Evidence check: DNA Stoffwechseltest in the context of menopause

A DNA metabolism test (e.g., from MyBody-X) analyzes genetic variants in genes like MTHFR, ALDH2, or TAS2R38 that may influence nutrient processing. In the context of menopause – a period of hormonal shifts, altered energy metabolism, and increased risk for weight gain, insulin resistance, and cardiovascular issues – such tests promise personalized dietary advice. However, the evidence is weak: no randomized controlled trials demonstrate that DNA-based nutrition during menopause yields clinically meaningful benefits (e.g., weight loss, improved lipid profiles, or reduced hot flashes). Most data come from observational studies or mechanistic links. For instance, an MTHFR variant can affect homocysteine levels, but routine methylfolate supplementation is not universally recommended. Similarly, ALDH2 variants influence alcohol metabolism but are not menopause-specific. The test may serve as an informational tool but should not drive treatment decisions alone. Clinical parameters (blood work, symptoms) and medical supervision remain essential. Evidence grade: marketing/unclear.
