    Everything you need to know

    This collaboration combines Biostarks’ laboratory-grade biomarker testing with Solgar’s gold-standard supplements. You measure your biomarkers, review your personal biomarker report and health recommendations with your healthcare provider, and choose supplements that are right for you.

    Biostarks shows you your actual biomarker levels, and then provides recommendations, so you can tailor your supplement routine to what your body may need.

    Yes. Even with a balanced diet and supplements, absorption, training load, stress, and lifestyle can affect your internal levels. This test helps verify what’s working—and what may still need adjustment.

    Depending on the panel, we analyze key micronutrients, fatty acids, hormones, and metabolic markers that influence energy, recovery, immunity, longevity, and overall health.

    You collect a small sample at home in under 5 minutes and return it using the prepaid envelope. Once received, your sample is analyzed and your results are securely delivered online.

    Most users receive their results within 5–10 days after the lab receives the sample.

    Absolutely. Many users retest every few months to see how nutrition and supplementation impact their biomarkers over time.

    Anyone who wants clarity—whether you’re focused on daily wellness, sport performance, longevity, or metabolic health. If you value understanding your potential health needs, this is for you.

    Yes. Test kits can be purchased using FSA/HSA funds where applicable. Refer to your FSA/HSA plan documents for confirmation
