Sleep Supplements: Supporting Better Rest Naturally

Quality sleep is one of the building blocks of good health. It allows the body to rest, recover and prepare for the next day. However, statistics show that many people struggle to get enough quality sleep.

35% of adults in the US [1] and 71% of adults in the UK [2] report they sleep less than seven hours per night.

A growing number of people are exploring natural sleep supplements and sleep vitamins to support their routine - with ingredients like Magnesium, Glycine, Ashwagandha, Apigenin and CBD.

These supplements for sleep are available in a range of formats including capsules, powder and sleep gummies, making it easy to build a routine that fits your lifestyle.

Sleep Bundle

£77.99
View Details

Discover our Sleep Bundle - a science-backed trio of sleep supplements crafted to support your evening wind-down. Includes 10% CBD Oil, Triple Magnesium Powder, and Glycine. Complete your natural sleep supplement stack with our Apigenin (now available in the sleep collection) and KSM-66 Ashwagandha.

Looking to build a full evening routine? These four ingredients form a research-informed stack for natural sleep support.

Natural Sleep Supplements: What Each Ingredient Does

Not all sleep supplements work the same way. The ingredients in our collection have each been studied for their potential to support sleep quality through different mechanisms. Here is what the research says about each ingredient.

Triple_Mag_Caps_HR.webp__PID:58892a36-3bf7-4971-99f6-513f61cee0b0

Magnesium

One of the most widely studied sleep vitamins and minerals, magnesium contributes to the reduction of tiredness and fatigue and to normal psychological function (EFSA-authorised claim). Our Triple Magnesium Bisglycinate 3:1 provides three complementary forms for optimal absorption. Research in a clinical population found a potential relationship between magnesium and the time it takes to fall asleep. [3]

Glycine from Naturecan

Glycine

Glycine is a naturally occurring amino acid and one of the simplest in structure. It is found in protein-rich foods including meat, fish, dairy, and particularly collagen. It has been studied in the context of sleep and cognitive recovery, with a number of clinical trials examining its effects. Research is ongoing and results are preliminary. [4]

KSM-66® Ashwagandha

KSM-66 is a standardised, root-only extract of Withania somnifera (ashwagandha) and has been used for thousands of years in Ayurvedic tradition. Many people choose to take it as part of their wind-down routine before bed. A 2019 double-blind, randomised, placebo-controlled trial (Langade et al.) examined KSM-66 root extract in the context of everyday stress management and a range of wellbeing outcomes [5]. Results may vary; allow 4-8 weeks for assessment.

Apigenin Product Imagery.webp__PID:8714a84c-f444-4a3b-a7d5-1f6d801c3647

Apigenin

Apigenin is a natural flavonoid found in chamomile and parsley. Chamomile has been used in herbal tradition across Europe and beyond for centuries. Popularised as part of an evening supplement routine alongside Magnesium, it is included in Naturecan's sleep collection. Each serving provides 100 mg from high-quality parsley extract.

When to Take Sleep Supplements

Taking sleep supplements at the right time makes a meaningful difference to their effectiveness. Most natural sleep supplements work best when taken 30 to 60 minutes before bed, giving the body time to absorb the ingredients as part of your evening wind-down. Here is a breakdown by ingredient:

Magnesium

The best time to take magnesium for sleep is 30 to 60 minutes before bed. It can be taken with or without food and is available as magnesium sleep tablets (capsules) or powder.

Magnesium for sleep UK users: if you are new to magnesium supplementation, begin with the 90-capsule (30-day) pack to assess tolerance before scaling to a larger supply. Magnesium supplementation studies have typically used trial periods of 6–8 weeks to assess outcomes [3]. For best results, take magnesium consistently as part of a daily evening routine rather than occasionally, and allow sufficient time before evaluating your response.

Glycine

Take 3-5g of Glycine 30 to 60 minutes before sleep, dissolved in water or a warm drink. Glycine has a mildly sweet taste and is well-tolerated. For best results, glycine is most commonly taken as a daily supplement rather than occasionally.

KSM-66® Ashwagandha

Ashwagandha can be taken morning or evening. For sleep support, taking it in the evening, with dinner or 30 minutes before bed, may help support the body's adaptation to everyday stress. Results may vary; allow 4–8 weeks for assessment.

Apigenin

Take one Apigenin capsule (100mg) 30 to 60 minutes before bed, ideally alongside your Magnesium supplement. Apigenin is best absorbed with a small amount of food or water.

CBD

CBD oil taken sublingually (under the tongue) begins to take effect within 15 to 30 minutes. CBD capsules pass through the digestive system, taking longer to work (typically 1 to 2 hours).

Who Are Sleep Supplements For?

Natural sleep supplements suit a range of lifestyles and sleep concerns:

Athletes and those
training in the evening

Magnesium for sleep and recovery. The magnesium-sleep connection is well-documented: magnesium contributes to the reduction of tiredness and fatigue and supports normal muscle function. Glycine can be taken as part of the same evening routine.

Shift workers and
those with irregular hours

The sleep supplement stack (Magnesium + Glycine + Apigenin) can be incorporated into an evening routine regardless of when you sleep, making it a practical option for non-standard schedules.

Women during perimenopause
and menopause

Sleep disruption is commonly reported during the menopausal transition. Magnesium contributes to the reduction of tiredness and fatigue and to normal psychological function (EFSA-authorised claim). KSM-66 Ashwagandha has been the subject of published research into everyday stress management, which is a common concern during this life stage [5]. Results may vary.

woman lay awake.jpg__PID:41ffe061-b54c-49e6-bc9e-ac4f32e0a6a54

Those affected by stress-related sleep disruption

KSM-66 Ashwagandha and Magnesium are often used together as part of an evening routine focused on managing everyday stress. Magnesium contributes to the reduction of tiredness and fatigue and to normal psychological function. If stress is your primary sleep concern, start with the Ashwagandha and build the full stack from there.

General wellness

The Sleep Bundle (10% CBD Oil + Triple Magnesium Powder + Glycine) is the most accessible starting point, combining three complementary natural sleep supplements in one package.

What Can Disrupt Sleep?

Sleeping problems can be caused by a range of physical, mental and environmental factors, including:

  • Pain or discomfort
  • Stress, anxiety or depression
  • Respiratory difficulties or allergies
  • Alcohol or caffeine
  • Medication
  • Excessive screen use
  • Shift work
  • Excessive noise or light

Some people exploring natural sleep supplements do so as part of managing everyday stress and fatigue.

Ashwagandha has been studied for its potential role in supporting the body's response to everyday stress, while Magnesium contributes to the reduction of tiredness and fatigue and to normal psychological function. Glycine is included as part of this evening routine.

To explore the research in more depth, read our article on ‘Why Can't I Sleep?’ or discover how individual sleep supplements may support your evening routine.

How much sleep do we need?

How much sleep do we need?

The amount of sleep we need decreases as we age. On average, healthy adults aged 18 and over need 7-9 hours sleep per night, while teenagers need 8-10 hours, children 9-14 hours and infants 12-15 hours. [7]

Different phases of sleep

There are four stages of sleep. Stages 1 to 3 are known as non-rapid eye movement (non-REM) sleep, and stage 4 is the rapid eye movement (REM) phase. Each night, our brains go through these four stages several times. Each stage gets longer and the sleep gets deeper with every cycle. [6]

FAQs

Where to buy CBD oil online?

You can buy CBD oil online from trusted sellers like Naturecan. We offer a range of CBD products, all THC-free (<0.01%) and third-party tested to guarantee quality.  

Can I take CBD drops before sleep?

Yes, you can take CBD drops before going to sleep, or at any time of day that suits you best.

Difference between CBD oil and CBD capsules

CBD oil and CBD capsules both deliver CBD in oral form, but they differ in terms of their administration method, speed of effect and bioavailability. CBD oil drops are placed under the tongue using a dropper and left there for about a minute before swallowing. This sublingual administration is thought to allow the CBD to be absorbed directly into the bloodstream via the blood vessels under the tongue. As a result, sublingual application may allow faster absorption than other oral forms such as capsules. On the other hand, as CBD capsules must pass through the digestive system before entering the bloodstream, they take much longer to have an effect (1-2 hours). However, the effects can last for up to 6-8 hours, which makes CBD capsules a good option for people looking for a longer effect.

What is the best natural sleep supplement in the UK?

The most suitable best sleep supplements UK choice depends on your needs. Magnesium is one of the most widely researched options. If stress is a primary factor, KSM-66 Ashwagandha may offer additional support. Glycine and Apigenin are also well-suited to an evening wind-down routine. Our Sleep Bundle combines Magnesium, Glycine and 10% CBD Oil for a ready-made starting package.

Can magnesium help with sleep?

Magnesium contributes to the reduction of tiredness and fatigue and to normal psychological function - a permitted UK food law health claim. Our Magnesium Bisglycinate 3:1 provides three complementary forms for optimal absorption and can be taken as part of an evening routine. It is one of the most commonly recommended sleep vitamins among nutritional practitioners in the UK.

Is ashwagandha good for sleep?

KSM-66® is a standardised, root-only extract of Withania somnifera (ashwagandha) that has been the subject of published research into everyday stress management. It is most commonly used as part of a broader evening routine.

What is apigenin and how does it support sleep?

Apigenin is a natural flavonoid found in chamomile and parsley. It is included in Naturecan's sleep collection as part of an evening wind-down routine. Each serving provides 100mg Apigenin from high-quality parsley extract.

What is a sleep supplement stack?

A sleep supplement stack is a combination of natural supplements taken together to support better sleep from multiple angles. Magnesium (contributing to the reduction of tiredness and fatigue and to normal psychological function), Glycine, and Apigenin as part of an evening routine. Naturecan's Sleep Bundle provides a ready-made starting point, and individual supplements, including KSM-66 Ashwagandha and Apigenin, can be added to build a personalised routine.

How long does magnesium take to work for sleep?

The time varies between individuals and depends on existing magnesium levels and how consistently supplementation is maintained. Magnesium builds gradually with daily use. Research examining magnesium supplementation in a clinical population used an 8-week trial period to assess outcomes [3]. For best results, take magnesium consistently as part of a daily routine rather than occasionally, and allow at least 4–8 weeks before evaluating your response.

Which magnesium is best for sleep?

Magnesium bisglycinate is widely considered the “best magnesium for sleep” due to its high bioavailability and gentle effect on the stomach. Unlike magnesium oxide or magnesium citrate, bisglycinate is bound to the amino acid glycine, which supports absorption and reduces the digestive discomfort some people experience with other forms. Naturecan's Magnesium Bisglycinate 3:1 combines bisglycinate with two additional forms for a comprehensive approach - available as magnesium sleep tablets (capsules) or powder. Magnesium contributes to the reduction of tiredness and fatigue, making it one of the most evidence-backed sleep vitamins available in the UK.
