Age reversal potential - reduce disease risk and slow premature aging

The 21st century could see anti-aging therapies that are as important to people as antibiotics were in the past century. How we think about aging might undergo a radical change. However, there may not be a "cure", but efforts to eliminate lethal disease. Prevent rather than react or treat.

Age reversal - reduce disease risk and slow premature aging

Age reversal research is rapidly accelerating. Life Extension's goal in studying emerging rejuvenation treatments is to validate what works, what fails, and what potencies are needed to provide real-world benefits. 

An example is senolytics, where the purpose is to remove senescent cells that otherwise inflict massive tissue damage. 

Life Extension is monitoring anti-aging research and interacting with the scientists to validate whether this telomere elongation is associated with indicators of systemic age reversal.  

The immediate goal is to develop and validate rejuvenation therapies to provide maturing adults with an additional 15-25 healthy years.

Prevent, delay and reduce rate of telomere shortening

Fight back against aging and help keep an essentially youthful you >>
Scientists have discovered that shorter telomeres lead to a higher mortality rate. Like the burning of a fuse, telomeres at the ends of our chromosomes steadily shorten every time a cell replicates itself. (1,2) 

While aging is a many-faceted process, a clear-cut biomarker for aging at the cellular level has been found in measurements of telomere length. Studies demonstrate that longer telomeres can be promoted by maintaining adequate intake of specific nutrients.

Shortening telomeres accelerate cellular aging, but nutrients that promote telomere repair and sustain telomere length have proven health benefits.

What can you do today to reduce your rate of telomere shortening?

Nutrients that prevent and delay telomere shortening 

In recent years, we have learned that even common vitamins can have dramatic impact on the lengths of the telomeres in our cells, thereby powerfully decelerating aging at the cell, tissue, organ, and whole organism levels. (3)

  • Walnuts contain healthy fats, fiber, vitamins, minerals, and many different compounds with proven health benefits. Harvard research published in the journal Nutrients in 2021 now links walnuts to greater life expectancy. (4)
  • B vitamins preserve telomere length in part by lowering homocysteine, which accelerates telomere shortening. (5-7)
  • Vitamin D promotes activity of telomerase, the repair enzyme that steadily adds to telomere length. (8-11)
  • Vitamins C and vitamin E preserve telomere length by reducing the chemical stresses that contribute to telomere shortening. Gamma-tocotrienol in particular may reverse telomere shortening and attendant cellular aging. (12-16)
  • The vegetable carotenoids, such as lutein, contribute to longer telomeres, though mechanisms for these effects remain to be discovered. (17,18)
  • Studies indicate that ergothioneine, found in mushrooms, can delay telomere shortening due to oxidative stress. (19) Your telomeres are like protective caps at the end of your chromosomes. As time goes by, these telomeres shorten naturally, in step with your aging process.
