Doctors Warn: Popular Brain Boosters May Harm

Americans are spending over $3.56 billion yearly on supplements promising enhanced focus and memory, but experts caution some of these 'brain boosters' may have adverse effects, potentially increasing brain age. Three physicians have identified six supplements or combinations that could put users' mental capacity at risk.

Among the flagged supplements are vitamin E, ashwagandha, and turmeric, which, despite claims of neuronal protection or inflammation reduction, may contribute to brain bleeds or the buildup of damaging waste products in the blood. Combinations like fish oil with ginkgo and garlic, and even daily coffee with certain stimulants, are also warned against due to risks of bleeding or increased anxiety.

Doctors stress that maintaining a healthy lifestyle—including a good diet, regular exercise, social interaction, adequate sleep, and cognitive challenges—is paramount for brain health. Supplements should only be considered after a blood test reveals a deficiency, and indiscriminate supplementation, especially at high doses or in unbalanced combinations, is discouraged due to potential harms over benefits.
