Lutein Dosage for Macular Degeneration?

Lutein Dosage for Macular Degeneration?

Lutein is powerful carotenoid and is essential for keeping eyes in good health.  Pronounced “loo-teen” and sounding like the word “protein,” lutein is one of the most highly recommended items to take as a daily supplement to support healthy eyes and vision.

Why is lutein so important?

In the simplest sense it is because it protects your macula from blue light and sun damage.  It is highly concentrated in the macula, which is the part of the retina responsible for crisp, central vision.  A deteriorating macula leads to vision problems, such as with the eye disease age related macular degeneration, which is the leading cause of vision loss in people over the age of 55.

Why is lutein highly recommended from physicians and nutritionist?

Lutein has been studied for years and there are several researchers who believe that lutein  can increase visual acuity, and it may help prevent or slow the progression of eye diseases like macular degeneration and cataracts.

Lutein was studied in combination with additional items in the AREDS and AREDS 2 studies.  These studies are the two largest completed studies on age related eye disease and took a good look at people with age related macular degeneration.

The specific type lutein used in the AREDS and AREDS 2 was FloraGLO™ lutein, which is a high quality lutein and is more easily absorbed by the human body, so that it can be used to protect eyes and vision. This is important because you do not want cheap lutein.  Many vitamin manufactures use cheap lutein to save on manufacturing costs , which hurts the end consumer.

Lutein is found to naturally occur in foods  and good sources of lutein include green leafy vegetables like kale and spinach, as well as fruits and vegetables that are orange, yellow, or red in color.

The AREDS 2 study found that lutein combined with several other antioxidants, vitamins, and minerals slows the progression of age related macular degeneration.  The additional items that were studied include vitamin C, vitamin E, zinc, copper, and zeaxanthin.

One of these items called zeaxanthin is similar to lutein and is also a carotenoid.  It is also found concentrated in the macula and protects the macula from sun damage and blue light.  Lutein and zeaxanthin are like internal sunglasses for the eyes.  The best macular degeneration vitamins should contain both of these items.  The proper ratio of lutein to zeaxanthin is 5 to 1. This means that your eye vitamin should have 5 parts of lutein to 1 part of zeaxanthin.

What is the proper dosage of lutein?

The Internet has conflicting information about lutein and many websites claim that you should take 20mg or 40mg of lutein. However, Dr. Emily Chew stated that taking more than 10mg of lutein daily could be toxic. Dr. Chew was the deputy clinical director at the National Eye Institute who oversaw the AREDS 2 study.

In addition, the researchers from AREDS 2 studied 10mg of lutein, and the AREDS 2 formula contains 10mg of lutein along with the additional items studied.
