Vitamin B3 is also known as ?

Vitamin B3, commonly known as Niacin, is one of the important B-complex vitamins required for maintaining overall health. It plays a vital role in cellular metabolism, particularly in converting carbohydrates, fats, and proteins into usable energy. Niacin helps the body form NAD (Nicotinamide Adenine Dinucleotide) and NADP (Nicotinamide Adenine Dinucleotide Phosphate) — two coenzymes that are essential for energy transfer in cells.

Niacin also supports healthy skin, nervous system, and digestive system. It improves blood circulation and reduces levels of bad cholesterol (LDL) while increasing good cholesterol (HDL), making it beneficial for heart health. A balanced intake of niacin ensures proper function of enzymes involved in oxidation-reduction reactions in the body.

Let’s review the options for clarity:

• 
  

  A) Thiamine — This is Vitamin B1, which is vital for nerve function and carbohydrate metabolism.

  
  


• 
  

  B) Riboflavin — This is Vitamin B2, responsible for energy production and maintaining healthy eyes and skin.

  
  


• 
  

  C) Niacin — This is the correct answer, as it is another name for Vitamin B3.

  
  


• 
  

  D) Retinol — This is Vitamin A, important for vision and immune system health.

  
  

A deficiency of Vitamin B3 (Niacin) causes Pellagra, a disease characterized by dermatitis, diarrhea, and dementia — often summarized as the “three D’s.” On the other hand, excessive intake of niacin supplements can cause skin flushing or liver issues, which is why balanced consumption through diet is recommended.

Natural food sources of niacin include meat, fish, poultry, peanuts, whole grains, and green vegetables. A well-rounded diet helps prevent vitamin deficiencies and supports overall metabolic health.

✅ Correct Answer: C) Niacin
