A vitamin that could reverse the ageing process and make space travel possible will be trialled on humans this year and could be on the market in 2020.

Australian scientists have found a vitamin, nicotinamide mononucleotide (NMN), that helps cells repair DNA damage and it’s so good they are taking the pill themselves.

Middle aged mice given the vitamin lived 20 per cent longer and were able to run faster.

“The cells of the old mice were indistinguishable from the young mice, after just one week of treatment,” said This email address is being protected from spambots. You need JavaScript enabled to view it. of UNSW School of Medical Sciences and Harvard Medical School Boston.

“This is the closest we are to a safe and effective anti-ageing drug that’s perhaps only three to five years away from being on the market if the trials go well.”

In a paper published in Science today, the researchers identify a critical step in the molecular process that allows cells to repair damaged DNA.
