Astaxanthin is a natural carotenoid widely found in algae, fungi, and crustaceans. It possesses multiple biological functions including antioxidant, anti-inflammatory, immune-enhancing, and reproduction-promoting effects, making it one of the most potent natural antioxidants known.

• Antioxidant effect: Scavenges free radicals and exerts antioxidant activity, protecting membrane phospholipids and preventing peroxidation of other lipids.
  
• Anti-stress effect: Enhances immunity, alleviates stress, improves animal health, and increases the nutritional value of aquatic products.
• Improves reproductive performance: Increases the survival rate of juvenile shrimp, as well as egg buoyancy and survival rate in fish.
• Coloring effect: Enhances pigmentation in fish and crustaceans and increases the concentration of astaxanthin in tissues.
