The health benefits of Niacin are well documented. It has been used to treat and cure a number of medical maladies, sometimes more effectively than current drug therapy. Because of this, much of the data has been suppressed by the pharmaceutical industry.
For fifty years, Niacin has been extensively used to support healthy metabolism and circulation. Through many clinical trials, Niacin has proven to be effective at elevating HDL (good cholesterol) and lowering LDL (bad cholesterol). It also helps widen your blood vessels which helps your arteries relax by increasing Nitric Oxide synthase.
For many years the medical industry has operated under the assumption that elevated cholesterol levels were a significant risk factor for coronary artery disease (CAD). Recently, it was discovered that 75% of all heart attack patients admitted to hospitals had total cholesterol levels that were considered to be safe. We now know that oxidized LDL is the real danger. Niacin increases NADP, which inhibits LDL oxidation.
Mitochondria, your cellular "engines," convert food to energy (ATP) through a complex process similar to a production line in a factory. When someone on the production line is not able to keep pace, it affects every subsequent step in the process. Niacin is the backbone of two enzymes known as NAD and NADP (think of these enzymes as employees on the production line who perform an important role in how your cells make energy). They are also "team players," helping as many as 200 other energy-related enzymes do their work. The ability of your body to break down fats, carbohydrates, and proteins and use them to make energy is dependent on having adequate niacin. NIacin plays a role in mobilizing stored fat, and it prevents the storage of excess fat. It also helps with the breakdown and utilization of carbohydrates, sugar and protein. All these work together to maintain a healthy, lean body.
Niacin also plays many other roles, including assisting your DNA to repair itself. Niacin is especially active in your circulatory system. Niacin can assist with fatigue, weakness, skin irritations, appetite, mood, and mild headaches.
Niacin is best known for its role in supporting HDL cholesterol metabolism, helping maintain healthy levels of HDL and its very important component, ApoA1. Niacin also helps your body metabolize triglycerides in a healthy way. Overall, niacin is an excellent cardiovascular support nutrient.
