What makes your sleep supplements different from melatonin or sleeping pills?

Our sleep supplements work with your body’s natural rhythms. They don’t sedate or override sleep cycles. Instead, they reduce internal stress, balance neurotransmitters, and support deep, natural rest — without grogginess or dependency.

How does NAC help with sleep?

NAC supports glutathione production and regulates brain activity by modulating neurotransmitters like glutamate and dopamine. This can ease anxious thoughts and promote a calmer mind at night.

Can I take Longevity Greens at night?

Yes, many people take Longevity Greens in the afternoon or early evening. It supports gut-brain balance and helps your body prepare for rest naturally.

Are these sleep supplements safe for long-term use?

Absolutely. Our formulas are non-habit forming and free from synthetic sedatives. They’re designed for daily use to support sustainable, long-term sleep quality.

Who should use this sleep range?

Anyone struggling with falling asleep, waking often, or feeling tired despite a full night’s sleep. It’s also great for people with stress-related sleep issues or looking for holistic, natural support.

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
