What is Niacinamide?

Niacinamide is vitamin B3 with a slight variation. In other words, it is a form of this vitamin. It is an essential nutrient for various processes in the human body. These include some related to brain function and the nervous system, among others.

  • Antibiotics.
  • Antioxidant. 

All of these properties are directly related to how the body uses Niacinamide. This enters the bloodstream, from there, it is carried to the tissues. When a chemical process begins, it results in the coenzymes nicotinamide adenine dinucleotide and the one containing phosphate.

Thanks to these enzymes, the body performs the inflammation and restoration of tissues to act as a protective wall of the skin against UV rays. It also activates the sebum-suppressing effect, preventing the skin from producing too much oil. And, speaking of its antioxidant capacity, it eliminates the stress that causes said oxidation.

Health benefits of Niacinamide
