The Chicago Blackhawks are the first vitamin D team in modern professional sports history.

According to my sources, the Chicago Blackhawk team physicians began diagnosing and treating vitamin D deficiency in all Blackhawk players about 18 months ago. Apparently, most players are on 5,000 IU per day.

After many losing seasons, last year the Blackhawks came out of nowhere to get to the Western conference finals. This year they are playing even better.

According to my sources, improved athletic performance is only one of the benefits for the Blackhawk players. The other is a reduction in the number and severity of colds and flu and a reduction in the number and severity of repetitive use injuries.

Six months ago, Runner’s World published a story on vitamin D and physical performance.

A year ago, the flagship journal of the American College of Sports Medicine was the first journal to publish the theory that vitamin D would improve athletic performance.

However, readers of this newsletter first learned about it in the March 2007 edition of our Vitamin D Newsletter, entitled Peak Athletic Performance and Vitamin D.

I can only hope that, if the Blackhawks win the Stanley Cup this year, other teams, from high school to professional, may start paying attention to the vitamin D status of their players. That would be a big boost to the Council’s goal of educating the world about the importance of vitamin D.
