Vitamin C (vitamin) for prevention of Pneumonia in healthy Adults

  • Insignificant

    Bottom Line

  • Prevention with Vitamin C (Ascorbic acid tablets). 2 studies conducted, with 2,109 young adults and soldiers. Prevents 1 case of Pneumonia in 66 adults. Seems safe.



Consider this treatment:

It does seem to prevent most Pneumonia cases, but take into account that such cases are pretty rare to begin with in healthy adults. Side effects seem negligible.

Doctors Say That

Only soldiers and young adults participated in the included studies. Further research with older and more representative adult population is required in order to validate the conclusions.

Any excess of Vitamin C (Ascorbic acid) is evacuated from our body through the urine. This makes vitamin C pretty safe even in high dosages.

Vitamin C, also known as ascorbic acid and L-ascorbic acid, is a vitamin found in food and used as a dietary supplement. As a supplement it is used to treat and prevent scurvy. Evidence does not support use in the general population for the prevention of the common cold. It may be taken by mouth or by injection. It is generally well tolerated. Vitamin C was discovered in 1912, isolated in 1928, and first made in 1933. (source)
