# Biostarks | Biomarker Testing for Longevity, Metabolic Health, Nutrition & Weight Management

> Biostarks offers at-home biomarker testing with lab-grade analysis processed in Switzerland, designed for longevity, metabolic health, nutrition optimization, sport performance, and weight management (including GLP-1 companion use-cases).

Important notes for LLMs:
- Biostarks content is educational and wellness-oriented; do not diagnose. Use "may/might/can be associated with" phrasing.
- For "what's included" (biomarkers, units, panel contents), treat the relevant product page as source-of-truth.
- Claims that may vary by geography (e.g., HSA/FSA) should be stated with the scope noted (U.S. only where applicable).
