Lutein and zeaxanthin are two important nutrients found in various parts of the body, including the retina and eye lenses. Acting as powerful antioxidants, they are like an internal pair of sunglasses, filtering out harmful UVA/UVB and blue light. Additionally, they aid in reducing night glare, enhancing visual sharpness, and improving color contrast.
Research indicates that boosting levels of these carotenoids can lead to better visual function while also protecting against the onset and advancement of eye conditions like macular degeneration, glaucoma, and other eye diseases.
Damage caused by free radicals can contribute to various eye diseases and other diseases. Studies have demonstrated that lutein, zeaxanthin, and mesozeaxanthin are powerful antioxidants capable of neutralizing free radicals. By doing so, they help prevent damage to healthy cells and reduce the risk of associated diseases. 1
Macular Degeneration, Lutein and Zeaxanthin
Lutein and zeaxanthin serve as protective agents against oxidative damage and inflammation, both of which are contributing factors to chronic eye conditions such as cataracts and macular degeneration.2
A study conducted over more than 20 years in 2015 revealed a remarkable finding: individuals with the highest intake of lutein and zeaxanthin experienced a staggering 41% reduction in the risk of advanced macular degeneration. 3
Clinical studies have demonstrated that older adults who are already afflicted with macular degeneration can benefit from taking lutein and zeaxanthin supplements. These supplements have been shown to slow the progression of the condition and improve visual function. 4
Inflammation and Macular Degeneration
Studies have found that lutein helps the immune system and reduces inflammation in the eyes, easing various types of eye inflammation caused by toxins. 5 Since age-related macular degeneration (AMD) has similarities with a long-lasting, widespread inflammation in the body, researchers are now looking at how lutein might not just help the eyes but also reduce inflammation throughout the body. 6
Glaucoma and Carotenoids
Glaucoma stands as a leading cause of vision impairment, potentially leading to gradual loss of vision. Often termed the “silent thief,” glaucoma typically manifests without noticeable symptoms until an individual notices a decline in their peripheral vision. Clinical research involving glaucoma patients has shown that consuming carotenoids orally aids in safeguarding against the advancement of visual impairment while also enhancing visual acuity.7 89
Diabetes, Lutein and Zeaxanthin
Individuals with diabetic eye conditions, including diabetic retinopathy, commonly exhibit reduced levels of lutein and zeaxanthin compared to those without such conditions. Supplementing with these carotenoids has been shown to enhance visual function in these patients, resulting in improved clarity and contrast in vision.10 Furthermore, emerging research suggests that these carotenoids provide neuroprotective and anti-inflammatory benefits for the retina. 11
Computer Eye Strain
In modern times, many jobs and academic pursuits demand prolonged computer use, often compounded by frequent reliance on mobile phones. This extended screen time can lead to significant eye strain, vision problems like myopia, and challenges in adjusting focus between near and far objects, ultimately affecting concentration levels. Moreover, the increased exposure to harmful blue light emitted by LED screens exacerbates these issues. 12 However, studies have shown that macular carotenoids, such as lutein and zeaxanthin, play a crucial role in mitigating the adverse effects of excessive screen exposure. 13
Alzheimer’s Disease and Cognitive Health
Research indicates that vital nutrients like lutein and zeaxanthin, crucial for brain health, are often lacking in the brains of individuals with Alzheimer’s disease.14 Studies conducted under placebo-controlled conditions have demonstrated that a higher intake of lutein can lead to improvements in cognitive function. 15
Other nutrients can support eye health, including:
Astaxanthin
Astaxanthin is the compound behind the reddish-pink hue seen in salmon and shrimp. Research on the antioxidant properties of astaxanthin in relation to retinal injury is in its early stages but shows considerable promise. Initial studies suggest that astaxanthin may effectively mitigate retinal damage. 16
Saffron
A spice with a long history of use spanning centuries, saffron has been used to treat various health issues. It enhances visual performance and may alleviate symptoms associated with macular degeneration.17 18
Mesozeaxanthin
A carotenoid in the lutein family. Research studies have found that Mesozeaxanthin is abundant in the macula. The macula is the central part of the retina, where you get the clearest vision. It is the most powerful of the main 3 antioxidants found in the macula. When combined with lutein and zeaxanthin, Mesozeaxanthin is the most powerful. 19
Taurine
Taurine is a crucial nutrient with wide-ranging benefits for your body. From supporting night vision and eye health to enhancing cardiovascular fitness and brain function, its effects are diverse and impactful. As an amino acid and potent antioxidant, taurine is involved in vital processes throughout the body, including the brain and heart.20 It aids in waste removal from the retina, which is especially important in preventing the buildup of drusen linked to dry macular degeneration. Additionally, taurine supports cognitive function and neuro integrity, contributing to overall brain health.
Beneficial Omega-3s
These essential fatty acids play a crucial role in protecting the retina from age-related damage. 21 22 Research indicates that individuals with higher fish oil consumption have significantly lower risks of both early and late-stage age-related macular degeneration. 23 For each additional 1,000 mg of omega-3s consumed daily, the risk of early-stage macular degeneration decreases by 6% and late-stage degeneration by 22%.24 Remarkably, patients with the highest total dietary omega-3 intake see a staggering 49% reduction in the risk of developing wet macular degeneration compared to those with lower intake levels. 25
Good Food Sources of Lutein and/or Zeaxanthin
Green leafy vegetables, green peas, zucchini, pumpkin, brussels sprouts, asparagus, broccoli, carrots, eggs, corn and chocolate, bell peppers, and pistachios.
