Jarrow Formulas Lutein supports eye health and visual function with lutein and zeaxanthin.* Lutein and zeaxanthin are natural antioxidant carotenoids found in dark green, leafy vegetables, and are important components of the macular pigment in the eye, which is responsible for focus and color differentiation.*
Lutein 20mg is a marigold supplement containing 20mg of lutein per capsule, which is the daily dose scientific studies consider to be most appropriate. Like Macula Plus, a formulation which also contains zeaxanthin, it helps support visual function.
The marigold is a plant used traditionally for its antioxidant properties and ability to support visual health. Its high content of lutein, a pigment found in the retina, is responsible for most of its benefits.
Lutein is one of 600 carotenoid pigments listed to date, of which around fifty are found in fruits, edible flowers and vegetables. Like zeaxanthin, it is part of the xanthophyll family. In terms of diet, lutein is found in egg yolk, green leafy vegetables (such as spinach and sorrel), yellow/orange vegetables (such as corn and carrots) and edible flowers including, of course, marigolds.
The foods richest in lutein are primarily dark green vegetables, the kind that are increasingly passed over these days in favour of ultra-processed food. Lutein intake is therefore now significantly lower among Western populations.
Marigold extract, standardised to 25% lutein, is aimed at anyone keen to ensure long term visual acuity and good eye health in general. No side-effects have been reported to date in those taking lutein supplements.
Lutein supplements contain a powerful antioxidant that plays an important role in human health. Most notably, lutein supplements support the eyes and promote healthy vision. It is also used to promote healthy skin and protect the lungs.
Derived from bright yellow marigold flowers, Lutein is a carotenoid pigment with nutritional value. When paired with its sister compound, Zeaxanthin, the two work synergistically in your body. Today, you can get 40 mg of lutein plus the added goodness of zeaxanthin in easy-to-swallow softgels!
Both free and esterified forms of lutein are found in nature, though the majority of lutein in foods is in the free form . Lutein esters are more stable and are often used in supplements. Free and esterified lutein are both bioavailable, but supplements containing free lutein may increase the serum/plasma lutein response more than supplements containing lutein esters . Only free lutein is absorbed, so esterified lutein requires an additional ester-hydrolysis step in the small intestine; this could explain the different response between forms .
The body of literature linking lutein to a reduced risk of AMD is richer than for the link between lutein and enhanced visual performance. However, using visual performance as the endpoint for intake recommendations would better align with the current dietary guidance for nutrients, which targets healthy populations.
Establishing intake recommendations for lutein would provide the public with yet another reason to eat more of the colorful fruits and vegetables lacking in our diets. Many consumers purchase products/supplements containing lutein, but without a recommendation, they may not be aware of the science that supports its role in health or know the appropriate intake level. The integration of specific intake recommendations for lutein (and potentially other bioactives) into nutrition public policy would also allow for easier evaluation of lutein intakes across populations; this would help assess whether populations are meeting recommendations .
According to a 2018 Nutrients review analyzing the results of many lutein supplement studies, a daily dose of 10 milligrams should give you ample eye health benefits, such as protecting your macula from blue light.*
A Progress in Retinal and Eye Research review explains that the macula lutea has a high concentration of lutein, zeaxanthin, and meso-zeaxanthin2. As you get farther away from the macula, fewer and fewer carotenoids are present.
What is the function of lutein and these other carotenoids in this portion of the retina? "Lutein helps to protect the macula by absorbing undesirable wavelengths of blue light and stopping them from reaching certain layers of the retina, reducing the likelihood of photo-oxidative stress," says optometrist Kelsea Brown, O.D. Hence: internal sunglasses.
All of this talk about supporting your eye health might have you asking a specific question: Can lutein enhance your eyesight? Brown offers her insight: "It does not directly function in the process of eyesight; however, it protects the macula and retina with its antioxidant properties."
The review states, "through all these mechanism(s), it is quite conceivable that [lutein] may exert a pivotal role in regulating immune pathways, modulating inflammatory responses, and combating oxidative [stress]." In other words? It's kind of a big deal.
And by the way, lutein might help your sleep health as well: A 2017 Foods study found supplementation with macular carotenoids was associated with enhanced sleep quality6, potentially due to the same mechanisms that support the carotenoids' ability to protect the eyes from blue light.*
Since the body can't produce lutein, it's essential to include foods rich in this nutrient in your diet. Some foods rich in lutein include dandelion, spinach, kale, basil, parsley, squash, egg yolk, and other green leafy veggies and fruits.
In addition to a nutrient-rich diet, another way to get adequate lutein is through supplementation. Premium eye health supplements may contain a variety of eye-supporting ingredients, including lutein.
As far as supplement dosage goes, the research is mixed. Experts suggest at least 10 milligrams of lutein daily, though evidence suggests dosages up to 24 milligrams6 of combined lutein and zeaxanthin a day can provide tailored benefits. (This is why mindbodygreen provides over 25 milligrams of this powerhouse carotenoid duo, lutein plus zeaxanthin, in eye health+ and another daily supplement essential, ultimate multivitamin+).
Incorporating more lutein-rich foods into your diet is an easy and safe way to ensure you properly support your eyes. When it comes to taking a lutein supplement, it has a strong safety profile, but you may consider consulting your health care provider out of an abundance of caution if you take certain medications or have underlying health concerns.
Lutein is an essential component of taking care of your vision and developing those very important "internal sunglasses" to protect your eyes from blue light. By eating foods rich in the nutrient and taking a high-quality supplement with sufficient lutein (like mbg's eye health+), you can give your eyes the love they desperately need to combat oxidative and light stress throughout your day.* Learn more about eye health+ here.
Zeaxanthin is a dietary carotenoid that also plays a role in eye health. Zeaxanthin and lutein are often taken together because they are found together in nature and work synergistically for eye health.

Healthy Origins Natural Lutein (Featuring Lutemax 2020) is a powerful combination of lutein with zeaxanthin RR and RS isomers. This unique blend of lutein and zeaxanthin plays a critical role in supplying the macula with vital, protective nutrients that support healthy vision as we age.*
Lutein and zeaxanthin are two types of carotenoids, yellow to red pigments found widely in vegetables and other plants. Though lutein is considered a yellow pigment, it appears orange-red in high concentrations.
In nature, lutein (LOO-teen) and zeaxanthin (zee-ah-ZAN-thin) appear to absorb excess light energy to prevent damage to plants from too much sunlight, especially from high-energy light rays called blue light.
In addition to being found in many green leafy plants and colorful fruits and vegetables, lutein and zeaxanthin are found in high concentrations in the macula of the human eye, giving the macula its yellowish color. In fact, the macula also is called the "macula lutea" (from the Latin macula, meaning "spot," and lutea, meaning "yellow").
It is believed that lutein, zeaxanthin and meso-zeaxanthin in the macula block blue light from reaching the underlying structures in the retina, thereby reducing the risk of light-induced oxidative damage that could lead to macular degeneration (AMD). 041b061a72
