What is Vitamin B3?

Vitamin B3 powder, also known as niacin, is an important nutrient. In fact, every part of your body needs it to function properly. As a supplement, vitamin B3 helps lower cholesterol, relieve arthritis, and enhance brain function, among other benefits. However, it can also cause serious side effects if you take large doses.

Vitamin B3 comes in two main chemical forms: niacin and niacinamide, both of which are found in foods and supplements. Niacin is water-soluble, so your body doesn't store it. This also means that your body can excrete excess vitamins through urine if not needed, so constant replenishment is required.

The key role of niacin in your body is to synthesize the coenzymes nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP), which are involved in more than 400 biochemical reactions in your body—mainly related to You get energy from the food you eat.

Functions of Vitamin B3 Powder

1. Improve blood lipid levels

Vitamin B3 powder can help improve your blood lipid levels by increasing your HDL (good) cholesterol or lowering your LDL (bad) LDL cholesterol or lowering your triglyceride levels, which can reduce the risk of risk of heart disease. 

High doses of niacin (usually 1,500 mg or more) can improve blood lipid levels, but may increase the risk of unpleasant or potentially harmful side effects. For these reasons, niacin is not the primary treatment for high cholesterol. It is primarily used to help improve blood lipid levels in people who cannot tolerate statins.

2. Can lower blood pressure

One of the effects of niacin is to release prostaglandins, or chemicals that help dilate blood vessels -- improving blood flow and lowering blood pressure. For this reason, niacin may play a role in preventing or treating high blood pressure.

3. May Help Treat Type 1 Diabetes

Type 1 diabetes is an autoimmune disease in which your body attacks and destroys insulin-producing cells in the pancreas. Studies have shown that vitamin b3 powder can help protect these cells and may even reduce the risk of developing type 1 diabetes in children who are at higher risk of developing the disease.

4. Enhance brain function

Your brain needs niacin -- as part of the coenzymes NAD and NADP -- to get energy and function properly. In fact, brain fog and even psychiatric symptoms have been linked to niacin deficiency.

Some types of schizophrenia can be treated with niacin because it helps to eliminate brain cell damage caused by niacin deficiency. Preliminary research suggests it may also help keep the brain healthy in the context of Alzheimer's disease. However, the results have been mixed.

5. Improves skin health

Niacin helps protect skin cells from sun damage, whether taken orally or as a lotion. It may also help prevent certain types of skin cancer.

Safety and Side Effects

There is no danger in consuming naturally occurring levels of niacin in food. However, supplemental doses may have various side effects, including nausea, vomiting, and liver toxicity.

Of particular note is a side effect called niacin flushing. This can happen when taking 30-50 mg or more of supplemental vitamin b3 powder in a single dose. It can cause redness and a burning or itching sensation on the skin. While the niacin flush itself is usually harmless, it can be accompanied by other unpleasant side effects, such as headaches or low blood pressure. Higher doses may cause liver damage or other serious side effects. You should consult with a trusted healthcare professional before starting to take niacin supplements.
