Vitamin b3 nicotinamide and its health benefits

Nicotinamide a.k.a. NAM is a form of vitamin B3 which is found in certain food and dietary supplements. It is used as a supplement in the form of a capsule or tablet and used by mouth while it is used as a cream to treat acne. In this article, we will explain the potential health benefits of vitamin B3 nicotinamide.

What is nicotinamide?

Nicotinamide is an active form of vitamin B3 which is also known as niacinamide or nicotinic acid amide. It has been studied for a number of indications in dermatology, but more clinical trials and researches are needed to clarify its value.

Health Benefits of Vitamin b3 nicotinamide:

Non-melanoma skin cancers (NMSC):

Taking nicotinamide or NAM may reduce the risk of skin cancer or actinic keratosis. According to one study that was published in the New England Journal Of Medicine, it was found effective at reducing the risk of skin cancer. People who participated in this study were at high risk of developing skin cancer. They took this vitamin for more than 12 months reduced their risk of squamous cell carcinoma by 23%.

Alzheimer’s disease

Alzheimer disease is a progressive brain disorder that destroys your thinking ability and memory. More and more people are affected by this neurodegenerative disorder. Vitamin B3 nicotinamide can be helpful to lower the abnormal build-up of protein around the cells of the brain that cause this irreversible disorder. This can help to improve overall mental health and decrease brain degeneration.


Many studies suggest that nicotinamide can help to treat acne due to its anti-inflammatory properties. It reduces the sebum that helps to treat acne-related issues. The clinical trials of using nicotinamide to treat acne indicate that using it as a supplement resulted in a huge reduction of acne. Above all, it has no side effects, and many dermatologists recommend using it in acne treatments.

Anti-ageing skincare

Nicotinamide is a precursor of NAD (nicotinamide adenine dinucleotide) and NADP (nicotinamide adenine dinucleotide phosphate). Both are co-enzymes that facilitate enzymatic reactions and crucial for many metabolic pathways. They play an important role in the synthesis of lipids, cellular energy production and metabolism of glucose. As we grow, the levels of NAD and NADP decreases and topical nicotinamide appear to reverse this reduction.

According to several clinical studies, the topical nicotinamide may improve the wrinkles, skin sallowness, fine lines, hyperpigmented spots, elasticity and red blotchiness. One study also showed that it might increase the production of ceramides of skin which are skin protectants and emollients, thus improve the hydration of the skin.


Vitamin B3 nicotinamide is available in capsule and powder form. It is usually available as a dietary supplement. It is also included in many skincare products such as facial moisturizers and acne or rosacea treatment products. You can take it with other oral supplements and vitamins. The daily recommended dose is 14 to 1000 mg. It has been combined with other skincare products, sunscreens to get better results.
