In the anti-aging book "Bombshell," by Suzanne Somers, Dr.Michael Galitzer, M.D., says "Large doses of vitamin C stimulate the immune system, help the liver work better, and strengthen our adrenals." In the same book, Dr. Jonathan Wright, M.D., states "... at the top of my list is taking 3,000 milligrams of vitamin D daily. That is based on research. Vitamin C is the major detoxifier for nearly every living thing. Dr. Pauling said that one should take vitamin C three times a day because it's a water-soluble vitamin, meaning it runs through the body rapidly. Researchers at UCLA did a longevity study with several thousand people over a period of seven years They kept track of what they ate and the vitamins they took. They found that men who took 800- 1,000 milligrams of vitamin C a day could expect to live six years longer." (website editor: these are educational examples only, and not meant as advice)

Vitamin C May Benefit Eyes, Brain
Vitamin C is a major antioxidant and one of the most important nutrients for human health, playing a role in more than 300 physiological processes. Now, preliminary research published in the journal Neuroscience*, suggests that vitamin C may be a key regulator of retinal and brain function.
Gamma-aminobutyric acid, or GABA, is the chief excitatory neurotransmitter in the human brain and has responsibility for regulating the brain’s chemical messages. It’s estimated that GABA is present in forty percent of brain synapses. (Synapses are the gaps between neurons, nerve cells responsible for processing and communicating information within the brain. Synapses allow information to pass from one neuron to the next.)
Researchers at Oregon Health and Science University studied the effects of vitamin C on GABA-receptor cells found in goldfish retinas. (Goldfish retinas have the same biological structure as human retinas.) They found that the GABA-type receptors needed to be "bathed" in vitamin C in order to function properly. Conversely, when vitamin C was removed, the GABA-type receptors stopped functioning properly. Given the importance of GABA in brain function, this suggests a possibly powerful role of vitamin C in brain function.
Dr. Henrique von Gersdorff, PhD, who co-authored the study, suggested that this effect may be due to vitamin C’s antioxidant activities. "Because vitamin C is a major natural antioxidant, it may be that it essentially ‘preserves’ the receptors and cells from premature breakdown." Although the exact mechanisms of how vitamin C affects brain function are still unknown, it is known that when the human body is deprived of vitamin C, it stays in the brain longer than any other place in the human body.
The OHSU research may provide clues as to why people who suffer from scurvy, a disease of vitamin C deficiency, also frequently suffer from depression. It may also have implications for future treatments for other diseases that result when GABA receptors do not function properly, such as glaucoma and epilepsy."For example, maybe a vitamin C-rich diet could be neuroprotective for the retina – for people who are especially prone to glaucoma," suggested von Gersdorff. He added that "this is speculative and there is much to learn. But this research provides some important insights and will lead to the generation of new hypotheses and potential treatment strategies." (youngevity.com)
