Your gut health plays a massive role in how your brain feels. Inflammation can disrupt tryptophan — an amino acid needed to make serotonin and melatonin. Instead of supporting mood and sleep, it can get shunted down the wrong pathway, producing neurotoxic metabolites like quinolinic acid.

Without enough stomach acid, enzymes, and B vitamins (especially B6), serotonin levels drop, leading to anxiety, mood swings, and brain fog. Add in high cortisol from stress, and both your gut barrier and blood brain barrier can weaken, creating even more problems.

This is how gut issues, nutrient absorption, and stress hormones all connect to neurotransmitters and mental health.
