"I decided to get the guide and man am I glad I did...after finally reading the guide I did the protocol for Histamine and I am only 2 months into being consistent and almost every single symptoms I had has resolved."

GET THE GUIDE NOW

The Practical Guide to Histamine & MCAS will help you calm the constant reactivity in your body—random food sensitivities, skin flare-ups, unexplained anxiety, hormonal chaos, gut issues, racing heart, insomnia, and that awful feeling like your body is reacting to everything.

This isn’t just another low-histamine food list or generic article. If you’re here, you already know something deeper is going on—and you’ve probably already tried the usual advice without lasting relief.

This guide gives you what the internet doesn’t: a step-by-step, practical plan to stabilize your mast cells, reduce histamine, and feel safe in your own body again.

Here’s what’s inside:

✅ A clear, empowering explanation of why your body is stuck in overdrive, and why so many women hit a breaking point with MCAS in their 30s, 40s, and 50s (hint: it’s not “just anxiety” or perimenopause).

✅ Nutrition and hydration strategies that calm mast cells and help you feel grounded again, without starving yourself or living in fear of food. You’ll know exactly what to eat and how to stabilize your system first.

✅ Supplements that actually help MCAS & histamine intolerance, plus the common ones that backfire and make symptoms worse. You’ll know what to start with, how to introduce them safely, and how to support deeper healing.

✅ Exercise strategies that rebuild your energy and nervous system resilience, without triggering crashes, anxiety, or flares. Movement is key, but the right kind of movement matters more when your body is in survival mode.

✅ Lifestyle shifts and nervous system resets that help you feel calm, safe, and strong again. If your body still thinks it’s under threat, no diet or supplement will fully work. This is the missing link for so many women.

Important: You don’t have to figure this out alone. You’ll have direct email access to me (Tom) for guidance as you follow the plan. You can do this yourself, but you won’t be left guessing.

The goal? To help you feel calm, resilient, and confident again...able to eat without fear, sleep through the night, enjoy life, and live in a body that no longer feels like it’s betraying you.

And yes, you CAN get there. This guide will show you how.

I purchased the Histamine Guide a couple of weeks ago because I was struggling too much. Almost all of my symptoms are gone/ managed from the guide. Cutting caffeine even helped my hormones which was causing major dysregulation. I really wasn’t expecting this level of an improvement.  Especially so quickly. It’s like a miracle!!!

Andrea

I finally got a chance to read your Histamine-MCAS guide. It is nothing short of amazing! I can’t thank you enough. It is written so clearly and while very thorough, it’s written in a way that everyone can understand. It’s going to be a huge hit and I am so honored you shared it with me to try and help me.

Brandi

I started following Tom's posts a few months back and I actually was sending to my sister in law also. I am 41 and a lot of his posts resonated with me and what I felt like was the start of perimenopause symptoms. I decided to get the guide and man am I glad I did... after finally reading the guide I did the protocol for Histamine and I am only 2 month into being consistent and almost every single symptom I had has resolved. No more random flushing or tingling. It was so easy to follow and the immediate steps I took began to resolve quickly... it kept me going knowing I was seeing a difference. Looking forward to a few more months down the road and feeling 100% thank you so much for the awesome guide, it has blessed me!
