Yes, alcohol consumption can decrease magnesium levels in the body. Magnesium is a vital nutrient that plays a crucial role in various bodily functions, including muscle contraction, nerve function, and blood pressure regulation [1].

Excessive alcohol consumption can interfere with the body's ability to absorb magnesium, leading to magnesium deficiency [2]. Alcohol can also increase urinary excretion of magnesium, further depleting the body's magnesium levels [3].

Moreover, chronic alcohol consumption can lead to alcoholic magnesium-deficient syndrome, a condition characterized by low magnesium levels, neuromuscular symptoms, and cardiac arrhythmias [4].

It is essential to maintain adequate magnesium levels in the body, and individuals who consume alcohol excessively may need to take magnesium supplements to prevent magnesium deficiency [5]. However, it is always recommended to consult a healthcare professional before starting any supplement regimen.

In summary, alcohol consumption can decrease magnesium levels in the body, leading to magnesium deficiency and various health complications.
