Vitamin C intake for colds is unnecessary
The wet and cold weather of the past few days caused many people to catch a cold. Some patients try to treat themselves with additional vitamin C. However, according to scientific knowledge, such preparations have no influence on the symptoms and the duration of a cold.
Taking vitamin C for colds
Runny nose, cough, headache: A flu-like infection, the "simple" cold, can be caught several times a year. The symptoms start slowly and subside after a few days. If you rest and use the right remedies, the disease usually goes without major problems and usually heals within a few days. However, taking vitamin C supplements does not help.
Rest and drink a lot
If the throat scratches or the nose runs, some people try to fight the oncoming cold with additional vitamin C.
But studies show that such preparations "have no effect on the symptoms and duration of a cold if they are taken at the beginning of the cold," explains the Institute for Quality and Efficiency in Health Care (IQWiG) on its portal "gesundheitsinformation.de" .
However, there are some things that really help with colds.
The most important thing is to rest and drink a lot. Due to an increased fluid intake, the stubborn mucus dissolves better and the secretions in the nose are diluted.
Natural home remedies for colds
Many colds also swear by ginger tea. The miracle bulb ginger has an anti-inflammatory effect. In addition, the sharpness of this natural remedy irritates the mucous membranes and promotes blood circulation.
Cooking steam inhalations for the face are also a proven home remedy for colds. These have an expectorant, secretion-promoting and anti-inflammatory effect.
It is also advisable to place a bowl of water on the heating and ventilate it several times a day.
Experts usually also recommend going for a walk from time to time with a cold - but not if you have a fever.
Shortened illness duration
Even if the intake of vitamin C at the beginning of the cold no longer has a proven effect on the symptoms and the duration of the illness, the preventive intake can certainly make sense.
For example, the IQWiG writes on "informedhealthonline.org" that studies show "that long-term daily intake did not prevent the common cold, but shortened the duration of the common cold by about 10 percent." alleviate the cold symptoms a bit. “Because:“ Some studies examined the preventive effects of vitamin C in people who were briefly exposed to a very high physical strain due to sport, often in connection with cold. These included, for example, marathon runners and soldiers who did winter exercises in the mountains. In the studies, the participants started taking vitamin C preventively two to three weeks before the very heavy load. This prevented about half of all colds. ”
According to experts, the daily requirement of an adult for vitamin C is 100 milligrams. Most people in this country eat enough of it through food. (ad)
