What to watch with Longevity DNA Test and stress?

When using a Longevity DNA Test in the context of stress, focus on genes like COMT, BDNF, and FKBP5, which are linked to stress response and resilience. However, the evidence is primarily mechanistic or from GWAS – not from human intervention trials. A genetic variant does not determine your actual stress level; it only offers a weak probabilistic hint. More actionable are blood biomarkers such as cortisol (saliva or serum), inflammatory markers (CRP, IL-6), and subjective stress scales. The DNA test can complement but not replace clinical assessment. Be cautious of marketing claims that overstate the predictive power of these SNPs. For example, the COMT Val158Met variant has small effect sizes and interacts with environment. Do not start high-dose supplements (e.g., ashwagandha, magnesium) based solely on genotype without professional guidance. Evidence rating: mixed (mechanistic + some GWAS). Sources: none from provided context. Practical advice: combine DNA insights with regular biomarker testing and lifestyle tracking.
