Composition ID

What Composition ID does

Composition ID is a private nutrition coaching and clinical body-composition testing company founded in 2014 and headquartered in Washington DC. The company delivers services based on DEXA (Dual-Energy X-Ray Absorptiometry) scanning — the diagnostic gold standard for body composition analysis — supplemented by Resting Metabolic Rate (RMR) testing using KORR medical-grade metabolic equipment, VO2 Max graded exercise testing, blood chemistry analysis, and 3-month personalized Nutrition Coaching programs. Its reporting capabilities include body fat, lean mass, bone mineral content, visceral adipose tissue, and regional balance across five body regions (arms, legs, trunk, android belly, gynoid hips).

The company operates a hybrid distribution model consisting of six owned physical studios — three in the Washington DC metro (Washington DC, College Park, Tysons Corner/McLean) plus Houston TX, Scottsdale AZ, and Orlando FL — and a mobile Scan Van that brings testing to universities, sports teams, gyms, and corporations across the DC/MD/VA region. Pricing for an initial DEXA scan starts at $150 with bundle discounts available; Nutrition Coaching is structured as a 3-month personalized program priced separately. The customer base spans individual consumers (mid-market), professional sports franchises (Washington Capitals, Wizards, Mystics), collegiate programs (University of Maryland), and commercial fitness partners (Orangetheory Fitness), as well as corporate wellness buyers reached via the Scan Van. Composition ID is female-founded (Tiffany Harlan serves as Founder, CEO, and Director of Finance and Operations) and operates without disclosed external funding, making it a bootstrapped, founder-controlled multi-location services business.

Expansion highlights5 records

Emerging players

• Whoop: Wearable subscription service delivering recovery, strain, and (recently) body composition and VO2 Max estimates. Competes for the data-driven fitness audience that Composition ID serves through DEXA and VO2 Max testing.
• Levels Health: Continuous glucose monitoring and metabolic health platform that delivers real-time metabolic data. Adjacent to Composition ID's RMR and blood chemistry offerings through a different (wearable) modality targeting the same health-conscious consumer.
• Metabolic Mentor: Specialized RMR and metabolic testing services often paired with nutrition coaching. Comparable offering on the metabolic diagnostics + coaching intersection, smaller scale and likely regionally focused.

Broad incumbents

• WW (Weight Watchers): Established weight management program with a coaching/nutrition curriculum at national scale. Comparable customer outcome (weight loss) but competes through a digitally delivered program rather than in-person diagnostics.
• Noom: Large-scale weight management and behavior-change platform with a coaching-led model. Differs on delivery (app-first) but addresses overlapping customer demand for structured, coaching-supported weight and metabolic health outcomes.

Others

• Orangetheory Fitness: Existing Composition ID customer/partner and a national fitness franchise. Not a direct competitor but represents the type of large-scale fitness brand that could anchor enterprise Scan Van contracts and partnerships.

Direct peers

• DexaFit: Operates DEXA, RMR, and VO2 Max testing centers across multiple US cities with a similar science-driven, testing-first model targeting athletes and fitness-focused consumers. Closest direct competitor in core service offering and customer profile.
• BodySpec: DEXA-focused body composition scanning service with mobile/pop-up locations and permanent studios serving athletes and fitness consumers. Direct competitor on DEXA as the lead product with comparable pricing and positioning.
• Stronger U: Nutrition coaching service pairing clients with registered dietitians and supporting accountability via tracking. Comparable on the personalized nutrition coaching layer that complements Composition ID's testing services.
• Fitnescity: Aggregates DEXA, VO2 Max, RMR, and other fitness testing services across multiple cities. Competes on the same core diagnostic services but as a booking platform rather than owned-operator.
