Vitamin-C is at the top of the list of immune boosters for many reasons. There has been extensive research regarding the immune-boosting effects of Vitamin-C than perhaps any other nutrient. Vitamin-C supplements are inexpensive to manufacture, and it’s available naturally in most fruits and vegetables. There is also a vitamin-C-fortified version of just about anything. Here’s what the research shows about how this mighty vitamin protects your body.
Vitamin-C increases the production of infection-fighting white blood cells and antibodies and increases levels of interferon. Interferon is an antibody that coats cell surfaces, preventing the entry of viruses. Vitamin-C also reduces the risk of cardiovascular disease by raising levels of HDL (good) cholesterol while lowering blood pressure. Vitamin-C also interferes with the process by which fat is converted to plaque in the arteries. Those whose diets are higher in vitamin-C have lower rates of colon, prostate, and breast cancer.
You don’t have to take in massive amounts of vitamin C to boost your immune system. Around 200 milligrams a day seems to be a generally agreed-upon amount. That can easily be obtained by eating at least six servings of fruits and vegetables a day. If you use vitamin-C supplements, it’s best to space them throughout the day rather than take one large dose. Excessive vitamin-C intake will just end up excreted in the urine.
