12 Best Thorne Health Alternatives & Competitors (2026)

Viome provides full-body microbiome testing via stool and oral samples with AI-generated food and supplement advice. Its oral module is less granular than Bristle on cavity- and gum-specific species and pricing starts higher at roughly $299 per kit. Users seeking only oral health insights often find Bristle's focused report and dentist-approved action plan more direct and affordable.

LetsGetChecked delivers at-home hormone, fertility, and thyroid tests with fast lab processing. It includes app-based tracking and nurse support options. Relative to adyn it often emphasizes privacy and international shipping while maintaining similar subscription testing cadence for ongoing monitoring.

Everlywell provides a wide range of at-home test kits for food sensitivity, hormones, and thyroid with physician-reviewed results and app-based tracking. It offers broader consumer accessibility than SiPhox Health but typically lacks the integrated personalized action plan and explicit focus on repeated cardiometabolic trend monitoring. Pricing is per-kit without a membership model, suiting occasional users rather than ongoing optimization.

InsideTracker combines blood biomarker analysis with DNA and lifestyle data to generate nutrition and exercise recommendations aimed at performance and longevity. Unlike SiPhox Health's straightforward at-home finger-prick and action plan, it often requires a blood draw and emphasizes algorithmic optimization for athletes, at a higher price point with subscription elements.

Labcorp OnDemand provides direct access to tests for wellness, allergy, and heart health via local collection sites. Its model contrasts with SiPhox Health by requiring in-person visits and offering no built-in trend tracking or action plans, fitting users who prefer established lab infrastructure over home testing.

Modern Fertility focuses on ovarian reserve and hormone testing aimed at reproductive planning. It provides detailed reports and community resources. Versus adyn it targets a narrower fertility audience with potentially lower per-test costs and educational emphasis rather than full wellness tracking.

OralDNA offers clinician-ordered saliva tests that detect periodontal pathogens. It requires a dental provider visit and does not ship direct-to-consumer kits like Bristle. Results are clinical but lack the consumer-friendly custom probiotic and diet plans Bristle supplies at a lower out-of-pocket cost.

Quest Direct allows consumers to order lab tests online for pickup at local centers, covering lipids, hormones, and vitamins. It lacks SiPhox Health's at-home convenience and personalized action plans, instead providing raw results suited for those already comfortable with standard lab workflows and follow-up care.

Function Health runs comprehensive blood panels with hormone markers and longitudinal tracking. It provides physician-reviewed insights via an app. In comparison to adyn it covers more biomarkers overall and positions itself for proactive health optimization at a higher annual commitment.
