Synthetic Versus Natural Caffeine And How Each May Affect Aging

Caffeine is consumed by 75% of Americans, primarily from lab-synthesized sources like Pepsi and Red Bull. Emerging research suggests that synthetic caffeine may accelerate aging, while naturally occurring caffeine in coffee and tea could have anti-aging effects. Studies have linked higher caffeine intake from synthetic sources to shorter telomeres, markers of cellular aging. Conversely, increased coffee consumption has been associated with longer telomeres. Antioxidants in coffee and tea may contribute to their anti-aging effects, protecting DNA and reducing oxidative damage. Green tea has also shown protective effects, while synthetic caffeine has been linked to DNA damage. The FDA recommends limiting caffeine intake to 400 milligrams daily, but energy drinks can contain excessive amounts of synthetic caffeine. While coffee and tea may have cardioprotective benefits, experts advise caution and recommend taking breaks from caffeine to avoid dependence.
