Does Vitamin B6 Help You Sleep?

Vitamin B6 helps keep our nervous systems and immune systems healthy. And some people take B6 supplements to try and remember their dreams! Plus, vitamin B6 might help you sleep better, especially if you have trouble falling asleep at night.

Read on to learn what vitamin B6 is, what foods to find it in, and how it can help improve your sleep quality. 

What Is Vitamin B6?

Vitamin B6 is also called pyridoxine. It is a vitamin that helps our bodies absorb food (especially sugars and fats) to give us energy. It also helps with developing our brains and skin! Vitamin B6 is a key part of regulating the production of amino acids and hormones in our bodies. As a result, B6 and other B vitamins have many health benefits.

Foods with Vitamin B6

Vitamin B6 is found in proteins like tuna, salmon, chicken, and organ meat. You can also find it in dark leafy greens, chickpeas, bananas, and other non-citrus fruits. Some breakfast cereals are also fortified with vitamins, which can make it easier to enjoy the benefits of vitamin B6.

Symptoms of Vitamin B6 Deficiency

B6 deficiency is a serious issue. If you notice you have inflamed skin or a greasy, scaly rash; numb or prickly hands and feet; a sore or dry tongue; or are more confused and irritable than usual you might want to reach out to your healthcare provider. These may be symptoms of a vitamin B6 deficiency. Anemia and sleep disturbances might also suggest you have low levels of vitamin B6.

Vitamin B6 Benefits

Vitamin B6 has tons of great health benefits. It can improve your mood, decrease symptoms of sleep disorders, and boost immune function. It might even help prevent morning sickness! Read on below to learn the specifics.

May Regulate Mood and Decrease Depression

B6 can help regulate our moods by stimulating serotonin and dopamine production. These hormones play an important role in mood regulation, and increasing production with B6 might help you feel happier. B6 can also help you sleep better, and depression and sleep are very closely linked. Improving your mood can improve your sleep, and vice versa.

Increased Brain Function

The protein homocysteine can increase your risk of dementia, Alzheimer’s and general cognitive decline, especially in older adults. Vitamin B6 lowers levels of homocysteine in the body. So an unintended but welcome side effect of taking B6 is that it can improve your brain function. If you’re worried about memory loss, make sure to get plenty of vitamin B6 in your diet.

Boosted Melatonin and Serotonin Production

Vitamin B6 helps produce serotonin, a neurotransmitter that can regulate our moods. If you are feeling depressed, increasing your vitamin B6 intake might help relieve your symptoms. Additionally, B6 helps us produce melatonin, the neurotransmitter that regulates our sleep-wake cycle. If you struggle with lack of sleep, low melatonin production might be an issue. Increasing your B6 intake (or taking a B complex vitamin that includes vitamin B1 through vitamin B12) might help you fall asleep more easily.

Helps You Remember Your Dreams

Researchers from the University of Adelaide discovered that vitamin B6 might help you remember your dreams. In a study published in the Journal of Perceptual and Motor Skills, researchers split 100 participants aged 18 to 40 into three groups. One group of participants took a supplement containing 240 mg of vitamin B6 before bed each night. A second group took a supplement of B complex that contained vitamin B6 and other B vitamins. The third and final group took a placebo.

Results suggest a link between vitamin B6 and the ability to remember dreams. However, those who took vitamin B6 did not experience vivid, bizarre, or colorful dreams. It also didn’t significantly affect their sleep patterns.

Being unable to remember dreams could be a bad sign, especially if you experience tiredness throughout the day. If that sounds like you, you might want to increase your vitamin B6 intake.

Does Vitamin B6 Help You Sleep?

Yes, vitamin B6 can help you sleep by increasing melatonin production. Melatonin helps you fall asleep at night, which can help prevent sleep deprivation. 

How Much Vitamin B6 Should I Take?

Clinical trials indicate that taking too much B6 can have negative side effects. According to the National Institutes of Health (NIH), adults aged 19-50 years should consume 1.3 mg of vitamin B6 per day. Older adults should consume a little more, and children and teens a little less. B6 is water-soluble, so you can take a supplement containing up to 100 mg of B6 per day and will excrete the rest. If you plan to start taking a B6 supplement to help you sleep, be sure to follow your doctor’s medical advice.
