Everyday we grow older and add years to our lives. Our body also ages. It becomes weaker and more prone to injuries and diseases. That's a fact of life. In a new study, scientists say that the drug cocktail they formulated was able to reverse patients' biological age.
While we tend to define age as the number of years we have been alive – our "chronological age", so to speak – there is another definition, which relates to how fast our body is aging and when we can expect to see symptoms and disease associated with old age: it is our "biological age".
Nine patients were put on a regimen that required they take one growth hormone and two diabetes drugs (dehydroepiandrosterone, or DHEA, and metformin). Researchers used four epigenetic clocks to determine the volunteers' biological age and, to their surprise, found the drug cocktail reversed biological aging by an average of 2.5 years.
