Dear Editor,

Lutein is a nutritionally beneficial organic tetraterpenoid pigment; its molecular formula and weight are C40H56O2 and 568.87144 g/mol, respectively. It is responsible for the yellow color of fruits and vegetables and is found in high levels in parsley, spinach, kale, egg yolk, and lutein-fortified foods (Shegokar and Mitri, 2012[29]).

Lutein has a wide range of beneficial health effects including antioxidant, anti-inflammatory, antiatherogenic, antihypertensive, antidiabetic, antiulcer, and anticancer effects (Miyazawa et al., 2013[22]; Johnson, 2014[13]; Erdman et al., 2015[8]; Manayi et al., 2015[19]). Furthermore, it is used to prevent eye diseases including age-related macular degeneration (AMD), cataract, and retinitis pigmentosa (Koushan et al., 2013[15]; Sulich et al., 2015[34]).

The commercial value of lutein is growing with the customary age-related macular degeneration applications. The lutein market is segmented into pharmaceutical, nutraceutical, food, pet foods, cosmetics, and animal and fish feed. Lutein shows a range of biological activities and health benefits in animals; therefore, herein, we have reviewed the most recent studies on lutein and its biological and pharmacological activities (Table 1(Tab. 1); References in Table 1: Song et al., 2015[32]; Sheshappa et al., 2015[30]; Crichton et al., 2015[6]; Lieblein-Boff et al., 2015[17]; Du et al., 2015[7]; Cheng et al., 2015[4]; Qiu et al., 2015[25]; Fatani et al., 2015[9]; Wu et al., 2015[44]; Huang et al., 2015[12]; Li et al., 2015[16]; Han et al., 2015[11]; Rafi et al., 2015[26]; Tian et al., 2015[37]; Casaroli-Marano et al., 2015[2]; Wang et al., 2014[42]; Niesor et al., 2014[23]; Su et al., 2014[33]; Sun et al., 2014[35]; Kon et al., 2014[14]; Promphet et al., 2014[24]; Furlani et al., 2014[10]; Serpeloni et al., 2014[28]; Matsumoto et al., 2014[20]; Vishwanathan et al., 2014[40]; Sen et al., 2014[27]; Min and Min, 2014[21]; Ma et al., 2014[18]; Xu et al., 2013[45]; Binawade et al., 2013[1]; Chang et al., 2013[3]; Tian et al., 2013[38]; Yajima et al., 2013[47]; Sung et al., 2013[36]; Costa et al., 2013[5]; Wang et al., 2013[41]; Yao et al., 2013[48]; Xu et al., 2013[46]; Vijayapadma et al., 2014[39]; Woo et al., 2013[43]; Sindhu et al., 2012[31]).
