In skincare products, it is incorporated for its antioxidant and anti-aging effects, helping to reduce oxidative stress and improve skin texture. Furthermore, NAM is used in animal feed as a dietary supplement to enhance growth and overall health in livestock. Its role in promoting protein synthesis and supporting metabolic functions makes it a versatile compound in various applications.
