Tag: Excess niacin

According to the National Health and Nutrition Examination Surveys, average daily niacin intake from food and beverages for American adults is 31.4 mg for men and 21.3 mg for women, with most people consuming more than the Recommended Dietary Allowance. While toxicity from dietary niacin is rare, excessive intake from supplements can lead to a range of mild to severe side effects and health complications.

According to recent research, excess niacin intake can lead to elevated levels of a specific metabolite (4PY) that is associated with an increased risk of heart attack and stroke. Understanding what high B3 means is critical, as it's typically caused by supplements rather than food and can have serious health implications.

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.
