Abstract

fetched live from OpenAlex

Twenty-one nonvitamin, nonmineral dietary supplements commonly consumed by women in Canada were analyzed for isoflavones (formononetin, daidzein, genistein, glycitein), lignans (pinoresinol, lariciresinol, secoisolariciresinol, matairesinol), and coumestrol to complement our previously published food phytoestrogen database. Supplements containing soy or red clover had the highest concentrations of total isoflavones (728.2-35,417.0 ug/g) and total phytoestrogens (1030.1-35,517.7 ug/g) followed by licorice and licorice-containing supplements (41.3-363.3 ug/g isoflavones; 56.5-370.0 ug/g total phytoestrogens). Other supplements had considerably less isoflavones (</= 19.0 ug/g) and total phytoestrogens (</= 44.2 ug/g). Lignans were present in all (</= 298.9 ug/g), whereas coumestrol was either not present or present in only small amounts (</= 3.0 ug/g). Supplements differed in phytoestrogen profiles. The daily intake of isoflavones and lignans from some supplements may greatly exceed those from several servings of soy or vegetables. Hence, the intake of supplements should be taken into consideration in clinical or epidemiological studies for more accurate estimation of phytoestrogen intakes.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
