Vitamin B3

Why Does a Vitamin B3 Deficiency Occur?

Vitamin B3 deficiency, also known as pellagra, occurs due to inadequate intake or absorption of niacin or tryptophan. This can result from poor diet, alcoholism, gastrointestinal diseases, or conditions that impair nutrient absorption, such as Crohn's disease or celiac disease. In some cases, genetic disorders like Hartnup disease can hinder the body's ability to convert tryptophan to niacin.

Prolonged use of certain medications, like isoniazid for tuberculosis, can interfere with niacin metabolism. Socioeconomic factors and limited access to a varied diet also contribute to the prevalence of niacin deficiency in certain populations.

What to Do About Vitamin B3 Deficiency?

Vitamin B3 deficiency, it is essential to improve dietary intake through foods rich in niacin, such as meat, fish, poultry, whole grains, nuts, and legumes. In cases of severe deficiency, niacin supplement is required. 

Managing underlying conditions that affect nutrient absorption, like gastrointestinal diseases, is crucial. Reducing alcohol consumption can also help improve nutrient absorption.
