Floraglo
Also known as: Lutein, FloraGLO
Overview
Lutein is a carotenoid found in dark green leafy vegetables and marigold flowers. FloraGLO is a commercially available, unesterified form of lutein derived from marigold flowers, known for its high bioavailability. It is primarily used to promote eye health, particularly in reducing the risk of age-related macular degeneration (AMD). Lutein functions as an antioxidant and filters blue light, protecting the macula from oxidative damage. Research supports its efficacy in improving visual acuity and contrast sensitivity. While primarily recognized for its benefits to eye health, some studies also explore its potential effects on cognitive function and skin health. Lutein supplements are considered safe and well-tolerated, making them a popular choice for individuals seeking to support their eye health.
Benefits
Lutein supplementation, particularly with FloraGLO, is primarily known for its benefits to eye health. Studies have shown that it increases macular pigment optical density (MPOD), which is associated with a reduced risk of age-related macular degeneration (AMD). Research indicates improvements in visual acuity and contrast sensitivity with lutein supplementation. Some evidence suggests potential benefits for cognitive function and skin health, such as improved skin hydration and elasticity, though more research is needed in these areas. Lutein is particularly beneficial for individuals at risk of AMD and those with low dietary intake of lutein. Benefits in MPOD can be observed after 2-4 months of consistent supplementation.
How it works
Lutein functions primarily as an antioxidant, protecting tissues from oxidative damage. It also filters high-energy blue light, which can be harmful to the eyes. Lutein accumulates in the macula, increasing macular pigment density and enhancing visual function. This increased density helps to reduce the risk of AMD by protecting the photoreceptor cells from damage. The absorption and bioavailability of lutein are enhanced when consumed with dietary fats, facilitating its incorporation into the macula and other tissues.
Side effects
Lutein is generally recognized as safe (GRAS) and well-tolerated. Common side effects are not reported at typical dosages (10-20 mg per day). Uncommon and rare side effects are not well-documented in the scientific literature. No significant drug interactions have been reported. There are no known contraindications for lutein supplementation. It is considered safe for use across the lifespan, including infants and young children. However, as with any supplement, it is advisable to consult with a healthcare provider before starting lutein, especially for individuals with pre-existing health conditions or those taking other medications.
Dosage
The minimum effective dose of lutein is typically around 10 mg per day for eye health benefits. Optimal dosage ranges are generally between 10-20 mg per day. The maximum safe dose has been established as 2 mg/kg body weight per day by JECFA. Lutein is best absorbed when taken with meals containing fats. It is available in various forms, including capsules and liquid supplements. Dietary fats enhance its absorption. No specific cofactors are required for lutein to be effective. Consistency in daily intake is important to achieve and maintain benefits.
FAQs
How should I take lutein for optimal absorption?
Lutein is best absorbed when taken with meals that contain fats. This helps to increase its bioavailability and ensure it is effectively utilized by the body.
Is lutein safe to take with other medications?
No significant drug interactions have been documented with lutein. However, it is always best to consult with a healthcare provider before starting any new supplement, especially if you are taking other medications.
How long does it take to see benefits from lutein supplementation?
Improvements in eye health, such as increased macular pigment optical density (MPOD), may be noticeable after several months of consistent lutein supplementation.
Can lutein cure existing eye diseases?
Lutein is not a cure for existing eye diseases, but it may help prevent the progression of conditions like age-related macular degeneration (AMD) by protecting the macula.
