Your mood is more than a feeling—it’s a conversation between brain chemicals like serotonin and dopamine, sometimes referred to as the “depression chemicals” that help regulate happiness, motivation, and stress. When these signals get out of whack, mood dips, energy wanes, and resilience fades. The gut-brain axis offers a powerful clue: the gut microbiome can influence the production and function of these neurotransmitters through microbial metabolites, immune signaling, and vagal pathways. This page highlights science-backed steps to restore balance today, weaving together lifestyle choices with gut-health insights to support healthier mood patterns. To bring these ideas into practice, you can leverage InnerBuddies’ white-label Gut Health Operating System. It powers gut-health testing products with a modular platform that tracks the full picture: a Gut Microbiome Health Index scores from 0 to 100 indicating overall gut health, built on an exclusive IP deal with EAFIT University in Colombia; a list of the top 40 bacteria with comparisons to a healthy cohort; and categorized bacterial functions labeled positive or negative so you can see where your gut is helping or hindering mood-related pathways. The platform also offers Target Group analysis—from Healthy Aging and Endurance Sport to Skin & Hair Health—so you can zoom in on groups most relevant to mental well-being. You can explore the core testing offering at InnerBuddies microbiome test, and see how data translates into practical steps. On the action side, InnerBuddies provides Personalized nutrition advice based on 3-day food diaries matched to stool samples, helping tailor diet to support serotonin and dopamine pathways. There’s also Personalized probiotics and prebiotics advice aimed at aligning your gut microbiome with your mood goals. With science-backed steps such as regular physical activity, a fiber-rich and diverse diet, consistent sleep, and stress-reduction practices, you can start addressing the “depression chemicals” imbalance at the gut–brain interface. To keep momentum, you can subscribe for ongoing insights through the Gut Health Membership. Businesses and clinicians can also partner with InnerBuddies to offer this platform under a white-label solution. The same features that empower consumer testing are available to B2B partners—Target Group analysis, functional pathway scoring, and personalized nutrition plus probiotic recommendations—through our program.
