Scientists discover molecule that acts like exercise and slows signs of ageing | Health
We all know exercise is great for staying healthy, but scientists have long been trying to understand why it works so well—especially at the deepest, molecular level. Now, a new long-term study may have found a big piece of the puzzle: a tiny molecule called betaine.
A Natural Molecule With Big Benefits
Betaine is found naturally in foods like spinach and sugar beets. It has been linked to good health before, but this is the first time researchers have connected it directly to the benefits of exercise—especially its powerful anti-aging effects.
Scientists from Xuanwu Hospital at Capital Medical University in China followed 13 healthy men who took part in regular running. Using an advanced “multi-omics” approach, the team tracked changes in genes, proteins, immune responses, and small molecules inside the body.
Regular Exercise Boosts Betaine Levels
Here’s the interesting part: the participants’ kidneys began producing much higher levels of betaine over time.
A single 5 km run caused short-term stress, but a month of consistent running led to:
- Slower cellular aging
- Less cellular damage
- A healthier gut microbiome
- A stronger immune system
Researchers then tested betaine in mice and discovered it blocks an enzyme called TBK1, which is linked to inflammation and aging. This means betaine isn’t just a byproduct of exercise—it’s actively driving some of exercise’s most powerful anti-aging benefits.
As biophysicist Liu Guang-Hui from the Chinese Academy of Sciences explains:
“This study gives us a fresh way to turn how our body works into something we can target with chemicals. It opens the door to treatments that support healthier aging.”
Could We One Day Take “Exercise in a Pill”?
The researchers are careful to clarify that pills won’t replace the gym anytime soon. Physical activity offers many benefits—like stronger muscles, improved mood, and better heart health—that no supplement can fully mimic.
However, understanding betaine’s role could help scientists create new treatments for people who:
- Are aging
- Cannot exercise regularly
- Are at risk for age-related diseases
These treatments could support healthier aging and improved organ function.
A Promising First Step
The study is small and needs to be repeated in larger groups over longer periods. But identifying betaine as a key anti-aging molecule is an exciting breakthrough.
As the researchers write, this discovery “redefines exercise as medicine.”
The study was published in the journal Cell.
