Be sure to consult with your doctor first before taking any . Indeed, CNV develops with oxidative stress and chronic inflammation adjacent to RPE, Bruchs membrane and choriocapillaris because of vascular endothelial growth factor (VEGF) upregulation. In agreement with the aforementioned neuroprotective effects of such xanthophyll carotenoid, the potential use of astaxanthin in the setting of nonarteritic anterior ischemic optic neuropathy (NAION), which is the most common cause of acute ischemic vision loss in people aged over 50 [49] has recently been suggested. ), 3Medical and Surgical Sciences Department, Alma Mater Studiorum University of Bologna, 40138 Bologna, Italy. Subjects receiving astaxanthin experienced a significant relief from eyestrain compared to the placebo group [66]. Fratter A., Biagi D., Cicero A.F. We have intentionally avoided products with synthetic dyes, artificial flavors, chemical preservatives, and other cheap, unnecessary excipients. In another study by Benlarbi-Ben Khedher, the effect of astaxanthin on aldolase reductase (AR) activity, which is a key enzyme in the polyol pathway responsible for the pathogenesis of diabetic microvascular complications, was assessed both ex vivo and in vivo using a rodent model of type 2 diabetes. Photoreceptors are exposed to extensive oxidative stress in the form of light and oxygen, so that the outer 10% of photoreceptor segments are shed daily [35]. 15+ Amazing Health Benefits of Astaxanthin for Eyes and Beyond Astaxanthin For Eye Fatigue and Computer Eye Strain 4. Oxidative stress results from a disturbance of the delicate balance between cellular pro- and anti-oxidant reactions, and acts as a key mediator in the pathogenesis of several human diseases.

The group treated with astaxanthin showed the preservation of histological and functional outcomes of diabetic retinopathy, which went together with reduced oxidative stress and inflammation, as suggested by reduced levels of oxidative mediators (8-hydroxy-2-deoxyguanosine, nitrotyrosine, and acrolein), increased levels of antioxidant enzymes (heme oxygenase-1 and peroxiredoxin) and decreased activity of the transcription factor nuclear factor-kappaB (NF-B) [16]. Eye Support is formulated with some of the most powerful antioxidant ingredients available - lutein, zeaxanthin, organic astaxanthin and black currant - for optimal eye support and healthy vision maintenance. http://creativecommons.org/licenses/by/4.0/. Conceptualization, G.G. The nonpolar carotenoids, lycopene and -carotene disordered the membrane bilayer and stimulated membrane lipid peroxidation, whereas astaxanthin preserved membrane structure and exhibited significant antioxidant activity [9,10]. Yang C.H., Albietz J., Harkin D.G., Kimlin M.G., Schmid K.L. There are two characteristics of astaxanthin that set it apart from other powerful antioxidants. Twenty-seven patients with nonadvanced AMD were enrolled and randomly divided into two groups: 15 patients had oral supplementation of vitamin C (180 mg), vitamin E (30 mg), zinc (22.5 mg), copper (1 mg), lutein (10 mg), zeaxanthin (1 mg), and astaxanthin (4 mg) daily for 12 months, whereas 12 patients had no dietary supplementation. There are a number of nutrients that promote eye function and visual performance, including vitamins A, C, D, and E; zinc and copper; the macular carotenoids lutein and zeaxanthin; and omega-3 fatty acids. *, In addition to all the essential vitamins and minerals you need for whole-body health, our multi delivers a plethora of vitamins, minerals, and botanicals that promote eye function and vision longevity: Vitamins A, C, and E deliver potent antioxidant actions that fight free radicals in the eye and support overall ocular health and function; trace minerals zinc and copper promote retinal function; and longevity phytonutrients lutein, zeaxanthin, and lycopene (which are innovative and unique additions to a multi) help combat oxidative stress in the eye and throughout the body. Since humans dont have the physiological machinery to synthesize carotenoids on their own, consuming carotenoids from a nutrient-dense diet and quality supplement regimen daily is critical to reap their many benefits! Indeed, immune cells are particularly sensitive to lipid peroxidation processes due to their high content of polyunsaturated fatty acids in membranes, and generally produce much more oxidative agents because of the important metabolic activity [21]. Otsuka T., Shimazawa M., Inoue Y., Nakano Y., Ojino K., Izawa H., Tsuruma K., Ishibashi T., Hara H.

Protective effects of a dietary carotenoid, astaxanthin, against light-induced retinal damage. Inflammation and oxidative stress act as components of a double-ended relationship. In the study by Yeh and coauthors, 50 female Wistar rats received an injection of streptozotocin (STZ) to induce diabetes and were then randomly selected into four groups that received daily for eight weeks: normal saline; 0.6 mg/kg astaxanthin; 3 mg/kg astaxanthin; 0.5 mg/kg lutein. Potential risks: In excess, they may turn . Additionally, astaxanthin acts against apoptosis by blocking p-ERk/ERK, cytochrome C, caspase 3,9 and Bax2/Bcl2 ratio [5]. Astaxanthin For Double Vision 5. The efficacy of this carotenoid in the setting of retinal diseases, ocular surface disorders, uveitis, cataract and asthenopia is reported in numerous animal and human studies, which highlight its ability of modulating several metabolic pathways, subsequently restoring the cellular homeostatic balance. Experts say yesand add that they're not only helpful but critical given the modern stressors our eyes are subject to. Zhang S., Tang M.B., Luo H.Y., Shi C.H., Xu Y.M. Your eyes are critical and metabolically active organs that require daily support from nutrients and phytonutrients that promote antioxidant protection, blue light filtering, ocular blood flow, lubrication, visual acuity, and more. Choi H.D., Kim J.H., Chang M.J., Kyu-Youn Y., Shin W.G. Moreover, astaxanthin showed a good safety profile and no adverse events have been reported in any clinical studies [6,7]. This research received no external funding. In this regard, Lin and coauthors investigated the effect of astaxanthin administration in an experimental rat model of NAION and showed that this carotenoid was able to preserve visual function and reduce apoptosis of retinal ganglion cells after ischemic insult. This high-potency astaxanthin supplement delivers 12 milligrams of sustainably sourced Icelandic astaxanthin with organic virgin coconut oil (for enhanced absorption) in just one daily softgel. The aim of the present paper is to provide a comprehensive review of the current clinical applications of astaxanthin in the treatment of a wide range of ocular diseases. On this basis, nutraceuticals like astaxanthin may be used not only to fill the nutritional gap (supplement use), but also to treat various pathological conditions by synergistically acting with conventional therapies (therapeutic use). The actual amounts of lutein and zeaxanthin in the supplements.

On the other hand, astaxanthin has been shown to significantly reduce retinal ganglion cells apoptosis that is responsible for the progression of retinal damage in glaucoma and in other optic neuropathies, as well as RPE cells death that causes AMD development [26,27]. With all these critical eye nutrients and a serious gap in the average American diet, the need for a comprehensive, daily eye supplement with targeted formulation is clear. Swanson Health's astaxanthin supplements for eyes are available in softgels ranging from 4 mg to 12 mg to be taken once per day, which is the same dosage range researchers say have produced the best results. Retinal ganglion cell death is a common feature of many retinal disorders such as glaucoma, optic neuropathies and diabetic retinopathy, whereas RPE cells death plays a key role in AMD pathogenesis. Results showed a marked reduction of AR activity in vivo and ex vivo following astaxanthin supplementation, thus supporting its role in both the prevention and early treatment of diabetic retinopathy [44]. We have an epidemic of tired and undernourished eyes. How Astaxanthin Can Benefit Your Eye Health | Care/of Light penetrates every layer of the eye, generating a large volume of ROS, and acquired factors such as persistent hyperglycemia, elevated intraocular pressure (IOP) and inflammatory stimuli contribute to accelerating oxidative reactions. Key Nutrients to Support Eye Health & Healthy Vision. Kaur A., Gupta V., Christopher A.F., Malik M.A., Bansal P. Nutraceuticals in prevention of cataractAn evidence based approach.

Astaxanthin: A mechanistic review on its biological activities and health benefits. Dry eye disease, which acts as the best model of an impaired ocular surface system, is characterized by a significant increase of oxidative stress markers and ROS, which are responsible for altering epithelial proliferation and differentiation homeostasis, as documented by decreased proliferation, upward migration and increased apoptotic cells, as shown in Figure 1, Panel D [60]. Due to its unique molecular structure, astaxanthin features some important biologic properties, mostly represented by strong antioxidant, anti-inflammatory and antiapoptotic activities. Lens proteins normally exist under a soluble phase, and such solubility accounts for transparency. In particular, it has been shown to enhance the phosphorylation of BAD, the downregulation of cytochrome c, and the activation of caspases 3 and 9 through the regulation of mitogen-activated protein kinase/p38 (p38 MAPK), as well as the stimulation of the PI3K/AKT survival pathway, which in turn lead to the reduction of mitochondrial-related apoptosis [5,26,28,29]. 10 milligrams lutein. While salmon, shrimp, lobster and other astaxanthin-rich foods are delicious and healthy, eating them . People tend to blink less when staring at a screen for extended periods of time (like, say, an entire workday), which affects the tear film and can lead to tired, sore eyes. Optometrist and author of What You Must Know About Food and Supplements for Optimal Vision Care Jeffrey Anshel, O.D., FAAO, adds another type of macular carotenoid to the list: meso-zeaxanthin. Astaxanthin Health benefits, dosage, safety, side-effects Astaxanthin is a naturally occurring red carotenoid pigment belonging to the family of xanthophylls, and is typically found in marine environments, especially in microalgae and seafood such as salmonids, shrimps and lobsters. from light (indoor and outdoor), pollutants, air temperature, and more. mindbodygreen ultimate multivitamin+ Go to review Best for dry eye support Life Extension Tear Support with MaquiBright Go to review Best for eye blood vessel support Thorne O.P.C.-100 Go to review Best botanical eye blend Pure Synergy Eye Protector Go to review Best AREDS-inspired formula Pure Encapsulations EyeProtect Basics Go to review Birer S., Arda H., Kilic D., Baskol G.

Ashley Jordan Ferira, Ph.D., RDN is Vice President of Scientific Affairs at mindbodygreen. Under certain circumstances, such as ageing, diabetes, steroids use and trauma, proteins leave the soluble phase to form high molecular weight aggregates, which account for the light scattering and opacity of the lens [56]. Therefore, the present review aimed at providing a comprehensive evaluation of current clinical applications of astaxanthin in the management of ocular diseases. Cataract development causes the opacity of the natural lens of the eye, thus leading to decreased visual acuity. Similar results were reported by Suzuki and coauthors, who adopted the same designed model of the study cited above, confirming the anti-inflammatory effectiveness of the microalgae-derived carotenoid, as suggested by reduced cellular infiltration, protein concentration and cytokines levels in the aqueous humor of a uveitis mice model [54]. It has been suggested that oxidative stress, besides directly damaging the retinal ganglion cell layer, may compromise the trabecular meshwork function, which is the major route for aqueous flow from the anterior chamber of the eye [48]. This powerful antioxidant has an array of benefits for the eyes. Such inflammatory cascade is invariably associated with increased oxidative stress. To date, evidence of astaxanthin use in the setting of age-related cataract, which represents the most common subtype of cataract encountered in clinical practice, is still missing. On this basis, several clinical trials have been conducted to assess the efficacy of various nutraceuticals in improving tear film stability and meibomian gland dysfunction in patients diagnosed with dry eye [62,63,64]. "Lutein is converted to another form [of zeaxanthin] called meso-zeaxanthin. [14,15,16]. At the end of the experimental period, neuroprotective effect of astaxanthin was determined via electrophysiological measurements of visual evoked potentials (VEP) together with the assessment of retinal apoptosis and oxidative markers expression. Sports Research Triple Strength Astaxanthin, Life Extension Tear Support with MaquiBright, Higher price point (due to comprehensive formula), Offered in formulas with and without zinc, No artificial colors, flavors, or sweeteners. Indeed, increasing levels of oxidative agents may augment NF-B activation by enhancing the rapid degradation of its inhibitor, IB, thus allowing nuclear translocation of the transcription factor NF-B and subsequent expression of several inflammatory mediators including iNOS, COX-2, TNF-, and IL-1 [19]. It builds a yellow-colored pigment shield to protect eye cells from the harmful effects of certain light sources, such as the sun. Persistent stress to the ocular surface, including tear hyperosmolarity, quantitative and/or qualitative changes of tears, and ultraviolet exposure also contribute to inflammatory involvement of the entire ocular surface. This guide discusses how each of these eye supplements can work to both optimize your vision and support your long-range eye health. Yadav U.C., Kalariya N.M., Ramana K.V.

In another multicenter, prospective, open-label randomized study, AMD patients treated with a combination of lutein/zeaxanthin and astaxanthin over a two-year period were more likely to report a significant improvement in visual acuity, contrast sensitivity and vision-related functions [41]. Your daily must-have essential for brain health and eye function, this omega-3 supplement delivers critical neuroprotective fatty acids EPA and DHA to promote eye integrity, visual acuity, retinal and macular health, and overall ocular function. Each double polyene bond can exist either as cis- or trans-geometric isomers. Astaxanthin's Rise to Popularity as Powerhouse Supplement February 24, 2022 When it comes to antioxidant supplements, nutrients like vitamin C and vitamin E often steal the show. Carotenoids are a unique class of powerful phytonutrient pigments (think yellow, orange, and red) found in a variety of plants, algae, and photosynthetic bacteria that offer whole-body health benefits. Previous authors that investigated the protective effect of astaxanthin against light-induced retinal damage have confirmed its beneficial role [31,38,39]. Following uveitis induced by a footpad injection of lipopolysaccharide (LPS), astaxanthin or prednisolone were administered intravenously 30 minutes before, at the same time as, or 30 minutes after LPS treatment. ; literature search, all the authors; G.G. This array of vision longevity botanicals is rounded out by supporting players Patagonian maqui berry (to promote eye hydration and fight against dryness caused by excessive screen time) and saffron (to support photoreceptor cells and reduce eye pressure) for a truly comprehensive formula that will support your eyes today, tomorrow, and way down the road.*. Carotenoids are classified into different groups: carotenes (e.g., beta carotenea form of vitamin A), xanthophylls (e.g., lutein, zeaxanthin, and astaxanthin), and a unique carotenoid category known as apocarotenoids that includes saffron flower bioactives crocin and crocetin. Floriani I., Quaranta L., Rulli E., Katsanos A., Varano L., Frezzotti P., Rossi G.C., Carmassi L., Rolle T., Ratiglia R., et al. . Andrew Lessman's ULTIMATE EYE SUPPORT with ASTAXANTHIN is a comprehensive blend of ingredients to protect the most fragile tissues of the eye and to promote vision health. HHS Vulnerability Disclosure, Help Unlike most antioxidants which work in the inner (e.g., vitamin E and -carotene) or in the outer side of the membrane (e.g., vitamin C), astaxanthin stretches through the bilayer membrane, providing protection against oxidative stress by scavenging reactive oxygen species (ROS) in both the inner and outer layers of the cellular membrane [4,5]. There is a growing body of evidence suggesting the beneficial pleiotropic effects of astaxanthin in the prevention and treatment of several ocular diseases, ranging from the anterior to the posterior pole of the eye. Antioxidant activities of astaxanthin and related carotenoids. $1.9B global astaxanthin market size in 2022. Indeed, in an experimental model of steroid-induced cataract, astaxanthin administration efficiently prevented lens opacification and significantly recovered glutathione levels, suggesting antioxidant activity as the main mechanism involved in cataract prevention [57]. As mentioned above, inflammation and oxidative stress are strongly associated and synergistically act as main pathogenic factors of ocular surface disorders [59]. Inflammatory mediators such as interleukin (IL)-1B, IL-6, IL-8 and TNF-, which are upregulated in many ocular diseases, increase the expression of ROS, which likewise lead to enhanced secretion of inflammatory cytokines, chemokines, and matrix-remodeling factors, thus altering local environment homeostasis, and finally contributing to the maintenance of a vicious circle of chronic inflammation and oxidative stress. Benlarbi-Ben Khedher M., Hajri K., Dellaa A., Baccouche B., Hammoum I., Boudhrioua-Mihoubi N., Dhifi W., Ben Chaouacha-Chekir R. Astaxanthin inhibits aldose reductase activity in.
