  1. What is L-carnosine and what does it do in the body?
    L-carnosine is a naturally occurring compound made from the amino acids beta-alanine and histidine. It is found in high concentrations in muscle and brain tissue, where it provides antioxidant support and helps protect proteins and cells from oxidative stress. L-carnosine also supports healthy muscle function and overall cellular health.
  2. Why is L-carnosine popular with athletes?
    L-carnosine is naturally concentrated in skeletal muscle, where it helps support normal muscle function during exercise. Its antioxidant properties and role in maintaining healthy muscle tissue have made it a popular supplement among active individuals and athletes.
  3. What is glycation, and how does L-carnosine help?
    Glycation is a natural process in which sugars bind to proteins, fats, or DNA, forming compounds called advanced glycation end products (AGEs). Over time, AGEs can affect the normal structure and function of tissues. L-carnosine has been studied for its ability to help protect proteins from glycation and provide antioxidant support, helping maintain healthy cellular function as part of the normal aging process.
  4. Is Swanson L-Carnosine suitable for special diets?
    Yes. Swanson L-Carnosine is non-GMO, gluten free, and dairy free. However, it is not suitable for vegan or vegetarian diets because the capsule contains gelatin.
