Dr. Ravi Kumar is a board-certified neurosurgeon who left the operating room to explore the questions that matter most about your health.
Listen to the PodcastEvery week, I cut through the noise of health headlines and marketing claims to bring you what the research actually says. No dogma, no agenda, just an honest look at the science that shapes how you live, heal, and thrive.
Alpha lipoic acid is sold as an antioxidant, but oral doses have a half-life of about 30 minutes and are cleared from your blood within 90, yet the effects can last for days or weeks.

A global review of 23 studies found that hotter days track with more anxiety, depression and emergency visits in children, with the largest jump during heat waves.
★★★★★"So glad I found this podcast. Dr. Kumar doesn't want you to just mask symptoms, he wants you to understand root causes and help you truly heal. He is the best of both worlds - he shares a wealth of modern medical knowledge, but also empowers the listeners to take personal responsibility for their health."
