Niacin is a B vitamin proven to reverse the effects of bad cholesterol and increase levels of good cholesterol. It has consistently shown to impact prognosis in patients of cholesterol-related illnesses. There is very strong scientific evidence that it prevents the formation of plaques within the linings of arteries by curbing the release of free fatty acids into the bloodstream and facilitates recovery against coronary heart disease and atherosclerosis by managing lipoproteins that cause thrombosis.
Cholesterol
The organic compound that promotes the functional permeability of cell membranes and the viscosity of the lipid bilayer that makes up the cell membranes is called cholesterol. It is vital to human life. A significant fraction is synthesized in the liver and distributed to all cells by way of the bloodstream. In the cell membrane it regulates traffic of signaling molecules in and out of cells, acting as guardians in gateways called lipid rafts. It is also converted to bile and released to the small intestine, being a precursor to the fat-soluble vitamins A, D, E, and K.
Triglycerides
Free fatty acids from the foods we eat are usually stored in triglycerides, which are broken down into smaller particles to be absorbed by the intestinal walls. Once they reach the liver, they are reformed into triglycerides to function as transports for cholesterol, which is not released into the bloodstream without the former. Triglycerides make up a part of organic compounds that display both hydrophilic and lipophilic properties, making an ideal transport in the water-based blood plasma.
Lipoproteins
What we refer to as bad cholesterol are actually a group of biomolecules called lipoproteins whose structures comprise features of both proteins and lipids. Triglycerides are a major constituent of these lipoproteins, the bigger transports of triglycerides. The dichotomy of bad versus good cholesterol has surfaced in recent years owing to the fact that cardiovascular tissues attract some lipoproteins to accumulate in the arterial walls, which leads to the thinning of the arteries and the obstruction of normal blood flow. These notorious lipoproteins are also responsible for the formation of blood clots.
Low-Density Lipoproteins
While cholesterol is a good indicator of cardiovascular diseases, the real risk lies in elevated levels of triglycerides and low-density lipoproteins, which carry cholesterol in the bloodstream. Other types of lipoproteins, also dubbed bad cholesterol, known as very-low-density lipoproteins transport other lipids to body cells. These two groups of lipoproteins pose higher risk factors for coronary heart disease and atherosclerosis and is the target of cholesterol-lowering drugs.
High-Density Lipoproteins
The types of lipoproteins that transport cholesterol from the cells back to the liver for excretion are called high-density lipoproteins, which are identified as the good cholesterol as they do not get entrenched in the blood vessel walls. The mechanism of action by which niacin helps cholesterol serum levels is twofold: it raises levels of high-density lipoproteins and lowers low-density lipoproteins, or colloquially speaking, more good cholesterol, less bad cholesterol.
Niacin can help against the fight with high cholesterol levels. You can find niacin at your local or internet vitamin store in 100mg, 500mg, or 1000mg dosages. Always choose name brands like Solaray to ensure quality of the niacin you buy for better health.
