Methodology



Our Approach

At Verus PhytoMed™, product evaluation is grounded in a simple principle:

Formulation should align with the available human clinical evidence.

Not all supplements are created equally. Differences in dosing, ingredient form, standardization, and manufacturing quality can significantly influence how closely a product reflects what has been studied in research.

This page outlines the framework used to evaluate and categorize products featured on this site. This framework reflects a clinician-led approach to evaluating botanical supplements based on available human research, formulation quality, and transparency.

Core Evaluation Criteria

1. Alignment with Clinical Research

Priority is given to formulations that reflect:

  • Ingredient forms used in human studies

  • Dosing ranges consistent with clinical trials

  • Frequency and duration consistent with research protocols

  • Biological plausibility based on known mechanisms

For example, if most studies evaluate a specific form or dose, products that match those parameters are considered more aligned with the evidence base.

2. Ingredient Form and Standardization

Botanical supplements may vary widely in composition.

We evaluate:

  • Whether the active compound is standardized

  • Whether the form used has been studied in human trials

  • Whether extract ratios or concentrations are clearly defined

Products that use well-characterized forms are prioritized for consistency and reproducibility.

3. Manufacturing Quality and Testing

Quality control is an important consideration in supplement selection.

We review whether companies provide:

  • Third-party testing or Certificates of Analysis (COAs)

  • Manufacturing in facilities that follow Good Manufacturing Practices (GMP)

  • Testing for contaminants such as heavy metals or microbial impurities

Transparency in testing and sourcing is considered a positive indicator of product quality. When available, batch-specific testing is considered a stronger indicator of quality control.

4. Label Transparency

Clear labeling supports informed decision-making.

We assess whether products provide:

  • Full disclosure of active ingredients and dosages

  • Clear identification of ingredient forms

  • Absence of proprietary blends that obscure dosing

Transparent labeling allows comparison with clinical research and supports accountability.

5. Safety Considerations

Safety is evaluated based on:

  • Known side effects reported in clinical studies

  • Potential interactions with medications

  • Contraindications identified in the literature

Products are considered within the context of the available safety data.

Product Tier Classification

Products referenced on this site are categorized into tiers based on formulation and quality criteria. Not all products within a tier are identical; classification reflects general alignment with evaluation criteria.

Premium Tier

  • Advanced or optimized formulations

  • Strong alignment with clinical research

  • Enhanced delivery systems or standardization

  • High level of manufacturing transparency

Mid-Tier

  • Solid alignment with common clinical dosing and forms

  • Reliable manufacturing practices

  • Good balance of quality and cost

Value Tier

  • Basic formulations that reflect standard ingredient forms

  • Cost-effective options

  • May have fewer advanced features but still meet fundamental quality criteria

Tier classification reflects formulation characteristics—not marketing claims or brand reputation.

What We Do Not Consider

Product selection is not based on:

  • Marketing claims or advertising language

  • Popularity or online trends

  • Brand recognition alone

  • Unverified testimonials

The goal is to maintain a consistent, evidence-informed framework.

Affiliate Relationships and Transparency

Some products featured on this site may include affiliate links. If you choose to purchase through these links, Verus PhytoMed™ may earn a commission at no additional cost to you.

Product selection is based on predefined evaluation criteria. Affiliate relationships do not influence which products are included or how they are categorized.

Context and Limitations

Dietary supplements are studied in a wide range of populations and research designs.

Even when a product aligns with clinical research:

  • Individual responses may vary

  • Study populations may differ from real-world use

  • Long-term outcomes may not always be available

For these reasons, product evaluation is presented as a tool for comparison—not a guarantee of results.

Our Goal

The goal of this framework is to provide:

  • A consistent and transparent method for evaluating supplements

  • Alignment between research and real-world products

  • Clear criteria for comparing options across different price ranges

This approach is intended to support informed decision-making within a broader health strategy that includes nutrition, physical activity, and medical care when appropriate.
