Why vitamin D deficiency is ruining your sleep

We usually think of vitamin D as the “sunlight vitamin.” And while vitamin D is critical to our bodies, it is ALSO critical to your sleep. Some of the latest research suggests that vitamin D influences both your sleep quality AND and your sleep quantity.

Vitamin D is a steroid hormone that helps control how cells and organs function. It’s produced in the kidneys and controls blood calcium levels and the immune system. Adequate levels of vitamin D contributes to strong bones and teeth, prevents, the body from breaking down, and supports the immune system, nervous system, and muscles.

Studies show that adults and children with vitamin D deficiency are more likely to have things like delayed bedtimes, less time asleep each night, low quality sleep, and frequent nighttime wakings. They are also at a higher risk for developing a sleep disorder.

So join Dr. Michael Breus as he explains how vitamin D actually works in your body, and why it's one of the essential vitamins you need to get your best sleep.

  1. In my case, taking both vitamin D and dairy on a daily basis ruined my sleep because it was causing pain in my urinary system (cause : urinary crystals – calcium phosphate crystals). It took months for the pain to stop and now when I take vit D, I get pain in the same region.

    1. Like I said, I mixed vit D3 with dairy! You can use butter cause even if the calcium is highly bioavailable, there’s only low amounts of calcium in it. But I would definitely avoid yogurt and cheese and even milk if you’re gonna take Vit D, especially if it’s high vit D3 intake. For example, if you don’t eat dairy, sure, go for 5-10k IUs of vit D3 during winter. I wouldn’t do that mixed with dairy though.@@Bulletproofyourhealth

  2. I stopped taking vitamin D because I could not sleep. I will try it again after talking to my Dr. 😊

    1. Try taking 1000IU of D2. It’s lower absorption, but it’s better slow than nothing.

  3. Why do some research says that sun exposure is best in midday between 10am to 3pm? Which is true?

  4. Every since I elevated my Vitamin D my sleep has for the first time in years been great. I also only get up about once a night at the most to use the restroom. I have been begging for years the ability to sleep well at night.
