What Are FSSAI Lab Test Protein Supplements?
FSSAI (Food Safety and Standards Authority of India) is the regulatory authority responsible for ensuring that food and nutritional products sold in India—including supplements—meet safety, hygiene and purity standards.
An FSSAI-certified lab test for protein supplements involves checking:
- Actual protein content
- Amino acid profile
- Presence of adulteration
- Carbohydrate and fat accuracy
- Microbial safety
- Heavy metals such as lead, arsenic, mercury and cadmium
- Authenticity of ingredients
- Label claim verification
These tests ensure that the supplement is safe, accurately labeled and free from harmful contaminants.

Why FSSAI Lab Testing Matters for Protein Supplements
Many supplements in the market make bold claims but fail to meet them. FSSAI testing is crucial because it helps detect:
- Fake and counterfeit supplements
- Under-dosed protein
- Amino spiking
- Harmful bacteria
- Excess heavy metals
- Mislabeled nutritional information
Choosing an FSSAI-tested supplement protects you from low-quality or unsafe products and ensures you get the results you expect from your fitness journey.
How FSSAI Lab Testing Works for Protein Supplements
Protein supplements are tested in FSSAI-approved or NABL-accredited laboratories using advanced scientific processes:
1. Nutritional Composition Test
Verifies whether the protein, carbs and fat match the label.
2. Protein Content Analysis (Kjeldahl or Dumas Method)
Accurately measures total protein in the supplement.
3. Amino Acid Profile Analysis (HPLC)
Detects amino spiking and ensures proper amino distribution.
4. Heavy Metal Test (ICP-MS)
Checks for lead, arsenic, cadmium and mercury.
5. Microbial Safety Check
Ensures the supplement is free from E.coli, Salmonella, yeast and fungi.
6. Stability and Shelf-Life Testing
Determines whether the supplement remains safe and effective until expiry.
After completion, a Certificate of Analysis (COA) is issued with accurate values.
How to Identify Genuine FSSAI Lab Tested Protein Supplements
Here are the signs that the protein supplement you’re using is genuinely safe and lab tested:
- The brand shares FSSAI or third-party COA reports
- Genuine FSSAI license number printed on the label
- QR code for verification
- Transparent ingredient list
- No unrealistic “30g protein per scoop” type claims
- Clean manufacturing details
- Proper batch number, MRP, manufacturing date and expiry
- No artificial boosting agents like glycine or taurine
If a brand hides its lab reports or does not show its FSSAI license, it is a major red flag.
