About Bitterroot - Raw Medicine. Honest Wellness.
I didn't start Bitterroot because I wanted to sell supplements.
I started it because I was standing in the supplement aisle at Whole Foods, holding two bottles that promised to "support hormonal balance," and I realized I had no idea what was actually in them, why those ingredients were chosen, or whether a single human being had ever tested them in a clinical trial.
I was 47. I hadn't slept through the night in five months. I was losing words mid-sentence in work meetings. I'd gained eleven pounds without changing a thing about how I ate. My doctor had told me it was perimenopause and handed me a sleep hygiene printout. My gynecologist suggested I "consider HRT" but also mentioned breast cancer risk in the same breath, which is a hell of a way to make a woman feel confident about a treatment plan.
So I did what I've done my entire career as an operations manager: I went to the source material. I pulled the actual studies. Not the blog posts. Not the influencer recommendations. The published, peer-reviewed research — the same papers the doctors and scientists read.
What I found changed everything.
What I Found
I found that your body has two estrogen receptors — and that almost everything on the market activates both of them, including the one linked to breast cancer risk. I found a Korean botanical extract, tested in three separate randomized controlled trials across three countries, that improved eight of eleven menopausal symptoms without stimulating a single breast cancer cell in safety testing.
I found that insomnia and anxiety aren't two separate problems — they're both caused by depletion of the same neurotransmitter, GABA, the brain's primary braking system. I found that every prescription sleeping pill and anti-anxiety medication works by forcing that braking system down artificially — and that your brain responds by removing brake pads, creating the exact dependency the drugs promise to relieve.
I found that your gut recycles up to 60% of your circulating estrogen through a bacterial system called the estrobolome — and that parasitic organisms destroy it. I found that garlic extract eliminated a common intestinal parasite in 72 hours in a clinical study, and that olive leaf outperformed the prescription drug in laboratory testing.
I found that your kidneys are the most estrogen-sensitive non-reproductive organ in your body — and that menopause independently degrades their filtration rate, according to a 2025 study of nearly 4,000 women. I found an Amazonian plant called "stone breaker" that was clinically tested at the exact dose I was considering, alongside the exact same magnesium and B6 combination, with a 54.5% stone-free rate.
I found that heavy metals like cadmium have a 15-30 year half-life in your body — meaning the metals you absorbed in your twenties are peaking in your tissue right as menopause removes the estrogen that protected you from them. I found a landmark study showing these metals sit on your estrogen receptors and send the wrong signal.
And I found that nobody — not my doctor, not my gynecologist, not the supplement brands, not the wellness influencers — had connected any of this. Because the research is scattered across gynecology journals, nephrology journals, neuroscience journals, gastroenterology journals, and toxicology journals that don't read each other.
Bitterroot is what happens when you put it all in the same room.
What Bitterroot Is
Bitterroot is a system of four formulas. Each one addresses a specific organ system that depends on estrogen and fails in a specific, documented way during menopause.
BALANCE addresses the receptor system — activating the estrogen receptor that provides relief without the one that carries risk.
RESTORE addresses the nervous system — rebuilding the GABA braking system that menopause, stress, and cortisol have depleted.
Parasite Cleanse addresses the gut — clearing the organisms that destroy the estrobolome, the bacterial system that recycles your remaining estrogen.
Kidney Cleanse addresses the filtration system — supporting the organ that processes 90% of your estrogen metabolites, activates your vitamin D, and quietly loses protection the moment menopause begins.
Each formula was built around published clinical research. Each ingredient was chosen because a real study, involving real people, published in a real journal, showed that it works. Where the evidence is strong, we say so. Where the evidence is limited to traditional use and preclinical data, we say that too.
We put the study citations on our blog. We include the PubMed ID numbers so you can look them up yourself. This is not an accident. It's the entire point.
What Bitterroot Is Not
We are not a pharmaceutical company. We don't make drugs. We don't claim to treat, cure, or prevent any disease.
We are not a "wellness brand" in the way that term is usually used — meaning pretty packaging over vague promises. We don't put 27 ingredients in a proprietary blend and hope something works. We don't use phrases like "supports overall wellness" as a substitute for knowing what our products actually do.
We are not anti-medicine. HRT is the right choice for some women. SSRIs are the right choice for some women. If your doctor has a plan that's working for you, we're not here to talk you out of it.
We are a research-driven supplement company built by a woman who got tired of being handed a printout when she needed answers. Every formula has a mechanism — a specific, explainable reason it works. Every ingredient has a job. And every claim we make can be checked against the published literature.
Who We Are
My name is Sarah Weston. I'm 51. I live in Nashville. I'm an operations manager for a healthcare staffing company during the day and a relentless research nerd at night.
I'm not a doctor, a naturopath, or a certified anything in the health space. I'm a woman who went through menopause, got frustrated by the lack of honest answers, and discovered that the science is actually there — it's just buried in journals that regular people don't read, written in language that regular people can't parse, and scattered across medical specialties that don't communicate with each other.
Bitterroot is my attempt to translate that science into something a woman can actually use. Formulas built on research. Explanations written in plain language. Citations you can verify. And an honest acknowledgment of what we know, what we don't know, and where the evidence has limits.
I named the brand Bitterroot because the best medicine isn't always sweet. The plants that heal — the ones used for centuries across Korean, Amazonian, Ayurvedic, and Chinese traditions — are often bitter, fibrous, unglamorous. They don't come in pastel packaging. They come from roots dug out of mountainsides and dried in open air. There's something honest about that. Something that doesn't need a marketing team to make it true.
Raw Medicine. Honest Wellness.
That's what this is.
Our Promise
Every ingredient in every Bitterroot product was selected based on published research — clinical trials, peer-reviewed studies, or documented traditional use spanning centuries. We will always tell you which category each ingredient falls into.
We will never fabricate a study. We will never imply clinical proof where only preclinical evidence exists. We will never use the word "proven" unless a randomized, controlled trial in human subjects has been published.
We will always include the citations. We will always give you the tools to verify what we claim. We believe that trust isn't built by asking you to believe us — it's built by giving you enough information to decide for yourself.
If we discover that a study we've cited has been retracted, corrected, or contradicted by newer research, we will update our materials and tell you. Science is not static. Our integrity depends on keeping up with it.
Your body already knows how to heal. It's just been given the wrong tools — or had the right tools taken away.
Bitterroot gives them back.
