A landmark 2024 study published in *Nature Medicine* revealed that excess niacin can produce a harmful metabolite linked to increased cardiovascular risk. While this essential B vitamin is vital for health, high therapeutic doses can lead to significant side effects and potential harm.

While often viewed as completely safe due to their water-soluble nature, excessive intake from supplements can indeed cause harm. The body simply excretes what it doesn't need when consuming a balanced diet, but large supplement dosages can overwhelm this system. For this reason, the question, 'can excess B vitamins be harmful?', has serious implications for your health and requires careful consideration.

Over 21% of adults in the United States report taking a dietary supplement containing niacin.

Up to 80% of individuals taking high doses of immediate-release nicotinic acid experience a "niacin flush," a temporary, uncomfortable side effect that causes redness and warmth. The key question remains, however: are there any benefits to a niacin flush itself, or is it merely an indicator of the underlying vitamin's therapeutic effects?

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 the NIH, the Tolerable Upper Intake Level (UL) for niacin from dietary supplements is 35 mg for adults, yet many high-dose supplements contain far more. This discrepancy is why understanding how do you know if you have too much niacin is crucial for preventing negative health outcomes.
