Niacin effect and what is vitamin B3 important for? – Here is everything you need to know!

For our body to remain healthy and efficient, it needs all vitamins in sufficient quantities. Our blood, bones, skin, organs, eyes and nerves need vitamins to function. If you eat a balanced diet, you can usually get the recommended amount of vitamins. While we all know what vitamins A, C and D are important for, most of us don’t know what vitamin B3 is good for. Vitamin B3, also still known as niacin, is one of the eight B vitamins and is essential for numerous metabolic processes in the body, such as the production of fatty acids and cell division. It also ensures healthy skin, the regeneration of muscles and nerves, and can lower cholesterol levels. But what is niacin and what foods contain it? Read on to learn everything you need to know about niacin effects and functions.

What is niacin?

Niacin is also still known as vitamin B3 and belongs to the group of water-soluble B vitamins . It is the generic term for two related compounds with vitamin effects – nicotinamide and nicotinic acid. Nicotinic acid can lower cholesterol and reduce the risk of heart disease. Niacinamide, on the other hand, can help treat psoriasis and prevent skin cancer. These are converted by the body into the biologically active form vitamin B3. Since it can be absorbed not only through food, but also produced by the human body itself, it is actually not a vitamin in the classical sense. Niacin is found in all living cells of the body, but its concentration is highest in kidneys, fatty tissue and liver. It is enormously important for the normal functioning of the nervous system and is involved in the formation and breakdown of carbohydrates. It also supports the health of the skin and mucous membranes and helps reduce fatigue.

What is the daily requirement and what are the symptoms of a niacin deficiency?

How much niacin the body needs depends on various factors, including age, gender and energy requirements. The German Nutrition Society recommends the following values for daily vitamin B3 intake:

  • Children and adolescents: 8 to 17 mg
  • Adult women: 13 to 17 mg
  • Adult men: 14 to 17 mg
  • Pregnant women: 14 to 16 mg
  • Breastfeeding women: 16 mg

The daily requirement is covered on the one hand by food and on the other hand by the body’s own production. Alcoholics and people with chronic intestinal inflammations have an increased requirement. Niacin deficiency is quite rare in Western countries and first becomes noticeable through non-specific symptoms such as loss of appetite and physical weakness. Although niacin deficiency is rare, in some cases niacin overdose can have negative side effects such as skin redness, itching, liver damage, or even gastrointestinal distress. So if you don’t have a proven deficiency, then you should avoid supplements. Here are some of the most common symptoms of vitamin B3 deficiency:

  • Severe headaches
  • Skin problems and inflammation
  • Diarrhea
  • Fatigue
  • Memory loss and mental confusion
  • Depression
  • If left untreated, niacin deficiency can lead to pellagra, which can cause multi-organ failure.

  • Amply moisturizes and strengthens the protective function of the skin – Niacin supports the formation of ceramides and lipids – substances that are essential for the protective function of the skin. A healthy skin barrier makes the skin more resistant to external influences and, above all, ensures that the skin loses less moisture.
