Effects of 'Essential AD2' Supplement on Blood Acetaldehyde Levels in Individuals Who Have Aldehyde Dehydrogenase (ALDH2) Deficiency

摘要

Background: It is estimated that 1 billion people in the world have a point mutation in the gene encoding the aldehyde dehydrogenase 2 (ALDH2) enzyme, the primary enzyme responsible for the metabolism of acetaldehyde. The presence of this mutation is called ALDH2 deficiency. Because of limited ability to metabolize acetaldehyde, individuals with ALDH2 deficiency experience elevated levels of blood acetaldehyde after exposure to various common sources such as recreational alcohol. Because of higher levels of acetaldehyde, individuals with ALDH2 deficiency are at higher risk for numerous diseases, including liver cirrhosis, esophageal and gastric cancer, osteoporosis, and Alzheimer disease.
