“Slept straight through to 6am for the first time in two years. I’m on my third subscription now.”
“I’d given up on sleep supplements. This one I actually look forward to drinking — and somehow that’s the one that worked.”
“My doctor told me to stop melatonin. Found this instead — actually works, no grogginess. By night 14 I realized I hadn’t woken up once.”
Every ingredient
earns its place.
No fillers. No proprietary blends. Every compound dosed for a reason.
One drink.
60 seconds.
No blender. No prep. Just add water and let the science do the work.
Pour one sachet into 8–10 oz of cold or room-temperature water. Hot water works too — it becomes a calming evening tea. Tastes like a crisp blackberry lavender lemonade — lightly sweet, slightly floral, never medicinal.
⏱ 10 secondsGive it a quick stir until dissolved. Drink it 30–60 minutes before bed — this gives glycine and L-theanine time to take effect.
🌙 30–60 min before bedYou wind down more easily, sleep comes faster, and you stay there. Most customers notice a difference within the first 3–5 nights.
✓ Results in 3–5 nightsWhy people who run hot
rarely get truly restful sleep.
Sleep researchers have long studied the connection between running warm at bedtime and disrupted sleep quality. For people who run hot, that discomfort keeps you in lighter, more restless sleep — or pulls you awake at 3am.
Real results.
Real customers.
Based on feedback from 237 verified customers and a 30-night satisfaction survey of 57 early reviewers, some of whom received complimentary product. Individual results may vary.
Built for people who sleep hot — by someone who was one.
"I kept waking up at 3am, hot and wide awake, for years. I tried every sleep supplement on the market. Nothing kept me asleep. When I learned that body temperature — not stress, not anxiety — was the real reason most people wake up in the middle of the night, I couldn't find a single product specifically formulated to fix that. So I built one."

“My husband bought this for me after I’d been waking him up tossing and turning every night. I thought it was a gimmick. Three weeks later he’s stopped complaining.”
“I track sleep with an Oura ring and the data doesn’t lie. Deep sleep is up, wake-ups are down. Whatever’s in this works for me.”
“Six months in. Still works. No tolerance buildup, no side effects. It’s quietly become the one supplement I refuse to run out of.”
