Abstract: The present invention relates to astaxanthin compositions for use in foodstuffs, food supplements or feedstuffs or as a medicament. Astaxanthin compositions which comprise up to at least 50% by weight, in particular at least 60% by weight, particularly at least 70% by weight, specifically at least 80% by weight or at least 90% by weight, based on the total weight of astaxanthin and astaxanthin derivatives in the composition, of an astaxanthin monoester with an aliphatic, unbranched C10C22-monocarboxylic acid have a particularly good bioavailability when at least 90% by weight of the monoester present in the astaxanthin composition is a monoester with precisely one aliphatic, unbranched C10-C22-monocarboxylic acid. They are therefore particularly suitable for the use in foodstuffs, food supplements or feedstuffs and for the therapeutic use as medicament and as constituent for medicinal preparations and pharmaceutical compositions.

Abstract: The present invention relates to astaxanthin compositions for use in foodstuffs, food supplements or feedstuffs or as a medicament. Astaxanthin compositions which comprise at least 50% by weight, in particular at least 60% by weight, especially preferably at least 70% by weight and specifically at least 80% by weight or at least 90% by weight, based on the total weight of astaxanthin and astaxanthin derivatives in the composition, of an astaxanthin monoester with a C18-1 fatty acid have a particularly good bioavailability. They are therefore particularly suitable for use in foodstuffs, food supplements or feedstuffs and for the therapeutic use as medicament and as constituent for medicinal preparations and pharmaceutical compositions.
