Are you protecting your immune system as you age?   In this Longevity podcast episode, I am joined by Dr. Anurag Singh to discuss recent research that suggests Urolithin A, a compound derived from pomegranates and other foods, may help rejuvenate the aging immune system.    We dive into how supplementing with Urolithin A for just 4 weeks led to significant improvements in immune cell function and a reduction in biological age by an average of 2 years in middle-aged adults. We also discuss insights on dosing, combining Urolithin A with other longevity strategies, and ongoing clinical trials that may reveal even more benefits.   Dr. Anurag Singh is the Chief Medical Officer of Timeline Nutrition, a biotech company focused on discovering and developing next generation natural compounds that target improvement in mitochondrial health. He began his career in 2003 as a Resident Medical Doctor at Northern Railway Divisional Hospital in Lucknow.    Go to TimelineNutrition.com/nat10 and/or use code Nat10 for a discount.   Thank you to our sponsors for making this episode possible:                                                                                                                                                           Element Health: Use code Longevity when shopping at https://elementhealthsupply.com/discount/Longevity  to save on your orders.
