Recommendations

Do not use this treatment:

It does not prevent cold symptoms, and it only slightly speeds up recovery. The treatment seems safe but pointless.

Doctors Say That Curefacts.com -  Tooltip icon

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.

Note that while infections with various strains of Corona viruses are responsible for most cases of common cold, the new corona virus strain, SARS-CoV-2, leads to an entirely different coronavirus infectious disease, COVID-19. The research of treatments for COVID-19 is still pre mature and not based on solid evidence. Therefore, at this stage, we can only speculate that effective treatments for common cold (and related Corona virus strains) may prove effective for Corona disease 2019 (COVID-19) and the related SARS-CoV-2 strain. Please don't count on it.
