The human cardiovascular system is a closed blood distribution system where blood circulates through a network of vessels. The cardiovascular system and the lymphatic system form together the circulatory system. The cardiovascular system consists of the heart and blood vessels: arteries, veins and capillaries. The heart is a pomp that forces a constant blood circulation. The blood leaves the heart through arteries, and it comes back through veins. Blood pressure created by a beating heart is not sufficient to push blood through the entire cardiovascular system, in particular when it needs to travel upwards back to the heart. The work of the heart muscle is supported by pulsating veins and the valves in veins that prevent backflow. The role of the cardiovascular system consists in transporting oxygen and carbon dioxide between gas exchange organs and tissues, transporting nutrients absorbed in the small intestine to places where they are stored or used, transporting hormones from places where they are produced to cells, and removing redundant metabolic products from tissues to the liver and the kidneys. The cardiovascular system also plays an immunological role, maintains constant body temperature and participates in maintaining a constant pH level.                                                                                                                                                                                                                 



The most common heart and cardiovascular diseases are hypertension and atherosclerosis. Atherosclerosis usually leads to ischemic heart disease, which in turn often results in myocardial infarction (heart attack). The main causes of atherosclerosis and hypertension are obesity, lack of physical activity and tobacco smoking. Other cardiovascular conditions include heart failure, coronary heart diseases, stroke, and varicose veins. One of the fundamental risk factors for cardiovascular diseases are high cholesterol levels in blood serum. Total cholesterol level below 200mg/dl is considered normal, 200-250mg/dl is increased high, and 250mg/dl very high. Excess of cholesterol is harmful not only to the cardiovascular system – cholesterol is also the main component of gallstones.

Using Nef-Ra unblocks blood vessels, stabilizes cholesterol levels and hypertension. It reduces the risk of heart attack and prevents blood clots. Medical examinations of patients who have been using Nef-Ra confirm that their blood is absolutely clean and their cholesterol is reduced to standars levels.


I cannot recall for how long I did not go to a doctor, but when I finally went and did some tests I found out that my cholesterol levels were dramatically high: 750mg/dl. As this particular condition is not painful, I did not even know that I was practically on the brink of life and death. Obviously I started taking medication, and after I while I heard a radio ad for Nef-Fa and I started taking it together with my medication. It is incredible how much my results improved since I started using Nef-Ra: after three months my cholesterol level dropped to around 250, and after the next three months the doctor said that my results were exemplary. I persuaded my wife to start taking Nef-Ra too, as she had liver issues and had flatulence whenever she ate anything. And believe me, Nef-Ra helped her too. Now we both recommend this wonderful preparation to anyone who wants to be healthy and avoid taking medication for the rest of their lives. Walenty Z, Chicago,IL tel: 708/770-4472
