L-Citrulline is used for Alzheimer's disease, Dementia, fatigue, muscle weakness,Sickle Cell disease, erectile dysfunction, high blood pressure, and diabetes. It isused for heart disease, body building, increasing energy and for improving athleticperformance.L-Citrulline is thought to help increase the supply of ingredients the body needs to make certain proteins. It may also help open up veins and arteries to improve blood flow and reduce blood pressure.The following are the primary scientifically backed reasons why one should consider adding L-Arginine to their health and wellness regimen.1. Offers wide-ranging cardiovascular support, including controlling blood pressure and plaque formation. Nitric oxide keeps arteries relaxed and pliable for normal blood pressure, preventing hypertension and angina.2. L-Arginine is one thousand times more powerful than any naturally occurring antioxidant in the body. L-Arginine's antioxidant properties support various body systems and may protect against heart disease, stroke, cancer and diabetes, as well as slowing premature aging.3. Enhances memory, particularly long-term memory, and may help to reverse the effects of dementia and Alzheimer's disease.4. Boosts human growth hormone (HGH) production, which has anti-aging properties. 5. May help improve immune function and fight bacterial infections.6. May help in the treatment and prevention of diabetes since many disease complications, including poor circulation and blindness are vascular in nature. L-Arginine is also foundto regulate insulin secretion in the pancreas.7. Enhances male sexual performance by treating vascular erectile dysfunction (ED). 8. L-Arginine's anticoagulant abilities reduce clotting and lower heart attack and stroke risk.9. Reduces pregnancy-related hypertension, a risk factor for both the expecting mother and the unborn child.10. Useful in the treatment of asthma by opening pulmonary pathways for easier breathing and the treatment of lung disorders.11. Boosts lean muscle mass and preserves bone density by encouraging HGH production, which also leads to a reduction in fatty tissue. Because of these properties, it may be useful in weight management and strength training.12. Can help offset cardiovascular and lung damage caused by tobacco use, since nitric oxidelevels in smokers are less than half of those found in non-smokers.
