Short answer: All three Sleeps formats are built on the same studied actives — magnesium glycinate and glycine. Choose The Powder if you want the full, gram-scale dose and a calming nightly ritual; The Capsule if you travel or want zero mixing and no taste; and The Gummy if you've quit every other supplement and just need something you'll actually take. The best format is the one you'll use every night.
Why the Format Matters as Much as the Formula
Here's the thing most supplement brands won't tell you: the best sleep formula in the world does nothing if it's sitting unopened in your cabinet. Consistency is what moves the needle on sleep. So when you're choosing between a powder, a capsule, and a gummy, you're really answering one question — which one will I still be taking three months from now?
All three Sleeps formats share the same foundation: magnesium glycinate, a highly absorbable, gentle-on-the-stomach form of magnesium, and glycine, an amino acid shown to help people fall asleep faster by gently lowering core body temperature. The science is the same across the board. What changes is the experience.
The Powder: The Full Ritual, Full Dose
Magnesium glycinate and glycine work best at gram-scale amounts — more than fits cleanly into a single capsule. The Powder delivers that complete formula at full dose, stirred into water 30 to 60 minutes before bed.
Best for: people who want the maximum studied dose and who like the idea of a wind-down ritual. There's something genuinely calming about making a warm or cool drink and sipping it as you power down for the night — it becomes a cue your brain learns to associate with sleep.
Keep in mind: it requires water and a minute of mixing, and it has a taste (most people grow to like it). If you're someone who finds rituals soothing, that's a feature, not a bug.
The Capsule: For Nights You're Not in Your Own Bed
The Capsule delivers the same studied actives with no mixing, no measuring, and no taste. Toss the bottle in a bag and your routine travels with you — hotel rooms, red-eyes, a friend's guest room.
Best for: frequent travelers, anyone who dislikes the taste or texture of powders, and people who want a clean, consistent dose they can take anywhere in five seconds.
Keep in mind: because capsules can only hold so much, the convenience trade-off is format-driven. For most people that's a worthwhile swap for grab-and-go simplicity.
The Gummy: The Lowest-Friction Way In
Some people have abandoned every powder and pill they've ever bought. The Gummy is designed for exactly that person: no water, no count, no taste to talk yourself out of. It's the lowest-friction entry point into a consistent sleep-support habit.
Best for: supplement quitters, people who hate swallowing pills, and anyone who knows the honest truth about themselves — that the easiest option is the one they'll actually stick with.
Keep in mind: a gummy format naturally carries a lighter load than a full powder dose. Think of it as the on-ramp to the habit rather than the maximum dose.

Can You Combine Formats?
Absolutely — and many people do. A common pattern is The Powder at home for the full ritual and The Capsule in your travel kit so you never break the streak on the road. The goal is an unbroken nightly habit, however you get there.
Frequently Asked Questions
Do all three contain the same ingredients?
They're built on the same studied actives — magnesium glycinate and glycine. The main differences are total dose and delivery format.
When should I take my Sleeps supplement?
Most people take it 30 to 60 minutes before bed, which lines up with when glycine's body-temperature effect and magnesium's calming effect are most useful.
Will these make me groggy in the morning?
Unlike sedative sleep aids, magnesium glycinate and glycine support your body's own sleep-onset process rather than knocking you out, so they're not associated with next-day grogginess for most people.
Which format is best for beginners?
If you've struggled to stick with supplements before, start with The Gummy or The Capsule for the lowest friction. If you love a routine, start with The Powder.
The Bottom Line
There's no single "best" format — there's the best format for you. The Powder maximizes dose and ritual, The Capsule maximizes portability, and The Gummy maximizes the odds you'll actually keep going. Pick the one that fits your life, and let consistency do the rest.
