Niacin is a B-vitamin that plays an essential role in energy production and maintaining healthy skin, nerves, and digestion. It is found in many foods, including meat, fish, and grains. Alcohol consumption can interfere with the body's ability to absorb and utilize niacin [2]. According to the National Institutes of Health (NIH), heavy alcohol intake can cause niacin deficiency [3].

The drugpatentwatch.com website provides information about the alcohol industry and its patent expirations. It does not provide any information about the relationship between alcohol intake and niacin absorption.

The National Center for Biotechnology Information (NCBI) book chapter explains that alcohol consumption can interfere with the body's ability to absorb niacin by reducing the absorption rate in the small intestine [2]. Chronic alcohol use can also lead to a reduction in niacin storage in the liver, which can cause niacin deficiency [2]. The book chapter suggests that people who consume alcohol should increase their niacin intake to avoid deficiency.

The NIH fact sheet on niacin explains that the recommended dietary allowance (RDA) for niacin varies depending on age and gender. The RDA for adult men is 16 milligrams (mg) per day, and for adult women, it is 14 mg per day [3]. The fact sheet also notes that niacin is available in supplement form but warns against taking high doses of niacin supplements without medical supervision [3].

In conclusion, alcohol consumption can interfere with the body's ability to absorb and utilize niacin, potentially leading to niacin deficiency. However, increasing niacin intake through food or supplements can help mitigate this risk. It is important to consult a healthcare professional before taking niacin supplements, especially at high doses.
