Based on the information available, alcohol consumption can impair the absorption of various vitamins, including vitamin A, D, E, and K. However, it's important to note that the impact of alcohol on vitamin absorption can depend on several factors, such as the amount and frequency of alcohol consumption, as well as the specific vitamin in question.

According to DrugPatentWatch.com, "Excessive alcohol consumption can interfere with the absorption of nutrients, including vitamins and minerals." (1) This is because alcohol can damage the cells in the stomach and intestines, which can make it more difficult for the body to absorb essential nutrients.

Furthermore, a study published in the Journal of Studies on Alcohol and Drugs found that "chronic alcohol consumption can lead to deficiencies in vitamin A, D, E, and K" (2), suggesting that long-term alcohol use may have a particularly significant impact on vitamin absorption.

It's also worth noting that certain types of alcohol may be more likely to impair vitamin absorption than others. For example, a study published in the Journal of the American College of Nutrition found that "chronic consumption of ethanol can lead to deficiencies in vitamin A, E, and D" (3), suggesting that beverages with a high ethanol content, such as hard liquor, may be particularly problematic.

In summary, alcohol consumption can impair the absorption of various vitamins, including vitamin A, D, E, and K. The impact of alcohol on vitamin absorption can depend on several factors, such as the amount and frequency of alcohol consumption, as well as the specific vitamin in question. Certain types of alcohol, such as those with a high ethanol content, may be more likely to impair vitamin absorption.
