Compare every Melatonin product across UK retailers on Suppio, ranked by true value - price per active dose, not pack size. Prices refreshed daily.
Hormone regulating sleep-wake cycles
We rank Melatonin by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
Melatonin is a hormone, which is a chemical messenger in the body, that regulates your sleep-wake cycles. It tells your brain when it is time to feel sleepy and when it is time to wake up.
It is primarily used to help people fall asleep faster or to manage jet lag. By mimicking the body's natural signals, it helps reset the internal clock when sleep patterns are disrupted.
To create the supplement, the substance is produced through a chemical synthesis process in a laboratory. Once the pure powder is created, it is measured and packed into capsules or pressed into tablets for sale.
This ingredient is generally mid-range in price. This is because the chemical synthesis required to produce it is more complex than simple vitamin extraction, but there is enough global supply and competition to keep costs from becoming premium.
