Which symptoms are associated with Vitamin B3 deficiency?

The symptoms associated with Vitamin B3 (niacin) deficiency are indeed dermatitis, diarrhea, and dementia, which are key components of a condition known as Pellagra. Pellagra is characterized by the "three D's" of symptoms: dermatitis, diarrhea, and dementia. Dermatitis typically manifests as a scaly, dark rash, particularly in sun-exposed areas of the skin. Diarrhea can be severe and impact the digestive system significantly. Dementia refers to cognitive decline and can encompass a range of neurological symptoms.

While the other options contain terms that may relate to various health conditions or deficiencies, they do not accurately capture the classic symptoms of Vitamin B3 deficiency. Glossitis and bloating, for example, are not typically highlighted in the context of niacin deficiency, while anemia and depression relate more closely to other nutritional deficiencies, such as iron or vitamin B12 deficiencies. Thus, the choice that best summarizes the symptoms of Vitamin B3 deficiency is the one listing dermatitis, diarrhea, and dementia.
