Founding batch ships December 2026. 90-day money-back guarantee.
“I am now 27 weeks pregnant. I highly, highly, highly recommend Terrain.”
“I am now pregnant with a baby boy, and I super highly recommend Terrain.”

90-day guarantee
If it is not right for you, you get your money back.
From the doctors behind Fertility Avenues
Formulated with Dr. Ka and Dr. Hobson, an OB-GYN.
The formulation
Eight ingredients. Every amount shown.
Terrain is meant to sit alongside your prenatal and your doctor’s advice, not replace them.
Antioxidant nutrients
Ubiquinol (CoQ10), N-acetylcysteine and selenium are included for their roles in the body’s antioxidant systems and cellular energy production.
Everyday nutrients
Vitamin D3, zinc, L-methylfolate and omega-3 (DHA and EPA) are nutrients commonly reviewed in preconception planning. Ask your clinician how they overlap with your prenatal.
Myo-inositol
The largest ingredient by weight, at 4 g a day in two sachets. Whether it suits you is a question for your clinician.
The formula
Nothing hidden.
You have read enough labels to know what a proprietary blend can hide. Each ingredient is listed with its daily amount.
Amounts are per daily kit. Other ingredients and allergens are listed on the label.
Terrain 90-day kit, $360
About $120 a month. Ships December 2026. 90-day money-back guarantee.

Ninety days. One small thing that is entirely yours.
Whether you are just starting to try or have been trying for a while, this is a part of the process you control.
Begin
Start the daily kit and take it at the same time each day, following the directions on the label.

Keep a short log of sleep, energy and stress. Bring it to your next appointment if you like.
Stay steady
Consistency matters more than any single day.
Decide
Keep going if it suits you. If it does not, email us and we refund you.
The Fertility Avenues difference
Most fertility supplements stop at the bottle. This one comes from a program.
Dr. Ka (Antonia Ka, Ph.D., D.Sc.) has spent more than 25 years helping women prepare their bodies for conception.
Dr. Hobson is an OB-GYN with classical medical training who believes the body responds when its conditions change.
Together they lead Fertility Avenues, a coaching program built around the same terrain approach. Terrain is the daily foundation they wanted their clients to have.
For 25 years, Dr. Ka has built nutrition and supplement protocols with the women of Fertility Avenues. Terrain brings that approach to women who will never sit in her office.

Questions you are probably asking
Is this only for women who have struggled to conceive?
No. It is for any woman preparing to conceive, whether you are just starting to try or have been trying for a while.
Does this replace my doctor’s advice or my prenatal vitamin?
No. It is a daily supplement that sits alongside your medical care. Tell your doctor what you are taking, especially if you are in fertility treatment, and ask whether to take it with your prenatal.
Does the guarantee depend on getting pregnant?
No. The guarantee covers the supplement itself. If you take it for 90 days and decide it is not right for you, you get your money back.
When does my pre-order ship?
Founding-batch pre-orders ship in December 2026. If your order has not shipped by December 31, 2026, we will email you and you can cancel for a full refund.
Can I take it while I am in an IVF or IUI cycle?
Ask your clinician before starting any new supplement during treatment. Share the full ingredient list with them.
Is it safe if I am pregnant or breastfeeding?
Talk to your physician before use. This formula is designed for women preparing for conception.
