Dr Sinclair said the technique could allow people to regenerate organs, and even allow paralysis sufferers to move again, with human trials due within two years.

Professor Sinclair said he hoped the pill would be available to the public within five years and cost the same each day as a cup of coffee.
'We do not recommend people go out and take NAD precursors as they have not yet formally tested for safety,' he said.
