The ritual is lovely. The catch most people miss: the cherry juice is doing the melatonin job — so it isn’t quite the melatonin-free fix it looks like.
If you’re comparing Moongreens vs the Sleepy Girl Mocktail, you’ve already landed on something good: a calming, alcohol-free wind-down drink instead of a pill. The mocktail — tart cherry juice, a spoon of magnesium powder, and a prebiotic soda or sparkling water — went viral for a reason. It tastes nice, it’s a pleasant end-of-day ritual, and the two main ingredients genuinely have some sleep research behind them.
So this isn’t a takedown. It’s about what the mocktail actually is once you look past the aesthetic: a two-ingredient DIY drink, mixed fresh every night, with one quiet surprise in it.
The cherry juice is the melatonin
Here’s the part that rarely gets mentioned. Tart cherry juice works partly because it naturally contains melatonin — that’s a big reason some people report vivid dreams after a few mocktails. There’s nothing wrong with that, but if you chose the mocktail specifically to avoid melatonin, the cherry route is quietly giving it back to you.
Moongreens takes a different path on purpose. No added melatonin, and no melatonin-bearing juice as the base — instead it includes 5-HTP from Griffonia Seed to support your own melatonin pathway. Same goal of better sleep; a different mechanism, and a genuinely melatonin-free one.

| Beyond relaxation | Cortisol, sleep depth, recovery, greens and gut | Tart cherry and magnesium only |
| Consistency | Same measured scoop every night | Varies with how you mix it and which magnesium you use |
| Effort | One scoop in water | Buy and mix three things every night |
| Best for | Someone who wants the whole night handled in one scoop | Someone who enjoys the ritual and doesn’t mind making it |
Keep the ritual, lose the guesswork
The best thing about the mocktail isn’t really the cherries or the magnesium — it’s the ritual. A nice drink in a nice glass, an hour before bed, instead of a glass of wine. That habit is worth keeping.
The weak points are the inputs. It’s only two actives (and one of them, magnesium, often turns up as citrate, which can loosen your gut overnight). The dosing drifts depending on how heavy your pour is. And it does nothing for the cortisol of a wired mind or the depth of your sleep. Moongreens keeps the “nice drink before bed” ritual and fixes the inputs: KSM-66® Ashwagandha and L-Theanine for stress, L-Glycine, Magnesium Bisglycinate Chelate (Albion®) and 5-HTP for sleep depth, plus a greens and gut layer — the same amount, every night, no mixing.
What this means for you
If you love making the mocktail and the ritual is half the point, keep enjoying it — just use magnesium glycinate rather than citrate, and know the cherry juice is bringing melatonin to the party.
If you want the same wind-down drink without mixing it yourself, without the melatonin, and with the layers a cherry-and-magnesium combo can’t cover, that’s Moongreens.

Try it for a full sleep cycle
Thirty nights isn’t long enough to judge a recovery formula — the adaptogens take six to eight weeks to reach full effect. So Moongreens comes with a 90-night guarantee: enough time to feel the difference in how you wake up, not just how you fall asleep. If it isn’t doing its job, you haven’t lost anything.
