MyBody-X angle on Cortisol Basis

MyBody-X's angle on the Cortisol Basis likely involves genetic variants in the NR3C1 gene (glucocorticoid receptor). The available evidence (human-moderate) indicates that common SNPs in NR3C1 have only very small effects on cortisol regulation and cannot diagnose high cortisol levels or stress disorders. Rare mutations can cause glucocorticoid resistance, but these are not covered by standard DNA tests. Therefore, MyBody-X DNA tests do not provide clinically actionable information about your actual cortisol levels. Reliable assessment requires blood or saliva tests that measure the diurnal cortisol rhythm. The evidence for personalized stress or dietary advice based solely on NR3C1 SNPs is weak. MyBody-X should clearly communicate this limitation and avoid implying that a DNA test can diagnose cortisol imbalances. Safety note: If you suspect cortisol dysregulation (e.g., fatigue, weight gain, high blood pressure), consult a doctor for endocrine evaluation. The genetic information may serve as background knowledge but does not replace medical diagnostics.
