Floraglo Lutein

Also known as: FloraGLO® Lutein, lutein esters, xanthophyll carotenoid, Lutein

Overview

Lutein is a xanthophyll carotenoid found primarily in green leafy vegetables such as spinach and kale, as well as in marigold flowers. FloraGLO® Lutein is a specific formulation derived from marigold oleoresin, characterized by its unesterified form which enhances bioavailability and safety. Lutein is extensively studied for its role in promoting eye health, particularly in preventing age-related macular degeneration (AMD) and cataracts. Recent research also suggests potential benefits in cognitive function, skin health, and nutritional support for infants and pregnant women. Systematic reviews and clinical trials underpin lutein’s effectiveness across various health outcomes, making it a valuable nutrient in dietary supplements.

Benefits

Lutein is primarily recognized for its benefits to eye health, most notably evidenced by its role in enhancing macular pigment optical density (MPOD) and potentially slowing AMD progression. A clinical trial demonstrated a significant increase in MPOD among participants who supplemented with lutein over 24 weeks. A comprehensive Cochrane review further supports lutein and zeaxanthin supplementation in reducing the risk of developing advanced AMD. While secondary benefits for cognitive function and skin health are noted, the evidence in these areas is less robust. Key populations that benefit from lutein supplementation include the elderly and young children, particularly in terms of visual development.

How it works

Lutein functions as a powerful antioxidant, protecting the retina from oxidative damage and the effects of blue light exposure, both of which contribute to AMD. It accumulates in the macula, thus increasing MPOD and improving visual function. Lutein interacts with retinal lipids to shelter photoreceptors from damage, lowering the risk of degeneration. Its optimal absorption is achieved when consumed in lipid-based formulations such as FloraGLO® Lutein, which enhances its bioavailability.

Side effects

Lutein is generally recognized as safe (GRAS) when consumed through foods and dietary supplements. The clinical studies indicate minimal to no significant side effects, and no rare adverse effects have been reported. Due to its commendable safety profile, lutein is appropriate for a wide consumer base, including infants and pregnant women. Importantly, it does not display serious drug interactions or contraindications. The Acceptable Daily Intake (ADI) is set at 2 mg per kg of body weight per day, reinforcing lutein’s overall safety across different demographics.

Dosage

The recommended minimum effective dosage of lutein for eye health benefits is typically 10 mg per day, with common supplemental ranges between 10 mg and 20 mg depending on individual needs and formulations. For an average adult weighing 70 kg, the upper safety limit is approximately 140 mg per day, consistent with the established ADI guidelines. Users are advised to take lutein at any point during the day; however, absorption may be improved when consumed alongside meals containing fats, considering its lipophilic properties. FloraGLO® Lutein products are particularly noted for their enhanced bioavailability.

FAQs

Is lutein safe for everyone?

Yes, lutein is generally safe for all populations, including infants and pregnant women, with no significant side effects.

When should I take lutein?

Lutein can be taken at any time of day, but absorption may be better when consumed with fatty meals.

What results can I expect from lutein supplementation?

Users may observe increased MPOD and potential slowing of AMD progression over several weeks of consistent use.

Can lutein cure AMD?

No, lutein is not a cure for AMD; it supports eye health and may reduce disease progression.
