Beta-carotene

Provitamin A

Mechanism

Beta-carotene is a carotenoid and the most important plant-based vitamin A precursor; it acts as an antioxidant and accumulates among others in the corpus luteum and colostrum. Traditionally it is discussed as an adjunct in the context of broodmare fertility. Horses on good pasture are usually adequately supplied via fresh greens; the body's own conversion to vitamin A is regulated, so a vitamin A oversupply via beta-carotene is unlikely. In controlled studies, supplementation did raise beta-carotene concentrations in plasma and colostrum, but a clear benefit for the fertility of adequately supplied mares could not be demonstrated. Supplementation can be relevant above all with winter feeding of preserved forage low in carotene.

Cautions

· Horses on good pasture usually adequately supplied — avoid double supply with mineral feed
· Fertility effect in adequately supplied mares not clearly demonstrated

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.
