What is the most common vitamin deficiency found in alcoholics?

In alcoholics, the most common vitamin deficiency is folate. Chronic alcohol consumption interferes with the absorption and metabolism of various nutrients, and folate deficiency is particularly prominent due to a combination of nutritional inadequacies and impaired absorption.

Alcoholics often have poor dietary intake, which contributes to folate deficiency, as folate is largely obtained from fruits and vegetables, which may be neglected in an alcoholic diet. Additionally, alcohol can impair the liver's ability to store and metabolize folate. Furthermore, chronic alcohol consumption can result in the development of gastrointestinal issues that further hinder nutrient absorption.

Folate plays a critical role in DNA synthesis and repair, and its deficiency can lead to macrocytic anemia and neurological complications, among other health issues. This makes it especially significant in the context of alcohol use disorder, as the ensuing health problems can compound the physiological effects of alcohol.

Understanding the impact of alcohol on nutritional status highlights the importance of appropriate dietary management and supplementation in individuals with alcohol use disorder, underscoring the role of healthcare providers in identifying and addressing such deficiencies.
