Generally, elevated triglycerides are a known risk factor for cardiovascular disease, which can indirectly affect lifespan. However, the evidence for a direct causal role of triglycerides on longevity is moderate and largely based on epidemiological studies. Genetic variants like those in FADS1 can influence triglyceride concentrations, but effect sizes are small and modifiable by lifestyle factors (diet, exercise). MyBody-X tests can identify such variants, but the clinical relevance for individual longevity remains unclear. Without specific longitudinal data or intervention trials, the predictive power is limited. Therefore, the evidence from the given context is rated as 'unclear'.

Some biomarkers like vitamin D, omega-3 index, homocysteine, or magnesium show associations with healthy aging in observational studies. However, for most direct-to-consumer nutrient tests, randomized controlled trials proving a causal benefit for lifespan extension are lacking. Genetic tests (e.g., FADS1 for omega-3 conversion) provide mechanistic hints, but effect sizes are small and often not directly actionable. A blood test measuring actual nutrient levels is usually more informative than a DNA-only check. Moreover, high doses of certain nutrients (e.g., vitamin A, selenium) can be harmful. For an evidence-based longevity strategy, I recommend focusing on established biomarkers (vitamin D, B12, omega-3), individual risk factors (e.g., FTO for obesity), and above all lifestyle factors (diet, exercise, sleep).
