Expert predicts first anti-aging pills available in 2028.

Pills that can help reverse the effects of aging could be on the market within five years, according to Andrew Steele, author of 'Ageless: The new science of getting older without getting old'. Steele points to existing medications, such as the diabetes tablet metformin, that could be retooled as anti-aging treatments in the 'very, very near term'. Steele believes that treatments we are likely to see in the near term will extend 'healthspan' by dealing with age-related diseases, delaying the onset of problems such as dementia.
