Many people are searching for a magic pill to stop aging, but experts emphasize that the foundation of longevity is cellular health.

The New York Post shares which three supplements may slow down aging.

What you need to know about supplements

According to nutrition biochemist Erin Barrett, the condition of your cells determines how your body ages. When cells gradually lose their ability to function properly, the risk of chronic diseases and age-related changes increases.

Experts identify three key supplements that can support the body during the aging process.

Antioxidants — protect cells from aging

Antioxidants help fight oxidative stress and inflammation — processes that accelerate cellular aging.

They can be obtained from colorful fruits and vegetables, as well as foods rich in vitamins A and C. Muscadine grapes are especially beneficial, as they contain high levels of polyphenols.

Research shows that these compounds may improve skin elasticity and help the body combat inflammatory processes.

Protein — supports muscles after 40

Protein plays a crucial role in tissue repair, immune support, and muscle development.

After age 40, the body becomes less efficient at using protein for tissue repair, which gradually leads to muscle loss. This process is called sarcopenia and can result in weakness and loss of physical independence.

Experts recommend consuming about 1–1.2 grams of protein per kilogram of body weight per day, evenly distributed across meals.

Creatine — energy for muscles and brain

Another promising supplement is creatine.

This amino acid naturally occurs in muscles and helps the body rapidly produce energy. Research shows that creatine can:

  • Improve physical endurance

  • Support muscle recovery

  • Boost brain function

  • Enhance cognitive test results in older adults

The brain uses about 20% of the body’s total energy, so a stable energy supply is critically important for its function.

Can supplements extend life?

Experts stress that no supplement is miraculous. They work best in combination with a balanced diet, physical activity, and a healthy lifestyle.
