Experts have recently found out that diabetes mellitus produces excessive competition for L-arginine, a type of amino acid, which aids in making the blood vessels to relax. This essential amino acid is metabolized in the body by the enzyme called arginase to the compound, urea, which in turn aids the body to effectively eliminate toxic substances that is caused by the proteins from the foods that we consume.
According to medical experts, people suffering from diabetes tend to have a lot of arginase enzyme activity, which only implies that they tend to utilize more amounts of the amino acid L-arginine. In addition to this, this also implies that very few amounts of this amino acid is available to aid the enzyme, nitric oxide synthase to produce nitric oxide, the potent compound in vasodilatation, helping the blood vessels to relax more.
Also, it was found as well, that L-citrulline, another type of amino acid, and also statins, compounds that are known to lessen blood cholesterol, prevent the elevation of the enzyme arginase activity, thereby bringing back the normal dilation capabilities in animal models suffering from a case of type 1 diabetes mellitus. The truth of the matter is that, the amino acid L-citrulline is recyclable to L-arginine.
The outcomes of recent research may also explain why supplements of L-arginine that were marketed as treatment for heart failure, chest pain, hypertension and many others may not work on a long term basis. Tests are still being conducted however since there have been many positive reported affects from people that religiously use this supplement for its many reported health benefits.
However, patients who utilize and rely on L-arginine supplements for the sole purpose of prevention of heart attack and/or hypertension should exercise caution. Nothing should be a replacement for good life choices such as exercise and diet. There isn’t anything that can be taken as a supplement that should be considered more important than a good diet when it comes to prevention of a heart attack.
According to health experts, the elevated activity of the arginase enzyme in diabetes mellitus may restrain other therapeutic approaches that were recommended for initial endothelial dysfunction like oral supplementation of L-arginine. Dietary supplementation of L-arginine however, has been indicated to exert protective functions in particular clinical settings.
In addition to this, experts say that a temporary course of L-arginine administered intravenously may give short-term improvement to the tone of the blood vessel. However, majority of arginine that is directly taken goes directly to the liver, and consequently being metabolized instead of going to the bloodstream where it can trigger blood vessel relaxation.
Aside from assisting the body to transform toxic substances to urea that could be entirely eliminated from the body system, the enzyme arginase as well aids in the formation of collagen and proliferation of cells although excessive amounts can be detrimental. While L-arginine appears to exert many health benefits, it’s a supplement and a supplement is just that. It’s meant to be used alongside other healthy choices in one’s daily regime, such as diet and exercise. It should be never be used to replace anything or give one an excuse to exercise poor judgment in other areas of their life.
