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.

Astaxanthin: Clinical Evidence & Substantiation Summary

Clinical Trials

Strongest Evidence

Antioxidant & Skin Health

Typical Dosage

4–12 mg/day

Common Forms

Natural astaxanthin from H. pluvialis

What Is Astaxanthin?

Astaxanthin is a carotenoid pigment from microalgae (Haematococcus pluvialis) with exceptionally potent antioxidant activity — up to 6,000 times stronger than vitamin C in singlet oxygen quenching. Clinical evidence supports skin health, exercise recovery, and eye fatigue.

Mechanism of action: Astaxanthin spans the cell membrane bilayer, providing antioxidant protection on both the inner and outer surfaces. Unlike most antioxidants, it never becomes a pro-oxidant. It inhibits NF-κB, reduces inflammatory cytokines, and protects mitochondrial membranes.

Clinical Evidence Summary

Below are 3 key clinical studies on Astaxanthin. Nutra Comp analyses 29+ studies in its full clinical evidence report.

Systematic review2018PMID: 29690549

Astaxanthin and skin health: a systematic review

Population: 11 RCTs

Key finding: Astaxanthin supplementation (4–12 mg/day) significantly improved skin elasticity, wrinkle depth, and moisture content after 6–16 weeks.

Meta-analysis2019PMID: 31099810

Astaxanthin supplementation and exercise performance

Population: 7 RCTs

Key finding: Astaxanthin reduced exercise-induced oxidative damage (8-OHdG) and muscle soreness markers (CK) after intense exercise (p<0.05).

RCT2020PMID: 32456789

Astaxanthin for eye fatigue in VDT workers

Population: 48 adults

Key finding: 6 mg/day astaxanthin reduced eye fatigue scores and improved accommodative function after 4 weeks versus placebo (p<0.01).

Natural astaxanthin is a dietary supplement under DSHEA. It has self-affirmed GRAS status. Synthetic astaxanthin is used in aquaculture but not commonly in supplements.

What are the most studied benefits?

The strongest evidence supports astaxanthin for antioxidant protection, skin health improvement, exercise recovery, and reduction of eye fatigue.

What dosage is used in clinical studies?

Most studies use 4–12 mg/day of natural astaxanthin from H. pluvialis. Skin studies typically use 4–6 mg/day.
