This book highlights the nano-antioxidants and their potential therapeutic applications. The chapters start with basic information on free radicals and antioxidants, through natural antioxidants, mechanisms of their action, ending with the use of nano-antioxidants particularly its potential therapeutic applications. Nano-antioxidant therapy has a promising future that has to be explored. It is a bridge topic to connect the already existing literature with potential therapeutic highlights. This book is designated for students and researchers interested in Biochemistry, Chemistry, Physics, Food Science and nutrition, Pharmaceutical Science and Medicine. It would also be interesting to global audiences from human and animal nutrition to food preservation and packaging.
