Lutein & Zeaxanthin are xanthophylls, a type of carotenoid that can be found in dietary sources and are protective for the eyes and brain (1).
Lutein & Zeaxanthin Benefits
- Promotes healthy eye function during aging (ref)*
- Supports healthy cognitive function (ref)*
- Reduces oxidative stress in tissues, notably the eyes (in-vitro human eye tissue) (ref)*
Lutein & Zeaxanthin Mode of Action
Invest in your eye health to keep degeneration away. It’s now more important than ever to address eye health in this age of constant blue light exposure and eyestrain! Our Eye Support Vitamin Complex contains a combination of Lutein and Zeaxanthin which helps protect your eye health and supports your cognitive function. Remember that blue light exposure we mentioned? Blue light from devices and screens causes oxidative stress to eye tissues, and this vitamin complex provides free racial neutralization for those harmful stressors. Lutein and Zeaxanthin may also help to reduce visual fatigue, making it a supplement that everyone to the most advanced gamer can benefit from!
Lutein & Zeaxanthin are carotenoids which are a class of over 750 pigments synthesized by plants, photosynthetic bacteria, and algae. They are the sources of the red, yellow, and orange colors of many fruits, vegetables, and plants. The dietary intake of fruits and vegetables provide 40 to 50 carotenoids. The most common dietary carotenoids are alpha-Carotene, Beta-carotene, Beta-cryptoxanthin, zeaxanthin, lutein, and lycopene (2).
The most important benefit Lutein & Zeaxanthin provide for humans is the ability to protect the eyes and the brain. They absorb blue light because of their molecular bonds which allow the pigments to absorb approximately 90% of blue light. Blue light is a short-wavelength light and Lutein & Zeaxanthin protect the eye from these wavelengths and reduce oxidative damage to the eyes (2). Lutein & Zeaxanthin are known as “macular pigments” because they collect in the macula of the eye and the high concentration in the macula prevents ocular degeneration associated with aging (5).
Supplements containing Lutein & Zeaxanthin which are in a carrier oil are more efficiently absorbed than food sources of these carotenoids. Carotenoids that do not need to be released from the plant matrix, coupled with oil, improves the absorption rate (2). Pure Nootropics’ Lutein & Zeaxanthin Capsules contain Safflower oil for exceptional bioavailability.
Lutein & Zeaxanthin Dosage
Pure Nootropics’ Lutein & Zeaxanthin provide 10 mg of Lutein and 2 mg of Zeaxanthin per 1 capsule. Suggested use for adults is 1 capsule daily, or as directed by your healthcare practitioner.
