Metabolism Test
Everlywell is the most accessible home-testing brand with excellent UI and clear, actionable reports. Their Metabolism Test measures TSH, Cortisol, and Testosterone (in women) or DHEA, providing a solid snapshot of hormonal health that impacts weight and energy.
Ingredients & Purity
The kit includes standard lancets and blood spot collection cards. While effective, blood spots can sometimes be harder for users to saturate correctly compared to liquid microtainers.
Scientific Evidence
Uses CLIA-certified labs. They provide validated ranges for all markers, though finger-prick cortisol is less definitive than a 4-point salivary diurnal rhythm test.
Brand Transparency
Very transparent about their medical advisory board and the labs they use (like Access Medical Laboratories).
Value Assessment
Good value for a basic screening, though more serious athletes or those with chronic issues may find the biomarker list slightly limited.
Why Not Alternatives?
Everlywell's strength is its simplicity and retail availability (Target, CVS), making it better for general wellness screening than the more complex Thorne or LetsGetChecked options. However, they use third-party labs rather than owning their own.
