What is O Lactescence Tech™Marigold Extract-Lutein Ester?

Marigold Extract-Lutein Ester is derived from marigold and is obtained by esterification of lutein. Lutein ester is an important component for eye health. It can effectively improve eye fatigue and promote eye development. It is suitable for children, young people and the elderly. However, lutein ester has problems such as poor fluidity, difficulty in tableting, and easy oiling.

O Lactescence Tech™ Marigold Extract Lutein Ester uses microcapsule technology to effectively encapsulate lutein ester, which can effectively overcome the original problems of poor fluidity, difficulty in tableting and strong fishy smell of lutein ester. Customers who use O Lactescence Tech™ can effectively reduce production costs and let users experience better taste, thus standing out in the fierce competition.

Functions of Marigold Extract-Lutein Ester

Lutein esters are broken down into free lutein after absorption by the human body, and have the basic function of supplementing the loss of lutein in the human body with crystalline lutein (the supplementary consumption should be ≤ 12 milligrams per day).

1.Supplement the macular pigment density in the macular area of the human retina, protect the macula, and promote macular development. Prevent macular degeneration and retinitis pigmentosa, and reduce the occurrence of vitreous membrane warts.

Functions of Marigold Extract-Lutein Ester (1)

There were no significant differences in the serum lutein concentrations and MPOD levels at baseline between the groups. The increased serum lutein concentration and MPOD levels at 3months were respectively, 89% and 38% in the free lutein group and 97% and 17% in the lutein esters group. The serum lutein concentrations in both groups and MPOD levels in the free lutein group increased significantly (p<0.05) from baseline. No significant differences in serum lutein concentrations and MPOD levels were seen between the groups. Three months after supplementation ended, the serum lutein concentration decreased; the MPOD remained elevated in both groups.

2.Antioxidants help prevent cardiovascular sclerosis, coronary heart disease, and tumor diseases caused by aging in the body.

Functions of Marigold Extract-Lutein Ester (2)

We investigated the antihypertensive effect of lutein on N-G-nitro-L-arginine methyl ester hydrochloride (L-NAME)-induced hypertensive rats. MAP in the lutein groups was dose-dependently lower than that in the L-NAME group. Lutein (2 mg/kg) significantly prevented the reduced heart rate induced by L-NAME. These findings suggest that lutein affords significant antihypertensive and antioxidant effects against LNAME-induced hypertension in rats.

3.Protect vision and alleviate symptoms of visual fatigue; (Blurred vision, dry eyes, eye swelling, eye pain, photophobia, etc.)

Functions of Marigold Extract-Lutein Ester (4)

Lutein intake of 0.72 (medium-lutein beverage group) and 1.44 mg/mL (high-lutein beverage group) relieved visual fatigue, ameliorated turbidity symptoms of impaired crystalline lenses, reduced hepatic MDA concentration, increased hepatic GSH concentration, and significantly increased the activities of the hepatic antioxidant enzymes SOD, CAT, GSH-Px, and GR in rats. These data suggest that a lutein-rich beverage is an effective and harmless way to increase the total anti-oxidation capacity of lenses and alleviate visual fatigue.

4. Prevention of AMD use

Natural lutein esters are hydrolyzed into free lutein and zeaxanthin by human lipase. They deposit at high concentrations in the macula of the human eye and can serve as absorbents for near ultraviolet blue light. By capturing free radicals, preventing or reducing oxidative and free radical damage to the retina, they exercise protective functions and effectively reduce the incidence of AMD.

Functions of Marigold Extract-Lutein Ester (5)

Blue-light photooxidative damage has been implicated in the etiology of age-related macular degeneration (AMD). The macular pigment xanthophylls lutein (L) and zeaxanthin (Z) and n-3 fatty acids may reduce this damage and lower the risk of AMD. Foveal protection was absent in xanthophyll-free animals but was evident after supplementation. After long-term xanthophyll deficiency, lutein or zeaxanthin supplementation protected the fovea from blue light-induced damage.
