Everyone should take a multivitamin. It's a simple, effective way to support long-term cognitive health, especially for middle-aged and older adults. About a decade ago, multivitamins were deemed useless or harmful. Recent large, randomized controlled studies provide irrefutable evidence to the contrary. Adults taking a standard multivitamin for 2 years improved cognition and episodic memory, equivalent to a 2-year reduction in cognitive aging. Multivitamins provide micronutrients missing from our diets—those important for metabolism, neurotransmission, and most importantly, reducing DNA damage and oxidative stress that contribute to aging. Think of it as nutritional insurance for your body and brain. And don't let anyone tell you it's just making "expensive urine."
