The antioxidant nutrients in Smart Boost R work together as an integrated system. The unpaired electron on this radical is less dangerously reactive than the original hydroxyl radical, but it is still potentially destructive. A vitamin C molecule can recycle the tocopherol radical back to the antioxidant vitamin E, but the C becomes a pro-oxidant ascorbyl radical, which can be recyced back to antioxidant vitamin C with the help of vitamin B2 dependent glutathione reductase, which in turn requires a B3 dependent reductant. Controlling free radicals in your body requires a free radical scavenging cascade, an integrated system of antioxidants and cofactors, not just one magic bullet antioxidant nutrient and not just a random collection of antioxidants. Well, it is for those who want to increase their C and E and other nutrients like B2 and B3 that work with them to help keep free radicals under control.
Free radicals are atoms or molecules with an unpaired electron.
Because of the symmetries of space-time and the equations of quantum mechanics, molecules with paired electrons are much less promiscuously chemically reactive than those with an unpaired electron. There is 10 times as much C in your cerebral spinal fluid, which surrounds your brain and spinal cord, as there is in your general circulation. Vitamin C is concentrated 100 times more than the general circulation within each brain cell. The brain also has a very high specific metabolic activity so it is burning an awful lot of fuel in the mitochondria, producing a lot of free radicals. Free radicals are a normal and essential part of mitochondrial metabolism, and are normally routed through a safe system dependent on both B2 and B3.
