It is commonly found in products like chocolate, margarine, and salad dressings to improve texture and consistency. In baking, it enhances dough stability and shelf life. In the pharmaceutical and cosmetic industries, lecithin acts as a stabilizer and moisturizer, often included in skincare products, lotions, and creams for its hydrating properties. It also aids in the delivery of active ingredients in medications. Additionally, lecithin is used as a dietary supplement to support brain health, liver function, and cholesterol management. Its versatility makes it a valuable component in various applications across multiple industries.
