Bryan Johnson's Anti-Aging Blood Transfusion: How Does it Work?

In pursuit of eternal youth and the desire to combat the effects of aging, various scientific and medical advancements have been explored. One such area of investigation is the potential role of blood transfusions in anti-aging therapy.

Key takeaways:

This article explores one of the prominent characters who uses blood transfusions — 45-year-old tech tycoon Bryan Johnson, who periodically does blood swapping with his son to prevent aging and stay young.

What is an anti-aging blood transfusion?

An anti-aging blood transfusion or young blood transfusion, is a controversial procedure in which blood from a young person is transfused into an older person with the goal of slowing down or reversing aging. The procedure is based on the idea that young blood contains substances that can help repair damage in older cells and slow down or reverse the aging process.

The medical community does not recognize or support any established medical procedure referred to as an 'anti-aging blood transfusion.' However, there has been speculation and interest in the potential use of blood transfusions for anti-aging purposes.

How does an anti-aging blood transfusion work?

The concept behind the anti-aging blood transfusion is based on the idea that young blood may contain components that can positively influence aging-related processes or reverse certain aspects of the aging process. The hypothesis is that introducing these factors into older individuals circulatory systems could potentially provide the following benefits:

  • Enhanced tissue repair
  • Improved organ function
  • Reduced age-related decline

It is important to note that research studies on anti-aging blood transfusions are still in very early stages, and the effects on humans are not yet fully understood. While some studies have shown promising results in animal models, the translation to human applications is complex and requires extensive research and clinical trials.

Bryan Johnson's anti-aging blood transfusion strategy

Bryan Johnson, a 45-year-old tech tycoon, has been undergoing regular blood transfusions for anti-aging for several years. He reportedly receives plasma from young donors, which is the liquid part of blood that contains proteins, nutrients, and hormones. The plasma is then infused into his bloodstream.

Bryan Johnson’s anti-aging blood transfusions, together with his other anti-aging therapies, cost him around $2M a year. Johnson has said that he believes the blood transfusions have helped him improve his cognitive function and physical health. Johnson has been swapping plasma from anonymous donors, but recently, he urged his son Talmage to be his 'blood boy,' and donate a liter of his blood instead. Three batches of blood were given: one of platelets, one of red and white blood cells, and one of plasma.

When Johnson began his effort to slow down the aging process, he started on a very strict regimen by waking up at 5 am and taking various pills and supplements. He also follows a low-calorie vegan diet and gets an hour of exercise every day.

Johnson claims that after performing numerous experiments on his body, he now has the skin and lung capacity of a 28-year-old. He has also said that he feels younger and more energetic since starting the treatment.

However, there is no strong scientific evidence to support Johnson's claims. In fact, the FDA has warned against the use of young donor plasma infusions for anti-aging purposes, stating that they are still an unproven treatment.

Potential anti-aging benefits of blood transfusions

Blood transfusions are routinely done during surgery and can be a life-saving treatment for many conditions. However, mounting research suggests that it can be a potential anti-aging strategy as demonstrated in animals and as applied by Bryan Johnson.

Donated blood is typically younger than the recipient's blood, and it may contain higher levels of certain proteins that have anti-aging properties.

Young blood transfusions may have potential longevity and anti-aging benefits, such as:

  • Improved cognitive function. Blood transfusions from young to old have been shown to improve cognitive function in mice. It may also slow Alzheimer's disease and increase the production of new neurons in the hippocampus, a part of the brain that is important for learning and memory.
  • Improved metabolism. Blood transfusions have also been shown to improve metabolism in mice. This may be due to the fact that young blood contains more antioxidants, which can help protect cells from damage.
  • Reduction of inflammation. Blood transfusions may help to reduce inflammation, which is a major factor in aging. Blood from young mice contains lower levels of inflammatory molecules than blood from old mice. This suggests that blood transfusions from young mice may help to reduce inflammation in old mice, which could have a number of health benefits.
  • Increased stem cell production. Blood transfusions may stimulate the production of stem cells, which are responsible for repairing and regenerating damaged tissues. Parabiosis experiments in mice also reported stem cell rejuvenation across aged tissues.
  • Enhanced immunity. Senescent T-cells can be rescued through the transfer of telomeres from another blood immune cell called antigen-presenting cells (APCs) and promote long-term immunological memory. Through young blood transfusion, this mechanism may promote immune enhancement.

However, while young blood transfusions are promising, the scientific evidence to support the anti-aging benefits is not yet fully established. A deeper investigation and large clinical trial are needed to determine conclusive evidence. Meanwhile, there are some potential risks associated with blood transfusions, such as the transmission of infections, the development of antibodies against the donated blood, allergic reactions, and transfusion reactions — hence, there are some roadblocks that need to be addressed as this strategy is still in its infancy.

Can blood transfusions cause problems later in life?

While blood transfusions can provide immediate benefits in certain medical situations, there are potential risks and complications associated with transfusions. However, the likelihood and severity of long-term problems resulting from blood transfusions are generally low, especially when transfusions are administered with appropriate screening, testing, and matching procedures.

Here are some possible complications and considerations related to blood transfusions:

  • Allergic reactions
  • Infection
  • Transfusion-association injuries
  • Graft-versus-host-disease (GvHD)

If you are considering having a blood transfusion, it is important to talk to your doctor about the risks and benefits. They can help you decide if a transfusion is the right treatment for you and minimize the risks.

Overall, young blood transfusions as a potential anti-aging therapeutic strategy is an intriguing concept that has emerged from preclinical studies on animal models.

While they may hold promise for the future, extensive research and clinical trials are needed to determine the true potential, safety, and effectiveness of young blood transfusions. As the scientific community continues to unravel the mysteries of aging, blood transfusions remain a topic of interest, offering a glimpse into the fascinating possibilities of rejuvenation and longevity.
