Ashwagandha is an adaptogen that reduces stress by lowering cortisol levels and balancing the hypothalamic–pituitary–adrenal (HPA) axis.
What role does ashwagandha play in improving deep sleep through stress and cortisol regulation?
Supplement quality verification involves much more than checking a product label or reviewing a Certificate of Analysis (COA). Different analytical testing methods are used to evaluate ingredient identity, purity, contamination, and consistency between production batches.
Techniques such as High-Performance Liquid Chromatography (HPLC), Liquid Chromatography–Mass Spectrometry (LC-MS), and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) can provide different types of information about tested materials.
However, every analytical method has limitations, and a single laboratory result does not necessarily establish the overall quality or safety of a finished product.
How do these advanced testing technologies work together to identify potential contaminants, verify ingredient identity, and improve transparency in the supplement industry? What should consumers and quality-control professionals understand when evaluating laboratory reports?
