Health Benefits Of Vitamin B3 For Skin And Body?

The beauty and health of the skin are related to maintaining the level of vitamins in the body. One of these vitamins is vitamin B3. Let’s discuss the health benefits of vitamin B3 or niacin for the skin.

What is Niacin (Vitamin B3)

Vitamin B3, or niacin, is one of the eight types of B vitamins. It is a water-soluble vitamin that is not stored in the body, but the surplus amount of vitamin B3 is excreted from the body. Therefore, you must eat the necessary quantities of it constantly. (1)

Vitamin B3 is an essential nutrient for the body, as it turns food into energy.

In this article, we will discuss the health benefits of niacin or vitamin B3 for the skin.

Health benefits of niacin (vitamin B3) for skin

The health benefits of vitamin B3 for the skin lie in maintaining healthy skin by increasing protein production and maintaining skin hydration by stimulating the production of ceramide, which is a lipid barrier that protects the skin from drying out, which helps in improving the eczema problem. (2, 3, 4)

The benefits of vitamin B3 also include reducing skin inflammation, which helps reduce the redness caused by some inflammatory skin problems such as acne irritation and eczema, and there is also a possibility to reduce pigmentation. (5)

Vitamin B3 helps reduce fine lines and wrinkles in the complexion and improves the surface of the skin. (6)

In addition to the health benefits of vitamin B3 above, a study has shown the effectiveness of niacin in protecting the skin from UV damage and reducing the incidence of skin cancer and actinic keratoses.

Other health benefits of niacin

Vitamin B3 is used to control the level of cholesterol in the body by helping to boost the level of good cholesterol (HDL) in the body and reduce the proportion of bad cholesterol (LDL). (7, 8)

However, there is no scientific evidence linking vitamin B3 to a reduced heart attack risk or death. (9, 10)

Vitamin B3 is used to treat and prevent pellagra, and preliminary results have indicated the potential effectiveness of taking vitamin B3 supplements during pregnancy in avoiding birth defects.

How do I get vitamin B3?

Usually, we can get vitamin B3 through eating a balanced diet, as vitamin B3 is naturally present in many foods such as legumes, nuts, red meat, fish, in addition to chicken. (11)

Vitamin B3 can also be taken as a dietary supplement if a larger dose is needed. That is after consulting a healthcare provider.

Besides, many skin products contain vitamin B3 due to the health benefits of niacin for the skin.
