Independent laboratory finding
B-Protin: Citizens Protein Project 1 finding (2024)
Last checked 1 October 2026
The Citizens Protein Project 1 (April 2024) found B-Protin contained about 10% protein against a labelled 40%, with trace aflatoxin; no FSSAI action on the product is on record as of 1 Oct 2026.

70% of 36 popular protein supplements sold in India mislabeled, 14 contain toxins, says new study
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 Always check the linked government document for the current position, and tell us if something is out of date.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.
Key facts
- Brand
- British Biologicals
- Study
- Citizens Protein Project 1 to 36 products, published April 2024
- Protein claimed
- 40%
- Protein found
- 10%
- Aflatoxin
- Trace (figure as reported in the paper)
- Also tested in CPP2 (2025)
- 10.1 g/100 g protein; aflatoxin 11.18 µg/kg; progesterone; cadmium; undeclared sucrose
- Regulator action
- None on record
B-Protin, a medical-nutrition powder from British Biologicals, was among the weakest performers in the Citizens Protein Project 1. The study reported about 10% protein by weight against a label claim of 40%, one of the largest shortfalls of the 36 products tested, and detected aflatoxin at trace level. The product was tested again in the project's second round in November 2025, which measured 10.1 g protein per 100 g and reported aflatoxin, progesterone, cadmium and undeclared sucrose; that result has its own page. No FSSAI action on B-Protin is on record, and no company response to either study has been located.
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.
