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
Lowers inflammation and supports a receptive lining.
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.”

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.

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.
Verified · 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.
Verified · 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.
Verified · 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.
