But here's the kicker: your gut microbiome can play an important role in regulating this process. It's not just about what you eat, but how your gut bacteria interact with your body.
Research suggests that a balanced gut microbiome can enhance serotonin production, potentially influencing your mood, sleep, and overall well-being.
When considering happiness, remember that your gut might be more important than you realize!
