What you may not know is that recent research has also shown that adequate vitamin D levels are necessary for optimal immune, brain, nerve, and muscular function and control of genes that can influence our tendency toward certain diseases. Research in these areas is still evolving.
Can You be Vitamin D Deficient?
How does someone become vitamin D deficient? Remember the age-old recommendation to get your 15 minutes of daily sunshine? Well, as it turns out, that may not be enough. A study of young Hawaiian skateboarders and surfers found that over 50% of them had vitamin D levels lower than average. Slathering on sunscreen could be an issue in blocking adequate absorption. What was really interesting was that the vitamin D levels of these tropical sun-bathing folks were compared with the levels among Wisconsin residents who were taking vitamin D supplements and who weren’t riding waves or boogying down the sidewalk on their boards. Guess who had better levels? Yep, it was the pale-skinned Midwesterners. Apparently outdoor training and recreation wasn’t cutting it for maintaining adequate vitamin D levels.
What’s The Optimum Level?
Can you have too much? Evidence suggests that levels above 50 ng/mL may pose an increased cancer risk. But that’s not the problem for most of the population. Not having enough D on board is the critical issue.
The good news is that emerging information about vitamin D’s potential has prompted excellent new research studies. For instance, the National Institutes of Health has initiated a study to include 20,000 men and women over 60 years old to study whether 2,000 IU of vitamin D, omega-3 fatty acids from fish oil, or placebo will lower the risk of heart disease.
5 Ways To Beat Vitamin D Deficiency
1. Get Your Vitamin D Level Checked
This is especially important for those people who are getting little sun, are at risk for osteoporosis, may have inadequate dietary intake, and are either taking no vitamin supplements or
2. Get Your Doctor’s Advice
Because there is controversy surrounding the IOM report regarding what is a normal D level and supplement intake, you need to talk with your medical professional about your individual situation. Your gender, age, level of physical activity, nutrition intake, bone status, osteoporosis risk, and sun exposure are all factors that must be considered. Then add to this your D level and you can have a comprehensive discussion about next steps to optimize your D status.
3. Add Up Your Daily D Intake
Just for grins, whip out your supplements and add up how much D you’re actually consuming. Multivitamins contain D at varying levels, while calcium supplements are usually fortified with D. Check out how much D you’re consuming from foods sources including fortified dairy and cereals. This will help you monitor your total intake. And it will be helpful to share this information with your medical team when you’re deciding how much D you need on a daily basis.
4. Soak Up A Few Rays
Even though we
5. Eat D-licious Foods
You saw the laundry list of natural food sources for vitamin D. If you eat salmon, try to get the wild (not farmed) type, as it has fewer contaminants. I’m increasing my egg consumption and integrating more mushrooms into my daily salads and side dishes.
