The Science of Deep Sleep

Advanced night-time blend for restful sleep.

Deepest Sleep is a specialist natural sleep aid supplement designed to help you unwind, relax, and wake up feeling refreshed. It combines natural botanical ingredients with amino acids and essential minerals to support the nervous system.

Many herbal sleeping tablets leave you feeling groggy the next morning. We have created a formula that works with your body's natural rhythms, not against them. This synergistic formula pairs Montmorency Tart Cherry with adaptogens like Ashwagandha and calming herbs like Lavender and Passion Flower to help settle a busy mind before bed.

• Wake Up Refreshed: Designed to help you drift off naturally so you wake up feeling energised, without the "hangover" effect of strong sedatives.
• Nervous System Reset: Contains Magnesium and Vitamin B6 to support the nervous system and reduce tiredness and fatigue.
• Non-Habit Forming: 100% vegan formula designed to support your natural routine without creating dependency.

Active Ingredients Matrix

We have grouped our active ingredients by their biological targets to provide comprehensive, multi-phase sleep support:

• Circadian Rhythm: Montmorency Tart Cherry provides specific antioxidants and phytochemicals (whole food support) that support the body's natural night-time cycles.
• Mental Calm: L-Theanine (an amino acid found in tea) and Lemon Balm help promote a state of relaxation, quieting the "internal chatter" that keeps us awake.
• Stress Modulation: Ashwagandha Root is a renowned adaptogen that helps the body manage its response to stress, preventing cortisol spikes in the evening.
• Physical Relaxation: Magnesium, Passion Flower, and Lavender work synergistically to help relax muscles and soothe tension in the body.

*Please see the product images for the full nutritional label and complete ingredient list.

How to Use

Take 1 to 2 capsules with water, approximately 30 minutes before bed.

Active Tip: Consistency is key. Try to take these natural sleeping pills at the same time each evening to help signal to your body that it is time to wind down.

Backed by Science & Quality

This formula utilises ingredients backed by clinical research into sleep and relaxation. Explore the clinical data:
