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 Biotin (Vitamin B7)?

Biotin is a water-soluble B vitamin serving as a cofactor for carboxylase enzymes involved in fatty acid synthesis, gluconeogenesis, and amino acid catabolism. It is widely marketed for hair, skin, and nail health, though clinical evidence is mixed.

Mechanism of action: Biotin functions as a covalently-bound cofactor for five carboxylase enzymes: acetyl-CoA carboxylase, pyruvate carboxylase, propionyl-CoA carboxylase, methylcrotonyl-CoA carboxylase, and oxaloacetate decarboxylase. These enzymes are critical for fatty acid synthesis, gluconeogenesis, and leucine metabolism.

Clinical Evidence Summary

Below are 5 key clinical studies on Biotin (Vitamin B7). Nutra Comp analyses 22+ studies in its full clinical evidence report.

Systematic review2019PMID: 30681787

Biotin supplementation for hair and nail disorders: systematic review

Population: 18 studies

Key finding: Biotin supplementation improved hair and nail outcomes primarily in individuals with biotin deficiency. Evidence in non-deficient populations was limited.

Review of clinical data2020PMID: 32182294

Biotin and nail brittleness: a clinical review

Population: 3 prospective studies

Key finding: Biotin (2,500 mcg/day for 6 months) increased nail thickness by 25% and reduced splitting in women with brittle nails.

Systematic review2019PMID: 31496068

Biotin and blood sugar metabolism

Population: 5 RCTs

Key finding: High-dose biotin (5–10 mg/day) combined with chromium showed modest improvements in fasting glucose in type 2 diabetes.

Clinical review2018PMID: 29543307

Biotin interference with lab tests: clinical advisory

Population: Case series and lab data

Key finding: High-dose biotin supplements (>1,000 mcg/day) can interfere with immunoassay-based laboratory tests, including thyroid function and troponin assays.

Review2021PMID: 33260899

Biotin and skin health: mechanism review

Population: Multiple studies

Key finding: Biotin deficiency causes dermatitis and alopecia, but supplementation benefit in non-deficient individuals remains under-studied.

Frequently Asked Questions

Is biotin FDA approved?

Biotin is an essential B vitamin sold as a dietary supplement. The Daily Value is 30 mcg. Supplement doses are typically 100–300× the DV.

Does biotin actually help hair growth?

Evidence is strongest for biotin-deficient individuals with brittle nails and thinning hair. In non-deficient people, clinical evidence for hair growth is limited. Many marketed doses far exceed what studies support.

What dosage is used?

2,500–10,000 mcg/day for hair/nail support. Important: high-dose biotin can interfere with certain blood tests (thyroid, troponin). Discontinue 48–72 hours before laboratory testing.
