Brewer's yeast

Faex medicinalis

Bierhefe ist reich an B-Vitaminen, Aminosäuren und Spurenelementen. Sie wird traditionell als allgemeines Ergänzungsfuttermittel zur Unterstützung von Fell und Stoffwechsel eingesetzt. Spezifische equine Wirksamkeitsstudien zu klinischen Endpunkten sind selten.

How the Equiterna Score is built

The Equiterna Score combines three dimensions into a value of 0-100: science (40%), practical experience (30%) and safety (30%). It is transparently derived from evidence level, attributed sources (PubMed/journals), legal classification and cautions. The FEI doping status is shown separately as a competition-law note and does not enter the score. Commissions and vendor relationships have no influence on the score. In addition, the editorial safety rating caps the result: it limits the safety dimension and the overall tier (orange: at most solid). For entries rated red, no score is calculated at all. The rating never raises anything — a green rating does not lift a calculated value.

An editorial assessment of the evidence and safety situation — not a healing claim and not an individual recommendation. It does not replace veterinary advice.
