ODying on Vitamin A can affect immune system function
Doctors often recommend vitamin A as a dietary supplement to the frail and strong alike. It is a fat-soluble vitamin that has a wide range of health benefits to offer and has been vouched to bring life back to its lively self. Because it cannot be produced by our body, it has to be derived from food and with the urban lifestyles today, it becomes rather impossible to meet daily requirements of not just this important nutrient but also many others.
Too much of it can shut the immune system of the body, thus opening door to infections that the person may otherwise have been immune to. According to a study, an excessive consumption of vitamin A makes the body sort of “forget” the past infections. It further added that a even though vitamin A supplements tend to have a profound effect on the health benefits of the vitamin when someone is deficient, the supplementation of vitamin A above normal levels can be detrimental to health.
Mihai Netea from the Radbound University Medical Center in Nijmegen, The Netherlands, said that the study helps in explaining how vitamin A has anti-inflammatory effects and how by doing so it opens the door to identification of novel ways to modulate immune response as well as to restore function in those situations where it is dis-regulated.
The amount of vitamin A that one needs depends on one’s age as well as reproductive health. Getting a lot of vitamin A can lead to nausea, dizziness and even death.
