The best sleep supplements to help you nod off, trialled by a panel of 160 poor sleepers
We wanted to find out if sleep supplements genuinely work – here's the verdict
Tested by Kim HawleyHealth and Fitness Tester
With never-ending to-do lists, work and family stresses, sky-high screen time and sometimes poor sleep hygiene, it’s no wonder we aren’t getting the rest we need and deserve. In fact, 73% of GH readers say they consistently struggle with their sleep.
As people look to find solutions, the best sleep supplements are becoming increasingly popular, with a whole host of options lining the shelves. We’re not taking about sleeping tablets or sedatives, which are prescribed by a GP, but nutritional supplements made with natural ingredients to aid relaxation, ease stress and help regulate the body’s circadian rhythm (your internal body clock).
But do they actually work? We decided to put them to the test with our reader panel.

With so much choice out there and some brands making bold claims, it's hard to know where to start. So, our Good Housekeeping Institute experts recruited a panel of 160 poor sleepers to put a range of market-leading supplements to the test (and track their sleep patterns throughout the trial) before giving us detailed feedback.
We also asked Megan Foulsham, senior nutritionist, and Georgia Chilton, senior nutrition manager at Calo, to analyse the ingredients and nutritional make-up and give us their verdict.
Who should take a sleep supplement?
“If you’ve tried optimising your sleep environment, maintaining a consistent schedule and reducing stress, but still struggle to fall or stay asleep, it may be worth considering a product to help support your sleep cycle,” says Heeral Patel, health and science editor at Holland and Barrett.
“There are a number of different options available that may gently encourage relaxation, reduce the time it takes to fall asleep and improve the quality of your rest without leaving you feeling groggy,” she adds.
Patel warns that natural sleep remedies aren’t for everyone, including children and anyone who is pregnant or breastfeeding. Consider your individual circumstances – if you have any underlying health conditions or are on medication, she advises speaking to doctor before taking any sleep supplements. “If you’re taking antidepressants, blood thinners or sedatives, supplements and herbal remedies could interact with them.” she says.

From collagen to protein powders, certified B Corp brand Wild Nutrition is known for its naturally sourced supplements. Its magnesium capsules are designed to reduce tiredness and fatigue and claim to improve sleep duration by up to 42 minutes.
The brand describes the ingredients as ‘food grown’ and says this makes the supplement more bioavailable, enabling the body to absorb it more easily and use it more efficiently. The supplements are also free from synthetic ingredients, binders and fillers.
They made a good impression on our testers, with many experiencing improvements to their sleep patterns. “I certainly feel more refreshed when I wake up and I felt less tired and more energetic while taking the capsules,” said one tester. Another told us: “My sleep score was '58' before taking them and '75' after, so there’s a definite difference.”
As with all supplements, it's about finding what works for you and your body. That’s why Wild Nutrition offers a 100% happiness guarantee – if you don’t notice any benefits after 30 days, you can get your money back.

These Holland and Barrett capsules contain DailyZz™ (a clinically researched botanical blend, said to improve sleep quality and next-day cognitive function), 5-HTP and magnesium, along with herbal ingredients like green tea extract and Montmorency cherry extract, which may increase melatonin levels. According to the brand, the ingredients “work in harmony with your body to help you relax, enjoy a restful night’s sleep and wake up refreshed.”
Several testers noted improvements to their sleep after adding these to their routine, with one saying, “I fell asleep faster and woke up feeling a lot more refreshed.” Another told us: “I would definitely recommend this product, I had no side effects and felt more relaxed in general.” They also found the capsules easy to take and appreciated the clear instructions.
The product also received the nutritionists’ seal of approval; however, they noted that the capsules contain magnesium oxide, which may not be as bioavailable (easy to absorb) and therefore as beneficial as other forms like magnesium glycinate.

This supplement from popular brand Heights contains just one simple ingredient: magnesium glycinate. According to Chilton and Foulsham, it’s the most absorbable magnesium compound available, which means your body can put it to best use. They also point out that, compared with other forms of magnesium like citrate or oxide, it’s less likely to cause gastrointestinal issues such as diarrhoea and bloating.
Our panel found these supplements extremely convenient to use – the slim, lightweight box is ideal for travel, and you don’t need to take the capsules with a meal. One tester would have preferred if they were a bit smaller, but it wasn’t a major issue.
What about performance? While some panel members didn’t notice any improvements to their sleep, a number of testers – who tracked their rest with a device – found they enjoyed more deep sleep and REM sleep when taking the supplement. “My overall sleep score started to improve after a few days,” commented one, while another said: “I felt more alert, rested and less irritable the next day.”
Note, though magnesium glycinate is a more tolerable form of the mineral, it can still cause GI woes, with two out of 10 panellists experiencing mild issues.
These supplements are only available on subscription but you can cancel online at any time and there's a 30-day money-back guarantee.

These nootropic capsules are Informed Sport certified, which means they've been rigorously tested by a third party and are free from contaminants. The blend, which has been designed to support runners and athletes looking for better rest and recovery, features an array of research-backed natural ingredients, such as KSM-66 ashwagandha, Montmorency cherry and L-theanine.
The supplements are used by elite athletes, including triathlete Beth Potter and marathon runner Charlotte Perdue, but what did our panel think? Well, they earned rave reviews from some testers, with one telling us: “I'm no longer lying wide away for an hour before falling asleep, and I also find it easier to wake up because I’m well rested.” Another tester told us they'd already ordered another box and would definitely continue using them. For others, however, there were no major changes or improvements to their rest.
Everyone liked the sleek packaging and clear information label, but some found the capsules quite large and tricky to swallow.

B Corp brand, Form, is best known for its sports nutrition products, but its range of nootropic supplements are also worth considering. The ZZZZs blend includes 5-HTP and amino acids L-Glycine and L-Theanine, along with a dose of magnesium, zinc and BioPerine, a form of black pepper extract, which is shown to help absorb nutrients faster.
Foulsham notes that L-Theanine and 5-HTP work in tandem to support serotonin and melatonin production and may reduce anxiety and help you feel calmer. She also says the combination of magnesium and L-Glycine aids muscle relaxation and can encourage a deeper, more restorative sleep.
What about our panel? Everyone liked the recyclable glass packaging and praised the clear, detailed information on the product itself and via the Form website. One tester told us their REM, core and deep sleep had all improved since taking the product and they would continue to use it. Another tested noted a small improvement to their sleep score during the trial period and said they were able to drift off faster. Some panellists didn’t experience any notable improvements, though.
Key specifications
| Key ingredients | Magnesium citrate, L-Glycine, 5-HTP, L-Theanine, Zinc, Bioperine |

As the name suggests, Health & Her creates supplements with women in mind. This product, formulated by nutritionists, contains a carefully considered blend of botanicals, amino acids and vitamins to help you drift off. The multi-nutrient supplement is designed to support sleep, nerve function, hormone levels and blood glucose levels.
Panel members liked that there’s just one, easy-to-swallow tablet to get down each night and appreciated the informative packaging, with detailed benefits on each ingredient. With your purchase, you also get free access to the user-friendly Health & Her app, where you can find a host of holistic health advice and support.
Some testers found the supplements made a significant difference to their snoozing, with one telling us: “It really helps me fall asleep faster.” Another panellist, who was concerned about side effects, said it didn’t upset their digestion or routine.
The ingredients received a thumbs up from our nutritionists, but they noted that magnesium glycinate, known to support sleep, would have been preferable to magnesium citrate for easier digestion.

Another magnesium supplement, this one from female-focused brand Free Soul, these feature three types of magnesium – bisglycinate, citrate and malate – providing 103% of your daily intake along with turmeric root extract. The brand suggests taking it in the evening to promote restful sleep, after exercise to boost recovery, or in the morning to aid digestion and support your natural energy levels.
Foulsham gave the magnesium complex a thumbs up for muscle relaxation and stress relief, and liked the addition of turmeric for its calming and anti-inflammatory properties. “It’s best for light sleepers, people with stress-related issues or those avoiding stronger sleep aids,” she told us. Note that the tablets contain bulking agents, which could cause digestive discomfort for some.
In terms of performance, several testers noted improvements to their sleep scores, with more time spent in deep and REM sleep after taking the supplement. “I’ve tested other sleep aids, and this has been the most effective, without the groggy hungover feeling the next day,” commented one panellist. Most found the pills easy to swallow, and they liked sleek, informative packaging.
Key specifications
| Key ingredients | Magnesium bisglycinate, magnesium citrate, magnesium malate, turmeric root extract, black pepper extract |

| Recommended dose | One to three tablets per day |

Formulated with magnesium, and L-theanine, this blend also contains herbal and plant extracts and a dose of vitamin B6 and zinc. The goal? “To help you drift off to the land of nod by supporting melatonin product, promoting relaxation and helping to balance psychological function,” according to the brand.
Our experts rated the addition of L-theanine and Montmorency cherry, which are thought to directly promote relaxation and support relaxation. However, like some of the options above, it contains magnesium citrate rather than magnesium glycinate, which is easier on the stomach.
Still, it earned favourable reviews from a number of testers, who said they would continue taking it after the trial. “My sleep very much improved, whether it was down to placebo or not,” said one panellist, while another told us: “I noticed an improvement to my Oura Ring sleep scores, with more time in deep and REM sleep.” On the flip side, a few testers said they saw no improvements to their sleep at all.
The small capsules were easy to swallow, and the bottle itself was portable and travel friendly.
Key specifications

This pre-sleep gummy from Nourished – known for its vegan, sugar-free supplements in sweet form – features a potent combination of natural ingredients, including ashwagandha, 5-HTP and tart cherry, plus your daily dose of vitamin D3 and zinc. The brand says all its products are freshly made to order to ensure the nutrients retain their power and efficacy.
Many testers enjoyed the gummy format, noting that it was “more fun and straightforward” to take than a tablet or liquid. They found the accompanying leaflet, with gave information about each ingredient, useful and liked that the brand didn’t make any exaggerated claims about the potential benefits.
Results were varied – some testers weren’t able to pinpoint any changes to their sleep quality, while others did see some improvements. “I noticed that the duration of my sleep was consistently higher after taking the supplement,” one tester commented. Another told us: “I felt more refreshed in the morning, like I had really good, uninterrupted sleep.”
Our experts approved of the natural sleep-boosting ingredients but noted that maltitol syrup can cause gastrointestinal upset. On the plus side, the packaging is entirely plastic-free and compostable.
Key specifications
| Key ingredients | Ashwagandha extract, 5-HTP, vitamin D3, zinc, tart cherry |

If you fancy a soothing drink to cosy up with before bed, let us introduce you to Ancient & Brave’s citrus nighttime powder. It blends magnesium, choline (said to support the circadian rhythm) L-glycine (an amino acid that can help lower the body’s core temperature) and myo-inositol (an adaptogen thought to support the nervous system balance) with ginger root, vitamin C and zinc. Simply add a spoonful to some water, sip and prepare for a peaceful slumber.
“It’s a really nice drink to incorporate into your nightly routine if you don’t need to use the toilet a lot at night,” said one tester, who described the flavour as lovely. It didn’t go down so well with everyone, though – some found the consistency grainy, and they would have appreciated a scoop for measuring out the appropriate amount.
Reviews were also mixed when it came to performance. One panellist noticed an improvement to their deep sleep during the trial period, while another said: “I’m not sure if it made my sleep better but it was a relaxing end to the day.”
If you travel a lot and need some assistance nodding off, the brand also offers handy travel-friendly sachets.
Key specifications
| Key ingredients | L-glycine, magnesium citrate, ginger root, myo-inositol, choline, zinc, vitamin C |
|---|---|
| Recommended dose | Add 6g of power to 250ml cold or warm water |
Score: 70/100
There are no fillers, additives or artificial flavours here – just a blend of natural ingredients: ashwagandha, reishi mushroom and chamomile with passionflower, nutmeg and Seagreens®. The standard dose is two capsules, but you can take between one and four a night, depending on what works for your body.
Our experts approved of the no-nasties ingredients list, noting that the blend doesn’t contain any additional vitamins or minerals. This makes it a good choice if you’re already taking other supplements and don’t want to overdo it.
Some testers found it worked a dream, with one telling us: “I was less restless, and my sleep was less disturbed by dreams.” Another tester said their sleep score improved according to their Whoop band. Others, however, said they barely noticed any difference – an important reminder that what works for one person might not be right for somebody else.
The brand gets some brownie points for its sustainability efforts; products are made in the UK, the packaging is fully recyclable and plastic-free, and a proportion of the profits supports rhino conversation through the Council of Contributors.
Key specifications
| Key ingredients | Iodine, ashwagandha root, passionflower herb, reishi dual extract, German chamomile flowers, Nutmeg |
|---|---|
| Recommended dose | Between one - four capsules nightly |
How we test sleep supplements
The Good Housekeeping Institute experts recruited 160 panel members to trial a range of sleep supplements over the period of a few weeks. We asked them to consider ease of use, noting if the product was easy to dispense and consume, whether in tablet, gummy, powder or spray form.
Crucially, they also fed back on performance, highlighting any improvements in sleep quantity and quality after taking the supplement as instructed. They measured these improvements using a sleep tracker, whether it was a fitness watch, smart ring or their phone.
We also asked Foulsham and Chilton to assess each product, providing feedback on ingredients and checking they aligned with the brand's claims.
Back in the lab, we collated all the feedback and, based on a range of criteria, gave each product an overall score out of 100.
Why trust the Good Housekeeping Institute?
Our sleep and wellness editor, Priyankaa Joshi, and our senior sleep and wellness tester, Kim Hawley, have both been working at the Good Housekeeping Institute for a number of years, testing and reviewing health and sports nutrition supplements including the best greens powders, the best menopause supplements, the best mushroom coffees and more.
For this test, we also enlisted the help of two nutritionists to analyse the products and their ingredients against their claims.
We've been testing products for over 100 years at the Good Housekeeping Institute and even have an in-house gym, so we know what separates a great buy from a disappointing one. Whether it’s throwing suitcases down the stairs, wearing waterproof jackets in the shower or bouncing on mattresses, our dedicated teams rigorously review products exactly as you use them at home. They design strict testing protocols to measure each one against, so we can bring you fair and unbiased results.
What to look for in a sleep supplement
With so many brands and products to sift through, how do you know which sleep supplement to go for? According to Patel, you should prioritise evidence-based ingredients that are known to aid relaxation. Here are some to look out for.
Valerian root: This is a herbal remedy that comes from the valerian plant. There’s some research to suggest it can aid sleep, especially if you have occasional insomnia, are experiencing a temporary disruption to your sleep routine or you’re post-menopausal.
Passionflower: Another traditional herbal supplement, passionflower is thought to promote relaxation, ease anxiety and encourage sleep. It’s often used in combination with other sleep-inducing herbs like valerian, lemon balm and hops.
Note, passionflower should be avoided if you’re taking medications like benzodiazepines or barbiturates, as it can increase the effects of sedatives.
Magnesium: Magnesium is all the rage right now, and there's plenty of evidence to suggest the mineral can improve sleep duration and quality. It works by activating the parasympathetic nervous system, helping you feel calm and relaxed. It also plays a role in nerve function and muscle relaxation.
5-HTP: Another popular ingredient, 5-HTP is a compound that raises the level of serotonin (the feel-good hormone) in the brain. This excess serotonin is converted into melatonin, the hormone that regulates our sleep. 5-HTP is thought to help ease anxiety and support slumber.
L-theanine: An amino acid found in tea, there is some research to suggest L-theanine encourages relaxation, reduces stress and aids sleep. It’s often used in combination with magnesium.
