Story at-a-glance -

  • Children taking 1,200 IU’s of vitamin D3 per day were shown to be 42 percent less likely to contract influenza, compared to children taking a placebo
  • Five Cochrane Database Reviews issued between 2006 and 2010—which are the ‘gold standard’ in terms of medical research reviews—have decimated the popular claim that flu vaccinations are the best and most effective flu prevention strategy available
  • The important factor when it comes to vitamin D is your serum level, which should ideally be between 50-70 ng/ml year-round. Sun exposure is the preferred method for optimizing vitamin D levels, as your skin also synthesizes vitamin D3 sulfate, which appears to play an important role in maintaining healthy cholesterol levels and heart health
  • Vitamin D supplement dosages have recently been revised based on the latest research data. Most adults need about 8,000 IU's of vitamin D a day to achieve serum levels above 40 ng/ml, which is still just below the minimum recommended serum level of 50 ng/ml. Children need about 35 IU’s per pound of body weight
