Our Story

Driven by the silent struggles I saw...

Hey all.
I’m Castro Clive, an educator turned femtech founder.
I didn't set out to build a wellness brand. I come from education — helping people find their footing, their readiness, their next step. Byond started somewhere quieter.
I watched a woman who raised me go from monthly pain she just learned to carry, to years of perimenopause and menopause that nobody around her seemed equipped to explain, let alone ease. She didn't complain much. She just adjusted — the way a lot of women are taught to. Around the same time, someone I loved went through her own version of that pain, dismissed in the same familiar way: this is normal, just manage it.
What stayed with me wasn't the pain itself. It was the silence around it. Two women I loved, a generation apart, both essentially unheard by the systems meant to help them — handed the same vague advice, expected to just get on with it.
So I did what I know how to do: I went looking for what should already exist. And I kept finding the same gap — supplements that treated "women's health" as one generic category, when in reality a woman's body asks for entirely different support at 16, at 30, at 50. Nothing was built for the actual arc of a woman's life.
Byond is what I wished had existed for both of them — a wellness brand that meets women at each life stage, honestly and specifically, instead of offering one catch-all fix and calling it enough. From The Flow to The Pause, every product exists because a real stage of life demanded it, not because it looked good on a shelf.
My career has spent years in education and EdTech, in sales, in building relationships around people the system tends to overlook. That work taught me the same lesson twice over: the biggest gaps aren't always the loudest ones, they're the ones everyone's quietly adjusted to. Spotting that gap, and building something patient and specific enough to actually close it, is the part of the job I already knew how to do.
I'm not a doctor, and I didn't come from healthcare. But I know what it looks like when someone you love is in pain and has nowhere real to turn. That's reason enough to build something better. So this is my journey altogether.

As a man, I didn’t build this company to speak for women - I built it to listen to them, learn from them, and put their wellness exactly where it belongs: first…

Core mission

Women’s health, finally first

For too long, women’s wellness has been an afterthought — products adapted from male-centric research, under-dosed, over-marketed, and under-delivered. We exist to change that.

Byond Biocare is built on a single principle: every woman deserves supplements that reflect her biology, her stage, and her reality. Not a diluted male formula with a pink label.

Our mission is to make clinical-grade, women-specific nutrition accessible, honest, and beautiful — at every chapter of life.

Lab research

Science & sourcing

The science behind Byond

◆
Peer-reviewed foundation

Every formula begins with a systematic review of published clinical literature. We only include ingredients with statistically significant outcomes in randomised controlled trials.

◇
Therapeutic dosing

We match the exact doses used in the studies — not trace amounts added for label appeal. If the evidence says 400mg of magnesium glycinate, that’s what’s in the capsule.

◦
Third-party testing

Every batch is tested by NSF International for identity, potency, and purity. Certificates of analysis are published on our website for every product, every batch.

◎
Traceable supply chain

We know the origin of every raw ingredient. Our suppliers are audited annually. KSM-66 Ashwagandha, marine collagen, methylated B-vitamins — sourced with full traceability.

△
Clinical advisory board

Our formulas are reviewed by an independent board of OB/GYNs, endocrinologists, and registered dietitians with expertise in women’s hormonal health before any product launches.

□
Clean label standard

No titanium dioxide. No magnesium stearate. No synthetic fillers or binders. Just active ingredients, capsules, and nothing else. We publish the full label before you buy.

Brand values

What we stand for

01
Radical transparency

Every ingredient, every dose, every supplier — published without exception. If we can’t show you exactly what’s in it, we won’t sell it.

02
Science without compromise

We follow the evidence wherever it leads. No trend ingredients, no marketing-driven formulations, no shortcuts that sacrifice efficacy for cost.

03
Designed for her

The female body is not a variation of the male body. Our formulas are built from the ground up for women’s physiology, hormonal rhythms, and life stages.

04
Planet conscious

B-Corp certified. FSC-certified packaging. Carbon-neutral shipping. We believe caring for women’s health and caring for the planet are the same mission.
