The hashtag #GutTok has over 6 billion views on TikTok, the global digestive health product market is worth over $60 billion, and viral trends that promise to “hack your gut” through miracle products, cleanses, and restrictive diets are all the rage.

We have a symbiotic relationship with all of those little guys; we keep them well-fed and they produce substances that can benefit our body and brain.
