90-Night Reset-or-Refund Guarantee

Sleep through the night or pay nothing.

Less than 1% of customers ever ask for a refund.

If your body is exhausted but your brain switches on the moment you lie down, if you wake at 3 or 4am like clockwork, or if you sleep the hours and still wake up wrecked, then your cortisol rhythm is likely the issue, and Corti was built for exactly that. It is not a sedative. It supports the evening cortisol drop your body is supposed to make on its own, so sleep stops being something you fight for.

Corti was formulated by a team of doctors and nutritionists to do one thing: reset a dysregulated cortisol rhythm. Every ingredient earns its place, dosed in the highest-quality form, with nothing along for the ride.

Sugar free. ral orie. No sedatives. Non-habit-forming.

Ingredients: KSM-66 Ashwagandha, L-Theanine, Magnesium Bisglycinate, Vitamin D3, natural fruit flavor, organic stevia. 

  1. Pour one packet into 8 to 16 oz of water.
  2. Stir or shake. A small amount of settling is normal with clean ingredients.
  3. Drink about 30 minutes before bed. Safe for daily use.

Most customers report their best results drinking Corti 30 minutes before bed, nightly, for at least two to three weeks while the rhythm resets.

Light and clean. Not salty, not syrupy-sweet. If you want something that tastes like soda, this isn't it. If you want something calm you can drink before bed without a sugar hit, it's exactly right.

It works on cortisol, the upstream cause, not just the night.

It's built for nightly use to reset the rhythm, not mask a symptom once.

No sedatives. No melatonin. No grogginess.

Only clinically studied ingredients, in the forms research actually uses.

It resets the rhythm so the results hold, instead of working only while you keep taking it.

Why You're Exhausted But Still Can't Shut Off

Most women assume they're simply stressed, getting older, or not managing their schedules well enough.

But that doesn't explain why you're exhausted all day...

...then suddenly wide awake the moment your head hits the pillow.

The truth is that chronic stress can keep your cortisol rhythm elevated long after the day is over.

Your body is begging for rest.

Your brain never receives the signal.

Over time, this creates a state many women describe as wired but exhausted.

You feel tired constantly, yet true rest never seems to arrive.

The frustrating part?

After living this way for years, it starts to feel normal.

You've Forgotten What a Powered-Down Body Actually Feels Like

Most women reading this have been wired-but-exhausted for so long it feels normal. Body drained, brain running, emotionally on a hair-trigger. That isn't your personality. It's a cortisol rhythm that never gets to fall. Here's what changes when it finally resets:

Reviewed by our medical advisor:

"Corti works on cortisol rhythm, which is the upstream driver most sleep products ignore entirely. And it does it without sedation, which is the direction this category should have gone years ago."— Dr. Dara K

The Four-Signal Cortisol Reset

Each ingredient targets a different stage of the same cortisol loop, in order. Not a pile of ingredients. A sequence that walks your nervous system from "still on alert" to "safe to rest."

KSM-66 Ashwagandha

SIGNAL 1 · CHEMICAL

Helps bring down the chronically elevated cortisol baseline at the level of the HPA axis. The first domino.

L-Theanine

SIGNAL 2 · MENTAL

Promotes the calm-focus brainwave state instead of the anxious-processing loop, so the racing thoughts stop without sedation.

Magnesium Bisglycinate

SIGNAL 3 · PHYSICAL

Crosses into your nervous system, where oxide can't, to support the physical relaxation that lets the body let go.

Vitamin D3 

SIGNAL 4 · RHYTHM

Supports the broader regulation that holds a healthy cortisol pattern across days, so one good night becomes the new normal.

30,000+ Women Finally Stopped Fighting Their Own Nervous System.

The symptoms looked different. The mechanism was the same.

  • "My Brain Finally Has an Off Switch."

    I've led marketing teams for eleven years and my brain would not shut off at night. By day 10 on Corti, the mental loop just stopped starting. My Oura recovery went from 61 to 86 in the same month.

    Sarah K.

  • "Off Melatonin After Three Years. Finally Sleeping."

    I had a full nightstand protocol — melatonin, magnesium, half a prescription every night. Six weeks in, the nightstand is clear. My body actually agrees it's time to stop now.

    Rebecca M.

  • "Seven Years of 3am. Gone Overnight.."

    I had normalized 3am waking so completely I stopped calling it a problem. same day I tried Corti, I slept straight through for seven hours and twelve minutes. Deep sleep up 51 minutes — I hadn't had a dream in years.

    Christine L.

  • "I Was the Last Person Who Expected This to Work."

    I'd tried melatonin and built tolerance in two months. Tried prescription sleep aids — the mornings were worse. Ten days on Corti and the 3am waking stopped. I'm recommending this more than I've recommended anything in years.
