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 Finnish trial of 465 screened children found that a 10-module internet CBT program with weekly telephone coaching still beat digital psychoeducation on child-reported anxiety 24 months after randomization, though the effect was modest and the parent-reported gap shrank.
A blood biomarker panel barely moved the diagnosis at specialist memory clinics, even as the same technology is being credited with a large accuracy jump in primary care.
A nine study meta-analysis of 480,479 adults links habitual stair climbing to sharply lower cardiovascular and overall death rates, but every study in it was observational.
★★★★★"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."
