Caryn Johnson
Founder's Take

Guessing. Bonded.

I built BOND because I was tired of being told my symptoms were normal. They weren't. And the science backs that up.

The Science Behind the Supplements

Every ingredient, researched. Every formula, intentional.

A 2020 meta-analysis in Gynecological Endocrinology found that myo-inositol significantly improved ovulation rates and hormonal profiles. BOND uses the clinically studied 40:1 ratio of myo to d-chiro-inositol.*

A randomized, double-blind, placebo-controlled study published in the Journal of Evidence-Based Complementary & Alternative Medicine found KSM-66 reduced serum cortisol levels by 27.9% over 60 days.*

Up to 40% of women carry MTHFR variants that impair folic acid conversion. BOND uses pre-methylated 5-MTHF to ensure bioavailability regardless of genetic makeup.*

BOND's 4-in-1 Female Probiotic contains L. rhamnosus, L. acidophilus, L. reuteri, L. crispatus, and L. plantarum — the same species that naturally populate a healthy vaginal microbiome.*

Research published in Fertility and Sterility showed CoQ10 supplementation improved egg quality markers in women over 35 undergoing IVF.*
