Can ADH1B help with Müdigkeit?

Whether ADH1B can help with fatigue lacks direct scientific evidence. ADH1B encodes an alcohol dehydrogenase enzyme. Certain variants (e.g., ADH1B*2) accelerate ethanol breakdown to acetaldehyde. After alcohol intake, this may lower blood alcohol but also increase acetaldehyde, which can cause flushing, headache, and fatigue. Thus, any link to fatigue is indirect and only relevant in the context of alcohol consumption. Without alcohol, ADH1B has no known direct effect on general tiredness. The evidence is mechanistic; no robust human studies connect ADH1B variants to fatigue outside alcohol metabolism. MyBody-X DNA tests are wellness tools, not medical devices. Chronic fatigue should be evaluated by a physician for common causes (iron deficiency, thyroid, sleep disorders). A single ADH1B variant is not a meaningful factor.
