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 Spirulina?

Spirulina (Arthrospira platensis) is a cyanobacterium microalgae and one of the most nutrient-dense foods on earth. Clinical evidence supports its effects on lipid profiles, blood pressure, blood sugar, and antioxidant capacity.

Mechanism of action: Spirulina's active compound phycocyanin inhibits NADPH oxidase and COX-2, reducing oxidative stress and inflammation. Its high protein content (60–70%) provides all essential amino acids. It also contains gamma-linolenic acid (GLA), chlorophyll, and carotenoids.

Clinical Evidence Summary

Below are 3 key clinical studies on Spirulina. Nutra Comp analyses 35+ studies in its full clinical evidence report.

Meta-analysis2016PMID: 27259333

Spirulina supplementation and lipid profile: a meta-analysis

Population: 12 RCTs, 807 participants

Key finding: Spirulina significantly reduced total cholesterol (WMD: -36.6 mg/dL), LDL (WMD: -32.3 mg/dL), and triglycerides (WMD: -39.2 mg/dL, all p<0.001).

Meta-analysis2019PMID: 30487456

Spirulina and blood pressure: a systematic review

Population: 8 RCTs

Key finding: Spirulina supplementation (2–8 g/day) significantly reduced systolic blood pressure (WMD: -4.4 mmHg, p=0.002) in hypertensive subjects.

Meta-analysis2019PMID: 31206184

Spirulina and glycaemic control

Population: 7 RCTs

Key finding: Spirulina significantly reduced fasting glucose (WMD: -5.0 mg/dL, p=0.04) with greater effects at doses ≥4 g/day.

Frequently Asked Questions

Is spirulina FDA approved?

Spirulina has GRAS status and is sold as a dietary supplement under DSHEA. Quality and contamination testing are critical due to potential heavy metal accumulation.

What are the most studied benefits?

The strongest evidence supports spirulina for lipid profile improvement, blood pressure reduction, and blood sugar management.

What dosage is used in clinical studies?

Most studies use 1–8 g/day of spirulina powder. The lipid-lowering meta-analysis found significant effects starting at 1 g/day.
