Can ADH1B help with fatigue?

Whether ADH1B can help with fatigue is not supported by direct evidence. ADH1B encodes alcohol dehydrogenase, an enzyme that breaks down ethanol. Certain variants (e.g., ADH1B*2) accelerate alcohol metabolism and are linked to lower alcohol intake, which might indirectly improve sleep and energy levels. However, no clinical studies demonstrate that ADH1B genotyping directly reduces fatigue. The evidence is mechanistic and based on population associations, not interventional trials. Fatigue has many causes—iron deficiency, thyroid dysfunction, sleep disorders, stress, or depression—that should be evaluated by a healthcare professional. A single-gene test like ADH1B is not a diagnostic or therapeutic tool for exhaustion. MyBody-X tests do not provide validated claims for this use. Be cautious of marketing that overstates genetic influence on complex traits like energy levels.
