Real-World Evidence: A Golden Opportunity for Nutritional Trials

Real-World Evidence: A Golden Opportunity for Nutritional Trials

In the pharmaceutical world, real-world evidence (RWE) has, let's face it, become a cornerstone of regulatory and commercial strategy. But in the nutritional space where perhaps products (or even very similar versions of the same product) are at market, the opportunity is even more exciting, and arguably still underexploited.

‍

Whether you're a consumer health brand, a probiotic startup, or a legacy multi-national supplement company, now is the time to rethink how you run trials and gather data. RWE has been proven to unlock deeper insights, stronger claims, and broader credibility not just in the scientific community, but the consumer trust space, too.

‍

Let's cover why this is the case.

‍

What Is Real-World Evidence... "Exactly"?

Real-world evidence (RWE) in it's most accepted definition is data collected outside of tightly controlled randomized controlled trials (RCTs). It captures how people use products in their actual day-to-day lives. As free-living human beings, this includes how they interact with many rich yet common variables including their diet, sleep, stress and exercise. We can even extend this to include factors around mood and relationship management - with friends, loved ones, colleagues and more - all of which feed back into this self-feeding metadata loop.

‍

In nutritional research, RWE often comes from:

• Participant-reported outcomes (ePRO) - you night have heard of patient-reported outcomes in the pharmaceutical industry
• Wearable devices and biometrics
• App-based food diaries or symptom trackers
• Retail or DTC consumer feedback loops
• Remote blood or stool test kits

This kind of data gives you context, volume and behavioral nuance that traditional trials can often miss.

Why RWE Matters So Much for Marketed Nutrition Products

‍

1. You Can Run Studies Without Withholding the Product

Unlike pharma, where the product may not yet be approved, nutritional brands can run trials with their actual customers. That means you're studying real users in real time, not theoretical patient groups.

‍

2. It Supports Stronger Claims and Messaging

Combining real-world usage data with targeted symptom improvement or health outcome measures (e.g., "reduced bloating in 80% of users within 2 weeks") strengthens your ability to make defensible, data-backed claims while staying within regulatory guidelines.

‍

3. It Scales More Easily and Affordably

Remote RWE studies can be run with thousands of participants without site visits, blood draws, or expensive CRO infrastructure. That’s a financial game-changer for fast-moving nutrition brands with tight margins.

‍

4. It Reflects How Consumers Actually Use the Product

In traditional RCTs, protocols are strict: "Take this capsule at exactly 9AM, on an empty stomach, every day for 30 days". That’s unfortunately not how most consumers behave.

‍

RWE shows you the full picture including variability in use, missed doses and co-consumption patterns so your data reflects the real-world impact of your product.

‍

What We Can All Learn From Real-World Nutrition Trials...

Here are some example insights that real-world data can reveal:

• Symptom patterns over time (e.g., sleep quality, gut discomfort, fatigue)
• User segmentation: who benefits the most? (e.g., women age 40–60 with IBS?)
• Adherence and habit formation: when and why do people drop off?
• Environmental factors: does stress or diet modify the product effect?
• Complementary products: what else are users taking with it?

This type of data can directly inform marketing, R&D, and customer engagement strategies...! An invaluable welath of data not traditional seen of value in the historical clinical trial setting.

How to Run a Real-World Evidence Study in Nutrition?

With tools like Trialflare, it’s easier than ever to capture RWE in an ethical, compliant, participant-friendly way. Here's a typical flow:

1. Recruit active customers or panel participants
   • Run digital recruitment via email, QR codes on packaging, social channels, or through recruitment companies we partner with.
2. Get remote eConsent
   • Use digital tools to provide study info, consent forms, and live researcher Q&As via video call if needed.
3. Collect baseline data
   • Gather demographic, dietary, and symptom history.
4. Track data longitudinally
   • Through in-app surveys, push notifications, wearables integration, or optional biomarkers (e.g., microbiome testing, salivary cortisone, vaginal swab or even blood sampling from home or at a local partner clinic).
5. Analyze and segment
   • Use dashboards to review trends, segment user groups, and detect product-response patterns.

‍

Regulatory and Ethical Considerations

Although nutritional trials don’t face the same regulatory burden as pharmaceuticals, RWE still needs to be:

• Ethically approved, with clear participant consent
• Data-protected under GDPR, HIPAA, or relevant local laws
• Transparent in methodology and endpoints, particularly if claims are involved

Investing in good study design and data protection pays off, not just for compliance, but for credibility with consumers, partners and regulators.

‍

The Opportunity

We’re at a turning point in evidence generation for nutrition and brands that are leaning into real-world evidence will gain:

• Sharper claims that resonate with regulators and consumers alike
• Higher trust and scientific legitimacy
• Faster product feedback loops
• Competitive differentiation in a crowded market

‍

With tools to run remote trials at scale and a consumer base increasingly open to sharing their health data, the time to act is now, and many companies and brands are realising that RWE is not just a 'nice to have' any longer - it's what will give you a competitive edge.
