We have been lucky this January to have so many sunny days, but are we still getting enough vitamin D? I know that most days I am working inside and only see the sun when I am taking care of my chickens in the morning. If we don’t get enough sun and our vitamin D levels go down, we can start suffering from the winter grumpies, or seasonal affective disorder, as it is technically known.
I often encourage my patients to take a low dose of vitamin D during the winter or all year long, especially if they are taking a calcium supplement. I am not necessarily a fan of the higher doses such as 5000 IU once a day, since too much of a good thing isn’t always a good thing. Vitamin D is actually a hormone that regulates calcium metabolism, and as with hormone replacement therapy, there is a normal range for our bodies. Unless someone is deficient, the higher doses might actually reduce some of the vitamin D benefits. Additionally, sometimes we need to dig deeper. If someone is vitamin D deficient, it can be due to excessive inflammation in the body, and this may need to be addressed more than the vitamin D levels
Adequate vitamin D is associated with many health benefits including stronger bones, lower rates of influenza, reduced blood pressure, and reduced breast and colon cancer risk, but some of the benefits go away if people take too much. Therefore, I have been encouraging people who don’t know their vitamin D levels to stick with doses around 1000 IU. One study demonstrated that just 800 IU a day slightly reduced mortality due to any cause in elderly people, mainly women.
So if you are dealing with the wintertime blues, considering adding a little vitamin D to your routine, but remember don’t overdo it.
And get some sun when you can!
