Do You Have a Vitamin D Deficiency?

There could be a deficiency in your diet: Harvard University researchers discovered that most people have blood levels of vitamin D that are far below optimal.

US scientists say that a daily dose of 1,000 international units (25 micrograms) is needed to maintain health, and to achieve the lowest risk of bone fractures, periodontal disease and colon cancer. That's about 20 micrograms more than the average man's current intake.

Although milk is an obvious source of vitamin D, it contains just three micrograms per 230ml glass. Boost your intake with a vitamin D supplement.
