VITAMIN C AND THE COMMON COLD

One hundred sixty-eight volunteers were randomized to receive a placebo or a vitamin C supplement, two tablets daily, over a day period between November and February. They used a five-point scale to assess their health and recorded any common cold infections and symptoms in a daily diary. Consequently, volunteers in the active group were less likely to get a cold and recovered faster if infected. Few side effects occurred with the active treatment, and volunteers reported greatly increased satisfaction with the study supplement compared with any previous form of vitamin C. This well-tolerated vitamin C supplement may prevent the common cold and shorten the duration of symptoms. Volunteers were generally impressed by the protection afforded them during the winter months and the general acceptability of the study medication. Download to read the full article text.

It is generally believed that the consumption of vitamin C prevents its appearance, but the actual efficacy of this measure is controversial. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. We concluded the consumption of vitamin C does not prevent the incidence of common cold. The common cold is one of the most common diseases in the general population. The term "common cold" does not refer to a specific condition, but to a group of symptoms such as nasal obstruction, sore throat, cough, lethargy and asthenia, with or without fever. These symptoms have multiple etiological agents such as rhinovirus, adenovirus, syncytial virus, etc.

Huge doses of vitamin C, from one to ten grams daily, are recommended by some scientists as a treatment for and preventative against the common cold. But the prolonged use of such large doses may be dangerous, because there is evidence that breakdown products of vitamin C formed in the body for instance, oxalic acid are a threat to health. Also large doses of the vitamin can enhance the dangerous effects of certain toxic substances in food. It would obviously be both easier and safer for the public to take vitamin C in the smaller quantities in which it is found in certain foodstuffs. Citrus fruits, such as oranges and lemons and also blackcurrants, are particularly rich in vitamin C, the average orange containing about 30mg. Report bugs here.

I have, however, formulated the hypothesis which has not yet been tested by experiment that the effectiveness of ascorbic acid in providing protection against viral diseases results from its function in the synthesis and activity of interferon in preventing the entry of virus particles into the cells. The discovery of interferon was reported in by Isaacs and Lindenmann. It is a protein that is produced by cells infected by a virus and that has the property of spreading to neighboring cells and changing them in such a way as to enable them to resist infection. In this way the interferon ameliorates the disease. I estimate that for many people 1 g [gram] to 2 g per day mg to mg per day is approximately the optimum rate of ingestion.

To investigate whether vitamin C is effective in the treatment of the common cold. Extra doses of vitamin C could benefit some patients who contract the common cold despite taking daily vitamin C supplements.

Meeting the recommended levels of intake for all essential micronutrients is important for optimal immune function see Immunity In-brief article. When it comes to the common cold specifically, there is evidence that routine supplementation with vitamin C can reduce the occurrence and duration of the common cold in certain individuals. Use of oral zinc lozenges may influence cold symptoms and duration, but there are important caveats associated with their use. The common cold is a viral infection of the upper respiratory tract nose and throat. Any one of hundreds of viruses can cause a common cold, but rhinoviruses are the most common culprits. It is possible to get a cold at any time of the year.

Vitamin C and the Common Cold is a popular book by Linus Pauling , first published in , on vitamin C , its interactions with common cold and the role of vitamin C megadosage in human health. A Nobel Prize-winning chemist and activist, Pauling promoted a view of vitamin C that is strongly at odds with most of the scientific community, which found little evidence for the alleged health benefits of greatly increased vitamin C intake. The book characterizes the inability of humans and some other animals to produce vitamin C in terms of evolution and Pauling's concept of "molecular disease" first articulated in his study, " Sickle Cell Anemia, a Molecular Disease ".
