Can I Overdose on Vitamin D?
I think I have seasonal affective disorder and I’ve been taking a lot of Vitamin D. Is it possible to overdose? A lot of people are taking Vitamin D supplements right now and a lot of people ask me about this. So you can definitely take too much. And you should not just treat it like Vitamin C. Vitamin D is also unique in that very few foods contain it and you basically get 90 percent of your Vitamin D by your own skin absorbing sunlight, converting cholesterol into Vitamin D. And your body should be able to make plenty. It wasn’t until the industrial revolution that people started getting rickets. Kids started to be born with bowed legs. In London, where there were tall buildings and people were primarily living indoors, they didn’t know how to prevent it until someone noticed that if you give these kids cod liver oil, they don’t get rickets. No one knew why until about 100 hundred years ago, when they isolated this compound Vitamin D. There are also receptors for Vitamin D in the brain that works in ways that we don’t quite understand, but it does seem to be related to mood and seasonal affective disorder. Not necessarily the only explanation. People are also less likely to go outside, less likely to exercise, less likely to do all the things that keep you healthy and happy throughout the year because it’s dark and freezing and you just want to go home and sleep and watch Netflix and chill as they say. You can Netflix and chill alone. When you take a Vitamin D supplement, the level of calcium in your blood increases. If that gets too high or stays high for too long, that can accumulate in your kidneys and form kidney stones. You can’t cure everything with Vitamin D. You can’t cure everything with your diet. You can’t cure everything by joining a zumba class. Hell, I don’t even know what Zumba is. It’s a fitness dance class. Something about it just creeps me out. Netflix and chill? How about nuts, flax, and kale. If you have an interesting health question, ideally one where you’re not actively bleeding, then write to us and we’ll do our best to help you out.
