What if the antidepressant isn't failing because it's the wrong medication, but because the body doesn't have enough of what it needs to make serotonin in the first place?
As a pharmacist, I've filled thousands of antidepressant prescriptions. But there is a question we rarely stop to ask before increasing a dose or trying another medication: Where does serotonin actually come from? An SSRI can help the brain reuse the serotonin that is already available, but the production of neurotransmitters also depends on what is happening elsewhere in the body.
This means symptoms we identify as anxiety or depression may sometimes have more than one possible driver. Low vitamin D, iron deficiency, unstable blood sugar, poor digestion, inflammation, and an imbalanced microbiome can all influence how we feel.
In this episode, I'm joined by nutritionist, author, and speaker Dr. Oscar Coetzee. We explore the missing nutritional and biological "third leg" of mental healthcare and why mood disorders can have a lot more to do with what's on your plate than you think.
