Technology · Naturally Homologous Selenium-Peptide
From raw material to process and on to measurable markers, we translate technical language into facts you can follow. Specifications and the full comparison table are in the Product Center.
Naturally Homologous Selenium-Peptide absorption mechanism
Made from selenium-enriched black wheat germ and processed with EDTC targeted enzymatic cleavage to form "natural organic selenium + small-molecule wheat oligopeptides (< 500 Da)", supporting transport and utilization in the body.
Raw material and process
We judge category scarcity from the raw-material side, and fix process parameters and key stages on a controlled production line to build repeatable process know-how.
Expressing results through measurable markers
We use measurable markers such as absorption rate and bioavailability as the language of results, so product performance can be compared and re-checked.
Safety performance data
Under controlled testing protocols: gut adverse-reaction rate 2.2%, serum selenium excess rate 0%, offering a gentler option.
In-vitro activity: evaluation basis and comparison dimensions
In-vitro activity studies observe how different antioxidant ingredients behave under controlled experimental conditions; results vary with concentration, test system and assay method, so figures from different studies should not be compared directly.
- Comparison categories: common antioxidant ingredients (such as vitamin-type antioxidants) and different forms of selenium.
- Evaluation directions: in-vitro free-radical scavenging capacity and changes in oxidative-stress related markers.
- Presentation: only the experimental basis and comparison dimensions are described here; no specific figures against other ingredients are listed.
Basis: All in-vitro activity content on this page describes experiments run under controlled testing protocols; specific figures and assay methods follow the batch test report, which can be requested from a health advisor during consultation.
The above describes the basis of in-vitro experiments only; it is not an efficacy comparison claim against other ingredients and does not represent how the product performs in actual use.
Comparison with conventional selenium forms

How to verify: batch test reportLiterature correspondence: indirectly related · Intestinal mucosa thickness recovery (7 days) — intestinal mucosa and gut barrier are gut-environment themes tracked in that direction, so the link is indirect; the figure comes from comparative observation under controlled testing, not a clinical conclusion in humans.Related evidence direction: Microbiome · gut-thyroid axis; Example lead built into that direction: Association Between Gut Microbiota and Autoimmune Thyroid Disease: A Systematic Review and Meta-Analysis.
- ④ Increase in fatigue tolerance time (min) · controlled testing protocol · tolerance time change recorded under the controlled testing protocol; a comparative result, not a clinical conclusion in humans. How to verify: batch test reportLiterature correspondence: no matching direction yet · Increase in fatigue tolerance time (min) — fatigue tolerance is recorded by us under a controlled testing protocol and the four current directions do not cover this topic; you can search the box below by keyword for public research on it.Related evidence direction: no matching evidence direction yet
- ⑤ Incidence of gastrointestinal adverse events · controlled testing protocol · adverse event incidence counted under the controlled testing protocol; sample size and statistical method are given in the test report. How to verify: batch test reportLiterature correspondence: indirectly related · Incidence of gastrointestinal adverse events — the incidence of gastrointestinal adverse events relates to the gut topics tracked in the gut-thyroid axis direction, so the link is indirect; the incidence is a statistical result under the controlled testing protocol.Related evidence direction: Microbiome · gut-thyroid axis; Example lead built into that direction: Association Between Gut Microbiota and Autoimmune Thyroid Disease: A Systematic Review and Meta-Analysis.
- ⑥ Rate of above-range serum selenium · controlled testing protocol · share of above-range serum selenium counted under the controlled testing protocol; thresholds and reference ranges are given in the test report. How to verify: batch test reportLiterature correspondence: mechanism background · Rate of above-range serum selenium — serum selenium levels and safe ranges are one focus of selenium supplementation research in the thyroid direction, offering mechanism-level background; the rate is a statistical result under the controlled testing protocol.Related evidence direction: Thyroid · selenium and nodules; Example lead built into that direction: Selenium and thyroid diseases.
You can request the batch test report and statistics notes behind every figure above from a health advisor during a consultation; each report records the testing laboratory, batch number and test items so you can check them one by one.
Literature correspondence describes only how each metric relates to the research directions in our evidence library. The figures in the table come from controlled testing and batch test reports; they are not conclusions of those papers and are not a claim of efficacy.
Process highlight: selenium-rich black wheat germ as the raw material, with EDTC targeted enzymatic cleavage forming a naturally organic selenium plus small-molecule wheat oligopeptide complex (< 500 Da).
The values above are based on batch test reports and illustrate differences between forms; they are not a claim of efficacy or a promise of results, and individual absorption and response vary. This product is a dietary supplement. It is not a medicine and is not intended to diagnose, treat or prevent any disease.
The testing-protocol notes and the verifiable public links to the original literature are in the Evidence library section above; batch test reports can be checked with a health advisor on request.

This direction tracks clinical and review studies on selenium, thyroid antibodies (TPOAb / TgAb) and autoimmune thyroiditis, for a view of research progress in this field. How this direction relates to our claims: We believe selenium nutrition is relevant to the day-to-day management of thyroid-related markers such as thyroid antibodies, and that any change should be verified with measurable markers and public literature together; this direction provides the literature background for that view and does not represent a specific product effect on those markers.

Content sources and how we compile them
Every figure and claim on this page states its source and how it was collected, so readers and machines can check each item against the original record.
Literature sources and searching
Evidence library entries come from peer-reviewed journals indexed in PubMed, each listing journal, publication year and DOI or PMID with a link to the original. Every evidence direction carries its own search query.
Entry example: Frontiers in Endocrinology (2023) · DOI 10.3389/fendo.2023.1133000, with journal and a link to the original.
How test data is collected
Cellular transport rate and 24-hour selenium bioavailability come from controlled tests on same-batch samples, reported as the mean of repeated measurements plus or minus standard deviation. Pesticide residue is non-detect after a qualified third-party laboratory tests 108 items per batch.
Test example: 2h cellular transport rate 89.6%, measured against same-batch controls as the mean of repeated measurements ± standard deviation, per the batch test report.
Basis for operating statistics
The repurchase rate uses our internal statistical basis over the last full calendar year, aggregated from repeat purchases in that period. The statistical note and batch reports can be reviewed on request.
Statistic example: first selenium-peptide line repurchase rate 40%, based on the last full calendar year, with the methodology note available on request.
