We’ve reviewed the best sleep supplements in the UK for you - after testing some of the most popular!

by Hanitra Rama

Sleep is the most important thing when it comes to helping the body recover, refreshing the brain and elevating your general wellbeing.
However, many of us are not getting enough sleep. In fact, the average Brit sleeps between 5.78-6.83 hours a night. This means that they are missing out on an average of 100 minutes of sleep per night.

With this in mind, it’s no surprise that so many people are interested in supplements to help them get a peaceful night’s rest.

What are sleep supplements?

Sleep supplements are often taken daily to help improve sleep duration and quality. They can come in a variety of forms, but they generally contain ingredients like melatonin, valerian root, lemon balm and 5-HTP. Sleep supplements are gathering huge momentum in the UK as more of us look to get help with our sleep. The tricky thing is, some are legal in the UK and some are not (like Melatonin!).

What are the different types of sleep supplements? 

Sleeping capsules

Sleeping capsules are one of the most popular forms of sleep supplements because they are easy to take and already have everything dosed for you. Sleeping capsules often contain a good balance of calming ingredients and will help you wake up feeling refreshed and not groggy in the morning. They’re easy to take, and easy to have as part of a night time ritual. 

Sleep tinctures

Sleep tinctures or sublingual sleep supplements are some of the easiest supplements to take. They usually come in a dropper, which makes it easy to dose. Tinctures are the best way to absorb the ingredients and thus work with your body the fastest. If you're looking for a fast-acting sleep supplement, tinctures would be the best way to go. 
Sleep tinctures can sometimes be confused with CBD oil products. While there area lot of CBD oils that are formulated for sleep, they often have other ingredients like Valerian Root or Chamomile to support the effects of CBD. But not all sleep tinctures contain CBD, some are made with only herbal and calming ingredients.

Sleeping pills

While there are some sleeping pills that are available over-the-counter, sleeping pills are often prescribed by a doctor and need to be taken at a certain time to work. They usually contain more powerful ingredients to put you to sleep, compared to supplements, which are often made with more natural ingredients that promote sleep. 

Over-the-counter sleeping pills are usually made with active ingredients like antihistamines, which are categorised as sedatives. These ingredients will put you to sleep, they are approved and licensed to be sold over-the-counter but you can expect some mild side effects after taking them such as drowsiness and at times a slight dizzy feeling. 

What vitamins and minerals are often found in sleep supplements?

Many sleep supplements use ingredients inspired by ancient and traditional medicine. The soothing effects of these vitamins and minerals have been accentuated with new ingredients, and repurposed into supplements that a person can easily take as part of a daily routine:

  • Ashwagandha is an ancient medicinal herb that’s been used for centuries to naturally help relieve stress and anxiety. Both the root and the leaves can be used in supplements and recipes.

  • Reishi is an adaptogenic mushroom that can help support sleep quality. Reishi helps reduce stress levels and make you feel calmer. Taking a reishi supplement before bed will make you feel more relaxed and prepare your body and mind for a better night’s sleep.

  • Valerian Root is one of the most used ingredients in supplements that promote better sleep and reduce anxiety. This herb has been used in Traditional Medicine for centuries and is one of best natural remedies for stress and sleep

  • Magnesium is one of the most versatile ingredients - it can help with muscle relaxation, digestion and even sleep. Magnesium helps relax your body to help you feel fully relaxed and sleep a lot better.

  • 5-HTP is used by the body to produce serotonin, our happy hormone. Low serotonin levels are often linked to sleep disorders, which is why 5-HTP is often used in sleep supplements.

What are the common ingredients in herbal sleep supplements?

Natural alternatives are an incredibly popular solution for people looking to get a good night’s rest. Many of the products included in this review are inspired by natural remedies, and several of them offer additional benefits. Here is just a little context that could help you find your ideal sleep supplement:

  • Lemon Balm is an herb traditionally used to boost cognitive function but we now often see it as an ingredient in sleep supplements. This relaxing herb can help reduce stress and anxiety, which can have a significant impact on your sleep cycle. It’s a great ingredient to have in the evening but also in calming teas during the day. 

  • Chamomile is calming for the mind and body and is often added in herbal night time teas. Apart from being a sleep aid, it can also calm mild inflammation like the early symptoms of a sore throat. It pairs perfectly with other calming ingredients like lemon balm or passionflower. 

  • Hops are traditionally an herbal medicine often used to help treat insomnia, especially when it is related to stress and anxiety. While hops is usually known for its pleasant bittersweet and floral taste, it is often added to sleep tinctures to help ease your mind and help you nod off faster. 

  • Passionflower can improve sleep quality and duration by stopping you from waking up at night. Those of you who may be troubled by racing thoughts and nighttime worries will find themselves calm and ready to drift off to sleep.

  • Skullcap is a nootropic that boosts your mood, thus reducing symptoms of stress and anxiety. It is often found in teas but is also available as a supplement in powder or capsule form.

Can sleep supplements help with stress/anxiety?

One of the main causes of bad sleep is the stress we inflict on our bodies and minds during the day. This usually leads to racing thoughts at night and tends to keep us from being able to fall asleep. If this is your case, we highly recommend taking sleep supplements with ingredients like lemon balm or passionflower. Sleep is the time where our bodies and minds get to reset, getting better quality and deeper sleep will help reduce daily stress and anxiety. We would also recommend trying to take supplements for anxiety during the day.

Will I wake up feeling drowsy after using sleep supplements?

The sleep supplements we recommend are all made with natural ingredients that work well with the body and will not make you feel drowsy in the morning. This depends on people, as some have more difficulties waking up in the morning than others.

How often should I take sleep supplements?

In order to be as efficient as possible, it’s recommended to take sleep supplements every evening. Just like any other supplement, consistency is key. The more you will take a supplement, the more your body will get used to it and interact with it. 

Should I be taking sleep supplements on a long-term basis?

Sleep supplements are recommended to take as a last resort if you can’t find another more natural solution to fall asleep. We have chosen these sleep supplements as the best solutions because of their natural formulas, which means that your body will not become dependent on any of the ingredients.

You can take sleep supplements on a long-term basis, especially if you feel like they are really helping your sleep quality. We would however recommend trying to take nights off from taking sleep supplements to see if your body has gotten used to this new circadian rhythm. 

Should I speak to my doctor about sleep supplements?

While the products we recommend are made with natural ingredients, it’s always recommended to speak to a doctor before taking them, especially if you’re on medication or follow a treatment. This recommendation is valid for any type of supplement. 

In a nutshell, if you’re having trouble falling asleep, are waking up during the night or don’t feel rested in the morning, sleep supplements might be the solution for you. With calming and relaxing ingredients, your body and mind will find the calm they need to help you drift off easily.
