For any product to gain acceptance by consumers, its quality and nutritional content must be consistent from the time of processing, through distribution and storage to the final consumption of the products. The Food and Drugs Administration (FDA) regulates the nutraceutical products with respect to nutritional and potency values placed on label: these values can decrease over time due to deteriorative chemical reactions. For this, GLC products adhere to stability protocols. Since nutrient potency declines over time, we have determined the proper overages necessary to ensure each product maintains 100% of its potency throughout its shelf life. Every capsule, powder, liquid, and bar is as potent from the day you purchased it to the day of its expiration date.
