How are Nährstoffcheck and Haut related?

MyBody-X's Nährstoffcheck (nutrient check) analyzes genetic variants related to the metabolism of nutrients such as vitamins, minerals, and fatty acids. Skin health is influenced by these nutrients – for example, vitamin C for collagen synthesis, zinc for wound healing, or omega-3 fatty acids for inflammation regulation. In theory, a nutrient test could reveal individual needs that affect skin condition. However, the evidence for a direct, clinically meaningful link is weak: the effect sizes of the tested SNPs are small, studies are mostly observational, and skin issues are multifactorial (genetics, environment, lifestyle, microbiome). The claimed connection between the Nährstoffcheck and skin health is not supported by specific studies in the provided context. It appears to be a marketing narrative based on plausible but unproven mechanisms. These consumer tests are not validated for medical diagnosis and should not guide skin treatments. Therefore, the relationship is speculative and marketing-driven.
