Vitamin B3 (niacin) - importance for skin health, cholesterol and digestive system

In today's article I will present in detail vitamin B3, also known as niacin or vitamin PP. We will discuss its role in the body, symptoms of deficiency, effects of excess, availability of this vitamin and its importance for skin health, cholesterol and digestive system.

Vitamin B3, vitamin PP, niacin - role in the body

Vitamin B3, also known as niacin, plays the role in many biochemical processes occurring in our body. It is a chemical compound from the group of vitamins B-chipks, which includes niacin (nicotine acid) and its amide, niacinamide (nicotinamide). It is also known as vitamin PP, which applies to its preventing properties of pelagar ("pellagra-reprementing"). Niacin is necessary for the proper functioning of the nervous system, the digestive system and for maintaining healthy skin. He also acts as a cofactor for many enzymes in our bodies that participate in energy metabolism, fat synthesis, cholesterol and DNA. In addition, vitamin B3 has the ability to dilate blood vessels, which can improve blood circulation. Niacin participates in:

• Oxidative and editorial metabolic reactions, such as glycolis, Krebs cycle.
• Cholesterol synthesis and fatty acids.
• Cell protection against oxidative stress.

Vitamin B3 - Symptoms of deficiency

Vitamin B3 deficiency can lead to serious health consequences. The most famous disease associated with its deficiency is Pelagra, which manifests itself through the so -called "Three D": Dermatitis (dermatitis), Diarrhea (diarrhea), Dementia (dementia). Other symptoms of vitamin B3 deficiency are:

• Fatigue and weakness
• Headaches
• Loss of appetite
• Depression and irritability
• Digestive problems
• Skin lesions and hypersensitivity to light

The symptoms described can be confused with other diseases, so it is important to accurately diagnose by a specialist.

What does excess vitamin B3 mean?

Taking excessive doses of niacin, especially in the form of supplements, can lead to toxicity and various undesirable health effects. Excess vitamin B3 can cause:

• Redness and burning of the skin, known as "Flush effect".
• Nausea and vomiting
• Liver problems such as increased hepatic enzymes
• Increased risk of type 2 diabetes
• Heart arrhythmias

Long -term high doses can lead to serious health problems, so you should always consult a doctor before starting to supplement with vitamin B3.

Vitamin B3 - where does it occur?

Niacin is widespread in many food products, both plant and animal origin. Vitamin B3 food sources include:

• Meat: Beef, pork, poultry.
• Fish: Tuna, salmon.
• Cereal products: Whole grain bread, brown rice, bran.
• Nuts: Peanuts, hazelnuts.
• Vegetables: Peas, potatoes, broccoli.

It is important that the diet varies and contain products rich in niacin to provide the body with the right amount of this vitamin each day.

The importance of vitamin B3 for skin health, cholesterol and digestive system

Niacin plays an important role in maintaining skin health. It is used in creams and ointments for atopic dermatitis, acne and other skin lesions due to its anti -inflammatory and antioxidant effects. Niacinamide, niacin form, is particularly effective in improving the function of the skin barrier, which contributes to increased skin hydration and protection against external factors. Niacin also has a positive effect on the lipid profile. Reducing LDL cholesterol (so-called "bad" cholesterol) and triglycerides as well as an increase in HDL cholesterol (so-called "good" cholesterol) can help reduce the risk of atherosclerosis and cardiovascular disease. In the digestive system, niacin supports digestive processes and helps in the metabolism of carbohydrates, fats and proteins, which is necessary to maintain adequate body weight and metabolic health.

Summary

Vitamin B3, known as niacin or vitamin PP, is an essential nutrient that plays an important role in many biochemical processes of the body. Its deficiency can lead to serious health problems such as Pelagra, while excess can cause toxicity. It is worth taking care of a diverse diet that provides the right amounts of vitamin B3, and in the case of supplementation to consult a doctor. Niacin is also important for the health of the skin, cholesterol and digestive system, which makes it an indispensable part of a healthy diet.
