people are discovering the benefits of Lutein. A natural antioxidant
in their diets to maintain better health; in particular, people
concerned with age-related Macular Degeneration (AMD), the leading
cause of blindness in the industrialized world. As we age, the
macula becomes scarred from damage caused by exposure to ultra
violet light. More recently, scientific studies indicate that
Lutein or Lutea may also reduce the risk of other major chronic
diseases such as breast cancer, skin cancer and cataracts. Lutein
is the most abundant carotenoid. It is present in green vegetables,
such as spinach, kale, broccoli, brussels sprouts and certain
Lutein is a natural part of human diet when fruits and vegetables
are consumed. For individuals lacking sufficient Lutein intake,
Lutein-fortified foods are available, or in the case of elderly
people with a poorly absorbing digestive system, fortification
via a sublingual spray ensures maximum benefit to the eyes.
As early as 1996, Lutein has been incorporated into dietary
supplements. While no recommended daily allowance currently
exists for Lutein as for other nutrients, positive effects
have been seen at levels of 6 mg/day. The only definitive
side effect of excess Lutein consumption is the same observed
for carotene overdose: bronzing of the skin (carotenodermia).
The normal levels of Lutein found in a daily vitamin tablet
can be as low as 0.25mg. The human body cannot manufacture
Lutein and therefore it must be obtained from dietary sources.
