Episode 476: Seasonal Affective Disorder and 3 Key Nutrients for Mood and Immune Health

Do you notice your mood dip, energy crash, or motivation fade as the days get shorter? Do winter colds seem harder to shake? Tune in as we unpack Seasonal Affective Disorder (SAD) and why seasonal changes can have a very real impact on both mental health and immune resilience. In this episode, we highlight key nutrients that support mood, stress response, and immune function, especially during fall and winter. We walk through the physiology behind seasonal mood changes—light exposure, neurotransmitters, inflammation, and circadian rhythm—and share practical food-as-medicine and supplement strategies you can actually implement. If winter tends to leave you feeling flat, foggy, or run-down, this episode offers science-backed support to help you feel more grounded and resilient through the season.
