In this Impact Wellness podcast episode, host Daria interviews Dr. Deanna Minich, a scientist and practitioner, to explore melatonin beyond its traditional role as a sleep hormone. Dr. Minich explains that melatonin functions as a chronobiotic, a potent antioxidant and anti‑inflammatory agent, and may be considered a nutrient similar to vitamin D. She discusses how melatonin is present in plants and foods, the age‑related decline in endogenous production (especially around perimenopause), and the concept of “melatonin deficiency” contributing to inflammaging and oxidative stress. The conversation covers the wide range of clinical applications—including circadian rhythm disorders, cardiovascular health, brain health, mood, gut health, eye and skin health, reproductive health, and cancer—emphasizing that melatonin’s benefits are system‑wide. Dr. Minich critiques the supplement market, noting that ~99 % of melatonin products are synthetically derived and may contain contaminants, while a plant‑cell matrix phytomelatonin called erbatonin (produced by Symphony Natural Health) shows superior antioxidant and anti‑inflammatory activity. She stresses the importance of consulting practitioners, considering drug interactions, and understanding individual metabolism (CYP1A2, sulfation) when dosing. Dosage guidance ranges from physiological low doses (0.3–1 mg) for daily use to higher doses (3–5 mg) for jet lag or specific therapeutic needs, with much higher doses used under medical supervision for conditions like cancer. The episode also addresses melatonin testing (urine, serum, saliva) and its limitations, the role of gut‑derived melatonin, hormone replacement therapy, and the impact of lifestyle factors (light exposure, blue‑light, stress, diet) on melatonin production. Finally, Dr. Minich advises against routine melatonin supplementation in children, explains the natural high endogenous levels in youth, and highlights the need to address root causes of sleep disturbances.
