Richer noted, if a patient is taking agents to thin the blood, because this particular vitamin promotes blood clotting. This may be an indication for a lutein-based antioxidant supplement.

The best supplements for macular degeneration contain the following ingredients, per recommendations based on the results of two major clinical studies:
- 500 mg of vitamin C.
- 400 IUs of vitamin E.
- 10 mg of lutein.
- 2 mg of zeaxanthin.
- 80 mg of zinc oxide.
- 2 mg of copper (also called cupric oxide)
They showed that lutein reduced the production and secretion of inflammatory cytokines, molecules that promote inflammation. The study aligns with other research that has suggested an important role for lutein in heart disease. Like other carotenoids, lutein is best absorbed with (unsaturated) fat in a meal.
There are no known toxic side effects of taking too much lutein or zeaxanthin. In some cases, people who eat large amounts of carrots or yellow and green citrus fruits can develop a harmless yellowing of the skin called carotenemia.

Many people think of lutein as "the eye vitamin." It is commonly taken by mouth to prevent eye diseases such as an eye disease that leads to vision loss in older adults (age-related macular degeneration or AMD), and cataracts. There is no good scientific evidence to support the use of lutein for other conditions.
