Products
Two product lines, one standard — Naturally Homologous Selenium-Peptide nutrition products and a women's pelvic floor restoration program.

Selenium-peptide complex · High selenium
Selenium-rich black wheat germ powder plus wheat oligopeptides, EDTC targeted enzymatic cleavage, naturally homologous selenium-peptide complex, molecular weight <500 Da, gluten-free (<20 mg/kg).
- 180 μg selenium per 5 g sachet, 30 sachets per box, mix with meals
- Full contraindication list and medication-interval guidance included
Suggested for: Thyroid and immune support / Preconception / Immune support for older adults

Selenium-peptide complex · High peptide
Enhanced small-molecule wheat oligopeptide ratio, focused on gut barrier function and nutrient absorption, following the same process and quality standards.
- Small-molecule peptides (<500 Da) are easy to absorb
- Shares the same raw material and process standards as the high-selenium version
Suggested for: Gut health focus / Nutritional support for older adults
Naturally Homologous Selenium-Peptide vs conventional selenium forms
Comparison data under controlled testing protocols, to help you understand the differences between forms; together with your lab baseline records you can track changes in your own markers.

Measurement basis and how to verify
- ① 24-hour selenium bioavailability · controlled testing protocol · measured against samples from the same batch, reported as the mean ± standard deviation of repeated runs. How to verify: batch test report
- ② 2-hour cell transport rate · controlled testing protocol · measured against samples from the same batch, reported as the mean ± standard deviation of repeated runs. How to verify: batch test report
- ③ Intestinal mucosa thickness recovery (7 days) · controlled testing protocol · comparative observation on samples from the same batch; a comparative result, not a clinical conclusion in humans. How to verify: batch test report
- 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 report
- 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 report
- 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 report
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.
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.
Research leads, journals and source links for each metric are listed in Science Center · Evidence Library; you can request batch test reports from a health advisor during a consultation.
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.
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.
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.
Case sources and updates
Shared stories are users describing changes in their own lab results, recorded as given in the reports they provided. They are individual experiences, not effect claims. When literature or test reports change, the latest original prevails and corrections can be submitted through Contact us.
