The study shows that older people who eat plenty of vitamin C -- commonly found in citrus fruits, berries and vegetables -- have the best skeletal muscle mass.

A probe chemical emitted red fluorescent light after reacting with vitamin C in the mice's bloodstream. When a dose of exogenous vitamin C was injected, it accumulated in vital organs. This is the first bioimaging of vitamin C in living tissue, showing high sensitivity and good selectivity, paving the way toward the use of this vitamin to treat cancer.

The device, called OcuCheck, measures levels of vitamin C in the fluids that coat or leak from the eye. The sensor could speed efforts to determine the extent of eye injuries at accident sites or on the battlefield, the researchers said.

Vitamin C supplementation, alone or in combination with allopurinol, appears to have a weak effect on lowering uric acid levels in gout patients, according to the results of a new study.

Women who ate high amounts of the compound had a 19 percent lower risk of ischemic stroke than women who consumed the least amount.

Wed, 28 Sep 2011 12:54:16 EDT //www.koonmotors.com/releases/2011/09/110928125416.htm //www.koonmotors.com/releases/2011/08/110805082957.htm In summer, more dishes like gazpacho –- a cold soup containing raw vegetables, bread, olive oil and vinegar –- are consumed. A new study has revealed that ingredients’ vitamin C content as well as other organic acids is lower in the resulting mixture, meaning that it should be eaten immediately after preparation.

Crystalline substances are prone to a process called deliquescence, in which humidity causes a water-soluble solid to dissolve. Keeping vitamins and supplements away from warm, humid environments can help ensure their effectiveness. Tue, 02 Mar 2010 16:22:57 EST //www.koonmotors.com/releases/2010/03/100302162257.htm //www.koonmotors.com/releases/2010/03/100301173818.htm Vitamin C is indispensible for life. We obtain all our vitamin C from out diet and several tightly regulated processes control our vitamin C levels. One protein involved in this is Slc23a1, but its in vivo importance has not been determined. However, researchers have now identified several crucial functions for Slc23a1 in mice: it is involved in absorption of vitamin C by the kidney and in perinatal survival.

This finding has been possible owing to a new technique developed by the researchers to determine the content of vitamin C in these kinds of drinks.

Thu, 05 Mar 2009 14:16:56 EST //www.koonmotors.com/releases/2009/03/090305141656.htm //www.koonmotors.com/releases/2008/08/080804190645.htm High-dose injections of vitamin C, also known as ascorbate or ascorbic acid, reduced tumor weight and growth rate by about 50 percent in mouse models of brain, ovarian and pancreatic cancers, researchers report in the Proceedings of the National Academy of Sciences. The researchers traced ascorbate's anti-cancer effect to the formation of hydrogen peroxide in the extracellular fluid surrounding the tumors. Normal cells were unaffected.

Citrus juices enable more of green tea's unique antioxidants to remain after simulated digestion, making the pairing even healthier than previously thought.

Fat remains in the proximal stomach for some time after a meal and also makes up a substantial amount of the cells lining the stomach, say the authors. Mon, 03 Sep 2007 20:48:00 EDT //www.koonmotors.com/releases/2007/09/070903204800.htm //www.koonmotors.com/releases/2007/07/070718002136.htm Unless you run marathons, you probably won't get much protection from common colds by taking a daily supplemental dose of vitamin C, according to an updated review of 30 studies. Wed, 18 Jul 2007 00:21:36 EDT //www.koonmotors.com/releases/2007/07/070718002136.htm //www.koonmotors.com/releases/2006/02/060224104219.htm A new study has found that supplements of vitamin C can largely stop the serious depletion of vitamin E that occurs in smokers, demonstrating for the first time in humans a remarkable interaction between these two antioxidants as they work together. The research also suggests a possible mechanism by which smoking can cause cancer.

All this, despite a loss of vitamin C during the cooking process, say Cornell food scientists. The reason: cooking substantially raises the levels of beneficial compounds called phytochemicals. Mon, 22 Apr 2002 07:33:41 EDT //www.koonmotors.com/releases/2002/04/020422073341.htm //www.koonmotors.com/releases/2001/04/010411082248.htm Low levels of vitamin C in the blood are linked to a more severe form of peripheral artery disease, an often painful condition in which the leg blood vessels become blocked, according to a report in Circulation: Journal of the American Heart Association. Wed, 11 Apr 2001 08:22:48 EDT //www.koonmotors.com/releases/2001/04/010411082248.htm //www.koonmotors.com/releases/2000/06/000625232319.htm Time to adjust an old adage: It's the phytochemicals in the apple each day that keep the doctor away. A combination of plant chemicals, such as flavanoids and polyphenols -- collectively known as phytochemicals -- found both within the flesh of apple and particularly in the skin -- provide the fruit's anti-oxidant and anti-cancer benefits, say Cornell food scientists.

This finding may prove useful in efforts to slow the progression of certain neurodegenerative diseases, such as Alzheimer's.
