If You Have This Blood Type, You May Age More Slowly

A recent study published in the journal Experimental Gerontology, suggests that your blood type could influence how quickly you age — and people with blood type B might have a major advantage.

The Study Behind the Claim

Published in Experimental Gerontology, the 2024 study analyzed the biological age of 11 organs in over 5,000 volunteers and tracked more than 4,000 proteins in their blood.

Blood Type B Linked to Slower Aging

Researchers found that around 20% of people show signs of accelerated aging in at least one organ —
but this was not observed in individuals with blood type B.

A Theory Dating Back 20 Years

Interest in the connection between blood types and aging isn’t new. In 2004, scientists studied centenarians in Tokyo and found that blood type B was overrepresented among those 100 and older.

Why Might Blood Type B Age Better?

People with blood type B have the B antigen on their red blood cells and produce antibodies against A antigens, which could contribute to a stronger regenerative system.

Better Stress Management?

Some researchers believe that people with blood type B may have a more efficient cellular repair system, while others suggest they manage metabolic stress better.

What About Other Blood Types?

A separate study published in Neurology in 2022 revealed that people with blood type A have a higher risk of stroke before age 60 compared to those with blood type O.

Still No Definitive Answers

Although this new research is promising, scientists caution that it’s still too early to say whether blood type alone determines aging speed.

A Path Toward Better Health Insights

These findings open the door to further research into personalized medicine, helping us understand how our genetic and biological makeup influences aging.

What’s Your Blood Type?

It might not be the only factor in how you age — but if you’re type B, science says you may have a head start in staying younger, longer.
