What vitamin is associated with Pellagra?

Question

BlackTom AI · Accepted Answer

Pellagra is a nutritional condition historically linked to a deficiency in a B-complex vitamin that plays a key role in energy metabolism.
In clinical context, pellagra presents with the classic three Cs: dermatitis, diarrhea, and dementia, reflecting widespread impacts of niacin deficiency on skin, gut, and nervous system.
The vitamin involved is niacin, also known as vitamin B3, which participates in coenzyme forms (NAD and NADP) essential for redox reactions and cellular energy production.
Deficiency can arise from very low dietary intake, malabsorption, or conditions that impair tryptophan utilization to synthesize niacin (such as Hartnup disease) or increase niacin requirements.
Treatment typically focuses on replenishing niacin (nicotinic acid or nicotinamide) and addressing any contributing factors like poor diet or malabsorption, with example strategies including dietary modifications and supplementation.
Note on the options: this item’s answer choices are not provided here, so a direct option-by-option critique isn’t possible. Nevertheless, understanding that pellagra is tied to niacin deficiency helps explain why Niacin (B3) is the vitamin associated with Pellagra, given its central role in the metabolic pathways implicated in the condition.
