This week, Dr. Kahn addresses the recurring posts on social media about nattokinase supplements as a "powerhouse" for reversing atherosclerosis. Is there new data? Is it powerful? Would mainstream medicine accept it? Should you use it? These questions and more are addressed.

Other topics include the risks of sleep apnea with insomnia, sleep duration and glucose control, possible risks of spermidine, and the happy feeling that eating flavanol-rich foods like grapes can give you.
