Lutein

Natural yellow carotenoid; lipid-soluble antioxidant

Lutein - 10% is a dietary carotenoid, which is derived primarily from marigold flowers. It functions through its antioxidant properties, specifically targeting oxidative stress in ocular tissues. This antioxidant activity is crucial for protecting the eyes against damage from free radicals. By absorbing excess light energy, it helps mitigate damage caused by blue and ultraviolet light exposure. Lutein - 10% is widely studied for its role in eye health, particularly in preventing or slowing the progression of age-related macular degeneration (AMD) and cataracts. Its presence in the macula and retina is critical for maintaining eye function and reducing the risk of disease. In addition, there is emerging research on its potential benefits for skin health and as an adjunctive support in neuroprotection. As a dietary supplement, Lutein - 10% is often incorporated into formulations for vision health, and its bioavailability is a significant focus of scientific investigation to maximize its efficacy in clinical applications.

Lutein - 5% is a carotenoid compound, which is derived primarily from the petals of marigold flowers (Tagetes erecta). This natural source is known for its high concentration of xanthophylls, which are essential for the product's activity. The mode of action of Lutein involves its capacity to absorb blue light and quench reactive oxygen species, thereby exerting protective antioxidant effects. This mechanism is vital in preventing oxidative stress in biological tissues. The primary applications of Lutein - 5% are in nutritional supplements and functional foods. It is extensively studied for its role in supporting eye health, particularly in reducing the risk of macular degeneration and cataracts. Additionally, Lutein is investigated for its potential in skin health, where it may contribute to photoprotection by filtering harmful high-energy wavelengths of visible light. Its integration into various formulations is designed to leverage its bioavailability and efficacy in maintaining health at the cellular level. As such, researchers continue to explore its biochemical interactions and potential therapeutic impacts within human health domains.

Lutein (Xantofyl) fights tumors, mutations, microbes, and may treat macular degeneration.

Lutein analytical standard provided with UV assay for quantitative titration.

Lutein - 20% is a carotenoid product, which is an extract derived from natural plant sources, such as marigold flowers (Tagetes erecta). It functions through its antioxidant capabilities, which involve scavenging free radicals and protecting cells from oxidative damage. This mode of action is critical for maintaining eye health, as lutein preferentially accumulates in the macula of the human eye, where it filters harmful blue light and supports visual function. In terms of applications, Lutein - 20% is widely used in the formulation of dietary supplements designed to support ocular health. It is also incorporated into functional foods and beverages, as well as cosmetic products aimed at promoting skin health due to its protective effects against light-induced damage. Furthermore, ongoing research explores its potential roles in cognitive health and chronic disease prevention, highlighting its importance in scientific studies focusing on aging and disease management.

Cyclic alcohol

Lutein - 95% is a purified carotenoid compound, which is derived primarily from the petals of the marigold plant, Tagetes erecta. This high-purity extract contains a significant concentration of lutein, a naturally occurring pigment known for its role in the human body, particularly in the eyes. The primary mode of action of lutein involves its antioxidant properties; it functions by neutralizing free radicals, thus protecting cellular structures from oxidative damage. Within the human eye, lutein is concentrated in the macular region of the retina where it helps to filter harmful high-energy blue wavelengths of light and maintains healthy cells. The application of Lutein - 95% is predominantly in research focused on ocular health, specifically in studying conditions such as age-related macular degeneration and cataracts. Furthermore, its use extends to nutritional supplementation, given its role in preventing or mitigating phototoxic damage. Additionally, its antioxidant capabilities make Lutein - 95% a molecule of interest in studies exploring the protection against oxidative stress in other systems beyond ocular health. This carotenoid's high purity ensures reliable results in experimental settings, making it a critical component in scientific investigations of visual health.

Lutein - 50% is a carotenoid compound, specifically a xanthophyll, which is derived from marigold flowers (Tagetes erecta). Carotenoids like lutein are pigmented compounds that occur naturally in plants and are responsible for their vibrant colors. Lutein is isolated and then concentrated to achieve a 50% purity, typically using processes such as saponification and crystallization. In terms of mode of action, lutein functions primarily as an antioxidant. It is known to filter high-energy blue light and neutralize free radicals, thereby protecting cells from oxidative damage. This ability to attenuate oxidative stress is vital in maintaining the structural integrity of ocular tissues. Lutein - 50% is commonly used in scientific research and formulation of dietary supplements aimed at promoting eye health. It is particularly noted for its role in supporting macular health and protecting against age-related macular degeneration (AMD). Beyond ophthalmic applications, its antioxidant properties are also explored in broader cellular health studies.
