Eye Health Proprietary Blend
Also known as: Eye Health Proprietary Blend, Lutein, Zeaxanthin, Vitamin E, Flavonoids, Xanthophyll Carotenoids, Lutein and Zeaxanthin Blend
Overview
The Eye Health Proprietary Blend is a combination of dietary supplements, primarily lutein and zeaxanthin, often with added antioxidants like vitamin E and flavonoids. Lutein and zeaxanthin are xanthophyll carotenoids found in leafy green vegetables, while vitamin E is a fat-soluble vitamin, and flavonoids are plant-based antioxidants. This blend is designed to support eye health, particularly in reducing the risk of age-related macular degeneration (AMD) and improving visual performance. These ingredients act as antioxidants, protecting the eyes from oxidative stress. Research on these ingredients is well-established, with studies showing significant benefits for eye health, such as increasing macular pigment optical density (MPOD) and improving visual outcomes in individuals with eye diseases. The blend is available in various forms, including capsules and softgels, and is often recommended to be taken with meals containing fat to enhance absorption.
Benefits
The Eye Health Proprietary Blend offers several evidence-based benefits for eye health. Lutein and zeaxanthin significantly increase MPOD, which is associated with better visual performance and a reduced risk of AMD. Studies have shown that xanthophyll-rich supplements can enhance visual acuity and decrease photostress recovery time, particularly in individuals with existing eye diseases. Furthermore, certain combinations of eye supplements have been observed to improve contrast sensitivity at low spatial frequencies. A meta-analysis indicated that the weighted mean difference (WMD) for MPOD increase was 0.05 (95% CI, 0.03-0.07), and for visual acuity improvement in patients with eye disease, the WMD was -0.04 (95% CI, -0.07 to -0.01). Benefits can typically be observed within several weeks to months of consistent supplementation.
How it works
The Eye Health Proprietary Blend works primarily through the antioxidant properties of its components, reducing oxidative stress in the retina. Lutein and zeaxanthin increase MPOD, which filters blue light and protects the macula from damage. These ingredients interact with the visual system by enhancing retinal health. The macular pigment, composed of lutein and zeaxanthin, is a key target. Bioavailability of lutein and zeaxanthin can be enhanced with dietary fats, facilitating their absorption and utilization in the body. This combined action supports overall eye health and visual function.
Side effects
The Eye Health Proprietary Blend is generally considered safe when used as directed. Common side effects are rare, but some individuals may experience gastrointestinal upset. Allergic reactions are also rare. Due to the vitamin E content, there is a potential for interaction with blood thinners, so caution is advised for individuals taking these medications. There are no established contraindications, but individuals with bleeding disorders should exercise caution due to vitamin E. Pregnant or breastfeeding women should consult healthcare providers before use. While generally safe, it's important to adhere to recommended dosages to minimize any potential adverse effects.
Dosage
For lutein and zeaxanthin, doses often start at 10 mg combined per day. The typical optimal dosage range is 10-20 mg of lutein and 2-5 mg of zeaxanthin per day. There is no established maximum safe dose for lutein and zeaxanthin, but high doses of vitamin E should be avoided. It is best taken with meals containing fat to enhance absorption. Capsules or softgels are common forms. Dietary fats enhance absorption. There are no specifically required cofactors, but a balanced diet supports overall effectiveness.
FAQs
When is the best time to take this supplement?
Take the supplement with meals, especially those containing fats, to enhance the absorption of lutein and zeaxanthin.
How long does it take to see results?
Improvements in eye health and visual performance can typically be observed within several weeks to months of consistent supplementation.
Can this supplement cure existing eye diseases?
No, these supplements do not cure existing eye diseases but may help prevent their progression and improve visual function.
Are there any risks associated with taking this supplement?
The supplement is generally safe, but individuals on blood thinners should exercise caution due to the vitamin E content. Pregnant or breastfeeding women should consult their healthcare provider.
What is MPOD and why is it important?
MPOD stands for macular pigment optical density. It refers to the concentration of lutein and zeaxanthin in the macula, which protects the eyes from blue light and oxidative damage, thus supporting visual health.
