NABL vs Informed Sport Certification: What's the Real Difference?

If you're buying protein supplements in India, you've probably noticed two different testing claims popping up on labels and websites: NABL-accredited laboratory testing and Informed Sport certification.

Both involve lab testing, but they're fundamentally different things.

NABL accredits laboratories for specific testing activities. Informed Sport is a certification programme for sports supplements, focused on reducing the risk of prohibited-substance contamination.

For the average buyer, this distinction might not seem like a big deal. For competitive and drug-tested athletes, it can make all the difference.

NABL vs Informed Sport: quick comparison

The key thing to understand is that NABL and Informed Sport aren't competing certifications. They provide different kinds of assurance for different purposes.

What is NABL accreditation?

NABL stands for the National Accreditation Board for Testing and Calibration Laboratories. It is an Indian accreditation body which assesses the technical competence of a testing and calibration laboratory to perform a specific task. NABL accreditation of testing laboratories is based on ISO/IEC 17025, which specifies the requirements for laboratory competence, impartiality and consistent testing.

Here's what you really need to understand: NABL accreditation is scope-specific. A lab might be NABL accredited for certain tests but not for everything it does.

So when a protein brand claims "tested at a NABL-accredited laboratory", don't stop there. Ask yourself:

• Which lab actually did the testing?
• What exactly was tested?
• Was that specific test within the lab's NABL-accredited scope?
• Which batch was tested?
• What were the actual results?

What NABL actually tells you: NABL gives you information about a laboratory's competence for specific accredited tests. What it doesn't do is automatically certify that a protein supplement is safe for drug-tested athletes.

What is Informed Sport certification?

Informed Sport is a testing and certification programme built specifically for sports nutrition products. Its entire focus is on the risk of prohibited-substance contamination in supplements that athletes use.

The programme tests products for a broad range of banned substances, with every batch of certified products screened before it hits the market. The testing itself is done through ISO/IEC 17025-accredited laboratories.

Instead of asking "is this laboratory technically competent to run this test?", Informed Sport is built around a different question: "has this specific supplement gone through a sports-focused certification process checking for prohibited substances?"

NABL vs Informed Sport: how the testing actually differs

NABL evaluates the laboratory and its competence for certain tests. The accredited scope tells you which tests and methods the lab is approved to perform. A lab might be NABL accredited for nutritional analysis, chemical testing, or microbiological testing — you need to check the specific scope.

Informed Sport evaluates specific supplement products under its certification programme. The testing is geared toward substances banned in sport and the risk of contamination in sports supplements. Informed Sport also has a searchable database where you can look up certified products and, in some cases, batch information.

Is NABL accreditation enough for a drug-tested athlete?

A NABL-accredited lab report can provide solid testing evidence, but the statement "tested by a NABL-accredited laboratory" doesn't automatically mean a product is certified for drug-tested athletes. You need to dig deeper:

• What substances were actually tested?
• Did the testing include prohibited-substance screening?
• Was that test within the lab's accredited scope?
• Which batch was tested?
• What were the results?

A lab can be highly competent while still not running the specific tests that matter to an athlete concerned about banned substances. For athletes subject to anti-doping rules, sports-specific certification provides far more relevant information than a general lab accreditation statement.

What about international recognition?

NABL is an Indian body, but its accreditation carries international relevance through mutual recognition agreements with international and regional accreditation organisations.

However, NABL's role remains laboratory accreditation. Informed Sport has a different kind of recognition because it works specifically within the sports supplement industry and is built around the needs of athletes and sports organisations.

Which one should you look for?

For general product testing, a report from a NABL-accredited laboratory is useful when the lab is clearly identified, the relevant test is within its accredited scope, the batch tested is clearly identified, and actual results are available.

For competitive or drug-tested athletes, Informed Sport certification is more directly relevant because it's specifically designed around prohibited-substance contamination in sports supplements.

If you're a serious athlete, don't stop at "lab tested". Find out:

• What was actually tested?
• Who performed the testing?
• Was the test within the lab's accredited scope?
• Were prohibited substances specifically screened for?
• Can the product or batch be verified through the certification programme?

How Indian buyers can verify these claims

If the product claims NABL-accredited testing:

• Find the testing laboratory's name.
• Look it up through NABL's official system.
• Check its current accreditation status.
• Review its accredited scope.
• Confirm the relevant test is actually covered.
• Check the batch number and actual test results.

If the product claims Informed Sport certification:

• Search the product in the official Informed Sport database.
• Confirm the product name and variant.
• Check the certification status.
• Where available, verify the batch or lot number.
• Ensure the information matches the product you're buying.

Don't judge a supplement by how many logos it displays. Look at what each credential actually verifies.

The bottom line

NABL and Informed Sport serve two very different purposes. NABL accreditation assures you that a laboratory is technically competent to perform specific tests within its accredited scope. Informed Sport certification is specifically focused on sports supplements and the risk of prohibited-substance contamination.

For a general protein buyer, NABL-accredited lab testing can provide useful technical evidence — as long as you understand what was actually tested. For a competitive or drug-tested athlete, a sports-specific programme like Informed Sport is more directly relevant to the risk you're managing.

FAQs

Is NABL the same as Informed Sport? No. NABL accredits labs for specific tests. Informed Sport is a sports supplement programme that tests for banned-substance contamination.

Is NABL testing enough for drug-tested athletes? Not by itself. NABL shows the lab is competent for certain tests, but it doesn't confirm the product went through sports-specific banned-substance screening.

Is Informed Sport better than NABL? Different tools, not competitors. NABL is about lab competence. Informed Sport is specifically about supplement contamination risk in sport. For athletes, that sports focus usually matters more.

How do I check a NABL claim? Find the lab's name, search NABL's directory for its accreditation, and check that the exact test in the report is actually inside its accredited scope.

How can athletes verify Informed Sport? Search the official Informed Sport database for the product, confirm the certification status, and match the batch or lot to what you're buying.
