Vitamin B3 & Niacin: How They Work?

What Are B Vitamins?

B Vitamins are important nutrients that help maintain the balance of our bodies. They include B12, B6, folic acid, and B3, also known as niacin.

What is B3 Vitamin (Niacin)?

B3 vitamin, also known as niacin, is a crucial B vitamin that plays a vital role in keeping our bodies functioning properly.

There are two main forms of B3 vitamin:

• Nicotinic acid
• Niacinamide (sometimes called nicotinamide)
  
  

Both forms can be found in foods and dietary supplements.

The Role of Niacin

Niacin, or B3 vitamin, is a water-soluble vitamin, which means our bodies don’t store it. Instead, any excess is eliminated through urine.

We can obtain this essential nutrient through our diet, and our bodies can also produce it in small amounts from an amino acid called tryptophan, found in animal protein sources.

Niacin is involved in various important functions, including:

• Normal energy production and metabolism
• Supporting the normal functioning of the nervous system
• Maintaining normal psychological function
• Keeping the mucous membranes in normal condition
• Promoting the health of the skin
• Reducing tiredness and fatigue
  
  

Several studies have been conducted to explore the effects of niacin, such as its potential influence on high blood pressure and cholesterol levels. 

Symptoms of Niacin Deficiency

Niacin deficiency is rare in developed countries because it is well-absorbed from most foods and added to many food products.

It’s important to ensure an adequate niacin intake, especially when certain factors are present.

Factors that can contribute to low levels of B3 vitamin include:

• A diet low in tryptophan or a condition that reduces the body’s ability to convert tryptophan into niacin
• Malnutrition due to conditions like alcoholism, anorexia, or inflammatory bowel disease
• Low intake of B2, B6 vitamins, or iron, as this can reduce the amount of tryptophan converted into niacin
  
  

If you’re concerned about your niacin levels, it’s best to consult with a healthcare professional. To support your dietary needs, you can also consider incorporating dietary supplements into your routine.
