Which vitamin deficiency is known as Pellagra?

Pellagra is specifically associated with a deficiency in Vitamin B3, also known as niacin. Niacin plays a crucial role in energy metabolism and the proper functioning of the nervous system. When the body lacks sufficient niacin, it can lead to symptoms characterized by the classic triad of dermatitis, diarrhea, and dementia, which are hallmarks of Pellagra.

Additionally, Vitamin B3 is essential for the maintenance of healthy skin and the synthesis of certain hormones, making its presence vital for overall health. While the other vitamins listed are important, none are directly related to Pellagra's specific symptoms or condition. For instance, Vitamin B1 is involved in energy metabolism as well, but its deficiency leads to Beri-Beri. Similarly, Vitamin B12 deficiency can cause neurological issues and anemia, while Vitamin C deficiency is linked to scurvy, characterized by symptoms such as bleeding gums and fatigue. Therefore, the association of Pellagra with Vitamin B3 is well-established in nutritional science.
