About Naturally ™ Eye Guard®
Lutein is abundant in dark green leafy vegetables such as kale and spinach, while zeaxanthin is present in plant sources such as corn and persimmons, as well as in animal-based chicken eggs at concentrations comparable to those in vegetables and fruits. is recognized. Commercial use of macular rotenoids has been achieved through extraction and purification from marigold (Tagetes erecta L.) petals (Figure 2) [6]. Naturally ™ Eye Guard® is formulated with XanMax® , a flagship crystal manufactured by Raffi-Chem Co., Ltd.*1. Zanmax® is a high-crystalline lutein/zeaxanthin product obtained from marigold using the company's patented manufacturing method (JP4848420).

About macular pigment
It is said that over 600 types of carotenoids have been isolated and characterized in nature. Among these, it is said that there are between 40 and 50 types of carotenoids contained in the foods we eat daily, including vegetables and fruits [1,2]. However, did you know that carotenoids, which are closely related to our vision, are extremely limited?
In 1945, Professor Wald of Harvard University discovered that yellow pigment existed in the center of the human retina, namely the macula (Figure 1). The pigment, called "macular pigment," is a carotenoid or xanthophyll that contains oxygen molecules, and it was found that it is probably lutein or a xanthophyll contained in green leaves itself, and the presence of this type of carotenoid was confirmed for the first time in the mammalian retina. [3]. Forty years after Professor Wald's discovery, research conducted by Bone et al. revealed that human macular pigment consists of two components that can be separated by chromatography: (3R,3'R,6'R)-β,ε- It was revealed that it is composed of carotene-3,3'-diol and (3R,3'R)-β,β-carotene-3,3'-diol. These components were identified as lutein and zeaxanthin, respectively [4].
The above research shows that among the many carotenoids derived from food, only two types, lutein and zeaxanthin, exist in the macular region of the retina, which controls our vision (metabolites produced in the body). except). The carotenoids that make up the yellow pigment in the macula (macular pigment) are mainly lutein and zeaxanthin, so some literature calls them macular carotenoids.
About scales for evaluating visual function
It has been reported in the past that lutein and zeachinsanthin, which are present in high concentrations in the macular region of the retina, may play an important role in regulating visual function.The research group led by Hammond et al. We investigated the effects of supplementation on vision [5].
In a randomized, double-blind, placebo-controlled study of 115 healthy young men and women between the ages of 20 and 40, those who took 10 mg of lutein and 2 mg of zeaxanthin a day for 1 year received a placebo (placebo drug). The following results were statistically significant compared to the non-treated group.
Increased macular pigment concentration (MPOD)
High levels of macular pigments (mainly dietary lutein and zeaxanthin) present in the macular region of the retina mentioned above.
Shorter photo stress recovery
Shortening the time it takes for a subject's eyes to be illuminated with light for 5 seconds, from when the target image is temporarily invisible to when the target image becomes visible again.
Improved color contrast sensitivity
A subject viewing a target image with a pattern of shades of light and light adjusts the intensity of the background blue light on his own, improving his discrimination ability until the yellow target image is no longer visible.
This result revealed that this is consistent with the results of past studies that reported that an increase in MPOD, which is composed of lutein and zeaxanthin, leads to improvement in visual function.
