Every year the medical profession and government authorities
encourage citizens in many developed countries to get immunized against the current form of influenza virus. This year is no different, particularly with the "dreaded" swine flu still on everyone's minds. While the decision to get vaccinated is an individual one with both pros and cons, consider that a natural approach, namely supplementation with specific nutrients such as vitamin D, can boost immune function and may play an important role in the prevention of respiratory tract infections.
In recent years, studies have shown that vitamin D is an important modulator of immune function. Some authorities suggest it has the potential to reduce the risk of life-threatening influenzas based on the initial observation that influenza normally strikes in countries during the colder (winter) months, when vitamin D production in the skin declines. This happens because the most generally available source of vitamin D is sunlight. Reduction in skin production of vitamin D due to reduced or no exposure to daily sunlight is accompanied by a decline in blood levels of vitamin D.
Some vitamin D experts suggest adults should supplement with 2,000 IU vitamin D per day (especially during the winter) as a means to maintain more optimal vitamin D status in general, strengthen immune function and help reduce the risk of influenza and its invasion into the lung cavity.
Anyone who's suffered through the flu knows that it's not only potentially dangerous; it can be downright miserable. Ask your doctor to assess your current vitamin D status and discuss the value of vitamin D supplementation, particularly during the flu season. Whatever your strategy, it won't eliminate your risk altogether, but why not do everything you can do naturally to protect yourself and your loved ones?
