Lutéine 40 mg avec Zéaxanthine 5 mg | Extrait de souci | Santé oculaire

Lutein and zeaxanthin are carotenoid pigments that concentrate selectively in the macula and lens of the human eye, forming the macular pigment. They filter harmful high energy blue light before it reaches the photoreceptors, and act as antioxidants protecting retinal cells from oxidative damage. Lutein and zeaxanthin supplements support macular health, visual acuity, and contrast sensitivity, and are particularly relevant for adults with high blue light exposure from digital screens. Consult a healthcare practitioner before use.

The 40mg lutein / 5mg zeaxanthin ratio reflects the naturally occurring ratio of these carotenoids in the macula (approximately 8:1 lutein to zeaxanthin) and is the dose used in the AREDS2 clinical trial the landmark study that established lutein and zeaxanthin as the carotenoids of choice for macular health support. This high-potency dose is designed to meaningfully increase macular pigment optical density (MPOD), the measurable marker of macular carotenoid status.

Macular pigment is the yellow pigment formed by the selective accumulation of lutein and zeaxanthin in the macula the central region of the retina responsible for sharp, detailed central vision. Macular pigment optical density (MPOD) is the measurable marker of macular carotenoid status. Higher MPOD is associated with better contrast sensitivity, reduced glare sensitivity, and greater protection against blue light induced oxidative damage to photoreceptors. MPOD can be increased through consistent lutein and zeaxanthin supplementation.

Lutein and zeaxanthin absorb high energy blue light (wavelengths approximately 400–500nm) before it reaches the photoreceptors in the macula. This optical filtering reduces the amount of blue light induced oxidative stress on retinal cells. As digital screen use increases daily blue light exposure, macular pigment density becomes increasingly relevant for long term visual health. Lutein and zeaxanthin supplementation supports macular pigment density and blue light filtration capacity.

Lutein and zeaxanthin are fat-soluble carotenoids. Like all fat soluble nutrients, they require dietary fat for micellar solubilization in the small intestine and absorption into the lymphatic system. Taking lutein and zeaxanthin with a fat free meal significantly reduces absorption. Even a small amount of dietary fat (5–10g) is sufficient to support absorption a meal containing olive oil, avocado, nuts, or any fat-containing food is appropriate.

Lutein and zeaxanthin have an excellent safety profile with no established tolerable upper intake level. They are naturally occurring carotenoids found in leafy green vegetables and eggs, and have been studied in clinical trials at doses up to 20mg lutein daily for extended periods without adverse effects. High dose supplementation (40mg lutein) may cause carotenodermia a harmless yellowing of the skin in some individuals. Consult a healthcare practitioner for long-term use guidance.
