Lutein, zeaxanthin and astaxanthin are classified as xanthophylls, viz. hydroxyl derivatives of carotenes, which are compounds showing strong health-promoting properties. They affect proper functioning of many internal systems and organs. Human body is not able to synthesize the above mentioned xanthophylls and their intake with food is relatively low, therefore the range of dietary supplements with those compounds keeps developing and shortage thereof may be replenished. The objective of the research study was to review dietary supplements containing lutein, zeaxanthin and astaxanthin, that were available in the Polish market in a period from 5th July to 31st October 2019. The profile of dietary supplements was developed on the basis of information on the packets, in the leaflets attached to those packets and on information on the websites of pharmacies, herbal stores and nutrients-selling stores. Within the period studied 233 dietary supplements were found: 72 with lutein, 2 with zeaxanthin, 42 with astaxanthin, 105 with lutein and zeaxanthin, 6 with lutein and astaxanthin and 6 with all three carotenoids. In a recommended daily dose, the content of the compounds discussed depended, first of all, on the indications for use of the preparations and it ranged 0.02 ÷ 40 mg as for lutein, 0.032 ÷ 9 mg as for zeaxanthin and 0.005 ÷ 40 mg as for astaxanthin. The dietary supplements containing lutein (62 % of preparations) and zeaxanthin (84 % of preparations) were intended to ensure proper vision. In the case of preparations with astaxanthin, their comprehensive effect was pointed out and they were recommended for use in persons with cardiovascular diseases (28 % for each).
