What if your brain fog, poor sleep, anxiety, or memory struggles aren't caused by aging—but by a mineral deficiency that most doctors never test for? In this episode of Alzheimer's Breakthrough, Dr. Josh Helman explores the critical role magnesium plays in brain health, memory formation, sleep quality, stress resilience, and cognitive aging. You'll learn why nearly half of Americans may not be getting enough magnesium, why standard blood tests often miss deficiencies, and why the form of magnesium you take could make all the difference. Dr. Josh breaks down the science behind magnesium L-threonate, the only form of magnesium shown in clinical research to effectively cross the blood-brain barrier and increase magnesium levels in the brain. He also reviews the latest research on sleep, memory, cognitive performance, and healthy brain aging.
