The Two Most Harmful Lights for Eyes
Ultraviolet Light: Ultraviolet light is a type of invisible light. One of the functions of the eye’s lens is to filter and block ultraviolet light. Prolonged exposure to ultraviolet light causes some parts of the lens to become opaque, leading to cataracts.
Blue Light: Blue light has the shortest wavelength among visible light and is harmful, second only to ultraviolet light. While the eye’s lens can block ultraviolet light, it cannot block blue light! Blue light primarily relies on the eye’s second line of defense—the macular region’s lutein—to absorb and filter it.
Blue Light Filters
Blue light is abundant in LED lights, smartphones, TVs, computer screens, and other artificial light sources. In the smart age, our eyes are constantly exposed to blue light from electronic devices.
Lutein is internationally recognized as the most crucial nutrient for vision! Besides being present in the macula, lutein is also found in large amounts in the lens, cornea, choroid, ciliary body, iris, and sclera.
The human body cannot synthesize lutein on its own, so it must be supplemented externally.
Different Stability and Absorption Rates
Lutein esters have stronger light and heat stability than lutein. Lutein is typically found in plant tissues in the form of lutein esters, which convert to lutein when metabolized in the human body. Studies have shown that lutein esters have stronger light and heat stability than lutein.
The ability to remove free radicals, especially hydroxyl free radicals, is higher than that of natural lutein esters. Natural lutein esters are important carotenoid fatty acid esters with stability superior to that of free lutein.
Lutein esters have stronger gastric acid tolerance than lutein. Lutein esters have higher absorption and utilization rates than lutein, at 61.6%. This difference in bioavailability is due to lutein esters being lipid-soluble lutein. Because lutein is a type of carotenoid, and carotenoids are lipid-soluble vitamins, their activity in fat is higher, so lutein esters have a higher absorption and utilization rate than lutein.
Lutein Ester Microcapsule Powder
What is Microencapsulation Technology: Microencapsulation technology is the technique of embedding, encapsulating, and sealing solid, liquid, or gas substances in a micro polymer film, creating a solid particle product. This protects the encapsulated material, isolates it from the external environment, maximizes its original color, aroma, taste, performance, and biological activity, and prevents damage and loss of nutrients.
What is Microcapsule Powder: Microcapsule powder is a powder-like substance formed using microencapsulation technology, where solid, liquid, or gas substances are encapsulated with high-quality wall materials. The diameter generally ranges from 1 to 500 μm, with a wall thickness typically between 0.5 and 150 μm. This improves product stability, prevents mutual interference between various components, and facilitates easier absorption and utilization by the human body.
Advantages of Microcapsule Powder: 1. Easy to store; 2. Reduces the reaction of active substances to external environmental factors (such as light, oxygen, water), ensuring that effective nutritional components are not lost; 3. Controls the release of core materials, allowing useful ingredients to be slowly released for absorption, thereby improving nutrient utilization; 4. Effectively improves taste, masks and adjusts the odors of different nutrients, dissolving in the digestive tract to release contents and provide nutritional benefits; 5. Isolates active ingredients, maintaining the activity of various trace elements, nutrients, and active substances in the human body.
In summary, microcapsule powder not only preserves the original liquid, solid, or gaseous nature of substances, but also avoids the harmful ingredients of traditional capsules, achieving slow-release absorption and preventing the evaporation of nutrient components.
