Niacin: What Vitamin?

Health benefits

Niacin, also known as vitamin B3, is an essential nutrient that plays an important role in keeping the body healthy. It helps to regulate many metabolic functions, including energy production, hormone production, and neurotransmitter synthesis. It can also help to reduce inflammation and lower levels of fat in the blood. The most common health benefits of niacin include improved cholesterol levels, reduced oxidative stress, improved digestion and liver function, and improved skin health. Additionally, niacin may have some beneficial effects on heart health, including reducing the risk of heart attack and stroke. People who are deficient in niacin should supplement with a multivitamin containing this essential vitamin. Niacin has also been studied as a potential treatment for conditions such as Alzheimer’s disease, migraines, and depression.

Sources of niacin

Niacin, also known as vitamin B3, is an important nutrient for the human body. It is essential for cell growth, DNA repair and energy production. While the body produces small amounts of niacin naturally, it must be obtained from external sources. Common sources of niacin include enriched grains, legumes, peanuts, eggs, and red meat. Fish, such as tuna and salmon, are also high in niacin. Dairy products, including yogurt and cheese, are also great sources of niacin. Additionally, niacin can be found in certain fruits, such as oranges and avocados, as well as vegetables, such as broccoli and mushrooms. Finally, many multivitamins contain niacin, making it an easy way for individuals to get the nutrient. All of these sources make it easy to get enough niacin in one’s diet.


Niacin is a vitamin that plays an important role in the body’s metabolism. The recommended daily allowance (RDA) for niacin is 14 mg per day for adults. This amount can be obtained through dietary sources such as meats, fish, eggs, and fortified foods, but for those who are unable to get enough niacin from their diets, supplementation is recommended. For certain medical conditions, a doctor may recommend higher doses of niacin as a supplement. In these cases, side effects such as flushing and itching may occur. Niacin supplements are available in most health food stores, pharmacies and supermarkets. It is important to ask your doctor before taking any type of niacin supplement, as it can interact with certain medications.

Deficiency symptoms

Vitamin B3, commonly referred to as Niacin, is a crucial nutrient that is needed for many important bodily functions. Unfortunately, a Niacin deficiency can lead to a variety of severe symptoms. While it is possible to get enough Niacin from the foods we eat, a deficiency can occur if an individual’s diet is lacking in the vitamin or if their body cannot adequately absorb it. Some of the most common deficiency symptoms are irritability, poor concentration, fatigue, digestive issues, poor muscle coordination, red and scaly skin rashes, and even leg cramps. A doctor can diagnose a Niacin deficiency, as well as determine whether a supplement is necessary.

Side effects

Niacin, also known as vitamin B3, is a vital component for keeping the body healthy and functioning at its best. It has many medicinal benefits, including helping with cholesterol levels, skin conditions and other metabolic functions. However, even when taken as instructed, niacin can cause some side effects. These can include nausea, skin flushing, abdominal pain, headaches and an increased heart rate. In extreme cases, niacin can be dangerous, leading to liver damage and high blood pressure levels. Due to this, anyone thinking of taking a niacin supplement should speak to a medical professional before doing so. If you experience any of these symptoms while taking niacin, be sure to get medical attention right away.
