Zeaxanthin, also known as 3,3'-dihydroxy-β-carotene, is a type of oxygen-containing carotenoid found in green leafy vegetables, flowers, fruits, Chinese wolfberry, and yellow corn. It is an isomer of lutein and is commonly present in nature as all-trans isomers (AlLE-ISo-Mer). Zeaxanthin, with a molecular formula of C40H56O2 and a molecular weight of 568.85, is a new oil-soluble natural pigment.
At Qingdao Borong Biotechnology Co., Ltd., we offer high-quality zeaxanthin that is part of carotenoid mixtures along with lutein, β-carotene, and cryptoxanthin. Incorporate zeaxanthin into your diet to benefit from its natural properties.
