If you want an immune boost or to help elevate mood (yes it does help mood!) you might consider getting IP-6 alone, but THIS supplement has extras (cat's claw and mushrooms) that make it superior to many immune support supplements. Not a bad idea to start taking this before winter and/or flu season every year, and maintain until spring allergy season clears. Powerful antioxidant!
