In this episode of The Better Life, Dr. Pinkston welcomes back Dr. Warren Lesser from Magna Pharmaceuticals to dive deep into the science behind the "winter blues" and Seasonal Affective Disorder (SAD). They explore why many people experience a "bummer and dumber" effect during the darker months, as reduced sunlight affects not only our mood but also our processing speed, memory, and cognitive function.

The conversation highlights the critical role of neurotransmitters like serotonin, dopamine, and norepinephrine, and how a deficiency in L-methylfolate (B9) and B12 can hinder the body's ability to produce these "feel-good" chemicals. Dr. Lesser explains why traditional antidepressants often fail if the body lacks the necessary nutritional substrates to make them work. They also discuss how the De Novo Plus B12 supplement provides the high-dose, bioavailable nutrients needed to cross the blood-brain barrier and support mental health, energy, and overall longevity.
