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.

Folate (Vitamin B9): Clinical Evidence & Substantiation Summary

Clinical Trials

Strongest Evidence

Prenatal Health

Typical Dosage

400–1,000 mcg DFE/day

Common Forms

5-MTHF (L-methylfolate)

What Is Folate (Vitamin B9)?

Folate is a water-soluble B vitamin essential for DNA synthesis, cell division, and amino acid metabolism. It is especially critical during pregnancy for neural tube development. The active form, 5-MTHF (methylfolate), bypasses the need for MTHFR enzyme conversion.

Mechanism of action: Folate serves as a one-carbon donor in methylation reactions critical for DNA synthesis (thymidylate and purine production), amino acid metabolism (homocysteine to methionine conversion), and epigenetic regulation. The MTHFR gene polymorphism (C677T) affects folate metabolism in approximately 10–15% of the population.

Clinical Evidence Summary

Below are 5 key clinical studies on Folate (Vitamin B9). Nutra Comp analyses 94+ studies in its full clinical evidence report.

Cochrane meta-analysis2013PMID: 23440782

Folic acid supplementation and neural tube defect prevention

Population: 5 RCTs, 6,105 women

Key finding: Folic acid supplementation before conception and during early pregnancy reduced neural tube defect risk by 72% (RR 0.28, 95% CI 0.15–0.52).

Meta-analysis2020PMID: 32268543

Folate and homocysteine: a dose-response meta-analysis

Population: 25 RCTs

Key finding: Folate supplementation reduced homocysteine by 25% on average (p<0.001), with 5-MTHF showing superior effects in MTHFR C677T carriers.

RCT2018PMID: 30466985

5-MTHF vs folic acid: comparative efficacy

Population: 144 women

Key finding: 5-MTHF increased red blood cell folate more effectively than folic acid in women with MTHFR polymorphism (p=0.02).

Meta-analysis2018PMID: 29610056

Folate and cardiovascular risk reduction

Population: 30 RCTs

Key finding: Folic acid supplementation reduced stroke risk by 10% (RR 0.90, 95% CI 0.84–0.97), with greater effects in regions without mandatory fortification.

Systematic review2019PMID: 31433477

Folate and depression: a systematic review

Population: 11 studies

Key finding: Low folate status was associated with increased depression risk. Supplementation with methylfolate showed adjunctive benefits in treatment-resistant depression.

Frequently Asked Questions

Is folate FDA approved?

Folate is an essential B vitamin sold as a dietary supplement. The FDA has established a Daily Value of 400 mcg DFE. Folic acid in prenatal supplements is widely recommended by health organisations.

What is the difference between folic acid and methylfolate?

Folic acid is the synthetic form that must be converted to 5-MTHF by the MTHFR enzyme. Methylfolate (5-MTHF) is the active form that bypasses this conversion, beneficial for those with MTHFR gene variants affecting enzyme efficiency.

What dosage of folate is used in clinical studies?

The DV is 400 mcg DFE. Prenatal doses are typically 400–800 mcg. Higher doses (1,000–15,000 mcg) of methylfolate have been studied for mood support, particularly in treatment-resistant depression.
