Can I Take Vitamin D at Night? – Vitamin D3 before Bed

Can you take vitamin D at night? Absolutely!

Vitamin D, also known as the sunshine vitamin, plays an essential role in maintaining a healthy body. This fat-soluble vitamin supports bone health, promotes a strong immune system, and may lower your cancer risk.

Vitamin D also has surprising impacts on sleep regulation—low vitamin D may even increase your risk of sleep disorders and sleep apnea.

Find out why taking a vitamin D supplement at night can enhance your sleep quality.

Can vitamin D3 help support sleep?

Vitamin D3 is produced in the skin through sun exposure. It’s also found in some food, including fatty fish, egg yolks, and organ meats. However, most food sources contain only small amounts, and it’s unlikely that dietary intake alone supports healthy vitamin D levels.  

Vitamin D supplementation is an easy and convenient way to ensure you are getting enough vitamin D. Research suggests that healthy blood levels of vitamin D can improve sleep duration and overall sleep quality significantly. 

Although the link between vitamin D and sleep hasn’t been fully understood, vitamin D appears to promote the production of melatonin, a pineal hormone that triggers sleepiness and prepares your body for sleep.

In addition, vitamin D is involved in sleep cycle regulation, and low vitamin D levels are linked to an increased risk of sleep apnea and shorter sleep duration.  

How much vitamin D you need depends on many factors, including your vitamin D blood levels, sunlight exposure, medication use, skin tone, and body weight. 

Most healthcare providers recommend a daily dose of 600 IU daily. However, 600 IU of vitamin D may not be enough if you are vitamin D deficient or get little to no sunlight exposure.  

Can you take vitamin D3 at night?

Several studies investigating if taking vitamin D at night supports healthy sleep reported that taking vitamin D significantly improves sleep quality and duration. It also appears that taking vitamin D at night provides the most benefits for supporting restful sleep.

It’s important to note that vitamin D is a fat-soluble nutrient and requires dietary fats and sufficient bile flow for maximum intestinal absorption. To boost vitamin D absorption, it’s best to consume in combination with healthy fat such as olive oil, butter, meat, dairy, MCT oil, or avocado. 

When not to take vitamin D before bed

Vitamin D does promote healthy sleep. However, some individuals appear sensitive to the effects of vitamin D and experience sleep issues if taking vitamin D later in the day. 

Although research isn’t yet conclusive, postmenopausal women and the elderly may be at an increased risk of sleep problems due to taking vitamin D at night. 

If you regularly experience poor sleep, taking vitamin D with a fat-containing meal in the evening may benefit your sleep quality. Listen to your body and adjust the timing of supplementation if sleep disturbances worsen. 

Key takeaways

Taking vitamin D at night can improve sleep quality and prolong sleep duration. To boost vitamin D’s intestinal absorption, it’s best to take it with a meal rich in healthy fat. 

Some people find that taking vitamin D at night can cause sleep disturbances, and taking vitamin D in the morning instead is an excellent alternative to support healthy vitamin D levels without the risk of disrupted sleep.
