People don’t realize something is off until their focus, energy, mood, or resilience starts to slip. In this episode of The Superhuman Blueprint Podcast, Drew Griesel sits down with Gabe Dough, founder of Good Bru, to talk through the gut–brain connection and why the gut microbiome is often called the “second brain.” They break down what the gut microbiome is and how it quietly influences mental performance, stress regulation, and long-term health.

Along the way, the conversation explores how dysbiosis, microbiome diversity, inflammation and cortisol, and serotonin production in the gut affect gut health and mental health, including anxiety, depression, brain fog, fatigue, and sleep. Drew and Gabe also discuss short chain fatty acids, fiber and the gut microbiome, resistant starch, prebiotics and gut health, and spore-forming probiotics such as bacillus coagulans, sharing practical, science-backed ways to support energy, clarity, emotional balance, and overall performance.

🎧 Catch the full episode and learn how gut health and stress, gut health and sleep, fatigue and gut health, and the vagus nerve gut–brain axis influence mental clarity, emotional balance, and long-term vitality.

Show notes

Many high-performing people feel constantly tired, mentally foggy, more anxious than they used to be, or emotionally flat, even though they’re “doing the right things.” They optimize sleep, train hard, eat decently, manage their schedule, and still feel off. It’s frustrating because nothing feels broken enough to explain why they don’t feel like themselves.

What if the issue isn’t motivation, mindset, or willpower at all? What if your brain isn’t the starting point, but the downstream effect? For a lot of people, what feels like a mental or stress problem is actually coming from the gut.

In this episode, you’ll learn:

What the gut–brain connection actually is
How your microbiome influences mood, stress, and energy
Practical ways to support gut health in real life

By the end of this episode, you’ll have a much clearer framework for why your body has been giving you these signals and what to do about it without overhauling your entire life. This isn’t theory for theory’s sake. You’ll walk away with simple, realistic levers you can actually use starting now.
