Amino acid

Methionine

DL-methionine

Mechanism

Methionin ist eine essenzielle, schwefelhaltige Aminosäure und nach Lysin häufig zweit-limitierend. Als Schwefellieferant ist es an der Bildung von Keratin beteiligt — und Keratin ist der Baustoff von Hufhorn UND Haar. Das erklärt, warum derselbe Engpass sich am Huf und am Fell zeigen kann und warum der Bedarf im Fellwechsel steigt, wenn das gesamte Haarkleid neu gebildet wird. Oft mit Biotin und Zink kombiniert. Sehr hohe Gaben sind nicht sinnvoll und können kontraproduktiv sein.

Cautions

· Überdosierung kann den Aminosäure-Haushalt stören

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.
