PROPHYLAXIS

Prophylaxis means a measure to stop something before its occurence.

It was found that, 1000mg daily Vitamin C prophylaxis reduced the duration by 8% in adults and 13% in children. Also huge variation were seen in these results, some even stating there was no effect of Vitamin C propylaxis. These percentages are too small to be recommended to people as common cold prophylaxis.

A research was conducted in school children, where students were given prophylactic Vitmain C and were checked if this prophylaxis decreased the incidences or duration of common cold. Suprisingly, no effect was found neither in number of children becoming ill nor in the number of episodes nor in the mean duration of illness.

The above results were seen in normal, well nourished individuals who were not suffereing from any major disease. This suggests that Vitamin C supplementation is not necessary for Common Cold prevention. A healthy lifestyle and wholesome food will be enough to keep your immmunity good.

BUT

If you are have undergone a short period of physical strain such as severe exercise or a treck, or similar which is beyond your regular physical limits. Vitamin C prophylaxis is found to be useful.

Vitamin C 1000mg prophylaxis in such individuals can help in reducing the common cold symptoms and common cold duration.

This is because whenever we undergo any physically stressing event, our body’s immunity capacity decreases for a short period of time. And it is during that time, we require additional measure or supplements to increase the immunity power of our body.

So it will be good to start to start Vitamin C prophylaxis couple of days before u are planning for physically straining yourself.

Also if you are someone who suffers from a running nose maximum time of the year, then 1000mg Vitamin C prophylaxis can be useful to you as well.


TREATMENT

Talking about effect of Vitamin C on common cold treatment, the story doesn’t change that much from prevention.

When Vitamin C was started after the onset of comon cold symptoms, it was noted that Vitamin C did reduce the common cold duration and its severity by 14%-25% in various individuals. But there were hugh variations seen in the results. There are some studies which denied any beneficial effect of Vitamin C tablets in treatment.

It was recommended in a few met-analysis studies that Vitmin C should be advised according to individual’s experience on effect of Vitamin C on common cold.

Variation in results were largely dependent on the Vitamin C dosages given to the study subjects.

A dose of 1500mg to 2000mg on 1st day followed by 1000mg for 4-6 days was found to be effective in several studies.


CONCLUSION-

PROPHYLAXIS– only if you have undergone physical strain 

TREATMENT–  Beneficial, but should be tried on individual basis.
