The quiz pinpoints your root cause, then Kai formulates around it. Each card below shows a key ingredient Kai might include — your real pack comes from your answers.

CoQ10 · Ubiquinol Egg energy
Fuels the mitochondria inside each egg for healthier maturation.
NAC Antioxidant
Calms the oxidative stress that ages developing follicles.
Myo-Inositol Ovulation
Restores ovulatory rhythm and insulin sensitivity.
Omega-3 · DHA/EPA Anti-inflammatory

Vitamin D3 + K2 Hormone signal
Foundational for progesterone and immune balance.
Methylfolate Methylation
Active folate for DNA synthesis and a healthy start.
Root cause categories

Your pack targets the real issue.

The quiz identifies which of these areas needs the most support. Your pack is built around your result — not a one-size-fits-all formula.

Egg Quality
Hormone Balance
PCOS
Stress & Sleep
Prenatal Prep
Recurrent Loss
Kai · sample read

“Your markers point to oxidative stress on egg quality. I’m building your pack around CoQ10, NAC, and targeted antioxidants.”

The difference

Generic vitamins
guess.

Yours are formulated.

A drugstore aisle can't know what's holding your fertility back. Conceivable starts from your data — then keeps getting smarter the longer you're on it.

1
Off the shelf
One formula for everyone

Generic prenatals pick the lowest-risk dose for an average that isn't you — and hope it helps.

2
Formulated
Built from your root cause

Your quiz, tongue scan and cycle data point to the real issue. Your pack targets that — at clinical doses.

3
In the app
Kai goes deeper every cycle

Connect the app and Kai watches how your body responds, then fine-tunes the formula as you change.

“Your last cycle ran smoother and your HRV recovered — so I'm easing your inositol and adding magnesium tonight. Your pack just changed with you.”

Built by a clinician

Not a supplement company
that hired a doctor.

It's a clinical system that became a supplement company. Kirsten Karchmer spent 20+ years in fertility practice — reading cycles, symptoms, and nutrient responses across thousands of patients. Your pack is built on that, not a marketing brief.

Early stories from our founding members

“I'd been throwing money at random prenatals for a year. My pack actually targeted my low progesterone — first regular luteal phase in ages.”

Maya R.
On her pack 4 months

“One pouch a day instead of five bottles on my counter. And it changed after my last cycle without me doing anything. Genuinely felt seen.”

Priya S.
PCOS pack

“Used my FSA, so it was cheaper than the drugstore versions I was guessing at. Wish I'd found this two years ago.”

Jordan K.
Egg quality pack
Try it for 60 days, risk-free.

Give your pack a fair two months. If you don't feel the difference, we'll refund every penny — and you keep what's left. The only risk is another month of guessing.

Before you ask

Questions,
answered.

Still unsure? Our team replies in under a day — and a real clinician reviews every pack.

What if it doesn't work for me?+

You're covered by our 60-day money-back guarantee. Take your pack daily for two months — if you're not happy, email us and we'll refund you, no questions and nothing to return.

When will it ship, and is shipping free?+

Shipping is always free. Your pack is assembled and ships within about a week, and you'll get tracking the moment it's on the way. We currently ship across the continental U.S.

Is this a subscription? Can I cancel?+

Your pack refills monthly so you never run out mid-cycle, but there's no lock-in. Pause, skip, or cancel anytime in a couple of taps — no calls, no fees.

How does HSA / FSA payment work?+

At checkout you can pay with your HSA/FSA card through our partner Truemed. Most members save roughly 30% with pre-tax dollars. If you're not eligible, you can use any card.

Do I need the app or the Halo Ring to buy?+

No — your pack is yours to take on its own. The app is free and unlocks the part where Kai watches your response and fine-tunes the formula each cycle, but it's entirely optional.

What if my needs change?+

That's the point. Retake the quiz or connect the app anytime and your next pack updates automatically. You're never stuck with a formula that no longer fits.

Is it safe and high quality?+

Every ingredient is third-party tested and made in cGMP, FDA-registered facilities. No fillers, dyes, or proprietary blends. Always check with your provider before starting any supplement.
