90-Night Money-Back Guarantee
Try it for 90 nights. If you don't sleep better, we'll refund every penny. No questions.
HOW IT WORKS
IN STOCK · SHIPS SAME BUSINESS DAY
Backed by our 90-night guarantee: full refund if it doesn't work, no questions beyond what didn't work.
You're not bad at sleeping. You're under-recovered.
Groggy mornings and 3am wake-ups aren't really a sleep problem. When cortisol stays elevated into the evening, deep sleep doesn't fully engage — that's a mechanism, not bad luck. Moongreens is built from named clinical forms: KSM-66® Ashwagandha, L-Theanine, Magnesium Bisglycinate Chelate (Albion®), designed to work with that process instead of forcing sedation on top of it.
One scoop, mixed into your evening routine, night after night.
- Named clinical forms, not a proprietary blend. Full detail on the Supplement Facts panel
- Formulated around sleep architecture, not just hours logged
- Supports the gut-serotonin pathway (ProbioSEB® CSC-3, BioPerine®) most sleep products ignore entirely
- Built to work with your body's own recovery process, not override it
No added melatonin. 5-HTP from Griffonia Seed supports your body's own melatonin production through the serotonin pathway, instead of overriding it with a synthetic mega-dose. No dependency.
Made in the USA.

Your first 90 nights
This formula works in sequence. The calm comes first; the parts you'll care about most arrive later than week two. Here's the honest timeline.
The calming side works from night one. Some settle easier already, plenty don't yet. The slow work hasn't started.
The habit sticks. The live cultures and prebiotic settle any early gut noise as they establish.
Sleep quality compounds with repetition. KSM-66® Ashwagandha is still ramping toward the two-month mark. Stop now and you never reach it.
Better nights show up in your days. B-vitamins and minerals fill gaps that take weeks to move.
The antioxidant load builds, and vitamin C and zinc start supporting skin and hair. Slowly, because skin keeps its own schedule.
It's just your routine now. This is the point to judge it. Not week two.
Judge it at 90 nights, not week two.
That's what the 12-Week Plan is for.

One scoop replaces four supplements.
Most people don't take one sleep supplement. They stack a magnesium, a sleep aid, a greens powder, and a probiotic. Here's what that costs — and where Moongreens fits.
Cost comparison reflects typical retail prices for reputable individual supplements. Actual costs vary by brand and dosage.
Why I Built This
I spent 10 years working in financial services in London, surviving on 5 or 6 hours of sleep a night. I tried everything. Most sleep supplements either knocked me out or did nothing.
Then I spent another 5 years travelling the world while building an award-winning bedding brand — and becoming obsessed with what actually makes people sleep well.
I created Moongreens because nothing on the market was designed for people like me: high-performing, chronically under-slept, and allergic to wellness fluff.
Everything you need before you decide.
The most common questions, answered honestly. Something not covered? Email hi@moongreens.com — we reply same day.
Does Moongreens contain melatonin?
No. Moongreens contains no added melatonin. Rather than flooding your system with a synthetic hormone, it supports the pathway your body already uses to produce its own.
Griffonia seed extract is a natural source of 5-HTP, which converts to serotonin and from there into melatonin via the gut-serotonin pathway. Supporting your own production means no suppression of the feedback loop, no morning grogginess, and no dependency on an external dose.
Melatonin supplements — particularly at the doses sold over the counter — signal your body to produce less of its own. We don't think that's the right trade for a nightly supplement.
What are the key ingredients and what does each one do?
The formula covers four categories most sleep products treat separately — or miss entirely.
Cortisol and stress wind-down: KSM-66® Ashwagandha is the clinically studied adaptogen at the core of the formula — it works by reducing the cortisol load that keeps your nervous system active into the evening. L-Theanine, lemon balm, and chamomile (apigenin) support the same process without sedation. GABA supports nervous system downregulation. L-Glycine helps lower core body temperature, cueing the brain that sleep is approaching.
Gut-serotonin pathway: Griffonia seed extract (a natural source of 5-HTP) supports serotonin and sleep-cycle regulation. ProbioSEB® CSC-3 is a clinically studied probiotic complex. Inulin (Fibruline®) feeds it. BioPerine® enhances absorption across the formula.
Greens and antioxidants: Organic spirulina, tart cherry, turmeric, ginger extract, and a whole-food greens and berry blend — wheatgrass, spinach, broccoli, blueberry.
Micronutrients: Albion® Magnesium Bisglycinate Chelate (highly bioavailable), zinc bisglycinate, vitamins C, D and B-complex (B1, B3, B6, B12), iron, and pink Himalayan salt.
Full Supplement Facts are on the product page. All named forms are listed — no proprietary blends.
Will it make me groggy in the morning?
No. This is the core difference from melatonin-based sleep aids. High-dose melatonin can suppress your body's own production and shift circadian timing — that displaced, heavy feeling in the morning.
Moongreens works by calming the nervous system and supporting your own sleep chemistry, not by forcing sedation. The transition into sleep is natural rather than imposed, and the wake is cleaner — most people describe it as finishing a cycle rather than being cut short by an alarm.
Will I become dependent on it?
No. None of the ingredients create physiological dependency — your body does not adapt to require them in order to sleep. This is distinct from melatonin, where consistent high-dose supplementation can suppress your own production over time.
What you may notice is that you sleep better while using Moongreens consistently, and notice the difference if you stop. That's not dependency — that's the formula doing its job. The underlying biology it supports remains yours.
Is it safe to take every night?
Yes. Every ingredient is chosen for daily long-term use. The formula is manufactured in an FDA-registered, GMP-certified facility in the USA and every batch is independently third-party tested.
If you're pregnant, breastfeeding, under 18, or taking prescription medication — particularly SSRIs, MAOIs, sedatives, or blood thinners — check with your doctor before starting. The 5-HTP pathway specifically is worth flagging if you're on SSRIs.
What does it taste like?
Natural berry and citrus, with a mild herbal undertone from the botanicals. No bitterness, no grassy aftertaste, no fake sweetener finish.
Most people mix one scoop with 300–400ml of cold water. It works well over ice. If the herbal notes aren't for you, a squeeze of lemon cuts through and brightens it.
When should I take it?
Up to two hours before bed, as part of your wind-down. That window gives KSM-66® and the calming botanicals time to do their work before you actually need to sleep.
Consistency matters more than precise timing. Same window, every night. Some people pre-mix it in the afternoon and keep it in the fridge; others mix it fresh in the evening. Either works.
If you're travelling and crossing time zones, try the jet lag calculator — it tells you how to shift your sleep window and adjust the routine around the new time zone.
Is it vegan, gluten-free, and allergen-safe?
Yes to all. Moongreens is vegan, gluten-free, dairy-free, and non-GMO. No common allergens. Made in the USA in an FDA-registered facility.
Can I take it with other supplements or medication?
Most common supplements — vitamin D, fish oil, protein — are fine alongside Moongreens. Where to be cautious: sedatives, anti-anxiety medication, antidepressants (particularly SSRIs, which interact with serotonin pathways), blood thinners, and thyroid medication.
If you're on any prescription medication, run it past your doctor first. The 5-HTP pathway specifically is worth raising if you're on SSRIs — that's not a boilerplate disclaimer.
When will I actually notice something?
The calming side works early. Most people notice evenings feel less wired and the transition to sleep is smoother within the first week. That part doesn't take long.
The deeper benefits take longer. KSM-66® Ashwagandha reaches its full effect on cortisol and stress resilience at around six to eight weeks of consistent use. Sleep architecture — the quality of deep sleep stages — improves progressively. The probiotics need a few weeks to establish.
If it doesn't feel transformative at week two, you're not wrong — you're early. Most of what matters happens between nights 30 and 90.
Nothing's happening in the first few weeks. Should I stop?
Keep going. This is the most common early experience and it doesn't mean it isn't working. The ingredients acting on stress physiology and sleep architecture are building effects below the surface — they take weeks to move the needle.
Two things help at this stage: take it at the same time every night, and give it a proper wind-down environment — dim light, no screens in the last 30 minutes. The formula supports your biology; you still have to give it the right conditions.
If you reach night 90 on the quarterly plan and genuinely haven't noticed a difference, the 90-night guarantee gets you a full refund — no return required.
Why does it need 90 nights? That's a long time.
Because that's how long the relevant biology takes to change — not how long we want you to keep paying.
KSM-66® reaches clinical efficacy at around eight weeks in the studies. The gut microbiome — which feeds into the serotonin pathway and downstream into sleep chemistry — takes six to eight weeks to meaningfully shift with a new probiotic. Micronutrient deficiencies take weeks to correct at tissue level. None of those processes can be rushed.
The 30-day supplement industry has trained people to expect fast results from slow biology. We'd rather be upfront about it. More on how the formula works.
Does it need to be taken every single night?
Yes. The ingredients that matter most — KSM-66®, the probiotics, the micronutrients — are building effects cumulatively. Missing occasional nights won't wreck the protocol, but irregular use means the benefits plateau lower and arrive later.
Think of it less like a pill you take when you remember and more like brushing your teeth. The routine is part of how it works.
Can I use it while travelling across time zones?
Yes. The Starter Kit includes a 3oz travel tub that snaps inside the shaker — enough for a week, carry-on friendly. Timing when you take Moongreens matters for jet lag. Use the jet lag calculator — it factors in your departure and arrival times and tells you how to shift your sleep window around the new zone.
What are the subscription options and pricing?
Quarterly (every 12 weeks) — $77/bag. 40% off the one-time price. Includes the 90-night guarantee, free Starter Kit, and free sleep mask. The plan built for the full protocol.
Monthly (every 4 weeks) — $97/bag. 25% off. Includes the free Starter Kit and sleep mask. More flexible if you want a shorter initial commitment.
One-time purchase — $129. No free extras, no guarantee. Good for a single trial before committing.
All subscribers earn 2% cashback on every order, credited automatically to your account.
Is there a minimum commitment?
Yes — two deliveries. After that you can cancel, pause, or skip at any point through your account portal. No phone calls, no awkward process.
The two-order minimum exists because one bag genuinely isn't enough time to evaluate the formula. We'd rather tell you that upfront than process a refund from someone who never reached the part of the protocol that matters.
How do I cancel, pause, or skip an order?
Through your account portal. You can skip a delivery, delay your next shipment, pause for 1, 2, or 3 months, or cancel — all without contacting us. Cancellation is available once your two-order minimum is met.
If you run into anything with the portal, email hi@moongreens.com and we'll sort it.
When will I be charged?
Your first charge happens at checkout. Future charges happen automatically at your selected interval — every 4 weeks for monthly, every 12 weeks for quarterly. You'll get a reminder email a few days before each charge so you can skip or delay if needed.
What is the 2% cashback?
Every subscription order earns 2% of the order value back as store credit, applied automatically. No points to track, no codes to redeem. Credit accumulates with each delivery and can be used against future orders.
Can I buy without subscribing?
Yes. A one-time purchase is $129. You won't get the Starter Kit, sleep mask, or 90-night guarantee — those are subscription benefits — but there's no obligation to subscribe if you want to try it first.
One bag covers 30 nights. The protocol takes 90 nights to properly evaluate, so a single purchase tells you whether you like the taste and the immediate calming effects — not whether the full formula works for you.
Do you have a referral programme?
Yes. Give a friend $20 off their first order and get $20 store credit yourself when they buy. Full details and your referral link are on the referral page.
What exactly is the 90-night guarantee?
If you're not satisfied after 90 nights of consistent nightly use on the quarterly plan, we'll refund your first shipment in full. No return required — the product is yours to keep. We'll ask what didn't work, and that's it.
The guarantee exists because 90 nights is the honest minimum for the protocol to show results. We're willing to back that with money because we believe it.
Which plan is covered?
The quarterly subscription plan only, first shipment only. Monthly subscriptions and one-time purchases are not covered.
The reason is straightforward: the guarantee is tied to completing the full 90-night protocol, which requires a 90-day supply. A monthly bag doesn't cover that window, so it wouldn't be honest to guarantee it.
How do I claim a refund?
Email hi@moongreens.com within 90 nights of your first delivery. Tell us what you tried and what didn't work. We'll process the refund from there — no return, no forms.
Are there any exclusions?
- First purchase only — reactivated subscriptions are not covered
- One per household (address-based)
- Quarterly plan only
- Must be claimed within 90 nights of your delivery date
- Applies to the first shipment only, not subsequent deliveries
What's included free with a subscription?
All new subscribers receive the Moongreens Starter Kit (worth $49) and the Moongreens sleep mask (worth $29) with their first shipment — on both the monthly and quarterly plans.
$78 of kit, shipped free with your first bag. Not a limited-time offer — it's the standard subscription benefit.
What's in the Starter Kit?
Four pieces, all stainless steel:
- 15oz shaker bottle — laser-engraved, built for daily use
- 3oz travel tub — snaps inside the shaker, holds about a week's supply, carry-on friendly
- 30-day storage tub — rubber-sealed lid, keeps a full bag's supply fresh on the counter
- Measuring spoon — laser-engraved stainless, exact serving every time
Dishwasher safe. Built to last, not branded plastic that ends up in a drawer. Full details on the Starter Kit page.
What's the sleep mask?
A 3D-contoured sleep mask designed to block all light without pressing against your eyelids. The contoured shell holds the fabric off your eyes so you get total darkness without eyelid pressure during REM — flat masks that sit directly on the lids quietly suppress the rapid eye movement that characterises the stage.
Adjustable velcro strap, breathable fabric, comes with a carry bag. Navy with black trim. We tested over 100 masks before choosing this one. Full details on the sleep mask page.
Do I get the kit and mask on every delivery?
No — they ship with your first order only. From your second delivery onwards you receive the formula. The kit and mask are a first-subscriber benefit, not a recurring item.
Can I buy the Starter Kit or sleep mask separately?
Yes. The Starter Kit is $49 and the sleep mask is $29 as standalone purchases. Subscribing is the better value — you'd get both free alongside your first bag.
Is Moongreens eligible for HSA or FSA payment?
Yes, through our partnership with Truemed. At checkout, select "Pay with HSA/FSA." A licensed practitioner reviews your eligibility privately — if approved, your card is charged directly. No reimbursement forms needed.
