These 7 Vitamins and Natural Supplements Support Better Sleep
At a Glance
- $1,000 could be spent yearly by many adults to improve sleep.
- 7-8 hours of sleep is the recommended nightly duration.
- Seven natural supplements may help boost sleep quality.
Quality sleep is essential for health, yet many people struggle to reach the recommended 7-8 hours per night. Stress, erratic schedules, and chronic insomnia can make rest feel out of reach. A recent survey found that more than half of U.S. adults are willing to spend close to $1,000 a year hoping to sleep better.
How We Chose These Supplements
The list below was built from a mix of personal experience and market research. Every supplement has at least one supporting scientific study and is generally considered safe. The FDA does not regulate supplements, so safety and efficacy can vary, but the options chosen here have a solid research base.
Magnesium
Magnesium is vital for brain and muscle function, blood pressure regulation, and bone health. It also helps control the body’s circadian rhythm.
- Benefits: Studies suggest magnesium can aid insomnia by regulating circadian cues. Low magnesium levels are linked to poor sleep.
- Dosage: Typical supplemental doses range from 200 to 400 mg per day.
- Side effects: Over-dosing can cause nausea, cramps, and diarrhea.
- When to consider: If you’re not meeting the daily magnesium intake, this supplement may improve rest.
Melatonin
Melatonin is a hormone produced by the brain at night, signaling that it’s time to sleep. Synthetic melatonin mimics this hormone.
- Benefits: It can help you fall asleep faster and may assist with jet lag and certain sleep disorders such as delayed sleep-wake phase disorder.
- Side effects: Headaches, upset stomach, daytime drowsiness, and vivid dreams are possible.
- Dosage: Common doses range from 0.5 mg to 5 mg taken 30-60 minutes before bedtime.
Gamma-Aminobutyric Acid (GABA)
GABA is an amino-acid neurotransmitter that calms the nervous system.

- Benefits: A study found that 300 mg of GABA daily improved sleep quality in 40 insomnia patients after four weeks.
- Safety: More research is needed. Pregnant or breastfeeding individuals should consult a doctor.
- Precautions: Avoid if you are on medications for high blood pressure or other sedatives.
L-Theanine
L-Theanine is an amino acid found in tea leaves and some mushrooms.
- Benefits: It promotes calmness and reduces anxiety. A review indicates it is safe and does not cause grogginess.
- Interaction: It can lower blood pressure, so discuss with a doctor if you’re on hypertension medication.
- Caution: Do not mix with sedatives.
Valerian Root
Valerian root is a herb from a white flower native to Europe and Asia.
- Benefits: Research suggests it may be especially helpful for menopausal insomnia. It is low-risk and cost-effective.
- Usage: Can be brewed into tea or taken as a supplement.
- Combination: For a relaxing bedtime tea, pair valerian root with chamomile.
Chamomile
Chamomile is a flower commonly used to induce sleep and calm anxiety.
- Benefits: Flavonoids in chamomile bind to GABA-A receptors, promoting relaxation.
- How to use: Tea is cheaper than supplements.
- Safety: Generally safe, but those with ragweed allergies should avoid.
Vitamin D
Vitamin D is essential for many brain tissues, especially those involved in sleep regulation.
- Benefits: Low vitamin D levels correlate with poor sleep. Supplementation is recommended if you’re deficient.
- When not to use: If you’re not deficient, taking vitamin D specifically for sleep is not advised.
Safety and Precautions
All supplements are considered safe when taken within recommended limits, but they can interact with medications or have side effects.
- Pregnancy and breastfeeding: Discuss any supplement with a healthcare provider.
- Medication interactions: Some supplements can lower blood pressure or interact with sedatives.
- Deficiency first: The most effective strategy is to address nutrient deficiencies. If your diet lacks magnesium or vitamin D, these supplements may improve sleep.
