New Research Supports Antioxidants, Carotenoids & Vitamins For Helping To Maintain Eye Health

A daily supplement of Lutein in combination with Vitamin A may
slow vision loss associated with retinitis pigmentosa, according
to the results of a randomized, controlled, double-blind trial.

Writing in the Archives of Ophthalmology, American scientists now report that a daily supplement containing 12 milligrams of Lutein in combination with 15,000 International Units of Vitamin A is associated with a preservation of mid-peripheral vision. Rentinitis pigmentosa is a group of inherited eye diseases that affect the retina. It causes the degeneration of photoreceptor cells in the retina, bringing progressive vision loss to about one in 4,000 people worldwide. Previous studies had found that taking vitamin A slows the decline in retinal function and vision loss.

The new data indicates that 40 year olds with the condition who take
the Vitamin A plus Lutein combination would not be expected to lose
their mid-peripheral field until the age of 61, which would represent a
significant improvement compared with only 51 in people not taking
nutritional supplements.

Lutein Is a Key Nutrient for Eyes…
Lutein, a nutrient found in various foods including green leafy
vegetables and egg yolk, has a ten-year history in the dietary
supplement market as a nutrient to reduce the risk of age related
macular degeneration (ADM). It is often used in combination with
zeaxanthin and other antioxidant nutrients.

Researchers from the Massachusetts Eye and Ear Infirmary
recruited 225 non-smoking people with retinitis pigmentosa aged
between 18 and 60. The participants were randomly assigned to
receive Vitamin A only (15,000 IU, retinyl palmitate) or Vitamin A plus Lutein (12 mg per day) for four years. While no significant effect was observed for the overall decline in vision between the two groups, a significant reduction in the rate of vision loss in the mid-peripheral region was observed.

According to the researchers, the average level of mid-peripheral sensitivity for a patient aged 40 years is 375 dB. People taking the Lutein supplements lost on average 27 dB per year, while the other group lost 34 dB per year, noted the researchers.

No Safety Concerns For The Supplement…
No toxicity concerns were recorded during the study, and the
researchers noted that only non-smokers took part in their study.
“Follow-up of patients taking Lutein and Vitamin A with an oily fish diet for at least 10 years would be needed to confirm these estimates with respect to preserving midperipheral visual field,” concluded the researchers.

Poison Control Center: Wide Margin Of Safety Confirmed For Supplement​s

Poison Control Centers’ New Data Implies Supplements are SafeMulti-Vitamin Alive

New data has been released regarding the 28th Annual Report of the American Association of Poison Control Centers.

The report, which is a collection of data from 2010 that was reported through the Poison Control Centers’ National Poison Data System (NPDS), shows that there is a “wide margin of safety for dietary supplements.”

The study from the National Institute of Health, Office of Dietary supplements with  approx 20,000 participants showed that about 50 percent of Americans use supplements, and about 20 percent of the participating adults are taking a health supplement with at least one botanical.

The results of the study were published in the Journal of Nutrition.

The Poison Control Center has kept detailed records and statistics on the reports of poisonings for every kind of substance, which includes dietary supplements.

In 2007, the Poison Control Center reported no deaths associated with multiple vitamins, B vitamins or from vitamins A, C, D or E. It also reported that there were no deaths from any of these vitamin supplements or any other vitamin in 2010.

“The results from the 28th Annual Report of the American Association of Poison Control Centers, is a welcomed response to some of the negative press on supplements recently,” industry leaders said. “This news is both positive and reassuring of our efforts to help people become healthier.” and added “Although this report shows the overall safety of the dietary supplement industry as a whole, it is very important to try to take these results in context.”
