So, what is l-cystine?

L-cystine is a non-essential amino acid that is naturally found in many high-protein foods, such as eggs, dairy products, and meat. It is a crystalline substance that is soluble in water and has a slightly sweet taste. L-cystine plays an important role in the body's natural antioxidant defense system, as well as in the maintenance of healthy skin, hair, and nails. It is also commonly used as a food additive to enhance the flavor and texture of baked goods and snacks. L-cystine is safe for consumption and has no known side effects when taken in recommended doses.
