Vitamin D: Natural Flu Prevention
It's important to remember that your immune system is your primary line of defense against any virus, so keeping your immune function high should be at the top of your list if you want to avoid influenza or other flu-like illness.
Optimize Your Vitamin D levels!
Optimizing your vitamin D levels is one of the absolute BEST strategies for avoiding infections of ALL kinds, and vitamin D deficiency may actually be the true culprit behind the seasonality of the flu – not the flu virus itself. This is probably the single most important and least expensive action you can take. Regularly monitor your vitamin D levels to confirm your levels are within the therapeutic range of 50-70 ng/ml. Ideally, you'll want to get all your vitamin D from sun exposure or a tanning bed, but as a last resort you can take an oral vitamin D3 supplement.
