What is supplement substantiation?

Substantiation is the process of gathering and documenting scientific evidence that supports the health claims you make on your supplement labels and marketing materials. The FDA requires that all structure–function claims be truthful, non-misleading, and substantiated by competent and reliable scientific evidence — typically clinical trials on healthy human subjects.

How does Nutra Comp's AI analysis work?

Nutra Comp searches PubMed for clinical trials relevant to your ingredient, filters for studies on healthy human subjects with oral administration, and uses AI to extract key data: p-values, effect sizes, study design, population details, and conclusions. It distinguishes between across-group and within-group significance and ranks evidence strength with a confidence scoring system.

What data sources does Nutra Comp use?

Nutra Comp primarily searches PubMed/MEDLINE, the world's largest biomedical literature database maintained by the U.S. National Library of Medicine. We focus on peer-reviewed clinical trials, randomised controlled trials (RCTs), meta-analyses, and systematic reviews.

Are the generated claims FDA-compliant?

Yes. Nutra Comp generates structure–function claims in strict accordance with the FDA Small Entity Compliance Guide. All claims avoid explicit and implicit disease references. However, we recommend having your legal/regulatory team review the final output before use, as Nutra Comp is a tool to assist — not replace — professional compliance review.

How long does a typical ingredient search take?

Most ingredient searches complete within 5–15 minutes, depending on the volume of clinical literature available. Compare this to the typical manual process which can take 40–100+ hours per ingredient when done by a human compliance expert.

Can I export my reports?

Absolutely. All clinical evidence reports, structure–function claims, and substantiation memos can be exported as professional PDF documents. These are formatted for easy sharing with your legal team, regulatory reviewers, or business partners.

What does 'ingredient searches per month' mean?

Each search is one ingredient analysis — for example, searching 'Ashwagandha' or 'Vitamin D3'. The search generates a complete evidence report, claims, and substantiation memo for that ingredient. Your monthly allowance resets on your billing date.

What Is Psyllium Husk?

Psyllium (Plantago ovata) husk is a soluble fibre supplement with FDA-authorised health claims for heart disease risk reduction. It is one of the most evidence-backed natural ingredients for cholesterol management and digestive regularity.

Mechanism of action: Psyllium forms a viscous gel in the gut that binds bile acids, increasing their faecal excretion. The liver compensates by converting more cholesterol to bile acids, reducing serum LDL. The gel also slows glucose absorption and promotes satiety.

Clinical Evidence Summary

Below are 3 key clinical studies on Psyllium Husk. Nutra Comp analyses 64+ studies in its full clinical evidence report.
