Struggling to fall asleep and considering a trendy supplement to help you drift off naturally? Lemme Sleep Gummies—founded by Kourtney Kardashian—have exploded in popularity thanks to celebrity backing, clean branding, and a promise of better sleep without the grogginess. But do they actually work?
And more importantly for UK buyers: are Lemme Sleep Gummies available in the UK?
In this in-depth review, we’ll break down the ingredients, benefits, side effects, and UK availability of Lemme Sleep Gummies so you can decide whether they’re worth adding to your bedtime routine.

What Are Lemme Sleep Gummies?
Lemme Sleep is a vegan, non-GMO sleep supplement in gummy form, designed to help support relaxation and sleep quality. Each gummy is purple, berry-flavoured, and looks like something you might find in a wellness gift box—but it’s marketed as more than just pretty packaging.
Key Claims:
Help you fall asleep faster
Support sleep quality and duration
Wake feeling refreshed, not groggy
Lemme Sleep Ingredients Breakdown
Each serving (2 gummies) contains:
1. Melatonin – 5mg
A popular sleep aid that helps regulate your circadian rhythm. Studies show melatonin may reduce sleep latency (time to fall asleep), especially for people with jet lag or sleep cycle disruption.
2. Magnesium – 50mg
Supports muscle relaxation and nervous system function. Low magnesium levels are linked to poor sleep quality.
3. L-Theanine – 25mg
An amino acid found in green tea, known for its calming effects without sedation. Can promote alpha brain waves and improve sleep onset.
4. Chamomile, Lavender, Lemon Balm Extracts
These calming herbs are frequently used in teas and traditional sleep remedies. While research is limited, they may promote relaxation and anxiety reduction.
5. Other Ingredients:
Includes tapioca syrup, cane sugar, natural flavours, and colours from fruit/vegetable juice.
Do Lemme Sleep Gummies Actually Work?
Pros:
Solid ingredient profile – Combines melatonin, magnesium, and calming botanicals
Vegan-friendly and gluten-free
Tastes pleasant, easy to take
Minimal risk of grogginess compared to other sleep aids
Cons:
Melatonin dose may be too high for some – UK guidelines recommend starting at 1mg or lower
Not suitable for daily long-term use without medical advice
Effectiveness may vary – Particularly if your sleep issues are stress-related or hormonal
Most users report falling asleep faster and feeling relaxed before bed, though it may not dramatically increase total sleep time or depth of sleep for everyone.
Lemme Sleep Gummies: UK Availability
As of now, Lemme Sleep Gummies are not officially stocked by UK retailers, including Boots, Holland & Barrett, or Amazon UK.
However, UK customers can:
Order directly from the Lemme website (international shipping available)
Import via US-based Amazon or third-party health sites
Important Note: Products containing melatonin are classified as medicines in the UK and are not permitted for over-the-counter sale. Melatonin supplements can only be prescribed by a healthcare provider.
This means that even though you can import Lemme Sleep Gummies, they are not MHRA-approved for general sale in the UK.
Are There UK-Approved Alternatives?
If you're looking for a UK-legal alternative to Lemme Sleep, try:
Vitabiotics Sleepnite – Herbal blend with valerian, hops, chamomile
Veranite - A powerful all-natural sleep aid made in the UK
Pukka Night Time Capsules – Valerian root and ashwagandha
Magnesium glycinate – Available from brands like BetterYou and Solgar
Final Verdict: Should You Try Lemme Sleep Gummies?
If you're based in the US or don’t mind importing, Lemme Sleep Gummies offer a stylish, decent-quality blend of popular sleep ingredients. For short-term use or travel-related sleep disruption, they’re a convenient choice with a good safety profile for most adults.
However, if you’re in the UK, it’s worth remembering that melatonin is regulated and not available OTC. There are other effective, herbal-based options that won’t run afoul of import rules.
Bottom Line:
Lemme Sleep Gummies are well-formulated and appealing—but in the UK, legal limitations on melatonin mean they're not a straightforward purchase. Consider UK-approved sleep supplements unless advised otherwise by a healthcare professional.
