Women's
hormonal health,
reimagined.
Bay Brands is a women-led wellness company creating thoughtful supplement formulations for perimenopause and the years beyond — the long transition that has, for too long, been treated as an afterthought.
A wellness company for the years between.
Perimenopause and beyond deserves a wellness practice built for that timeline — not a quick fix. Bay Brands creates the essential formulations to support women through hormonal transition, with the rigor, transparency, and care this stage deserves.
We believe that hormonal health is not a niche. It is the lived experience of every woman, every day — and it deserves the same investment, the same rigor, and the same respect as any other field of wellness.
Our story starts where many of these conversations do — quietly, between friends. A founder navigating her own transition, frustrated by the gap between what the research said and what was actually on the shelf. A community of women asking the same questions, and finding the same lack of clear answers.
So we started Bay Brands to bridge that gap. Not with marketing, but with formulations that earn trust the slow way — through ingredients you can verify, clinicians you can trust, and a tone that treats you like the adult you are.
How we think about women's wellness.
We believe hormonal health deserves the same rigor, transparency, and care as any other field of medicine. Three principles guide everything we make.
Backed by clinical research
Every formulation is backed by clinical trials or peer-reviewed studies. We start in the literature, not the marketing brief.
NSF certified, made in the USA
Third-party tested on every ingredient, produced domestically, gluten-free, made with organic ingredients — and no weird stuff.
Reviewed by clinicians
Products and ingredients are reviewed by a medical advisory board of physicians and registered nutritionists before they go anywhere near a shelf.
Built for the women we serve
Every choice we make — from formulation to packaging — is shaped by ongoing conversations with the women navigating this transition and the clinicians who care for them.
The Bay Brands process.
Every formulation moves through the same four stages — slowly, deliberately, and with input from women and clinicians at every step.
Listen
We start by hearing from the women experiencing the transition — what they are feeling, what isn't working, what they wish existed.
Research
Our team and advisors review the peer-reviewed literature on every candidate ingredient before it ever enters a formulation.
Formulate
We pair our research with input from practicing physicians and registered nutritionists to land on doses that are meaningful, not symbolic.
Verify
Every batch is third-party tested for purity, potency, and contaminants. Results are available, by lot, on request.
The standards every product has to meet.
Before a formulation reaches a single customer, it has to pass through a list of standards we set early and refuse to compromise on.
Clinically Backed
Trials, studies, peer-reviewed evidenceEach ingredient earns its place by reference to clinical trials or peer-reviewed studies relevant to women's hormonal health.
Traceable Ingredients
Source-known · provenance verifiedEvery ingredient is traceable back to a known supplier. We don't use anything we couldn't explain on the label.
Premium Ingredients
Quality first · no compromisesWe hold every ingredient to a higher bar than we have to. Premium quality is the floor, not the ceiling.
