The basics
What is Moongreens?
A night-recovery greens drink. Mix one scoop with water 30–120 minutes before bed to support deeper sleep, overnight recovery, gut health and next-day clarity. 20+ plant-based ingredients, no added melatonin, one scoop a night. Made in the USA.
Who is it for?
High-performing professionals, roughly 32–48, who fall asleep fine but wake unrecovered — the 3am wake-up, running on sleep debt by Thursday. People who've tried melatonin and watched it stop working. Not biohackers; just smart people who want one thing that works.
How is it different from other sleep supplements?
Three things set it apart. Clinically studied ingredients in bioavailable forms, not trace amounts for the label. It addresses the actual drivers of poor sleep in high performers — cortisol, sleep architecture, the gut-sleep axis — not just sleep onset. And it works without melatonin, so there's no tolerance, no receptor downregulation and no morning fog. More on the melatonin point here.
Is it a sleep aid or a greens powder?
Both, by design — and neither in the usual sense. It's a purpose-built night-recovery formula: sleep-specific actives plus a recovery layer of greens, vitamins and minerals. Not a daytime greens drink, not a sedative.
What does it taste like?
Natural Berry and Citrus — fresh and light, deliberately not the earthy, grassy taste typical of greens powders. Best cold.
How many servings in a bag?
30 servings — one scoop a night, so one bag is a month.
What is the serving size?
One scoop, about 8.5g. The bag is 255g (9oz) net weight, around 20 calories per serving.
The formula & ingredients
What's in it?
20+ plant-based actives built around ashwagandha (KSM-66®), magnesium bisglycinate, L-theanine, L-glycine and GABA, with a recovery layer of greens, tart cherry, a probiotic blend, and bioavailable vitamins and minerals. The complete Supplement Facts panel is on the product page.
What does KSM-66® ashwagandha do?
KSM-66® is the most clinically studied ashwagandha. It helps modulate the HPA axis — the system that governs cortisol — supporting the nervous-system wind-down and the wired-but-tired, 2–4am wake-up pattern. It builds over 6–8 weeks, which is why the protocol is 90 nights.
Why does the magnesium form matter?
Most cheap supplements use magnesium oxide — roughly 4% absorbed, with a laxative effect. Moongreens uses magnesium bisglycinate chelate: highly absorbable and gentle on the gut. The number on the label is meaningless if your body can't absorb it. More here.
What does L-theanine do?
It promotes alpha brainwave activity — the calm of meditation — without sedation, quieting the mental noise that keeps high performers awake at the start of the night.
What does glycine do?
L-glycine helps lower core body temperature, the main physiological trigger for slow-wave (deep) sleep onset.
Why is there a probiotic in a sleep supplement?
Because about 90% of serotonin — the precursor to melatonin — is made in the gut. The probiotic blend and prebiotic fiber support the gut-sleep axis alongside the sleep-specific actives. More on that link here.
Why are there greens in it?
Spirulina, spinach, wheatgrass and broccoli add micronutrient density that supports overnight cellular repair — which is what makes Moongreens a recovery formula, not just a sleep aid.
Are the ingredients clinically studied?
The formula uses clinically studied ingredients in bioavailable forms rather than trace amounts for label optics. Exact amounts per serving are on the Supplement Facts panel on the product page.
Does it contain caffeine?
No. Zero caffeine — it's a night formula.
Is it vegan / plant-based?
Yes. Entirely plant-based; all ingredients are vegan.
Is it gluten-free, GMO-free, dairy-free?
Yes to all three, as stated on the packaging.
Does it contain allergens?
No. The label states: Allergens — None.
Is it sweetened? Any artificial sweeteners?
Lightly sweetened with steviol glycosides (a natural stevia-derived sweetener) — under 2g total sugars per serving, no sugar added and no artificial sweeteners.
Does it contain vitamins and minerals?
Yes — vitamin D3, vitamin C, B vitamins (B1, B3, B6, B12), zinc (as a bisglycinate chelate) and trace minerals, all relevant to overnight recovery. Amounts are on the panel.
The melatonin question
Why no added melatonin?
Because for most people melatonin is the wrong tool. Your body makes about 0.1–0.3mg at the onset of darkness; pharmacy tablets pack 5–10mg — dozens of times that. Flood the receptors nightly and they downregulate: you need more, then it stops working, and you wake groggy. Moongreens supports your own melatonin pathway instead. Full breakdown here.
Why did melatonin stop working for me?
Receptor downregulation. At supraphysiological doses your melatonin receptors lose sensitivity over time — the same dose does less, until it does nothing. Moongreens has no added melatonin and no tolerance mechanism: night 90 works like night 1.
Is melatonin bad for you long-term?
The core issue is dependency — supplying a hormone your body already makes, at doses far above what it expects, which downregulates your natural production. Whether that qualifies as harm is still researched, but tolerance, grogginess and reduced natural output are well documented. We go deeper here.
Why does melatonin cause morning grogginess?
It's the predictable result of taking a hormone at up to 100× the dose your body produces — your system is still clearing it come morning. Moongreens contains none, which is exactly why there's no hangover.
Can I take Moongreens if I currently take melatonin?
Yes, but stop the melatonin when you start rather than stacking both. Give your receptors 2–3 weeks to normalize and let the formula work as designed — supporting your own production rather than competing with an external dose.
How can it help me sleep without melatonin?
By supporting the mechanisms behind sleep rather than overriding them: ingredients that help modulate evening cortisol, quiet the nervous system, lower core body temperature for deep-sleep onset, and support your own serotonin-to-melatonin pathway.
How to take it
When should I take it?
30–120 minutes before bed — ideally 30–60 minutes before you start to unwind.
How do I mix it?
One scoop with 10–15 fl oz of water. Cold or room temperature brings the flavor through best. Stir or shake until dissolved.
Can I mix it with something other than water?
Yes — coconut water works well. Any liquid is fine. Just avoid anything caffeinated; it's a night formula.
Hot or cold?
Cold or room temperature is best for flavor. A warm mix is fine if you prefer a warm drink before bed.
Do I take it every night?
Yes — it's a nightly ritual, and the benefit is cumulative. Consistency over 90 nights is what matters.
What if I miss a night?
Just continue the next night. One missed night doesn't reset anything.
Can I take more than one scoop?
No — it's designed as a single-scoop serving. Don't exceed the recommended daily intake.
Can I take it with my other supplements?
Moongreens is built to replace a typical evening stack — magnesium, ashwagandha, greens, B vitamins, zinc — so you may be doubling up. If you're on medication or have a condition, check with your healthcare professional first.
Can I take it if I've had a drink?
On nights with a drink or two it still helps. It can't fully counteract heavier drinking — alcohol fragments sleep regardless. More here.
Can I take it if I drink coffee late?
Caffeine has a 5–7 hour half-life, so a 3pm coffee is still active at 10pm — cut caffeine by 2pm for best results. Moongreens helps but can't overcome active caffeine. More here.
Can I take it across time zones / for jet lag?
Yes. Take it 30–60 minutes before your intended sleep time in the new zone. Unlike melatonin it doesn't anchor to a fixed clock — it adapts to your schedule.
Can I take it on night shifts?
Yes. Take it 30–60 minutes before your intended sleep period, whatever the clock says.
Can I take it while fasting?
Yes — about 20 calories per serving, negligible for most fasting protocols. Check your protocol if you follow a strict zero-calorie fast.
What to expect
How long until I notice results?
L-theanine and glycine produce noticeable effects in the first week for most people — easier onset, less mental noise. The deeper KSM-66® effects (calmer cortisol response, fewer 3am wake-ups, real next-day energy) build over weeks 3–8. By night 90 most people have a new baseline.
What should I expect in the first week?
A calmer wind-down, easier sleep onset, possibly more vivid dreams as REM increases. Don't judge it in week one — you're in the early phase.
What about at 30, 60 and 90 days?
Around 30 days mornings start on the right side of baseline and the 3am wake-up eases. By 60 days the adaptogen stack is near full effect and HRV often trends up. By 90 days it's your new normal: consistent quality and genuine morning recovery.
I'm having vivid dreams — is that normal?
Common in the first 1–2 weeks, usually a sign of increased REM sleep, which is restorative. It typically settles by weeks 2–4. More on REM here.
I feel more tired since starting — why?
In the first week or two some people spend more time in deep sleep and feel that as heavier mornings while the body adjusts. It usually resolves within two weeks. If it persists, email support@moongreens.com (and check with your doctor if you're on medication).
I feel calm before bed but I'm not sleeping better yet.
That calm is the L-theanine and GABA working on wind-down — the first stage. The deeper quality gains, mainly from KSM-66®, build over 4–8 weeks. Stay consistent.
How do I know it's working?
Waking without needing to recover from sleep itself; the 2–4am wake-up easing; clearer mornings; not reaching for caffeine in the first hour. A wearable (Oura, Garmin, Whoop) can track deep sleep, HRV and sleep score over the 90 nights.
What if it's not working for me?
First check the timeline — under 6 weeks and the adaptogen stack hasn't reached effect — plus consistency and disruptors (alcohol, late caffeine, high stress). If you're consistent for 8+ weeks with no change, email support@moongreens.com and James reviews it personally. If you're a subscriber within 90 nights, you're covered for a full refund.
Safety & medical
Is Moongreens safe?
It's formulated with plant-based, clinically studied ingredients and manufactured in an FDA-registered, GMP-compliant facility. As with any supplement, if you're pregnant, breastfeeding, on medication or managing a condition, consult your healthcare professional first.
Is it for adults only?
Yes — not intended for under-18s. Keep out of reach of children.
Can I take it if I'm pregnant or breastfeeding?
Consult your healthcare professional before use. Standard precaution for any supplement, stated on the packaging.
Can I take it with prescription medication?
Consult your healthcare professional before use if you take prescription medication — standard guidance for any supplement.
Can I take it with SSRIs or antidepressants?
Moongreens contains Griffonia seed extract (a natural source of 5-HTP), which supports serotonin production. If you take SSRIs, SNRIs, MAOIs or other serotonin-affecting medication, speak to your doctor before use.
Can I take it with prescription sleep medication?
Consult your doctor before combining the two. Moongreens isn't a substitute for prescribed treatment.
Can I take it if I have anxiety, IBS, diabetes, high blood pressure, or take blood thinners?
Several ingredients support nervous-system wind-down and gut comfort, and KSM-66® has been studied around stress. But if you have a diagnosed condition or take related medication — including anticoagulants, given turmeric — consult your healthcare professional first.
Is it suitable for a clinical sleep disorder?
No — Moongreens isn't a treatment for diagnosed conditions like insomnia disorder, sleep apnea, narcolepsy or restless leg syndrome. See your doctor and follow their guidance.
Is Moongreens FDA approved?
No dietary supplement is — that's a category-wide fact. Moongreens is made in an FDA-registered, GMP-compliant facility and complies with FDA dietary-supplement regulations. These statements have not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.
Is it NSF Certified for Sport?
Certification is in progress. The current batch does not carry the mark; the next batch, expected before the end of 2026, will. We'll update packaging and customers when it's confirmed.
Will it show up on a drug test?
No ingredient in Moongreens is a prohibited substance under WADA, USADA or standard workplace panels. NSF Certified for Sport — which specifically tests for banned substances — is in progress for the next batch.
Is it third-party tested?
Every batch is third-party tested for heavy metals, microbials and gluten against established safety limits, and it's produced in an FDA-registered, GMP-compliant facility. COAs are available on request. NSF Certified for Sport testing is in progress for the next batch (expected before end of 2026).
The 90-night guarantee & returns
What is the 90-night guarantee?
Start on any subscription and if Moongreens hasn't changed how you sleep by night 90, you get a full refund — no return needed, no questions. It's 90 nights because that's the honest timeline: the adaptogen stack takes 6–8 weeks to reach full effect, so a 30-night window would ask you to judge it before it's worked.
Is the guarantee available on one-time purchases?
No — it covers subscription orders only, not one-time purchases. Any subscription plan qualifies, so if you want the guarantee, start on a subscription rather than a single bag.
How do I claim it?
Email support@moongreens.com within 90 nights of your first subscription order with your order number. We process a full refund — no return required.
How long do refunds take?
Within 5–7 business days of approval, back to your original payment method.
My order arrived damaged or incorrect.
Email support@moongreens.com with your order number and a photo. We reship immediately at no cost — no need to return the original — whether you're a subscriber or a one-time buyer.
The guarantee sounds too good — is it real?
It's real and has been honored since launch. It only makes commercial sense if the product works, which is the point.
Subscriptions & billing
What does it cost?
One-time: $99 for a one-month bag. Subscribe and the rate is $89.10/month for a monthly bag, or $237.60 every 3 months for the 90-night plan — the best value, with a free starter kit and sleep mask included. Standard US shipping is always free. Current options are on the product page.
Why subscribe rather than buy one bag?
One bag is 30 nights — enough for early effects, not enough to judge the adaptogen stack. The 90-night plan runs the full protocol, ships free, earns store credit, and carries the 90-night money-back guarantee, so the financial risk is lower than a one-time purchase.
Is there a minimum commitment?
Two subscription orders before you can cancel — stated clearly at checkout. After your second order is processed, cancel anytime, no fees.
Can I cancel?
Yes, after your second subscription order. Log in at moongreens.com, open the subscription portal, and cancel in two clicks — no phone calls, no restocking fees, no penalties.
Is this a subscription trap?
No. The two-order minimum is disclosed at checkout; after that you cancel in two clicks from your portal. No hidden charges, no surprise renewals, no barriers.
Can I pause or skip a delivery?
Yes — both from your portal. Skip the next order, or pause for up to 3 months without canceling. For a longer pause, email support@moongreens.com.
Can I change my plan?
Yes — update it in your portal at moongreens.com, or email support@moongreens.com.
When does my subscription renew, and will I be warned?
Your renewal date is set from your first subscription order, and shifts if you skip or delay. You get an email reminder before every renewal so you have time to adjust.

Company & values
Who founded Moongreens?
James Higgins — a British entrepreneur with a decade in banking (Lloyds, RBS) before building Moongreens. He built it after years of poor sleep as a high performer: tried melatonin, watched it fail, researched the science, and made the product he couldn't find. He's reachable at james@moongreens.com.
Is Moongreens owner-operated?
Yes. James runs the business directly — when you contact Moongreens you're dealing with a lean, founder-led team, not a faceless corporation.
Where is it made?
Made in the USA — Allen, Texas — in an FDA-registered, GMP-compliant facility, and fulfilled from Hebron, Kentucky. Midnight Atlas Inc, a Delaware C-Corporation, operates the brand.
Why is it only available direct, not on Amazon or in stores?
Selling direct means controlling quality, pricing and the relationship end-to-end — and it's how the guarantee, the subscription model and personal support are even possible. It's deliberate, and it isn't on Amazon.
Is it cruelty-free and sustainable?
Yes — entirely plant-based, no animal testing, sustainable bag materials, and made in the USA. More sustainability work is in development.
How do you handle my data?
As described in the privacy policy — used to process orders, manage subscriptions and communicate with you, and not sold to third parties.
Can I invest in Moongreens?
A community investment round is planned for 2027. Email invest@moongreens.com to register interest and James will be in touch when it opens.
How do I contact support, and what are the hours?
Email support@moongreens.com or use the chat on any page. The assistant handles most queries instantly, 24/7; a human responds within one business day. Press inquiries: press@moongreens.com.
Sleep science
Why do I wake up at 3am?
Almost always cortisol. It naturally rises before waking; when it's dysregulated by chronic stress or late work, that rise comes earlier and sharper, pulling you out of deep sleep. The fix is addressing cortisol, not forcing sedation — more here.
What is cortisol's role in sleep?
It's bidirectional: high evening cortisol blocks deep-sleep initiation, and poor sleep raises the next day's cortisol — a compounding loop. Breaking it is central to how Moongreens works. Background here.
What is sleep architecture?
Sleep runs in roughly 90-minute cycles of light, slow-wave (deep) and REM sleep. Total hours don't equal recovery — time in deep and REM does. That's why you can sleep eight hours and still feel wrecked. More here.
What is slow-wave (deep) sleep?
The most physically restorative stage — growth hormone release, muscle repair, immune strengthening, and brain waste clearance. It happens mostly in the first half of the night and is reduced by cortisol, alcohol and poor timing.
What is REM sleep?
The stage tied to dreaming, memory and emotional processing, mostly in the second half of the night. Alcohol, some medications and fragmentation cut it. More here.
What is the glymphatic system?
During deep sleep, channels in the brain widen and cerebrospinal fluid flushes metabolic waste, including amyloid beta. Chronic light sleep means that clear-out keeps failing — the brain fog is literal. More here.
What's the gut-sleep connection?
About 90% of serotonin — the precursor to melatonin — is made in the gut, so gut inflammation impairs melatonin signaling. Moongreens supports both sides. More here.
How does alcohol affect sleep?
It helps you drop off but suppresses REM and causes rebound waking in the second half of the night — fragmented, unrestorative sleep. More here.
What's the deal with caffeine and sleep?
Caffeine blocks adenosine — the molecule that builds sleep pressure all day. With a 5–7 hour half-life, an afternoon coffee is still working at night. Full explainer here.
What is adenosine?
The chemical that accumulates while you're awake and creates the drive to sleep. Caffeine masks it rather than clearing it — which is why coffee keeps you up without making you rested. More here.
What is sleep debt — can I repay it?
The cumulative gap between the sleep you need and what you get. It's only partially repayable, and the cognitive costs persist past a weekend lie-in — consistent nightly quality beats occasional catch-up. More here.
What is HRV and why does it matter?
Heart Rate Variability reflects the balance between your stress and recovery nervous systems; higher HRV in sleep means better recovery. Stress, poor sleep and alcohol suppress it — many subscribers track it on Oura, Garmin or Whoop.
What is the circadian rhythm?
Your roughly 24-hour internal clock, set mainly by light — morning light raises cortisol, darkness triggers melatonin. Late screens, irregular times and shift work degrade sleep across every stage. More here.
Does poor sleep really affect performance?
Significantly. Six hours a night for two weeks produces impairment equivalent to two full nights without sleep — and people lose the ability to notice their own decline. More here.
Better sleep,
starting tonight.
One scoop. 90 nights. Full refund if it doesn't change how you sleep — subscription only.
