Mood regulation chemicals are the brain’s messengers that balance how we feel, think, and respond to daily life. Serotonin, dopamine, norepinephrine, GABA, glutamate, endorphins, and endocannabinoids all work together to shape mood, motivation, and stress responses—and they are deeply linked to the gut-brain axis. Emerging science shows the gut microbiome can influence the production and signaling of these mood regulation chemicals, creating a direct pathway from what you eat and how you sleep to how you feel. To support steady mood regulation chemicals, adopt science-backed habits around nutrition, sleep, light exposure, and daily routines. Nutrition matters: prioritize fiber-rich plant foods to feed beneficial microbes, include protein sources that provide tryptophan and other precursors for serotonin and dopamine, and add omega-3 fats from fish or flaxseed. Fermented foods and polyphenol-rich fruits and vegetables can also support a balanced microbiome. Sleep regularity is key—consistent bedtimes, a calming pre-sleep routine, and minimizing light exposure at night help melatonin and sleep architecture. Morning light exposure helps calibrate circadian rhythms for daytime alertness, while staying active and hydrated supports stable signaling pathways behind mood regulation chemicals. With InnerBuddies, you can translate this science into action. InnerBuddies offers a white-label Gut Health Operating System that powers gut microbiome testing programs for brands and organizations, while also serving direct-to-consumer needs. Core features include a Gut Microbiome Health Index on a 0–100 scale, a top 40 bacteria panel with healthy-cohort comparisons, and categorized bacterial functions labeled as positive or negative—so you can see how your microbiome stacks up against health benchmarks. Target Group analysis dives into specific populations—Healthy Aging, Endurance or Power Sport, Skin & Hair Health, and more—so guidance can be tailored to real-life goals. A personalized nutrition plan and personalized probiotic/prebiotic recommendations are crafted from your unique gut profile and a 3-day food diary dataset.
