Can I take more than 10 mg of Lutein?
There is limited amount of studies done on the maximum amount of lutein you should take per day, but 20 mg is considered safe.
Not all type of Lutein is the same.
Free lutein in lipid form is best absorbed by the body. A single egg contains about 0.20 mg of free lutein. The average intake of lutein is <1.7mg. Our eye care vitamins from Herbaland contains free lutein sourced from organic marigold flowers, which has 10mg of Lutein per serving.

Why is Eye Nutrition Important?
Age-related Macular Degneration (AMD) is the leading cause of blindness over age 60. AMD impacts of our central vision - visual acuity, which is important for visually-demanding daily activities, like reading, driving, writing and seeing people's faces.
Pregnant women require daily source of Lutein and DHA (from Omega-3) for proper development of the baby's brain and eyes. This is especially critical during the first 3 months. When the baby is born, the eyes are still developing and its important to have healthy eyes since 80% of learning is done through vision.
