Niacin, also known as vitamin B3, is an important nutrient that is part of the B vitamin family. It is used by the body to turn food into energy and helps keep the nervous system, digestive system, and skin healthy. Niacin is a major component of NAD and NADP, two coenzymes involved in cellular metabolism, and plays a role in cell signaling and making and repairing DNA, in addition to acting as an antioxidant. Some benefits of niacin include:

• Lowering cholesterol: Niacin can improve cholesterol levels by boosting levels of good HDL cholesterol and lowering triglycerides. It also modestly lowers bad LDL cholesterol.

• Treating type 1 diabetes: Research suggests that niacin could help protect insulin-creating cells and possibly even lower the risk of type 1 diabetes in children who have a higher chance of developing this condition.

• Improving brain health: Population studies show that people who get higher levels of niacin in their diet have a lower risk of Alzheimers disease.

• Preventing skin cancer: Niacinamide, a form of niacin, has been shown to reduce the risk of developing certain types of skin cancer.

However, high doses of niacin can cause unpleasant and even dangerous side effects, such as flushing of the skin, stomach upset, headache, dizziness, blurred vision, and an increased risk of liver damage. Therefore, it is important to consult a doctor before taking niacin supplements, especially if you have any health conditions or are taking other medications.
