Consumer Labs summary on Vision Supplements - April 2019 (no mention of Vitamin D)
Lutein and zeaxanthin are believed to protect the macula of the eye (in the retina) from damage (see What It Does).
Many people consume relatively small amounts of lutein and zeaxanthin in their diets or have low levels of lutein in their blood; for them, taking a lutein supplement can slow the progression of age- related macular degeneration — although it won't improve the condition (see Getting lutein and zeaxanthin from food).
A dose of 10 mg of lutein appears to be better than a lower dose (6 mg). Higher dose products (e.g., 20 mg to 40 mg) are common, although it is not known if a higher dose is better. Nevertheless, 20 mg has been shown to be safe in a 6-month study.
It's not clear whether the "free" or "ester" form, or a natural or synthetic source, is better and it is not clear if there is added benefit with zeaxanthin.
Lutein and zeaxanthin at a reasonable dose (10 to 20 mg) can be obtained for as little about 15 cents per day (see What CL Found).
Other ingredients, particularly zinc, may be beneficial in slowing the progression of age-related macular degeneration. Vision formulas with these ingredients as well as lutein and zeaxanthin are available, although significantly more expensive than getting lutein/zeaxanthin alone. The formula with the strongest clinical evidence is Bausch + Lomb PreserVision AREDS Lutein (see What CL Found — Vision Formulas). One vision formula failed testing, containing only 9% of its listed lutein. To enhance absorption, it is best to take lutein and zeaxanthin supplements with a fatty meal. However, consumption of certain foods and supplements may decrease absorption of lutein and zeaxanthin (see Concerns and Cautions).
