Niacin (Vitamin B3) is an essential nutrient that the human body requires. To function correctly, all parts of your body need nutrients. The medical names for Niacin (vitamin B-3) are Niacinamide, Nicotinic Acid or Inositol Hexanicotinate.

Niacinamide provides energy for the body by turning food into cellular energy. Some of the critical functions performed by Niacin are as follows:

  • It keeps your nervous system healthy, & makes sure it functions properly. 
  • Niacinamide dilates the blood vessels and increases the flow of blood to the peripheral capillaries.
  • It is essential for the production of vital hormones, including estrogen and testosterone. 
  • Helps the digestive system function well and deals with skin-related issues such as pellagra to keep your body healthy.
