We've introduced a new test method for the determination of creatine, to support manufacturers of supplements and nutritional food products in ensuring product integrity and regulatory compliance.
The method using liquid chromatography tandem mass spectrometry (LC-MS/MS) offers high specificity, sensitivity, and selectivity, providing accurate results in complex matrices such as powders, capsules, tablets, and formulated products.
The new test gives manufacturers a high degree of confidence in the accuracy of their label claims, reinforcing transparency and helping to build consumer trust.
