Harvard Professor David Sinclair and researchers from the University of New South Wales developed the new process, which involves reprogramming cells.
The science behind the new technique involves the molecule nicotinamide adenine dinucleotide (NAD), which plays a key role in generating energy in the human body.
Professor Sinclair, who is using the NMN molecule to reduce the aging process, said his biological age has dropped by 24 years after taking the pill.
