Thorne

Founded in 1984 by Al Czap, Thorne began in Seattle as a mission-driven company dedicated to elevating nutritional supplements through purity, science, and clinical-grade formulation.

Today, from its NSF- and TGA-certified facility in Summerville, South Carolina, Thorne formulates and produces all its supplements under high manufacturing standards.

Thorne offers a range of supplements, including their NSF-Certified Basic Nutrients 2/Day multivitamin with easily absorbable vitamins (A, B complex, C, D₃, E, K₁/K₂) and zinc. They also have products for athletic performance, immune support, metabolism, and cognitive function.

The company has also expanded into home health testing and practitioner-guided solutions, driving innovation through joint research with clinical partners.

VitaRx

VitaRx, founded in 2019 by Jesse Villanueva, is a Puerto Rico–based personalized vitamin brand born from his personal experience with malnutrition and the frustration of navigating supplement choice alone.

Motivated by this, he created a smart health quiz to create personalized daily vitamin packs delivered to you via convenient monthly subscription.

VitaRx prides itself on transparency, quality, affordability, and innovation.

It sources responsibly tested, cGMP- and FDA-manufactured ingredients, including organic-certified options, with full labeling and rigorous third-party lab testing to ensure purity, potency, and safety.

VitaRx champions health and wellness by prioritizing accessibility, innovation, and quality, making personalized health sustainable and accessible to everyone.

In-depth comparison

Personalization approach

Thorne’s personalization process is rooted in its practitioner-first model, offering individualized supplement guidance through healthcare providers who leverage the brand’s extensive catalog and at-home health tests.

These diagnostics—covering gut health, stress response, and nutrient status—analyze key biomarkers to inform clinically grounded recommendations.

Supported by partnerships with institutions like the Mayo Clinic and decades of clinical collaboration, Thorne delivers targeted regimens that integrate medical oversight with advanced formulation science.

VitaRx delivers a streamlined, customer-friendly personalization experience built around a three-minute online health quiz.

Users share lifestyle details, dietary habits, and wellness goals, which are then processed by a smart algorithm to generate tailored supplement blends.

These blends focus on evidence-backed essentials, ensuring recommendations are both effective and easy to follow.

Delivered in daily dispenser packs, VitaRx’s approach eliminates guesswork, making personalized nutrition simple, affordable, and accessible.

Ease of use

Thorne’s begins with a detailed health profile, often supported by at-home tests that assess biomarkers like nutrient status and stress response.

These results, combined with lifestyle information, are reviewed through its Onegevity Health Intelligence platform, resulting in a personalized supplement plan.

While thorough, the process can require professional guidance, making it best suited for people comfortable with a more involved, medically guided approach.

VitaRx starts with a brief health quiz that collects lifestyle, dietary, and wellness goal information to generate a personalized supplement plan.

Recommendations are delivered in convenient daily dispenser packs, and users can easily adjust or cancel subscriptions online.

This self-service, fast-start process makes onboarding simple, accessible, and ideal for customers who want immediate, low-effort personalization.

Pricing & value

Thorne positions itself as a premium supplement provider, with flagship products like Basic Nutrients 2/Day costing $38 per month.

This higher price point reflects its use of rigorous manufacturing standards, but it may be less accessible for budget-conscious consumers.

VitaRx starts at an affordable monthly rate, with plans under $30, while still offering clinically informed, third-party tested supplements.

Its flexible pricing depends on the number and type of nutrients selected, making it possible to tailor a plan to both health goals and budget.

This value-oriented approach appeals to people who want a balance between affordability, quality, and transparency.

Transparency & testing

Thorne maintains strict quality control through in-house evaluations and independent third-party verification, manufacturing in FDA-registered, cGMP-compliant facilities.

Many products carry certifications like NSF and Australia’s Therapeutic Goods Administration approval, among the most rigorous in the world.

While known for clean formulations and ingredient transparency, not all products are accompanied by publicly available Certificates of Analysis, limiting full consumer verification.

VitaRx takes a transparency-first approach, testing both raw ingredients and finished products in FDA-regulated, cGMP-certified facilities, with many offerings also QAI-certified organic under USDA standards.

The brand provides detailed third-party testing, verifying purity, potency, and the absence of contaminants.

Third-party certifications like NSF, USP, and Informed-Sport help ensure that supplements deliver exactly what the label claims, free of harmful contaminants, and safe for everyday consumers and athletes alike.
