What to watch with TSH and Langlebigkeit?

The question about TSH and longevity is complex. TSH (thyroid-stimulating hormone) is a clinical marker of thyroid function, not a direct longevity gene. Some observational research suggests a U-shaped relationship: moderately elevated TSH in older adults may be associated with longer lifespan, but evidence is conflicting and not causal. Consumer DNA tests (e.g., MyBody-X Longevity Test) cannot measure TSH levels; they only analyze small-effect SNPs related to thyroid regulation. The clinical utility for longevity is unclear. For personalized health optimization, measure TSH via blood test and discuss with a physician. Avoid marketing claims that link TSH directly to anti-aging without robust evidence.
