Sleep Better, Wake Recharged – Natural Support for Deep Rest

Struggling with restless nights, tossing and turning, or waking up feeling unrefreshed? Quality sleep is one of the most powerful and underrated pillars of long-term health and vitality. But in today’s fast-paced world, it’s increasingly common to experience poor sleep due to stress, inflammation, or an imbalanced nervous system.

That’s why our Sleep collection is designed to support your body’s natural rhythm — helping you fall asleep faster, stay asleep longer, and wake up restored.

Why Sleep Quality Matters

During sleep, your body doesn’t shut down — it repairs, regenerates, and resets. Deep sleep is when:

  • Cells detoxify and regenerate
  • Hormones like melatonin and growth hormone are released
  • Immune function and memory are strengthened
  • Mood-regulating neurotransmitters are balanced

When sleep is shallow or disrupted, it affects not just energy, but mood, immunity, metabolism, and cognitive clarity.

Instead of relying on harsh sleep medications or melatonin overload, our supplements offer gentle, natural support to promote calm, reduce internal stress, and encourage restful sleep.

Supplements Supporting Sleep Quality

NAC (N-Acetyl Cysteine)

NAC is an antioxidant powerhouse that indirectly promotes sleep by supporting glutathione production — the body’s master detoxifier. But NAC also plays a critical role in balancing neurotransmitters like glutamate and dopamine, which are key to reducing mental hyperactivity and emotional overwhelm before bed.

Benefits of NAC for sleep:

  • Regulates stress-induced brain activity
  • May help with racing thoughts or sleep-related anxiety
  • Enhances overnight recovery by reducing oxidative load

NAC is ideal for those whose sleep is disrupted by stress, inflammation, or difficulty switching off at night.

 

Longevity Greens

This daily greens blend supports gut health, immune balance, and nervous system calm — all vital for sound sleep. Ingredients like barley grass, spirulina, and digestive enzymes help the body wind down by nourishing the gut-brain axis. A healthy gut produces the majority of serotonin, which is a precursor to melatonin — your body’s natural sleep hormone.

Benefits of Longevity Greens for sleep:

  • Balances the microbiome for melatonin production
  • May reduce nighttime bloating or discomfort
  • Supports adrenal recovery and circadian rhythm balance

If your sleep is affected by digestive issues, stress, or poor nighttime recovery, this formula offers holistic support.

Who This Sleep Range Is For

  • Anyone with difficulty falling or staying asleep
  • Those with high stress, mental overstimulation, or anxious thoughts
  • Biohackers and wellness seekers looking for non-habit forming solutions
  • People who wake up tired despite a full night in bed
  • Anyone looking to improve brain detox, mood, and immune function overnight

Sleep Support That Works with Your Body — Not Against It

We don’t believe in quick-fix sleep aids that knock you out or leave you groggy. Our approach is different. We offer science-backed, adaptogenic, and antioxidant-rich supplements that help your body restore balance naturally — so you can sleep deeply and wake up energised.

 

NAC and Longevity Greens work synergistically to reduce inflammation, nourish the gut-brain axis, and support calm, resilient sleep cycles. Whether you're struggling with chronic fatigue, post-pandemic burnout, or just need a healthier night-time routine, this duo is designed to help you reclaim your rest.

Try Our Sleep Stack

Many users report the best results by using NAC during the day (for antioxidant and mood regulation) and Longevity Greens in the afternoon or early evening to gently prepare the body for rest. Over time, these work with your body’s natural rhythms to improve both the quality and depth of your sleep.
