Vitamin B3 & Dermatitis

Benefits

Vitamin B3 (also known as niacin) is also extremely important in energy production and is essential for converting dietary fats, proteins and carbohydrates into energy as well as providing antioxidant protection. As well as being essential for energy production (and feeling good), vitamin B3 is needed for DNA repair.

Niacin is also known to boost the function of the skin and has shown in clinical studies to protect skin cells from sun damage (Chen, 2015).

Symptoms of deficiency can include fatigue, rough skin, indigestion and dermatitis, which is similar to eczema but presents without the itch.

Pellagra is a disease which can occur from chronic vitamin B3 deficiency. The symptoms of pellagra are know as the ‘three Ds’: dermatitis, diarrhoea and dementia. Some researchers call it the ‘four Ds’ and include ‘death’, as death eventually results if the deficiency is left untreated and becomes chronic.

Important notes about B-group vitamins

When taking any kind of B vitamins keep the following nutrition rules in mind:

  • As B-group vitamins are acidic, avoid mega-doses above 15 mg. In order to prevent deficiencies of other B vitamins, take vitamin B3 in supplement form along with other B vitamins, not as a single supplement.

Niacin flush

Taking high doses of vitamin B3 will cause a ‘niacin flush’ where the skin becomes hot and red. So if you have topical steroid withdrawal (red skin syndrome), eczema or rosacea do not take a high dose of vitamin B3 (above 10mg) as it can worsen your symptoms. For this reason, Skin Friend AM contains only a low dose of vitamin B3.
