Summer and Vitamin D

First off, I want to give a shout out to three Overdrivers, Jacky, Vanessa, and Dave, who went and attended the CrossFit Level 1 Certification course in Vancouver this past weekend. They all had an amazing time, learned lots, and are now much more knowledgeable and bring added value to Overdrive as students, friends, and workout buddies to help make all of us better Crossfitters! Way to go guys! Very proud of you!

Vitamin D

(from CF Verve)

Summer is here and the rays are abundant!  Despite our 300 days of annual sunshine, 50% of the population has a vitamin D deficiency? Now consider what our vitamin D levels would look like seasonally – especially mid-winter, when the last thing you want to do is go outside and expose your skin to the elements.

Inadequate levels of vitamin D are linked to decreased athletic performance, poor insulin sensativity, low testosterone levels, and inflammation. People with low levels of vitamin D are also at an increased risk for metabolic syndrome.  None of these pathologies appeal to us, so we have a couple of recommendations for you.

First, check with your physician to see if vitamin D supplementation is right for you. This can be done with a simple blood panel with an additional vitamin D screening (which will be required for your next food challenge).  Second, since it’s summer and the weather has been fantastic, get your D the easy way – expose 40% of your skin to direct sunlight for 10 to 20 minutes daily. This will provide you with adequate levels and improve your sunny glow.  Lastly, if you’re stuck in an office chair with no hopes of getting into the sun – you can supplement with a 4,000 – 6,000 IU  dosage daily.
