Frotein Whey, marketed by BigMuscles Nutrition as a whey protein concentrate, was reported by the Citizens Protein Project 1 to contain 26.1% protein by weight against a label claim of 76.5%, a shortfall of two-thirds. The study, a self-funded effort by clinicians and citizens published in Medicine in April 2024, tested a single retail sample of each product at an accredited laboratory. BigMuscles rejected the result, stating publicly that the report was forged. FSSAI has taken no action on the product. The brand also appears on Trustified's FAIL list and in Unbox Health's lowest whey grade for other products.
What this means for you
A study result, not a regulatory finding
FSSAI has taken no action on this product on the basis of the study. The finding describes the sample the researchers bought.
If you use it, ask for the batch certificate
Manufacturers hold certificates of analysis per batch. NABL-accredited laboratories will also test a tub for protein and contaminants.
This is a record of official orders, not medical advice. Do not stop a prescribed medicine without asking your doctor or pharmacist.
