/day), Magnesium (150 mg/day), and Vitamin B12 (500 mcg/day) All patients enrolled were followed for 30 days or until hospital discharge to track any deterioration leading to oxygen therapy or the need for intensive care support The Supplement Combination had a Significant Effect 71% fewer patients required subsequent oxygen therapy or intensive care support in the DMB group than the non-DMB group , and the difference was significant 3 out of the 17 patients (18%) in the DMB group required subsequent oxygen therapy or intensive care support, two of which required the therapy within 24 hours after their first supplement dose (meaning the supplements may not have had time to make a difference) 16 of the 26 (62%) patients not receiving the DMB supplementation required subsequent oxygen therapy or intensive care support Odds Ratio (OR) is a measurement that shows the strength of association between an intervention and an outcome
