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. When you combine that with the fact that the brain is the least able to repair itself of any tissue in your body, it is pretty obvious why the brain is spending a lot of energy pumping antioxidants into itself. Your mitochondria are the power plants of your cells, burning fuel to produce the universal energy molecule ATP, as well as a very dangerous type of toxic waste, uncontrolled free radicals. B2 is an essential part of the mitochondrial electron transfer flavoproteins, flavin mononucleotides, and flavin adenine dinucleotides in both their reduced and oxidized forms. B2 is also a cofactor of glutathione reductase, which plays a role in reducing the pro-oxidant ascorbyl radical back to the antioxidant vitamin C. B3 is an essential part of nicotinamide adenine dinucleotide and nicotinamide dinucleotide phosphate in both reduced and oxidized forms.
Taurine is a very important antioxidant.
It is also pumped into your heart. It protects electrically active tissues like the brain and heart, your retinas and optic nerves from overexcitation. Moreover, taurine also helps provide protection against excitotoxin damage which happens as a result of ordinary living and probably contributes to the aging process as well. Niacinamide, a form of vitamin B3, is also protective against excitotoxins and that's also in the Smart Boost R . They do a lot of damage to the long lived tissue in your body such as collagen.
