Blood Sugar and Vitamine C
Coventry, England? Warwick Medical School study, organized, long-term high blood sugar value 1 diabetic patients with long-term changes in the endothelial cells, which may contribute to endothelial dysfunction and is only in the normalization of glucose and oxidative stress (J Clin Endocrino Metab. 2009) (doi: 10.1210/jc.2009-0762). A total of 10 healthy volunteers and the three sub-10 1 diabetic persons who study at a (1) in patients, a month after diagnosis (2) 4.5 5.2 years, the patient diagnosis and HbA1c levels 7 percent, since the diagnosis, (3) in patients between 4.8 to 5.4 years from diagnosis and HbA1c levels by more than 7 percent, since the diagnosis. Each patient participated in three tests: (a) 24 hours after treatment with insulin, achieving near normalization of glycemia with the addition of the antioxidants vitamin C within the last 12 hours, (b) within 24 hours after the insulin Treatment with vitamin C in the last 12 hours, (c) treatment of vitamin C and insulin 24 hours.Endothelial function, as measured by the flow-mediated vasodilation (FMD) of brachial artery and the amount of nitrotyrosine is a marker for oxidative stress, for each treatment were normalized subgroups 1 and 2 In the third subgroup, no normalization of glucose and vitamin C was able to separate normalized endothelial dysfunction and oxidative stress. Combining insulin and vitamin C, but normalized endothelial dysfunction and nitrotyrosine.

What is a Vitamine?
Vitamin A is an organic compound required as a nutrient in tiny amounts by an organism. [1] A connection is a vitamin, if it is not synthesized in sufficient quantities by an organism, and must come from food. Thus, the term related to the circumstances and the organism. For example, ascorbic acid as vitamin C functions for some animals but not others, and vitamins D and K are in the human diet only in certain circumstances. [2] The term vitamin does not also other essential nutrients such as dietary minerals, essential fatty acids, or essential amino acids, yet it is also the large number of other nutrients, the health but are otherwise required less often. [3]
Vitamins are defined by their biological and chemical activity, not its structure. Thus, each "vitamin" may refer to several Vitam that all compounds, the biological activity associated with a particular vitamin. Such a set of chemicals are listed under a alphabetized vitamin "generic descriptor" title, such as "vitamin A", which also links retinal, retinol, and many carotenoids. [4] Inter-Vitam often in the body.
Vitamins have diverse biochemical functions, including function as hormones (eg vitamin D), antioxidants (eg vitamin E) and mediators of cell signaling and regulators of cell and tissue growth and differentiation (eg . Vitamin A). [5] The largest number of vitamins (eg B vitamins) as feedstock for bio-enzyme cofactor molecules (coenzymes), which help to act as catalysts and substrates in metabolism. If they are as part of a catalyst, vitamins are enzymes and are used as prosthetic group. For example, biotin is part of enzymes involved in the fatty acids. Vitamins as coenzymes to chemical groups of enzymes. For example, folic acid carries various forms of carbon group - methyl, formyl and methylene blue - in the cell. Although these roles in assisting enzyme reactions are vitamins' best-known function, the other vitamin functions are equally important [6].
Until the 1900s, vitamins were solely through food intake, and changes in diet (which, for example, could, during a growing season) the nature and amount of vitamin intake. Vitamins have been produced, such as chemical and made widely available as inexpensive pills for several decades, [7] to supplement the diet.
