What to watch with Nährstoffcheck and Haut?

Combining a nutrient check with skin concerns is reasonable, but the evidence is mixed. A nutrient deficiency test can reveal deficits in vitamin D, zinc, omega-3 fatty acids, or B vitamins, all of which can affect skin health. DNA variants like MTHFR C677T (rs1801133) or PPARA rs4253778 have small effects on nutrient metabolism but are not diagnostic for skin conditions. The gut-skin axis plays an important role: a disrupted microbiome can contribute to acne, eczema, or other skin issues. MyBody-X offers both nutrient and microbiome tests, but results should be seen as clues, not medical diagnoses. Marketing often overstates the direct link between single SNPs and skin outcomes. Practically, a nutrient check can help identify deficiencies that may be corrected with supplements, but persistent skin problems require medical evaluation. The evidence for personalized recommendations from DNA tests for skin improvement is weak to moderate. Be cautious of exaggerated claims and interpret results in the context of lifestyle, diet, and clinical examination.
