According to the National Institutes of Health, the tolerable upper intake level (UL) for niacinamide from supplements is 900 mg per day for adults, based on data regarding potential gastrointestinal effects. A daily oral dose of 2000 mg of niacinamide, therefore, significantly exceeds this safety threshold and is considered too much for most individuals.

According to dermatologists at the Cleveland Clinic, most people can safely use topical niacinamide at a concentration of 5% or less. Understanding how much niacinamide is too much daily is crucial for both skincare enthusiasts and those taking oral supplements to prevent potential irritation and adverse health effects.

According to a randomized controlled trial, taking oral niacinamide may significantly reduce the risk of new non-melanoma skin cancers in high-risk individuals. The comprehensive benefits of taking niacinamide orally extend beyond just skin health, supporting vital functions throughout the body and improving overall wellness.

According to research, oral niacinamide is considered likely safe when used appropriately and is distinct from topical skincare products. This vital form of vitamin B3 is available in dietary supplements and certain foods, but its consumption requires careful attention to dosage and form to avoid adverse effects.
