What it does: It is essential for turning carbohydrates, fats, and proteins into cellular energy and supports DNA repair, healthy nerve signaling, and the resilience of the skin barrier.
How it is used: Niacinamide is most often used to support overall energy metabolism, nervous system health, and healthy skin appearance, and can also be applied in topical skincare for skin barrier support.
Natural sources and supplement forms: Naturally present in poultry, fish, eggs, legumes, seeds, nuts, and whole grains; supplement forms include capsules, tablets, powders, and topical serums or creams.
Why it appears in supplement formulas: Brands use niacinamide because it supports energy production, skin health, and nerve wellness, and does not cause the flushing that occurs with high-dose niacin.
What to know before use: Niacinamide is well tolerated, but very high supplemental doses may cause mild digestive upset; those with liver concerns or using long-term high doses should consult a healthcare provider.
Interesting Fact
Niacinamide: A Versatile Form of Vitamin B3 Found in Everyday Foods
Niacinamide is a form of vitamin B3 that your body can make from tryptophan, an amino acid found in foods like turkey and eggs. Unlike some B vitamins, niacinamide is gentle on the stomach and does not cause the flushing effect often linked to other forms of vitamin B3, making it a popular choice in supplements.
