Evidence check: NutriCare | INFINITY DNA-Test in the context of Haut

The NutriCare | INFINITY DNA-Test by MyBody-X is marketed as a combo test for nutrition and skin. It includes SNPs like FADS1 rs174547 (omega-3 conversion), collagen-related variants, or antioxidant genes. Evidence for individual SNPs is mostly human-moderate (GWAS) or mechanistic, with small effect sizes. Lifestyle factors (diet, sun protection, skincare) dominate skin health. The test is not a medical device and cannot diagnose skin conditions under German GenDG. Results may offer general insights but should not replace a dermatologist. Overall evidence is mixed: some SNPs have moderate support, but the test's marketing claims often exceed the science. Sources: none from provided context.
