How to Use: setting expectations up front
Nutritional support is not a short-term fix. Week by week we explain what may change, which markers to watch, and when to consult a doctor first.

Weeks 2–4
Subjective changes such as energy, digestion and skin tone may appear first; blood selenium levels begin to rise.
Weeks 4–8
Individual differences in focus, cold tolerance, skin condition and mood stability start to show.
Weeks 8–12
Recheck relevant markers (e.g. thyroid antibodies, hs-CRP) and compare with your baseline records.
Before you start
Leave a 2–4 hour gap from medicines such as levothyroxine; consult a doctor first if you have active autoimmune disease or are pregnant or breastfeeding.
Before starting, complete two preparations: the contraindication self-check and your lab baseline records — build your own reference data first, then observe changes.
Pre-use self-check
Spend 60 seconds ticking the items that apply to you to see whether you should consult a doctor first.

The self-check result is a reference only and cannot replace professional medical advice.
Who should consult a doctor first
- · People with active autoimmune disease
- · Women who are pregnant or breastfeeding
- · People taking anticoagulants or thyroid-related medication
- · People with chronic conditions or long-term medication use
Lab baseline records
Enter your marker values before and after use; changes are calculated automatically and compared with your baseline.
Lab baseline records
Enter your marker values before and after use to build a change comparison
How to fill it in: Marker name on the left, then the "before / after" values, then the unit on the right. For example, thyroid-stimulating hormone (TSH) 4.20 before and 2.80 after, unit mIU/L. When the unit is the same, use the copy icon on the right of the unit field to reuse the previous row's unit.
How to read the numbers on a lab report
- · Copy the "result" and "unit" for that item exactly as printed; do not convert or round the numbers yourself.
- · Use the most recent lab test before you started for "before", and the follow-up result afterwards for "after", so changes are easier to see.
- · Keep the marker name identical across rows so the same marker is not split into two lines.
Records are saved in this browser automatically and stay after a refresh or a new visit; you can export them as an image or a spreadsheet, or print them to hand to your doctor at a follow-up.Exports and prints also carry the next follow-up date estimated by the recheck reminder: Fri, 1 Jan 2027.
Enter before and after values for at least one marker to build a change comparison.
This tool only helps you keep your own records and calculate changes; it is not medical advice or an evaluation of results. Ask a licensed physician how to interpret the markers and what to do next.

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.
