Zeaxanthin (contained in Lutein Spray)
Lutein and Zeaxanthin were identified in 1995 as the only two Carotenoid antioxidants specific to lens and macula health. Selectively accumulated from plasma and deposited in the lens, macula, and lungs; Lutein and Zeaxanthin filter light and serve as potent free radical scavengers. The macular pigment composed of Lutein and Zeaxanthin, functions as a colour filter to protect the light-sensitive photoreceptor cells (responsible for visual acuity) from visible blue and ultraviolet light-originated free radical damage. Studies in 1997:
1. Showed a 30% reduced macular pigment density in eyes with AMD.
2. Found a correlation between reduced macular pigment density and increased lens density (cataracts) in seniors; and
3. Demonstrated that macular pigment density can be increased with dietary and/or supplemental Lutein. Maintaining sufficient levels of Lutein & Zeaxanthin (the only Carotenoid antioxidants active in the retina) can prevent ARMD and Cataracts and preserve youthful visual sensitivity.
“Most individuals supplementing with sublingual Lutein and Zeaxanthin report reduced glare and visual fatigue; improved contrast sensitivity”
Vinpocetine (vin-po-seh-teen) an extract from periwinkle seeds (vinca major) has been well researched and available in Europe for the past twenty years. Recently, it became available as a dietary supplement. Vinpocetine has been included in this formula for safer and more effective circulatory benefits to the entire retina. There are no known negative interactions with other dietary supplements or drugs.
Vinpocetine facilitates cerebral metabolism, which affects the retina and the front part of the brain. It increases blood flow, steps up the concentration of ATP (the energy carrying molecules of the cells) and thus improves utilisation of glucose and oxygen in the brain and retina. Vinpocetine also increases the turnover of Norepenephrine and Serotonin. It inhibits abnormal platelet aggregation, improves red blood cell elasticity, and inhibits an enzyme (GMP) that causes arterial constriction and blood flow reduction. Thus, arteries relax, blood pressure normalises and blood flow increases. In clinical studies, Vinpocetine has been shown to benefit depression, headaches, short-term memory, inner-ear conditions, tinnitus, vertigo, menopause, insomnia, speech impairment, stroke and eyesight disorders.
In one study, 100 predominantly atherosclerotic patients with eye disorders were given Vinpocetine. Eighty-eight subjects displayed increased retinal circulation and improved visual acuity. Half of the group that showed the best response, had conditions caused by central retinal artery insufficiency. Prior to giving Vinpocetine, dye was visible through fluorescein angiographies in the choroid only and not in the retinal arteries.
After giving Vinpocetine, dye entered the retinal arteries. The greatest improvement in circulation was seen in the macula. Functional improvements were seen in the macular region in particular.
Results were most favourable with glaucoma, macular degeneration, and diabetic retinopathy.

Another reason for more Lutein… It Prevents Cancer
Unless you’ve been living in a cave for the past five years, you probably know that eating fruits and vegetables reduces your risk for getting certain types of cancer. Scientists have been slowly unraveling the complex reasons why – primarily, it is because fruits and vegetables contain antioxidant compounds that prevent cell damage. Lutein, a Carotenoid (plant pigment) in the same chemical class as beta-carotene, is one of these compounds. Carotenoids provide the colourful palette of reds, yellows, and greens you see in vegetables and flowers, and even adorn birds, fish, and butterflies.
So what do Carotenoids have to do with your colon?
In a recent study at the University of Utah Medical School, researchers found that of all the many Carotenoids that occur in vegetables, Lutein has the strongest protective effects against colon cancer, and contributes to a better prognosis in certain cases of colon cancer.
The researchers looked at the eating habits of 1,993 patients with colon cancer and 2,410 cancer-free participants, and then used a table of food Carotenoids content to determine how much of the various types of Carotenoids each person consumed.
They weighed this information against cancer occurrence, stage, and prognosis for all study participants. The Utah team found that when a daily diet contains ample sources of Lutein – spinach, broccoli, tomatoes, oranges, celery, eggs, and lettuce and other greens are good sources – men and women are 17 percent less likely to develop colon cancer. In addition, they determined that cancer patients whose colon cancer developed before they had reached the age of 67, or whose tumours occurred further up the colon, reaped the most significant benefits from Lutein.
People in the study were between the ages of 30 and 79. The researchers were unable to draw any significant correlation between the other types of dietary Carotenoids and reduced risks of colon cancer or improved prognosis. However, these other Carotenoids have already shown their ‘colours’ in other ways.
Lycopene, known to protect eyes against age-related disease, also protects prostate cells from cancer (as does Lutein) and is found in: Red, Yellow, Orange and Green Vegetables (especially cooked or tinned tomatoes) – Eat the Rainbow!
