Isabelle Raymond, PhD, senior vice president, clinical and medical affairs at Nutrafol writes about how clinical research in the dietary supplement space requires a more tailored approach distinct from pharmaceutical trials.

There's a paradox at the heart of supplement research that the scientific community can no longer ignore: while consumer use of dietary supplements continues to surge, the framework for studying their efficacy remains trapped in an outdated paradigm that serves neither consumers nor healthcare providers.

The challenge isn't just about funding—it's about fundamentally rethinking how we approach supplement research in an era where consumers increasingly seek evidence-based solutions that include vitamins, minerals, and natural ingredients to support their health.

Industry-funded research is often met with skepticism, yet without it, many critical studies would never be conducted. The pharmaceutical industry has long funded its own clinical trials while maintaining scientific integrity through FDA-mandated protocols. However, since no such standardized clinical testing requirements exist for supplements, it is essential for brands to set and uphold rigorous research standards—investing in their products and conducting studies within the populations they are meant to serve.

That said, supplement research requires its own tailored approach rather than simply mirroring pharmaceutical guidelines. To advance the field, we need frameworks that account for the unique and layered challenges of studying supplements, including:

  1. Ingredient standardization: Ensuring consistency in supplement ingredients is crucial for producing reliable, reproducible results that can be confidently applied to broader populations.
  2. Randomized, placebo-controlled design: Leveraging gold standard study design to ensure efficacy is established and using applicable objective measures when possible to minimize bias- while still including subjective experience.
  3. Traditional usage vs. clinical evidence: Recognizing how historical use can complement, rather than replace, rigorous scientific studies.
  4. Study design for wellness-focused outcomes: Understanding that substantiating structure function claims necessitates distinct study parameters to effectively assess efficacy, rather than evaluating the same endpoints used in drug trials.

By evolving how supplements are studied, we can enhance credibility and ensure better consumer guidance. The solution isn't lowering standards—it's creating more appropriate ones. We need a collaborative approach involving academia, industry, and regulatory bodies to establish accepted guidelines for protocol design that maintain scientific rigor while acknowledging the unique aspects of natural products.

Several key changes could transform the landscape:

  • Well-defined clinical trial design guidelines and meaningful clinical outcomes
    • We need industry-wide consensus on an evidence-based framework that integrates multiple data sources and testing methodologies, ensuring both feasibility and scientific integrity. Unlike pharmaceuticals, supplements are intended to support and optimize wellness in generally healthy populations—not to treat disease. This distinction is critical. Outcomes should reflect improvements in baseline health and overall function, rather than relying on models built around disease treatment. To achieve this, we must integrate diverse methodologies and data sources that capture the full picture of supplement-driven outcomes, while maintaining feasibility and scientific integrity.
  • Stronger accountability in industry-funded research
    • While third-party oversight is already an established protocol, we must ensure its consistent implementation and increased transparency to further reinforce credibility.
  • Enhanced standards for levels of evidence
    • No single study can provide all the answers about a product, which is why a comprehensive clinical program encompassing diverse measures and populations is crucial for ensuring reliable, generalizable results. By integrating traditional usage data, and subjective experience with rigorous clinical trials, we can also achieve a more holistic evaluation of efficacy while maintaining the highest scientific standards.
  • Greater transparency in research communication
    • Acknowledging study limitations doesn’t weaken credibility, it strengthens it. Clearly communicating constraints ensures a more informed and trust-driven dialogue with consumers and the scientific community.

The current lack of alignment creates a lose-lose scenario: either essential research goes unfunded and unconducted, or studies are met with automatic skepticism due to industry involvement. To move forward, we must establish new research frameworks that uphold scientific integrity while accounting for the unique complexities of supplement studies to build a stronger, more credible evidence base that benefits both healthcare providers and consumers.

The future of supplement research doesn't lie in choosing between scientific rigor and practical reality—it’s about innovating to achieve both. The engagement of the healthcare community is critical because whether or not the research is there, consumers are already using these products. Isn’t it time we created better guidelines to study them?
