Inside your body lies a vast neural network that scientists call "the second brain."
It contains over 100 million neurons - more than your spinal cord. And here's what's truly fascinating:
👉It produces 90% of your body's serotonin - the crucial neurotransmitter that regulates mood, anxiety, and mental clarity.
But this "second brain" isn't in your head at all.
It's in your gut.
This revelation could explain why so many people still struggle with anxiety and brain fog—even after trying every “traditional” treatment available.
As Dr. Michael D. Gershon, a professor of pathology and cell biology at Columbia University and author of The Second Brain, explains:
“The gut doesn't merely assist with digestion. The millions of neurons and bacteria within it are actively producing and regulating the same neurochemicals - like serotonin - that help govern our mood, stress responses, and mental clarity.”
Studies from leading institutions, such as the California Institute of Technology, McMaster University, and Harvard Medical School, increasingly show how imbalances in our gut (including the trillions of microbes that inhabit it) can influence anxiety, depression, and even cognitive function.
