5 Reasons Your Last
Supplement Didn't Work
And Why This One Will

You've already done the research. You know cortisol is the problem. You've tried magnesium. You've tried ashwagandha. Nothing stuck. Here's exactly why. And what changes at the clinical dose.

"I've tried magnesium. I've tried ashwagandha."

You wake up at 3am with your mind already going. Sunday nights feel heavier than they should. You used to have the energy to ask for help. Now you just handle everything alone.

You know something is off. You've just never had the right explanation for why what you tried didn't work.

That changes here.

Reason 01 / 05

You were taking the
wrong form of magnesium

Magnesium oxide, which is in 90% of what you'll find at CVS, Walgreens, and Target, has a 4% absorption rate. Your body cannot use it. You took it for a month, felt nothing, and concluded that magnesium just doesn't work for you.

It wasn't you. It was the form.

Magnesium glycinate is a completely different molecule. It absorbs at over 80%. It actually crosses into your cells and signals your nervous system that it's safe to come down. Under chronic stress, your body depletes magnesium three times faster than baseline. The deficiency is real. The drugstore fix wasn't.

275mg of magnesium glycinate at night. That's what an actual off switch feels like.
Reason 02 / 05

Your ashwagandha was
never dosed to do anything

The bottle you bought on Amazon or at the drugstore likely contains 150 to 300mg of an unstandardized extract that has never been in a single clinical trial. KSM-66, the only form with enough scientific backing to show measurable results, requires 600mg of a root-only standardized extract to do what it's supposed to do.

There are 24 double-blind clinical studies on KSM-66. Zero on what you were taking before.

27.9% average cortisol reduction. Measured in actual trials. Not a wellness claim. Data.

If ashwagandha never worked for you, you were taking a third of the dose you needed, in a form that was never going to produce measurable results.
Reason 03 / 05

Melatonin treats
the symptom, not the root

Melatonin became the default answer to sleep problems because it's easy, it's cheap, and it works for about three weeks. Then it stops. And you're back to square one except now your hormone system has a new dependency.

If you're waking up at 3am with your mind already running, that is not a melatonin deficiency. That is a cortisol problem. When cortisol is dysregulated, your body releases a surge of it in the early morning hours instead of at 6am. Melatonin does nothing to address that surge.

Week 1

Week 2–3
Fading
Week 4+
Back to 3am
Melatonin treats the symptom. Your cortisol is still running the whole time.
The root is cortisol. The fix has to target cortisol.
Reason 04 / 05

Good habits alone
don't lower cortisol

You work out. You eat well. You try to sleep eight hours. You might even do therapy. And you're still exhausted.

That's not failure. That's biology. When cortisol has been chronically elevated for years, it dysregulates your HPA axis, the system that controls your entire stress hormone response. Good habits support the system but they cannot reset it. Cortisol regulation requires a specific physiological intervention.

This is why high-performing women who do everything right still hit the same wall every afternoon. The input is right. The underlying system is still stuck.

Working out
Eating clean
8 hours sleep
Therapy
→ Still elevated cortisol. Still exhausted at 2pm.
KSM-66 ashwagandha at 600mg is the specific intervention. A mechanism that directly addresses the HPA axis and brings cortisol back to a regulated baseline.
Reason 05 / 05

The combo is
what makes the difference

Ashwagandha and magnesium glycinate work on completely separate mechanisms, which is exactly why they work so much better together.

Ashwagandha targets your cortisol production during the day. It brings the baseline down, stops the spike, gives your nervous system a way out of fight-or-flight.

Magnesium glycinate targets your nervous system recovery at night. It gives your body the mineral it needs to actually enter deep restorative sleep.

One without the other is half a solution. Together, over 90 days, it's a complete reset. Not symptom management. An actual reset.

◆ Our Story

I built this for my mother.
For every woman who holds
everything together.

Evens, Founder of Onyx
Evens Founder, Onyx
🖤

For the women who hold us up.

My mother. The women in my life. They are the foundation of our families — but who takes care of them? Black women's wellbeing has been invisible for too long. Not anymore.

🇺🇸

Because we deserve to be built for.

Black Americans are one of the largest markets in the US yet we are always an afterthought. Onyx was built for us first. Not adapted. Not adjusted. Built for us, from day one.

🔬

Because the industry has been lying.

Pretty gummies full of sugar. Marketing without science. We spent over a year formulating a stack that actually works. Clinically dosed, zero fillers. Not a vibe. A real transformation.

With love and purpose,
Evens

The 90-Day Reset

Month 1
Your sleep changes first
You start sleeping through the night. The 3am wake-ups become less frequent. Your body is finally getting the magnesium it's been depleted of.
Month 2
People around you notice
Your cortisol baseline is coming down. You're more present. Less reactive. Someone in your life says something is different about you before you fully realize it yourself.
Month 3
You recognize yourself again
The Sunday dread is softer. You have something left at the end of the day. The version of you who had capacity. She's back. That's the reset.

Everything You Need to Know

How is this different from what I've already tried?
Almost certainly, what you tried before was either the wrong form, the wrong dose, or both. Magnesium oxide, which is in most drugstore supplements, absorbs at 4%. Magnesium glycinate absorbs at 80%+. Generic ashwagandha contains 150-300mg of an unstandardized extract with no clinical backing. KSM-66 at 600mg is the only form that shows measurable cortisol reduction in actual trials. The dose and the form are the entire difference.
How long before I feel something?
Most women notice changes in sleep quality within two to four weeks. Cortisol regulation, the deeper shift that changes how you move through your day, takes six to twelve weeks of consistent use. The 90-day commitment is the protocol, not a sales tactic.
What if it doesn't work for me?
90-day money-back guarantee. Full refund, no questions asked. We're confident enough in the product to take all the risk so you don't have to.
Why a subscription?
The clinical evidence is clear: meaningful cortisol reduction requires consistent supplementation over 90 days or more. A subscription ensures you don't run out at week six and lose the progress your body has built. You can cancel anytime.
Is this safe during perimenopause?
Both ingredients are well-tolerated and widely used during perimenopause. If you're on prescription medication, check with your doctor first.
Why is this built for Black women specifically?
The Weathering Effect, documented by researcher Arline Geronimus, shows that chronic stress ages Black women's bodies at a cellular level differently than other demographics. Black women under chronic stress also deplete magnesium three times faster than baseline. The formulation doesn't change because of this, but the reason it matters is specific, and we don't pretend otherwise.
🛡️

Give it 90 days.
We'll take the risk.

Your nervous system took years to get here. If you don't feel less stressed, sleep better, and wake up with more energy after 90 days, we refund everything.

No questions. No hoops. No fine print.
