Bulk Nutrients' Protein Lab Test Results

Want to know what’s really in your protein powder? You’re in the right place.

Every month, we publish our latest independent NMI lab test results, so you can see how our proteins stack up in the real world.

Over the past 13+ years, we’ve completed and published more than 700 independent protein lab tests across our range. It’s all part of our long-term commitment to transparency, consistency, and quality. It’s not something we do from time to time - it’s something we’ve built into the way we operate.

Why We Publish Our Protein Test Results

Like most brands, our packaging lists a best-case figure for protein content. The difference is that we also publish the actual lab results, so you can see how closely those figures hold up in practice.

It’s a simple idea: show the numbers, stay consistent, and let the results speak for themselves.

Understanding Natural Variation in Protein Testing

From time to time, you might notice a result that sits up to 3% outside our stated specification. This is within our accepted tolerance and is usually due to natural seasonal variation in milk, not any change in formulation or product quality.

In other words, the raw ingredients can shift slightly, but our commitment to accuracy and transparency doesn’t.
