Guest guest Posted January 1, 2004 Report Share Posted January 1, 2004 Nidal, Far as I can tell, no academic/medicalstudies out on Inosine for CMT or PN. Looks like even for HIV-1 it is still in the rat-earthworm-pig experimental stages. China seems to be a popular place for making Inosine. This may be of interest - after the references, there is a section on " Frequently Asked Questions " . INOSINE Metabolically, inosine is an intermediate in a number of purine nucleotide pathways that affect the ability of the muscle to work efficiently. Some fitness experts claim that inosine can have a positive effect on overall physical strength and energy during exercise. Energy is what the muscles of athletes involved in aerobic, high-intensity exercise require. This short-duration energy requirement is produced by the breakdown of glycogen, which produces ATP (adenosine triphosphate), the currency of bodily energy. This is also called the aerobic pathway of energy production. After two to three minutes of intense exercise, aerobic pathway becomes the major source of energy production as the body begins to use oxygen to burn nutrients for energy. In aerobic metabolism, the body uses glucose, fatty acids and amino acids to produce energy that the muscles rely upon. Ultimate Nutrition's Premium Inosine supports the body in production of short bursts of energy during intense, aerobic exercise. Importantly, inosine increases the body's ability to handle rigorous exercise without inducing fatigue. What is Inosine? Inosine, also known as hypoxanthine riboside, belongs to a class of naturally occurring compounds called purine nucleotides, which are the building blocks of DNA and RNA. Adenosine in ATP is also a purine nucleotide. Inosine penetrates the cell walls of both the heart and skeletal muscle and, once inside the cell, promote the production of ATP, which helps the muscle to contract. In addition, inosine also facilitates the transport of oxygen from the circulating blood to various tissues in the body including the muscle. Combination of these two important properties makes it a valuable dietary supplement for athletes whose goal is to exercise for longer periods of time without experiencing muscle fatigue. Inosine is also known to activate various enzyme systems in the body, and it plays a crucial role in protein synthesis. Availability of abundant amounts of the protein in the muscle is necessary in order for the muscle to repair and grow, remodeling the tissue that the athletes need for performance. Furthermore, in aerobic energy production, protein is first broken down into amino acids before it can be used as a fuel to produce energy. Therefore, nutritional supplementation with inosine for enhanced performance during high-intensity aerobic exercise can hardly be overemphasized. Ultimate Nutrition's Premium Insoine Capsules guarantees the highest potency and maximal effectiveness in fulfilling your energy needs. Being of the highest quality, Premium Inosine not only provides a ready source of energy production but also supports faster muscle recovery and, simultaneously, helps the body to tone and remodel the muscle for enhanced performance.

K.: Wiley FREQUENTLY ASKED QUESTIONS 1.In What Natural Sources in Inosine Found? edible organ meats. 2.Does Inosine Have Any Health Benefits Beyond Athletic Sports? The major role of inosine in the cell is to produce energy and to help transport oxygen to various tissues. Even though inosine is presently used solely to provide bursts of energy in aerobic, active research is being carried out to discover any other potential applications of this invaluable nutritional supplement. 3.If Inosine and Adenosine Are Similar, Why Not Use Adenosine? While insoine and adenosine are chemically similar and belong to the same family of compounds, research has shown that nutritional supplementation with inosine, and not adenosine, high-intensity athletes derive the maximum benefit (see reference 5 above). 4.Could There Be Inosine Deficiency? Insoine is not an essential nutrient. That is, it is not absolutely required for growth and development. Consequently, inosine deficiency per se does not present itself. Its long-term deficiency, however, could clinically be discerned by several different criteria, such as lack of stamina and inability to maintain any activity that requires physical exertion, etc. 5.What is the Recommended daily Dosage of Inosine? Athletes tend to take rather large dosages of inosine, which can vary between 2000 milligrams to 5000 milligrams. To derive maximal benefits, dosages should be tailored to individual needs and tolerance levels. The help of a physical trainer and/or healthcare professional may also be necessary to determine optimal inosine dosage. 6.What Are the Side Effects? No side effects associated with the ingestion of inosine have been reported to-date. This product is no longer available. Quote Link to comment Share on other sites More sharing options...
