The Citizens Protein Project 2: the first publicly funded study of protein supplements in India
No regulator has acted on this finding. It comes from a published study or a private testing company, and the brand may dispute it.
Scope. A record here does not by itself mean a product or company is unsafe or banned today. Regulatory actions can apply to one batch, one formulation, one period or one state. Always check the linked government document for the current position, and tell us if something is out of date. How we label records.
Below: Blacklisted's explanationWe explain what the test or study found. No regulator has acted on it.

B-Protin was one of 34 products tested in the Citizens Protein Project 2, published in Medicine on 14 Nov 2025. The laboratory measured 10.12 g protein per 100 g and reported: heavy metals (cadmium 0.015); aflatoxin 11.18 µg/kg; progesterone 0.00291; undeclared sucrose 4.83 g/100 g; taurine 3.75 mg/100 g. The weakest medical product on protein and one of only three with aflatoxin, B-Protin was also the only product in the study to show cadmium, progesterone and undeclared sucrose together. It had failed on protein in the 2024 round as well.
Figures are from the project's results site; units for metals, hormones and aflatoxin are being checked against the paper. No FSSAI action on the product is on record.
What this means for you
Detected is not the same as over the limit
The study reports what the laboratory found. Aflatoxin figures are below FSSAI's limit of 20 µg/kg for foods not specified; heavy-metal and hormone figures are reported without a limit comparison.
Undeclared sugar and taurine are label questions
Sucrose or fructose not on the label, and taurine that can inflate protein readings, are the study's main concerns for medical powders.
This is a record of official orders, not medical advice. Do not stop a prescribed medicine without asking your doctor or pharmacist.
