If you’ve been scrolling TikTok or Instagram lately, you’ve probably seen Lemme Sleep gummies popping up in wellness routines. Created by Kourtney Kardashian’s brand, these gummies promise better rest with a blend of melatonin and botanicals and they’ve attracted a huge fanbase in the US.

But if you live in the UK, you’ll quickly notice they’re nowhere to be found online. That’s because melatonin, the main active ingredient in Lemme Sleep isn’t approved for over-the-counter sale here.

Let’s break down why, and what you can use instead if you want to improve your sleep naturally.

Why Lemme Sleep isn’t available in the UK

The difference comes down to UK supplement regulations. In the US, melatonin is sold as a dietary supplement. In the UK (and most of Europe), melatonin is classed as a prescription-only medicine. It’s available from a doctor in certain situations, for example, to treat short-term insomnia in people over 55, but it’s not approved for general use as a supplement.

There are two main reasons for this stricter regulation:

• Potential side effects: Melatonin can cause next-day grogginess, dizziness, headaches, and in some cases, affect mood or hormonal balance.
  
• Concerns over dependency: Using melatonin regularly can interfere with your body’s own production, making it harder to fall asleep without it.
  

For these reasons, you won’t find Lemme Sleep gummies in UK shops and importing them for personal use could mean they get stopped at customs.

Why Habitual took a different approach

At Habitual, we know good sleep is the foundation for everything. Your energy, your mood, your focus, and even your weight loss journey. But we also know that knocking yourself out with sedatives or high-dose melatonin isn’t the answer for most people.

That’s why we created Habitual Deep Sleep: a vegan, gluten-free, melatonin-free formula that works with your body’s natural sleep cycles rather than overriding them.

Our goal? Help you fall asleep faster, stay asleep for longer, and wake up refreshed, without brain fog, dependency, or the “sleep hangover” that can come from stronger sleep aids.

How Habitual Deep Sleep works

Instead of relying on a single sedative, we’ve built a science-led blend of botanicals, minerals, and amino acids — each one chosen for a specific role in your sleep cycle:

• L-Theanine (200mg) — An amino acid from green tea that helps calm the mind, reduce racing thoughts, and prepare your body for rest.
  
• Montmorency cherry (100mg) — Naturally rich in melatonin and tryptophan, supporting your body’s own sleep–wake rhythm.
  
• Vitamin B6 (1mg) — Key for producing serotonin and melatonin, the brain chemicals that regulate sleep.
  
• Magnesium (100mg) — Supports GABA activity, calming nerve activity so your body can relax.
  
• Chamomile (100mg) — Traditionally used to reduce anxiety and aid relaxation before bed.
  
• Lemon balm (60mg) — Helps ease restlessness and promote a calm mood.
  
• Saffron (30mg) — Linked to better sleep quality by acting on serotonin and GABA.
  
• Zinc (5mg) — Supports cell repair and healthy immune function, with some evidence for improving sleep quality.
  
• Black pepper extract (16mg) — Enhances absorption of other nutrients in the formula.
  

Why it’s different from other sleep aids

• Melatonin-free — No risk of dependency or “switching off” your natural sleep signals
  
• Non-sedating — Supports natural sleep cycles instead of forcing sleep.
  
• No grogginess — Designed so you wake up clear-headed.
  
• Safe for long-term use — Gentle on the system and can be taken nightly.
  
• More than magnesium — While some supplements rely on a single mineral, Habitual Deep Sleep combines multiple clinically supported ingredients for a holistic effect.
  

The benefits you can expect

• Fall asleep faster and stay asleep longer
  
• Wake up feeling refreshed, not groggy
  
• Reduce mental tension before bed
  
• Support serotonin and melatonin production naturally
  
• Improve overall sleep quality over time
  

And because better sleep supports hormone regulation, reduces cortisol, and boosts metabolism, it can also help you get more from your weight loss journey, especially if you’re using GLP-1 medication like Mounjaro or Wegovy.

The bottom line

While Lemme Sleep might look appealing, UK rules mean melatonin-based supplements aren’t available without a prescription and for good reason. For many people, a gentler, non-sedating approach is safer, more sustainable, and just as effective in the long run.

Habitual Deep Sleep offers that approach with a carefully balanced blend of botanicals and nutrients to help you drift off naturally, stay asleep, and wake up ready to take on your day.

Your best sleep doesn’t need to come from a banned gummy. It can come from supporting your body’s own rhythms, night after night.
