Bulk Nutrients Lab Testing Policy

At Bulk Nutrients, we take our products’ purity very seriously.

To maintain our supplements’ consistently high quality, we send a cross section of our product range to the National Measurement Institute (NMI) which is an independent lab run by the Australian Government.  This is the same organisation that does police forensic testing, ASADA drug screening and accuracy tests for multinational food manufacturers.

What does it mean for you?

Bulk Nutrients is founded on a principle of delivering Australia’s purest supplements at the most affordable prices.  But this doesn’t mean we need to sacrifice quality.

Regular product testing ensures that you’re receiving the most bang for your buck, with no fillers or nasties included.  When you buy a Bulk Nutrients product, you’re getting exactly what’s listed in the ingredients.

The idea of regular product testing sounds simple, but we’re constantly amazed that more supplement companies (Australian and international) don’t back up their claims with factual proof of what’s in the bag.

Our advice, ask your current protein supplier for test results that back up their claims.  If they can’t provide these results, it might be time to shop elsewhere.

Bulk Nutrients’ latest lab test results

Each month we update this page with our latest results, so you can transparently see how pure our proteins are.

Occasionally you may see our proteins out of specification by about 2% - this is due to seasonal variations in the natural whey protein.

On our packaging we join the other companies in the industry and state the best case scenario when detailing our nutritional information.

NMI’s testing process

Each month we take samples from random production runs, bag them and send them to The National Measurement Institute for testing.

The NMI uses a standard Kjeldahl Nitrogen test for protein testing and guarantee their accuracy.

We normally receive results from the NMI within 3-4 weeks and place the results of these tests in the latest results section of this page.

How to get a sample tested

As our own research indicated many companies were severely under dosing their proteins so we decided to offer a service where consumers could send a sample of any protein they have purchased directly to NMI lab testing for verification.

This has helped hundreds of people to know whether they have been buying accurately labelled protein, a service that no other company has ever offered.

If you would like your protein lab tested, you will need to do the following.

  • Contact us at proteintest@bulknutrients.com.au
  • Ensure the protein you want tested was purchased by yourself.
  • Guarantee you have been the only one to use the protein purchased
  • Take photographs of all packaging and batch identification data for records.
  • Isolate at least a 30g sample of the protein you want tested and identify it.
  • Fill in and sign a declaration (which we will provide) which includes when and where your protein was purchased, and a guarantee has not been tampered with in any way.
  • Fill in some basic paperwork that matches your protein.
  • Send the sample of protein with your paperwork to NMI laboratories directly.
