What is a proprietary blend?

A proprietary blend is a combination of ingredients or substances in a product that is protected by a trade secret or trademark. Proprietary blends can be found in various types of products, including supplements, food items, and cosmetics, among others. The combination of ingredients is unique to the product and the manufacturer may not disclose exactly how much of each ingredient is used or the precise formula for creating the blend. The purpose of a proprietary blend is to give a manufacturer a competitive edge in the market and prevent others from replicating their exact product. However, some critics argue that proprietary blends can make it difficult for consumers to make informed choices about the products they are consuming.
