The Harvard School of Public Health suggests an estimated 1 billion people worldwide have low vitamin D levels, with deficiencies noted across all age and ethnic groups.
You are at risk of missing out on vitamin D from natural sun exposure if you spend most of your time indoors, use topical sunscreens or wear long clothing for religious reasons.
This study from Health Impact News supports an important role for vitamin D in prevention of common respiratory infections, such as colds and the flu. Individuals with common lung diseases, such as asthma or emphysema, may be particularly susceptible to respiratory infections from vitamin D deficiency. Another study, done in Japan, indicated schoolchildren taking 1,200 units of vitamin D per day during winter reduced their risk of contracting the flu by about 40 percent.
Here is a list of vitamin D deficiency symptoms that most people ignore from Healthyway.com.
If for whatever reason you cannot get outdoors, or not frequently enough to receive sufficient UV exposure,consider taking an oral vitamin D3 supplement along with vitamin K2 and magnesium.
I take an excellent Vitamin D3 supplement that provides 2000 IUs of vitamin D3 to battle the effects of Vitamin D deficiency to support my immune system, bone health and mood. It’s the same vitamin D my body produces when exposed to the Sun without exposure to, harmful UV rays.
This combined with my Peak Performance = Optimal health!
Even if you are in good health, I encourage you to have your level tested twice a year by your primary health care provider and think about taking a vitamin D supplement like I do.
