Taking daily multivitamins appears to slow cognitive aging by about 2 years in older adults, three new studies show.

In the latest study, published Thursday in The American Journal of Clinical Nutrition, researchers observed and tested 573 adults 60 and older in person. In the two previous studies, people taking part in the research responded by phone or online. Overall, about 5,000 people took part in the three studies.

The in-person study showed the multivitamin provided a “modest benefit” on global cognition over 2 years, compared to a placebo. Global cognition includes brain activities such as reasoning, attention, and planning. The multivitamin showed “a statistically significant benefit” for episodic memory, but not in executive function and attention, a news release said.
