A guide outlines seven vitamins and natural supplements — including magnesium, melatonin and vitamin D — that studies and market research associate with improved sleep, and it notes possible side effects, interactions and that supplements are not regulated like prescription drugs.

Many people find it hard to get seven to eight hours of sleep consistently. The article reviews seven vitamins and natural supplements that are commonly used to support sleep. It reports that some studies show potential benefits for specific supplements, while evidence strength varies. The piece also emphasizes possible side effects, interactions with medications, and that supplements are not regulated like prescription drugs. Key facts: - The seven supplements discussed are magnesium, melatonin, GABA, L‑theanine, valerian root, chamomile and vitamin D. - Some research links low magnesium or vitamin D levels to poorer sleep, and studies have found sleep benefits for melatonin, GABA and other agents in certain groups. - Commonly reported side effects include headaches or daytime tiredness with melatonin, and nausea, cramps or diarrhea with high magnesium doses. - Interactions and cautions are noted: for example, L‑theanine may affect blood pressure and some supplements can interact with sedative or blood‑pressure medications. - Supplements are not regulated by the FDA in the same way as drugs, so quality, dosing and labeling can vary. Summary: The article reports that several vitamins and natural supplements may help support the body’s natural sleep processes for some people, but the level of scientific support differs by supplement and by population. It also reports that side effects and drug interactions are possible and that supplement quality and dosing can vary because of limited regulation, and that medical consultation is advised before starting supplements.
