Coffee is an underrated longevity hack. Here's how to use it to optimize your health.

Forget experimental peptides or expensive pills — the best longevity supplement is probably already in your pantry.

Coffee is one of the most-studied performance enhancers on the planet. Extensive research supports a laundry list of perks, from a short-term boost in strength, endurance, and focus to long-term protection against inflammation and serious illnesses.

In 2026 alone, studies linked coffee to benefits such as improved gut health, better mood, sharper cognition, healthy aging, and lower risk of liver disease.

The daily brew enjoyed by 66% of American adults packs a complex blend of antiaging and disease-fighting compounds to help us live longer and better. Beyond helping to prevent major causes of death like heart disease, cancer, diabetes, and dementia, coffee is also the most reliable way to get an edge in daily performance, whether you're an athlete or a CEO.

"Caffeine is one of the most powerful and one of the most consistent tools that we have for performance," sports nutritionist Tom Coughlin told Business Insider.

However, not all coffee is the same when it comes to health benefits. Researchers say that certain types of coffee may be healthier than others, and too much can backfire.

Business Insider spoke with experts about the multiple ways coffee affects your brain and body. They explained how to drink coffee for the greatest benefits and fewest side effects.

Neuroscientist Agenor Limon loves to start the day with a cup of coffee. The daily ritual — grinding beans, heating water, and brewing — stimulates a full sensory experience leading up to that first sip.

"Coffee helps feed the brain with the aroma, the taste, and the moment," Limon, a professor of neurology at the University of Texas Medical Branch, told Business Insider.

As the molecules in coffee hit your system, they interact with important receptors in the brain associated with alertness, attention, and memory, according to Limon. It also affects the vascular system, supporting healthy blood flow in the brain and body.

New research suggests those benefits persist beyond the initial feel-good rush. A study published in JAMA in February found that people who drank two to three cups of coffee daily had a significantly lower risk of dementia.
