Research has proven that nitric oxide is what the body uses to stimulate your blood vessels to expand and contract to keep blood pressure in check. L-citrulline is one of the three dietary amino acids in the urea cycle, alongside L-arginine and L-ornithine. Men and women with poor circulation, high blood pressure, high cholesterol and many common health problems are often deficient in the critical molecule nitric oxide. With enough L-arginine, L-ornithine, and L-citrulline, according to the research, you can reverse the deficiency and dramatically improve your cardiovascular and overall health. The Journal of Advanced Research did an analysis on L-arginine studies that includes the amino acids ornithine and citrulline since they also work in the same pathway.
Recommended Uses: 3-4 capsules before your workout and before bed.
Many human and animal studies have shown that when taken in the right dosages, these amino acids have multiple beneficial pharmacological effects such as reduction in the risk of vascular and heart diseases, reduction in erectile dysfunction, improvement in immune response and inhibition of gastric hyperacidity. The demonstrated anti-aging benefits of L-arginine, ornithine, and citrulline show greater potential than any other nutraceutical agent ever previously discovered, according to the Journal. (Anti-aging effects of L-arginine, Cairo University, Journal of Advanced Research;17 June 2009; Dept. of Biochemistry, Faculty of Pharmacy and Biotechnology).
Research shows that L-arginine alone works great to improve nitric oxide levels in the body, especially in age groups under 30. After the age of 30, L-arginine’s effectiveness alone can be diminished because of oxidation and the bodies ability to use just the arginine pathway for nitric conversion.
Studies show there are two ways to help with this problem. Argi-Pump utilizes all three amino acids the body uses for this pathway and is why ornithine and citrulline are utilized. Sustained release is important for arginine to have long-term benefits to circulation and stimulation. Special forms of arginine such as AAK are stabilized for sustained release. Arginine, ornithine, and citrulline have research showing that when taken orally in the right amounts can:
- Be a precursor for the synthesis of nitric oxide (NO).
- Stimulate growth hormone for anti-aging benefits.
- Counter heart disease and aid in blood pressure regulation.
- Improve insulin sensitivity to help normalize blood sugar.
- Bolster the immune system, boost energy, and increase lean muscle.
- Promote reproductive health.
- Be a natural alternative for Viagra.
- Increase fertility and pleasure sensation in women.
L-arginine, ornithine or citrulline are not hormones or testosterone. These are amino acids. When properly brought into the body they're proven to cross the blood-brain barrier to signal the hypothalamus to naturally trigger the pituitary gland to produce growth hormone. This is the key to eliminating any negative side effects. Columbia University refers to L-arginine as the “MAGIC BULLET” for the cardiovascular system. Columbia’s researchers have compiled over 10,000 citations and even include L-arginine in its course material.
Dosage is everything. Most arginine-based supplements don’t provide the amounts needed to induce nitric oxide (N.O.) responses. Doses of L-arginine, ornithine, and citrulline vary based on the research studies examined. Typical daily doses for nitric oxide production and regulation of blood pressure range from 2-4,000 milligrams (2-4 grams). This is the amount needed to elicit the nitric oxide response. Each 2 capsule serving of Optimal Argi-Pump contains 2 grams. Studies focusing on more serious acute conditions have utilized daily dosages from 6-9,000 milligrams. Consult with your physician for proper dosing.
