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 Vitamin B12?

Vitamin B12 (cobalamin) is a water-soluble vitamin essential for nervous system function, DNA synthesis, and red blood cell formation. Deficiency is common in older adults, vegetarians, vegans, and those taking metformin or proton pump inhibitors.

Mechanism of action: B12 serves as a cofactor for two enzymes: methionine synthase (converting homocysteine to methionine, essential for DNA methylation) and methylmalonyl-CoA mutase (fatty acid metabolism). It is critical for myelin synthesis and nervous system maintenance.

Clinical Evidence Summary

Below are 5 key clinical studies on Vitamin B12. Nutra Comp analyses 89+ studies in its full clinical evidence report.

Systematic review2019PMID: 30547890

Vitamin B12 supplementation and cognitive function in elderly

Population: 12 RCTs

Key finding: B12 supplementation improved cognitive function in deficient elderly populations, with greater effects when combined with folate (p<0.05).

Meta-analysis2018PMID: 29473879

B12 supplementation and homocysteine reduction

Population: 16 RCTs

Key finding: B12 supplementation significantly reduced homocysteine levels (WMD: -3.2 μmol/L, p<0.001), a cardiovascular risk marker.

Systematic review2019PMID: 31496068

B12 and mood: a systematic review

Population: 9 studies

Key finding: Low B12 status was associated with increased risk of depression. Supplementation showed modest benefits in those with deficiency.

Review2020PMID: 32914701

Vitamin B12 and energy metabolism

Population: Clinical studies

Key finding: B12 supplementation reduced fatigue scores in deficient patients but showed no benefit in those with adequate B12 status.

RCT crossover2021PMID: 33865176

Methylcobalamin vs cyanocobalamin: comparative absorption

Population: 30 healthy adults

Key finding: Methylcobalamin and cyanocobalamin showed similar bioavailability at standard doses, with methylcobalamin having a slight advantage in tissue retention.

Frequently Asked Questions

Is vitamin B12 FDA approved?

B12 is an essential vitamin sold as a dietary supplement. The FDA has set a Daily Value of 2.4 mcg. Injectable B12 is an FDA-approved prescription medication for treating pernicious anaemia.

What are the most studied benefits of B12?

The strongest evidence supports B12 for nervous system support, energy metabolism, red blood cell formation, and homocysteine reduction. Benefits are most pronounced in deficient populations.

What dosage of B12 is used in clinical studies?

Most studies use 500–2,500 mcg/day orally. Higher doses are used because only a small percentage is absorbed. The DV is 2.4 mcg, but therapeutic doses are much higher.
