According to the Cleveland Clinic, severe niacin deficiency, known as pellagra, is rare in developed countries but still affects certain populations. Anyone whose diet lacks sufficient niacin or tryptophan is at risk, as are individuals with underlying health issues that interfere with nutrient absorption or utilization. Understanding who is at risk for niacin deficiency can be crucial for prevention and early detection.

Niacin, or Vitamin B3, has a surprisingly short half-life of just 20 to 45 minutes for its immediate-release form. Understanding exactly **how long does niacin stay in your body?** is key for managing its effects, whether for supplementation or therapeutic use.

Excess vitamin B3, also known as niacin, is typically excreted by the body in urine because it is water-soluble. While the body does not store large amounts, high supplemental doses can overwhelm this excretion process, leading to various side effects and potentially serious health complications.
