Doctors question the science behind Yuvraj Singh’s new supplement brand
Former cricketer Yuvraj Singh has launched Protocol32, a sports nutrition and wellness supplement brand.
Its product combines 32 FSSAI-approved supplements in one sachet, which Singh says is intended to support 13 pathways in the body.
Singh drew on his experience playing in the 2011 Cricket World Cup while living with cancer to explain why he takes health seriously.
Medical professionals have challenged the product’s science and safety, though the information provided does not detail their specific safety concerns.
Hepatologist Cyriac Abby Philips called the venture “the business of bad science” and said Singh could instead use his influence to promote evidence-based care.
The product was co-formulated with doctors Anurag Agrawal and Arpit Bansal, and others were involved in its development.
Protocol32 is invite-only, with the first batch limited to a few hundred people; no wider launch plans are given.
