This Sleep page brings together products across the following 4 categories: Magnesium Supplements, Ashwagandha Supplements, Melatonin Supplements, Magnesium Glycinate.
These categories are linked together here because they are commonly associated with Sleep. Every category here may not carry the same weight of established research.
Unbox Health independently tests what is inside every product for label accuracy, safety and nutritional composition. Our lab data verifies what a product contains, while the strength of evidence for its potential health benefits may vary.
It is the form most often sold for sleep, mainly because it is gentler on the stomach than cheaper magnesium salts rather than because it acts differently on sleep. The evidence for magnesium and sleep is modest overall. If a deficiency is the reason you sleep badly, correcting it helps. If it is not, the form will not change that.
This is one of the better supported uses for it, since jet lag is a timing problem and melatonin is a timing signal rather than a sedative. Direction of travel and when you take it decide whether it helps or makes things worse. In India melatonin is sold over the counter, which is not the case everywhere.
Less well than most buyers expect. Trials show it shortens the time taken to fall asleep by a modest margin, and it does not keep you asleep. Long standing insomnia usually has a behavioural or medical cause that a supplement does not touch. Anyone sleeping badly for weeks is better served by a doctor than a stronger dose.
The evidence is thin for both and thinner for sleep than the marketing suggests. Magnesium is involved in nerve and muscle function, which is where the claim comes from, but supplementing it in someone who is not short does little. ICMR-NIN sets magnesium as a nutrient requirement rather than a treatment for either.
Melatonin can, particularly at the higher doses commonly sold in India, since the dose that shifts timing is much smaller than what most packs contain. Grogginess is usually a sign the dose is too high rather than that the product is working. Unbox Health publishes tested melatonin content against what each pack declares.
People commonly do, and they work through different routes, so there is no obvious clash at normal amounts. That said, no trial has tested the pairing, and taking two things at once makes it impossible to tell which one did anything. Start with one, give it a fair run, then decide.
For melatonin the honest answer is that long term nightly use has not been well studied, which is different from saying it is unsafe. Nightly reliance also tends to mask a cause worth finding. Anyone on sedatives, blood thinners or blood pressure medication should clear it with a doctor first, and so should anyone pregnant.
Because dose is a formulation choice rather than a regulated one, and higher numbers sell better than accurate ones. Research on circadian timing uses amounts at the low end of that range. More does not mean faster or deeper sleep. Unbox Health publishes tested melatonin content alongside the declared figure for these products.
Often less, and they carry added sugar the tablet does not. Format is a delivery choice rather than a strength guarantee, so the same brand can sell noticeably different amounts across the two. Read the per unit figure rather than the per pack claim, since serving sizes differ between formats.
Usually not. Screen time, caffeine timing, an irregular schedule and alcohol account for most poor sleep in adults, and none of them is fixed by a capsule. A supplement is reasonable once those are genuinely addressed. Unbox Health rates these products on label accuracy, so declared and tested content can be compared before you buy.
