Method for stress management and overall health status improvement and compositions used therein
Carotenoid compositions are described for management, treatment, and/or prevention of stress by reducing cortisol levels and/or improving distribution and/or density of macular pigment and thus improving overall health status. More particularly, a subject in need thereof for the method has disturbed macular pigment optical density or increased levels of cortisol as markers of psychological and physiological stress. Methods are also described of administering macular carotenoid compositions in daily doses of at least or about 0.005 mg/kg body weight of lutein, and at least or about 0.001 mg/kg body weight of meso-zeaxanthin and zeaxanthin isomer along with at least one food grade excipient and evaluating overall health status. The composition may be derived from plant extract containing xanthophylls and/or xanthophylls esters. The composition also reduces cortisol levels in the blood and relieves physiological stress, thus improving overall health status of a subject in need thereof.
1. A method for treatment of psychological stress and physiological stress in a subject, comprising:
a. identifying a subject in need thereof, wherein the subject in need thereof is affected by psychological stress as measured by macular pigment optical density (MPOD) levels and physiological stress as measured by blood cortisol levels;
b. administering a daily dose of macular carotenoid composition in an amount effective for increasing the MPOD levels and reducing the blood cortisol levels over a period of at least one month as compared to those of before the administration of the macular carotenoid composition so as to treat stress in the subject, the macular carotenoid composition consists of at least 85% by weight of xanthophylls, the xanthophylls being lutein and zeaxanthin isomers, of which at least 80% by weight being trans-lutein, at least 6% by weight being (R, R)-zeaxanthin and at least 6% by weight being (R, S)-zeaxanthin, wherein the macular carotenoid composition consists of at least 0.1 mg/kg body weight of the lutein and, at least 0.01 mg/kg body weight of the zeaxanthin isomers; and
c. measuring MPOD and blood cortisol levels; and
d. evaluating an improvement in overall health status of the subject.
2. The method according to claim 1 , wherein the subject in need thereof is administered with an effective amount of the macular carotenoid composition, the macular carotenoid composition is derived from the plant extract/oleoresin containing xanthophylls/xanthophylls esters, to improve overall health status of the subject.
3. The method according to claim 1 , wherein the subject in need thereof is a mammal.
4. The method according to claim 1 , wherein the subject in need thereof is a human.
