No two are alike, which is why the supplements, herbs, and protocols that work for one person can do nothing for another. A gut microbiome test shows what's happening in yours, so you can skip the guesswork and choose foods and supplements based on your own results.
Book a free consultation and we'll talk through your symptoms, what a test could show you, and whether it's the right next step for you.
A test looks at which bacteria live in your gut and what they are likely doing, including several groups that affect your hormones, your gut lining, and how you handle certain foods.
Some gut bacteria can undo your body's work of clearing estrogen, which may play a role in heavy periods, PMS, and menopause symptoms.
Only about 30% of people in Western countries have the bacteria to turn soy into a plant estrogen linked with fewer hot flashes.
When they are, your gut lining can weaken, which has been linked with bloating and food sensitivities. The good news is that they respond quickly to the right foods.
Your gut bacteria can play a part in reactions to foods like wine, dairy, or wheat, and in why you might be low in iron or B12 even with a good diet.
A gut microbiome test doesn't diagnose medical conditions. It shows which bacteria may be contributing to your symptoms, so you know what to work on.
Tell me a little about your symptoms and what you've tried, so I can come to the call prepared.
Choose a 30-minute slot that suits you, and you'll get a confirmation straight away.
We'll go over what a test could show you. If testing makes sense for you, I'll explain how it works. If it doesn't, I'll tell you that too.
I'm Sarah Brandow, a PhD researcher at the University of Westminster studying how gut bacteria affect estrogen, and I hold an MSc in Nutrition.
My work sits between the lab and real women's lives. That means you'll hear what the research actually supports, what it doesn't support yet, and how it applies to your body, rather than another one-size-fits-all protocol.
Answer a few quick questions, then choose a time that works for you.
