90-Night Money-Back Guarantee
Try it for 90 nights. If you don't sleep better, we'll refund every penny. No questions.
Named clinical forms — not a proprietary blend
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, or four purchases
To match a single nightly scoop of Moongreens, you'd be stacking a magnesium supplement, a sleep aid, a greens powder, and a probiotic. Here's where they overlap, and where they don't.
Comparison reflects typical mass-market products in each category. Formulations vary.
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.

Ashwagandha (KSM-66®)
Stress & Nervous System Support
An adaptogenic herb traditionally used to help the body manage stress. Supports a balanced stress response and promotes a calmer state before sleep. When cortisol drops at the right time, deep sleep has room to engage. KSM-66® is the most clinically studied form of ashwagandha root extract available.
-
Magnesium Bisglycinate (Albion®)
Deep sleep & Muscle Recovery
A highly bioavailable form of magnesium that supports nervous system balance and muscle relaxation. Helps create the conditions for deeper, more restorative sleep and overnight recovery. The bisglycinate chelate form is absorbed significantly better than standard magnesium oxide.
-
Inulin from Chicory Root (Fibruline®)
Gut Health & the Sleep Connection
Most sleep products ignore the gut entirely. Fibruline® is a certified organic prebiotic fibre that feeds the beneficial bacteria your gut needs to produce serotonin — the precursor to melatonin your body makes naturally. Better gut environment, better sleep chemistry.

Everything you need before you decide.
The most common questions, answered plainly. Something not covered? Email hi@moongreens.com. We reply the same day.
Does Moongreens contain melatonin?
No. Moongreens has no added melatonin. Melatonin is a hormone, not a nutrient, and we don't add it.
Griffonia seed extract is a natural source of 5-HTP, which sits upstream of serotonin and, from there, your body's own melatonin. The formula supports that pathway and leaves the hormone itself to your body.
What are the key ingredients and what does each one do?
The formula works across four areas that sleep products usually treat separately, or skip.
Evening wind-down: KSM-66® Ashwagandha is an adaptogen, included for the stress side of sleep. L-Theanine, lemon balm and chamomile (apigenin) sit alongside it, with GABA and L-Glycine rounding out the wind-down.
Gut and serotonin pathway: Griffonia seed extract (a natural source of 5-HTP) feeds the serotonin pathway. ProbioSEB® CSC-3 is the probiotic, Inulin (Fibruline®) is its fuel, and BioPerine® is included to support absorption across the blend.
Greens and antioxidants: organic spirulina, tart cherry, turmeric, ginger extract, and a whole-food greens and berry blend of wheatgrass, spinach, broccoli and blueberry.
Micronutrients: Albion® Magnesium Bisglycinate Chelate, zinc bisglycinate, vitamins C, D and B-complex (B1, B3, B6, B12), iron, and pink Himalayan salt.
The full Supplement Facts, with every named form, are on the product page. No proprietary blends.
Will it make me groggy in the morning?
Moongreens isn't a sedative and it isn't built to knock you out. It works on the evening side of the picture: winding the nervous system down and supporting your own sleep chemistry through the 5-HTP pathway.
Everyone responds differently, so we can't promise how you'll feel in the morning. If you find you wake up feeling off, try taking it earlier in your wind-down window, give it a couple of weeks, and email hi@moongreens.com. We'd like to hear about it.
Will I become dependent on it?
Moongreens is a food-based formula. It isn't a sedative or a hormone, and it isn't designed to be something your body needs in order to sleep.
You may notice your evenings feel different while you're using it consistently, and notice that if you stop. That's the routine doing its job. If you have concerns, talk to your doctor.
Is it safe to take every night?
Moongreens is designed for nightly use. It's made in the USA in an FDA-registered, GMP-certified facility, 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 is the one to raise if you're on an SSRI.
What does it taste like?
Natural Berry & Citrus, with a mild herbal note from the botanicals. We built the blend with a world-class flavor house, because a night drink only works if you'll reach for it.
Mix one scoop with 10 to 14 fl oz (300 to 400 ml) of cold water. It works well over ice, and a squeeze of lemon brightens it if the herbal note isn't for you.
When should I take it?
Up to two hours before bed, as part of your wind-down. Same window each night is easier to stick with than a perfect one.
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 crossing time zones, the jet lag calculator shows how to shift your sleep window around the new zone.
Is it vegan, gluten-free and dairy-free?
Yes. Moongreens is vegan, gluten-free, dairy-free and non-GMO, and made in the USA in an FDA-registered facility. The full ingredient list and allergen statement are on the product page.
Can I take it with other supplements or medication?
Common supplements like vitamin D, fish oil and protein sit fine alongside Moongreens. Be more careful with sedatives, anti-anxiety medication, antidepressants (particularly SSRIs, which act on serotonin pathways), blood thinners and thyroid medication.
If you take any prescription medication, check with your doctor first.
When will I actually notice something?
Some people feel their evenings are calmer within the first week or two. Others take longer. Results vary from person to person, and a nightly routine is easier to judge over weeks than over days.
If it doesn't feel different at week two, that's normal. Give it a proper run.
Nothing's happening in the first few weeks. Should I stop?
Keep going for now. A few weeks is a short test of a nightly routine, and plenty of people take longer to settle into it.
Two things help: take it in the same window every night, and give it a proper wind-down, with dim light and no screens for the last 30 minutes. The formula supports your routine. It doesn't replace one.
If you reach night 90 on the quarterly plan and haven't noticed a difference, the 90-night guarantee gets you a full refund, no return required.
Why 90 nights? That's a long time.
Because 30 nights is a short window to judge a nightly routine, and we would rather you had time to judge it properly than decide in a month.
The formula works through stress, gut and nutrient support, none of which flip a switch overnight. A fair test is a full 90 nights of consistent use, and that's what the guarantee covers. More on how the formula works.
Does it need to be taken every night?
It's built as a nightly routine, so consistency matters more than anything else. Missing the odd night won't undo anything, but the more irregular the use, the harder it is to tell what it's doing.
Treat it like brushing your teeth. The routine is part of how it works.
Can I use it while traveling across time zones?
Yes. The Starter Kit includes a 3oz travel tub that snaps inside the shaker, holds about a week's supply and is carry-on friendly. For timing, use the jet lag calculator. It takes your departure and arrival times and shows how to shift your sleep window around the new zone.
What are the subscription options and pricing?
Quarterly (every 12 weeks): $70/bag. 30% off the one-time price. Includes the 90-night guarantee and $100 in free gifts with your first shipment: the Starter Kit, sleep mask and Dad Cap. This is the plan built for a full 90-night run.
Monthly (every 4 weeks): $80/bag. 20% off. Includes the same $100 in free gifts with your first shipment, and you can cancel any time. Suits you if you want to start with one bag at a time.
One-time purchase: $100. No free gifts and no guarantee. A fair way to try the flavor before committing.
Every subscription order also earns 2% cashback, credited automatically to your account.
Is there a minimum commitment?
No. You can cancel, pause or skip at any time through your account portal. No phone calls, and no minimum number of orders.
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.
If the portal gives you trouble, email hi@moongreens.com.
When will I be charged?
Your first charge happens at checkout. After that, charges happen automatically at your chosen interval: every 4 weeks on monthly, every 12 weeks on quarterly. You'll get a reminder email a few days before each charge so you can skip or delay.
What is the 2% cashback?
Every subscription order earns 2% of the order value back as store credit, applied automatically. There are no points to track and no codes to redeem. Credit builds with each delivery and can be used against future orders.
Can I buy without subscribing?
Yes. A one-time purchase is $100. You won't get the free gifts, which come with either subscription plan, or the 90-night guarantee, which comes with the quarterly plan, but there's no obligation to subscribe.
One bag covers 30 nights, which is enough to judge the taste and how it fits your routine. It's a shorter test than the 90 nights the guarantee is built around.
Do you have a referral program?
Yes. Refer a friend and you each get $20 in store credit when they buy. Your link and the full details 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 every payment made within that 90-night window. No return required, and the product is yours to keep. We'll ask what didn't work, and that's all.
We chose 90 nights because it's a fair test of a nightly routine, and we're happy to back that with money.
Which plan is covered?
The quarterly subscription plan only. Monthly subscriptions and one-time purchases aren't covered.
The guarantee is tied to a full 90-night run, which needs a 90-day supply. A single monthly bag doesn't cover that window.
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, and we'll process the refund from there. No return and no forms.
Are there any exclusions?
- First purchase only. Reactivated subscriptions aren't covered
- One per household (address-based)
- Quarterly plan only
- Must be claimed within 90 nights of your delivery date
- Covers payments made within your first 90 nights
Do I keep the free gifts if I claim a refund?
Yes. The Starter Kit, sleep mask and Dad Cap are yours to keep.
What's included free with a subscription?
Every new subscriber, on the monthly or quarterly plan, gets $100 in free gifts with their first shipment: the Moongreens Starter Kit ($50 value), the Moongreens sleep mask ($25 value) and the Moongreens Dad Cap ($25 value).
It's the standard subscription benefit, not a limited-time offer.
What's in the Starter Kit?
Four pieces, all stainless steel:
- 15oz shaker bottle: laser-engraved and 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, so every serving is the same
Dishwasher safe. Full details on the Starter Kit page.
What's the sleep mask?
A 3D-contoured sleep mask that blocks light without pressing on your eyelids. The molded shell holds the fabric off your eyes, so you get full darkness with no pressure on your eyes.
Adjustable velcro strap, breathable fabric, carry bag included. Navy with black trim. We tested over 100 masks before choosing this one. Full details on the sleep mask page.
What's the Dad Cap?
A dad cap with "rested." embroidered on the front.
Do I get the gifts on every delivery?
No. They ship with your first subscription order only. From your second delivery onward you receive the formula. The gifts are a first-order benefit, not a recurring item.
Can I buy the Starter Kit or sleep mask separately?
Yes. The Starter Kit is $50 and the sleep mask is $25 on their own. Subscribing is better value, since you get both, plus the Dad Cap, free with your first order.
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, and if approved your card is charged directly. No reimbursement forms.

Still unsure? That's what the 90 nights are for.
Try it on the quarterly plan. If it doesn't work for you after consistent use, you get a full refund with no return.
