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 Rhodiola Rosea?

Rhodiola rosea is an adaptogenic herb traditionally used in Scandinavian and Russian herbal medicine. Clinical research supports its effects on fatigue reduction, stress resilience, cognitive performance under stress, and exercise capacity.

Mechanism of action: Rhodiola modulates the HPA axis and influences monoamine neurotransmitters (serotonin, dopamine, norepinephrine). Its active compounds — rosavins and salidroside — inhibit MAO-A and COMT enzymes, enhancing catecholamine signalling. It also activates AMPK and has neuroprotective properties.

RCT, double-blind2017PMID: 28219059

Stress management and the role of Rhodiola rosea

Population: 118 adults with burnout

Key finding: 400 mg/day of Rhodiola significantly improved burnout symptoms, emotional exhaustion, and stress perception after 12 weeks (p<0.01).

Systematic review2018PMID: 30411529

Rhodiola rosea supplementation and exercise performance

Population: 7 RCTs

Key finding: Rhodiola showed modest improvements in exercise endurance and perceived exertion, with stronger effects in untrained individuals.

RCT2015PMID: 26502953

A randomized trial of Rhodiola rosea for generalized anxiety disorder

Population: 80 participants with mild anxiety

Key finding: Rhodiola (200 mg twice daily for 14 days) significantly reduced self-reported anxiety, stress, anger, confusion, and depression scores vs. placebo.

Review of clinical studies2021PMID: 33992294

Neuroprotective effects of Rhodiola rosea

Population: Multiple studies

Key finding: Salidroside demonstrated neuroprotective properties through antioxidant mechanisms and BDNF upregulation in human and preclinical studies.
