Niacinamide pills are a form of vitamin B3 that support both skin and overall health. They help reduce acne, redness, and dark spots while strengthening the skin barrier and improving moisture retention. Niacinamide also boosts collagen, helping to smooth fine lines and even skin tone. Beyond beauty, it aids in converting food into energy, supports healthy brain and nerve function, and helps repair DNA damage. It’s often used to calm inflammation, promote healthy aging, and maintain overall cell health — without causing the flushing that comes with regular niacin.
