Top Three Science Backed Benefits of Vitamin B3 (Niacin)
Niacin along with all other B vitamins helps change food into energy by assisting enzymes do their job. B3 is an integral component of NAD and NADP, which are two coenzymes that are involved in cellular metabolism. Niacin also plays a very important role as an antioxidant, heart health, making and repairing DNA and cell signaling. If you do not get the right amount of Niacin then you can suffer from fatigue, depression, diarrhea, headache, skin issues, memory loss and confusion
Niacin’s first benefit for blood fats is that it can lower triglycerides by 20–50% (7).
It does this by stopping the action of an enzyme that’s involved in triglyceride synthesis (1).
Consequently, this lowers the production of low-density lipoprotein (LDL) and very low-density lipoprotein (VLDL). Therapeutic doses are needed to achieve these effects on cholesterol and triglyceride levels (1).
Reduces LDL Cholesterol
Niacin has been used since the 1950s to treat high cholesterol. In fact, it can lower levels of “bad” LDL cholesterol by 5–20%. However, niacin is not the primary treatment for high cholesterol due to its possible side effects. Rather, it’s primarily used as a cholesterol-lowering treatment for people who can’t tolerate statins.
Raises HDL Cholesterol
Along with reducing LDL cholesterol, niacin also raises “good” HDL cholesterol. It does this by helping to stop the breakdown of apolipoprotein A1, a protein that helps make HDL. Studies have shown that niacin raises HDL cholesterol levels by 15–35%.
