Does vitamin D help with sleep?

An intervention trial found that supplementing veterans with vitamin D (D3) enhanced their sleep duration. Another double-blind clinical experiment found that taking vitamin D supplements (50,000 IU every two weeks for eight weeks) improved sleep duration and quality in adults with sleep disturbances. However, other studies have not shown similar effects of vitamin D on sleep.

Vitamin D is involved with regulating the body's circadian rhythm, or internal clock. It does this by affecting the production of hormones called melatonin and cortisol. Vitamin D helps regulate these hormones' levels throughout the day to bring about healthy sleeping patterns. When there is insufficient vitamin D in the body, it can lead to insomnia. However, when you supplement with vitamin D, this can have the opposite effect and help people who suffer from insomnia get better quality sleep.

There are several theories about why vitamin D might be linked to good sleep. One theory is that it could be because vitamin D stimulates the secretion of insulin from the pancreas which leads to lower blood sugar levels. Lower blood sugar levels mean that you will likely go to sleep more easily and stay asleep longer.

Another possibility is that vitamin D may play a role in producing certain chemicals in the brain that affect how well we sleep. Scientists think that it may do this by acting on cells in the brain that make serotonin.

Can vitamin D give me insomnia?

Vitamin D deficiency can cause a variety of sleep problems, including sleep disturbance, insomnia, and general poor sleep quality. "Vitamin D insufficiency has been linked to various changes in sleep, including less sleeping hours and less deep and restorative sleep," Dr. Hite says.

How does vitamin D affect sleep? The body uses vitamin D to regulate the amount of calcium in the blood. Too much calcium in the blood can lead to nervous system problems. Vitamin D plays a role in regulating the balance of calcium in the body by helping the kidneys remove excess calcium from the body.

People are usually advised to get at least 200 IU per day of vitamin D. However, recent studies have shown that levels above 50 nmol/L (20 ng/ml) are necessary to maintain adequate calcium metabolism. The optimal level has yet to be determined, but some experts believe it may be as high as 100 nmol/L (40 ng/ml).

Sunlight is needed to make vitamin D. But many people limit their exposure to sunlight due to fears of skin cancer. But the risk of developing melanoma, the most serious form of skin cancer, is relatively low for those who avoid the sun entirely or spend a lot of time indoors during adulthood.

Some studies have suggested that individuals who live in regions with little sunshine might benefit from a supplement.

Should vitamin D be taken in the morning or night?

Melatonin, the sleep hormone, is likewise negatively associated to vitamin D. This makes logical since, if we acquire our vitamin D naturally from the sun, we synthesize it during the day. As a result, taking vitamin D tablets in the morning is typically preferable. However, some studies have shown that taking it at night has its advantages too.

Vitamin D is important for health because it regulates the activity of calcium in the body. Therefore, it plays a role in building strong bones and teeth. It also helps the immune system fight off infections.

There are two forms of vitamin D: vitamin D2 and vitamin D3. Only vitamin D3 can be obtained through diet so these days most people are getting their vitamin D from food rather than supplements. However, scientists used to think that you needed more vitamin D when it was dark out. They believed that your body made more of it when it was light out so as to not run out of the nutrient. However, this theory has been proven wrong over time. Today, many experts believe that you need the same amount of vitamin D no matter what time of year it is.

So, the answer to the question "should you take vitamin D in the morning or night?" is both. Ideally, you should take your dose of vitamin D with each meal to keep your body satisfied and avoid taking excess doses of the vitamin.
