Lutein is found in parts of the human brain, and may be associated with one’s memory, learning and language development. Many people also call Lutein “the eye vitamin”, as this micronutrient is essential for maintaining visual function.
As the human body cannot produce Lutein naturally, it is important that one consumes foods which are good sources of Lutein.
Protects body cells from oxidative stress1
Supports cognitive development and functioning2,3
Improves visual acuity4
Lutein has anti-inflammatory and anti-oxidative properties that are important for the brain and eye cells and other tissues of the body. Cell membranes and omega-3 fatty acids like DHA are particularly susceptible to oxidative damage from free radicals. Lutein together with other nutrients, like natural vitamin E, may aid in their protection.
The amount of Lutein accumulated in the brain correlates with cognitive efficiency, such as memory, attention, and learning. 2,3
The retina of the eye is an extension of the brain, and Lutein is equally important for maintaining good eye health. It protects the retina by absorbing damaging sun light. It has been demonstrated to improve visual clarity and lower the risk of eye illness.5
According to available clinical studies Lutein exerts the above-described benefits if consumed ~3-5 g/day. Lutein is safe up to 20 mg/day.6
A medium green bell pepper contain approximately 1.4 milligrammes of lutein. It has one of the highest levels of lutein content among all the other coloured peppers and vegetables.
The amount of lutein in your eye positively relates to the processing speed in your brain.4
