As the category of sports nutrition matures, so does the science behind it, and few ingredients illustrate that shift better than creatine. Once viewed as a niche performance supplement, creatine has entered the mainstream, driven by a growing body of research, broader consumer education, and innovation in product formats.
While advanced technology often takes center stage in discussions about scientific accuracy, the age and preparation of samples are equally critical. By prioritizing the seemingly small details, researchers can ensure that their findings stand up to scrutiny and contribute meaningfully to scientific progress.
In the dietary supplement and ingredient industry, protecting consumer health and meeting regulatory expectations are nonnegotiable. One critical aspect of quality control is residual solvent testing. Residual solvents, volatile chemicals used during manufacturing, can remain in products if not properly removed.
When evaluating fiber testing approaches, it’s important to review how results differ across sample matrices tested by both the new and previous methods. More laboratories are implementing the Rapid Integrated Dietary Fiber Methods - AOAC Official Methods 2017.16 and 2022.01. The AOAC 2017.16 method measures the insoluble fiber fraction (IDF) and soluble fiber fraction that precipitates in 78% ethanol (SDFP) together, and separately measures the soluble dietary fiber not precipitated in 78% ethanol (SDFS) by HPLC.
Postbiotics, defined as non-viable microbial cells, their components, or metabolites that confer health benefits to the host, represent a rapidly expanding frontier in microbiome research and functional ingredient development. Watch this webinar for a comprehensive look at the rapidly evolving field of postbiotics, combining cutting-edge science, global regulatory insights, and practical testing methodologies.
