Lutein, from California supplement company Jarrow Formulas, promises to support health in all parts of your vision. The company has extensive experience – decades of it – working with dietary supplements and ingredient essential for proper nutrition. They combine modern science with traditional medicine, like many other supplement companies. But Jarrow has a large audience, has been around a very long time, and has won more awards than the average supplement company. Their good reputation seems well earned.
Lutein contains the following ingredients: Lutein, Zeaxanthin, Soybean oil, beeswax and mixed tocopherols, softgel consists of gelatin, glycerin and water.
Each capsule has 20 mg lutein and 1 mg zeaxanthin, both extracted from marigold flower petals. Both are antioxidants found in various plants, foods, and the human eye. In the latter, it’s specifically the lens, retina, and macula. It’s thought that they protect your eyes from harmful light waves and certain types of eye diseases like cataracts. Several studies point to the effectiveness of lutein and zeaxanthin, especially with a balance of vitamins and minerals, in maintaining healthy vision. Zeaxanthin isn’t as well studied as lutein so it needs more research before aggressively promoting its benefits.
There isn’t an official recommended daily allowance (RDA) for lutein or zeaxanthin. The American Optometric Association recommends a serving of 2 mg a day for zeaxanthin, and 10 mg a day for lutein. Most studies have used doses of 10 to 20 mg of each ingredient without ill effects. Mostly these nutrients are studied in relation to treatment or prevention in diseases like cataracts and age related macular degeneration (AMD). It might be most effective in people over the age of 50, although its general benefits aren’t well known for people of all ages.
- One of the lowest priced supplements of lutein and zeaxanthin that still works. Although some people don’t feel a difference in their vision after taking Lutein, it seems to be more of a protector than enhancer. Having good amounts of both nutrients in your daily diet can prevent or treat eye diseases.
- There isn’t a lot of evidence backing up Jarrow’s decision to have 20 mg lutein and 1 mg zeaxanthin as their formula. 10 mg of lutein would have been sufficient, and more than 20 mg can turn your skin slightly yellow. An ideal formula might be 10 to 15 mg lutein and 2 to 5 mg of zeaxanthin.
The overall reaction to Lutein is good, as hundreds of people who’ve used the product have left positive reviews. Some people do say that it didn’t have a clear effect on their visual health, but results seem to vary widely. Natural variation in human biology and diet is likely responsible for this. If you’re only consuming 1 to 5 mg of lutein a day, this will definitely be a product for you. Your doctor may also recommend a product like this if they feel it’s best. There is definitely some evidence to show that lutein and zeaxanthin can do a lot to protect your eyes from cataracts and age related mascular degeneration (AMD).
