Vitamin D is known to serve many advantages to the body but thinking that its supplements can help you control or ward off your common cold would be wrong, revealed the findings of the new study that has contradicted several of the previous research suggesting that the vitamin and its supplements might have a protective effect upon the condition.
To conclude some firm results, researchers at the University of Otago in New Zealand and Harvard Medical School conducted a study in the year 2010 and 2011 over 322 healthy adults in Christchurch, N. Z.
They gave half of the adults an initial pill that contained 200,000 international units (IU) of vitamin D, which in the next month was changed to another pill and then was reduced to half the dose monthly for 18 months. On the other hand, the other half contestants were given the same schedule of placebos.
The experts noticed no improvement in the number of colds from the Vitamin D supplements, also the length or severity of the cold as compared with placebo did not show any change. Multivitamins generally include strengths from 50 IU to 1,000 IU, the study used 200,000 IU of vitamin D, which is equivalent to 5,000 micrograms.
