XANTHOPHYLL COMPOSITION COMPRISING LUTEIN AND ZEAXANTHIN WITH ENHANCED BIOAVAILABILITY

摘要

The present invention relates to a xanthophyll composition comprising selective isomers of trans-R,R lutein and trans-R,R zeaxanthin in preferred particle size and pharmaceutically and/or nutraceutically acceptable excipients such as carriers, solubility enhancers, bioavailability enhancing agents, antioxidants and optionally flavoring agents with selective ratio which exerts enhanced bioavailability. The xanthophyll composition at least 80% of total xanthophyll comprised of at least 65% by weight of trans-R,R lutein and at least 10 % by weight of trans-R,R zeaxanthin, which is prepared combinedly from marigold and paprika oleoresins with definite proportion to produce the preferred ratio of trans-R,R lutein and trans-R,R zeaxanthin.
