The shelf life of Herbalife products can vary depending on the specific item and its formulation. Generally, most powder products, such as protein shakes and nutritional supplements, have a shelf life of approximately two years from the date of production. Liquid products, on the other hand, may have a shorter shelf life and typically last around one year. It is always essential to check the product packaging for a "best by" or expiration date, as this will provide the most accurate information regarding the product's freshness. Proper storage conditions can also help maintain the quality of the products for a longer period. For more specific inquiries about a particular product's shelf life, one may want to refer to the official Herbalife website or contact a knowledgeable representative for detailed information.
