The supplement brands doing the best on the market provide consumers credible proof that the supplement is what it says it is. Consumers want to know the supplement is made with the highest quality ingredients, following current good manufacturing practices (GMP) as outlined by the US Food and Drug Administration (FDA).
Heavy metal analytical testing is a must to meet regulations and inform consumers. Inductively Coupled Plasma with Mass Spectrometry (ICP-MS) testing quantifies heavy metal content in ranges as low as parts per trillion. ICP-MS testing is the most accurate and cost-effective method to determine if a product requires Prop 65 mandated warnings.
Brand owners and contract manufacturers go to great lengths to produce a finished product that meets consumer needs. That same product can then remain on a shelf for a long time. Determining if the product will degrade, and consequently decrease in quality, benefits the consumer and the brand owner. Conducting a Stability Test on your product enables you to establish a “best by”, “use before”, or expiration date. After that date, the quality of the product is no longer guaranteed.
UV-Vis spectroscopy is a valid stand-alone means to determine and quantify nutrients and other components. In some instances, USP standards specify UV-Vis testing. Further interferences are decreased to improve detection levels when a UV-Vis detector is used with high-performance liquid chromatography (HPLC) testing.
There is nothing more expensive for a company than a recall. Public safety issues cause recalls. When recalls happen, the brand owner eats every cost associated with producing and distributing their product. For food, dietary supplements, and cosmetics, recalls occur when the product contains harmful microorganisms or heavy metals.
