Vitamin D: Winter check-up to keep levels optimal

snowHow is it possible that a year has passed since I wrote about winter vitamin D levels while sitting poolside in the Dominican Republic, tropical drink in hand? With time flying by, I understand when women tell me they’ve had their level checked “just a few months ago” but when they stop and think more carefully, it’s been several years.

This is one reason I remind you yearly about the importance of maintaining your vitamin D levels during the winter.

Have you had your vitamin D levels tested recently?

If not, do so now!  I’ve summer up the reasons optimal vitamin D levels are so important in the box below.

How much vitamin D do you need?

While a blood level of 40 ng/mL is acceptable, a more optimal blood level of vitamin D is 50 to 60 ng/mL as measured by the 25(OH)D blood test.

Winter is a “vitamin D desert” up here in the northern latitudes, and unless you head south, below Atlanta to be exact, you will need to take vitamin D supplements to maintain an optimal blood level of vitamin D throughout the winter.

How much vitamin D to take varies greatly

On average we can use about 3,000 to 4,000 IU of vitamin D per day and taking this amount during winter months generally provides for at least a minimal protective level (which is around 32 ng/mL). However, many individuals need more than this, and a few who absorb vitamin D better might be able to get by on 1,000 or 2,000 IU per day.

How to test your vitamin D at home

Assuring that you and your family have adequate vitamin D levels is the simplest thing you can to do prevent disease and enhance health. Even winter colds and flu are much less common among those with adequate vitamin D on board!
