Does it contain enough lutein?
The recommended daily intake of lutein to ward of AMD and cataracts is 6-10 mg. Most lutein supplements contain just around 6 mg of the nutrient. While this just might be effective in some people, the dosage is really towards the lower side. To be safe, look for a supplement that contains more than 20 mg of it. Taking a slightly higher amount will make sure you get all the health benefits intended out of it.
