Amino acid

Lysine

L-Lysine

Mechanism

Lysin ist die erste limitierende essenzielle Aminosäure in typischen Pferderationen. Ist Lysin knapp, kann die Proteinsynthese trotz ausreichender Gesamt-Eiweißmenge limitiert sein. Besonders relevant für Wachstum, Trächtigkeit/Laktation und Muskelaufbau im Training.

Cautions

· Useful only when lysine limitation of the ration is established

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.
