Anti-Aging | SKINCARE DNA-Test: what are common causes?

A DNA test for MTHFR variants can inform you about your homocysteine metabolism, but it does not directly predict longevity. These variants are associated with a modest increase in vascular disease risk, not with lifespan extension. Effect sizes are small, and lifestyle factors such as diet, exercise, and smoking have a much larger impact. A blood homocysteine test is more actionable than a genetic test. Do not overinterpret: MTHFR is not a 'longevity gene.' The evidence is based on human observational studies, not interventional trials. A DNA test can identify your genotype, but personalized lifestyle advice based on blood markers and medical evaluation is more valuable. If you have already taken the test, discuss results with a doctor before taking supplements like folic acid or vitamin B12. In summary, MTHFR testing has limited utility for longevity purposes.
