A hormone-free, science-backed approach to deeper, more restorative sleep.

Unlike most sleep supplements that rely on melatonin or sedatives to force sleep, we intentionally designed Sereniser to support your body’s natural sleep-wake cycle – without disrupting your hormones, creating dependency, or leaving you drowsy the next day.

Formulated with leading longevity researchers in Switzerland, it takes a multi-pathway approach grounded in neuroscience, adaptogens, and chronobiology. Each ingredient was selected for its ability to target key systems involved in high-quality sleep – mood regulation, cortisol balance, circadian rhythm, and sleep architecture – without interfering with your body's natural rhythms.

What makes the Sereniser different:

1. Calms the body and mind 

The Sereniser helps ease the physiological and mental tension that can keep you alert, even when you feel tired.

• L-Theanine – Promotes calming alpha brain waves to create a relaxed, pre-sleep mental state.
• Holixer® (Holy Basil) – A clinically studied adaptogen shown to reduce cortisol levels and improve resilience to nighttime stress.
• Safr’Inside™ (Saffron extract) – Enhances serotonin activity to improve pre-sleep mood, reduce anxiety, and promote natural relaxation.
  

2. Supports deep, uninterrupted sleep
Rather than simply sedating the brain, Sereniser helps the body reach and maintain deep, restorative sleep stages.

• Serezin™ (Ginger + Frankincense) – A patented plant-based complex that reduces inflammation-related discomfort and nighttime awakenings.
• Magnesium Bisglycinate – A gentle, more bioavailable form of magnesium that relaxes muscles and the nervous system to reduce tossing and turning.
• Vitamin B6 + Safr’Inside™ – Together support the natural production of melatonin and GABA, promoting continuous, undisturbed sleep.
  

3. Balances your internal rhythm

Rather than flooding the system with synthetic melatonin, Sereniser helps regulate your body's own circadian rhythm to promote consistency and better mornings.

• Holixer® – supports healthy cortisol patterns, helping the body wind down more easily in the evening.
• Safr’Inside™ – enhances serotonin-to-melatonin conversion for smoother transitions into sleep.
• Vitamin B6 & Magnesium – help reinforce steady sleep patterns by supporting GABA and neurotransmitter balance.
  
  

4. Non-habit forming & melatonin-free

Many sleep supplements rely on synthetic melatonin, which can disrupt your natural rhythm and lead to dependency over time. Sereniser takes a more natural, longer-term approach:

• No hormonal interference
• No tolerance build-up over time
• No residual drowsiness or sedation the next day

Just deep, consistent rest - the way your body was designed to experience it.

Women experience sleep differently – and this becomes especially noticeable during perimenopause and menopause. Despite maintaining consistent routines, many begin to experience new or worsening sleep disruptions: difficulty staying asleep, early morning awakenings, or waking feeling less restored than before.

These changes are not imagined – they’re physiological.

As estrogen and progesterone begin to decline, they also influence the release and amount of other hormones and neurotransmitters that regulate sleep:

• Melatonin, which governs circadian rhythm
• Cortisol, which impacts stress and sleep fragmentation
• Serotonin, which helps calm the nervous system and initiate deep rest
  

When these hormones and neurotransmitters are thrown out of balance, sleep becomes lighter, more fragmented, and more easily disrupted. Hot flashes, increased nighttime cortisol, and changes in thermoregulation all add to the challenge – even for women who’ve never struggled with sleep before.

Sleep during menopause is also more sensitive to stress, screen exposure, diet, and even small environmental changes. The nervous system becomes more reactive, and the body may cycle in and out of sleep stages more frequently.

But these shifts go beyond night-time rest.

Because deep sleep plays a key role in hormone regulation, immune resilience, and cognitive repair, a decline in sleep quality during menopause can also impact long-term energy, clarity, and healthy ageing.

And yet, most sleep solutions aren’t designed with women in mind — let alone with the complexity of hormonal transitions.

Understanding the root causes of disrupted sleep in midlife is essential to supporting better rest – and better health – for decades to come.
