is a natural pigment found in many fresh vegetables. A member of
the carotenoid family that includes beta carotene, lutein is the
only one of the nonprovitamins found in significant
concentration in the macula and crystal lens in the human eye.
Scientific research has found that lutein is helpful in
preventing and lessening the damage associated with age related
macular degeneration, a leading cause of blindness among adults.
It also may help prevent cataracts, and the most recent research
has suggested that it may also reduce the risk of coronary
disease and colon cancer.
and zeaxanthin are the two carotenoids found in high
concentration in the macula of the eye where they seem to
protect against the damage caused by age, UV radiation and free
radicals. In various studies, it has been shown that including
more lutein and zeaxanthin in the diet can slow the progression
of macular degeneration, and may prevent the formation of
Scientists believe that macular degeneration may be the result
of oxidative damage to the tissues in the eye. It’s been
suggested that the macular pigment confers protection through
absorbing harmful UV rays and serving as an antioxidant to
capture and bind free radicals before they can irreparably
damage the eye. Because lutein and zeaxanthin are two pigments
found in high concentration in the macula, and because they have
proven antioxidant capabilities, scientists have focused on
these nonprovitamins as a possible preventive for eye
deterioration as we age.
addition, some promising new research suggests that lutein and
zeaxanthin may also play a role in preventing atherosclerosis
(hardening of the arteries) which is a major cause of coronary
problems and heart attacks.
Benefits of Lutein:
related macular degeneration is the leading cause of blindness
in adults over the age of 50. The effects of AMD are
irreversible. In numerous studies, lutein has proven beneficial
in reducing and slowing the progress of damage to the macula of
studies have been undertaken to determine the effectiveness of
lutein in protecting the eye against the formation of cataracts.
Two different studies involving nearly 100,000 health
professionals over the age of 50 showed that adults with the
highest levels of lutein intake in their diets have 20% fewer
against Colon Cancer
Researchers at the University of Utah Medical School studied
over 4,000 adults, half of whom were diagnosed with colon
cancer. They found that a higher intake of lutein over the
previous two years was associated with a 17% lower risk in the
incidence of colon cancer.
against Coronary Disease
Researchers in Los Angeles studied the effect of lutein
supplementation on the progression of atherosclerosis – a
leading cause of heart attacks – in about 500 utility workers
between the ages of 40 and 60. Their conclusion supports the
hypothesis that increased lutein intake protects against the
development and progression of atherosclerosis.
Side Effects of Lutein:
extremely high dosages, there are no reported adverse side
effects to lutein supplementation.
Though scientists have not yet established exactly how lutein
works in the body, many studies have shown that it is effective
in lessening and slowing the damage done by age related macular
degeneration. It also has antioxidant properties, can enhance
the operation of the immune system, seems to confer some
protection against colon cancer and reduces the risk of heart
disease. Because of the mounting evidence that lutein is
effective in preventing macular degeneration and the absence of
harmful side effects, most doctors recommend increasing your
intake of lutein either through diet or with lutein supplements.
The supplement we use that includes lutein is
