A recent Instagram promotion by popular actor Samantha Ruth Prabhu has ignited a firestorm. She endorsed a supplement brand, claiming its NMN (Nicotinamide Mononucleotide) content boosts NAD+ (Nicotinamide adenine dinucleotide) levels, leading to enhanced energy and focus. However, this endorsement quickly drew sharp criticism from Dr. Cyriac Abby Philips, famously known as The Liver Doc, who didn`t mince words, labelling the actress a ‘science illiterate movie celebrity’ and the company a ‘fraud’.
The Liver Doc swiftly countered Samantha`s claims. Sharing a screenshot of her post, he wrote, “How science illiterate movie celebrities defraud their millions of followers by selling supplements that do not work at all.” He urged the public to “Beware of snake oil salesmen, or snake oil saleswomen. They come in various sizes and forms. Be a well-informed consumer. Progress with science and evidence. Listen to real doctors.”
Dr. Philips explained that while NAD is a vital coenzyme for metabolism, NMN supplements are "claimed" to replenish it without solid proof. He stated, “There is zero proof that it is absorbed properly and reaches organs as claimed. NMN, by default, cannot enter cells.” He further elaborated, “In practical terms, most NMN taken by mouth is first converted to plain nicotinamide before anything useful can happen. Whatever bump in blood NAD+ you get is small and fleeting, and we have zero evidence that the molecule reaches key tissues at effective concentrations in people.” Supporting his stance with various studies, he dismissed human trials on NMN as ‘short, small, and stuffed with useless indirect endpoints and nothing of clinical significance’.

This isn`t Samantha`s first brush with criticism over health endorsements. She previously faced backlash for recommending hydrogen peroxide nebulisation and discussing liver detox with dandelion on her podcast, both flagged by medical experts as unscientific.
