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 Collagen Peptides?

Collagen peptides (hydrolysed collagen) are bioavailable fragments of collagen protein, the most abundant structural protein in the body. Clinical interest has surged in recent years, with evidence supporting benefits for skin elasticity, joint health, and bone density.

Mechanism of action: Collagen peptides are digested into di- and tri-peptides (hydroxyproline-containing) that are absorbed and distributed to connective tissues. They stimulate fibroblast activity in the dermis, chondrocyte activity in cartilage, and osteoblast activity in bone. Specific peptides act as signalling molecules, increasing endogenous collagen synthesis.

Clinical Evidence Summary

Below are 5 key clinical studies on Collagen Peptides. Nutra Comp analyses 41+ studies in its full clinical evidence report.

Key finding: Collagen supplementation (2.5–10 g/day for 8–24 weeks) significantly improved skin elasticity, hydration, and dermal collagen density vs. placebo.

Systematic review2015PMID: 26362110

Role of collagen hydrolysate in bone and joint health

Population: 8 RCTs

Key finding: Collagen supplementation (10 g/day) significantly reduced joint pain in athletes (p=0.024) and improved joint function in osteoarthritis patients.

Systematic review2018PMID: 30368550

Effects of a collagen peptide supplement on skin, nails, and hair: A systematic review

Population: 7 RCTs

Key finding: Collagen peptide supplementation (2.5–5 g/day) significantly increased skin elasticity by 15–25% and reduced wrinkle depth by 20–31% after 8 weeks.

RCT, double-blind, placebo-controlled2018PMID: 28177710

Frequently Asked Questions

Are collagen supplements FDA approved?

Collagen supplements are sold as dietary supplements and do not require FDA approval. Hydrolysed collagen from bovine, marine, and poultry sources has a long history of safe use. Claims must be limited to structure–function claims under DSHEA.

What are the most studied benefits of collagen peptides?

The strongest evidence supports collagen for skin health (elasticity, hydration, wrinkle reduction), joint health (pain reduction, improved function), and emerging evidence for bone mineral density support in postmenopausal women.

What dosage of collagen is used in clinical studies?

Dosage varies by indication: 2.5–5 g/day for skin benefits, 10 g/day for joint health, and 5 g/day for bone density. Studies typically run 8–24 weeks to see results.
