Naturaltein was one of 34 products tested in the Citizens Protein Project 2, published in Medicine on 14 Nov 2025. The laboratory measured 80.16 g protein per 100 g and reported: progesterone 0.00362. Naturaltein was clean on metals, aflatoxin and sugar and strong on protein; its single flag is progesterone at about 0.0036 mg/kg (units:, being verified, one of three products with the hormone detected.

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 and units are being verified.

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.
