The Health Benefits of Lutein

Boost Eye Health With This Vitamin

Lutein is naturally found in a number of fruits and vegetables, especially those with deep green, orange, and yellow coloring. Sometimes referred to as xanthophyll, lutein is often used in treatment or prevention of eye diseases. Lutein supplements contain a natural substance classified as a carotenoid—a group of plant pigments with antioxidant effects. Lutein supplements provide a more concentrated supply of this antioxidant.

Health Benefits

Lutein supplements are typically used in alternative medicine for eye diseases, such as cataracts and macular degeneration. Known to build up in the retina and lens of the eye, lutein is thought to protect the eye from injury induced by free radicals, chemical byproducts shown to damage cells and contribute to the development of certain diseases.

Some alternative medicine proponents claim that lutein supplements can also help prevent colon cancer, breast cancer, diabetes, and heart ​disease.

To date, most of the studies on lutein's health benefits have focused on dietary intake of lutein. Those studies suggest that dietary intake of lutein may help protect against atherosclerosis, age-related macular degeneration, and cataracts. While few studies have examined the health effects of lutein supplements, there's some evidence that lutein supplements may improve eye health. Here's a look at two study findings:

Age-Related Macular Degeneration

Lutein supplements may improve visual function in people with age-related macular degeneration, a leading cause of blindness. In a 2004 study, 90 people with age-related macular degeneration took either lutein supplements, supplements containing lutein and other antioxidants and minerals, or a placebo for 12 months. Results showed that both supplement groups had significant improvement in visual function, while the placebo group showed no such improvement.

Visual Function

In a 2009 study of 37 healthy adults, researchers found that subjects who took lutein supplements for 12 weeks experienced improvements in visual function. The study's findings also suggest that lutein supplements may help treat vision problems brought on by long-term exposure to light from computer screens.

Possible Side Effects

Lutein and lutein supplements are likely safe when taken by mouth in appropriate amounts.

Certain patients, including those with skin cancer or cystic fibrosis, should be cautious when considering lutein supplements. It's important to consult your physician before taking any type of dietary supplement on a regular basis.

It's important to keep in mind that supplements haven't been tested for safety and dietary supplements are largely unregulated. In some cases, the product may deliver doses that differ from the specified amount for each herb. In other cases, the product may be contaminated with other substances such as metals. Also, the safety of supplements in pregnant women, nursing mothers, children, and those with medical conditions or who are taking medications has not been established. 

Dosage and Preparation

Consuming 6.9-11.7 mg of lutein per day in your diet appears to be safe. In research, lutein supplements have been used safely in doses up to 15 mg daily for up to two years. Additionally, health experts note that taking up to 20 mg of lutein both from the diet and supplements seems to be safe. 

What to Look For

To increase your lutein intake without the use of lutein supplements, include lutein-rich foods like kale, spinach, cabbage, green beans, mangoes, and papayas in your daily diet.

While lutein supplements may be of some benefit in the treatment or prevention of certain health problems, self-treating with the supplements (and avoiding or delaying standard care) is not recommended. If you're considering the use of lutein supplements, talk to your doctor about selecting a supplement and daily dosage that suit your health needs.
