Maintains Healthy Visual Function* It has been well established that lutein is present in high concentrations in the retinal tissue of the human eye. However, a study was conducted in human volunteers to determine whether taking lutein in supplement form actually increased the density of the carotenoid pigments present in the macula. In this study of eight individuals, researchers estimated the density of the macular pigments prior to having each individual take 10 mg of lutein daily in supplement form for 12 weeks. Plasma lutein concentrations were measured at 4-week intervals. During the first four weeks of the study, plasma levels increased five-fold from pre-supplement measures, and then remained at this level for the duration of the study. It was also shown that, due to increased deposition of lutein in optical tissues, macular pigment density increased by an average of 5.3% at the 4-week mark, and continued to increase until the duration of the study.1 A study was also conducted to investigate the possible role of specific nutrients in protecting the lens of the eye against aging, a risk factor for compromised visual function. The study was comprised of 376 individuals aged from 18 to 75. Of the nutrients measured, it was found that the lenses of individuals with higher concentrations of lutein and zeaxanthin showed less of an effect from the aging process. The investigators concluded that these carotenoids might play a protective role in supporting the maintenance of healthy vision.2 The Age-Related Eye Disease Study (AREDS) was a landmark study of the effects of diet and antioxidant supplementation on eye health. The study enrolled over 3500 subjects aged 55 to 80 years who were followed for approximately 6 years. Among the data collected in this multi-faceted study was a self-administered Food Frequency Questionnaire (FFQ). The AREDS Report No. 22 examined the data from the FFQs and determined that, of the nutrients evaluated, only lutein and zeaxanthin were directly related to maintaining eye health with statistical significance3. These findings corroborated similar results of an earlier multi-center study published in the Journal of the American Medical Association that also found that those with a higher intake of lutein and zeaxanthin maintained healthier eye function.4 These promising results have spurred the design of a second major clinical trial (AREDS2), which is currently enrolling participants to study the impact of supplemental xanthophylls (FloraGLO® Lutein and zeaxanthin) and other nutrients on age-related eye health.5 In addition, a double-blind placebo controlled trial was performed in ninety individuals who had signs of compromised visual function. Individuals were divided into three groups and received either 10 mg FloraGLO® lutein, 10 mg FloraGLO® lutein plus a multivitamin/multimineral formulation, or placebo for 12 months. In both the FloraGLO® lutein and FloraGLO® lutein plus other nutrients groups, improvements were seen in mean eye macular pigment optical density, visual acuity and contrast sensitivity. No improvements were noted in the placebo group.6 These results demonstrate FloraGLO® lutein’s beneficial effect on maintaining healthy visual function. Newly published research has demonstrated that lutein and zeaxanthin supplementation may enhance visual performance under glare conditions. Forty healthy subjects took daily doses of 10 mg FloraGLO® Lutein plus 2 mg zeaxanthin for six months. They were evaluated for changes in macular pigment, glare disability and photostress recovery at the onset of the study, and at 1, 2, 4 and six months. After six months, subjects experienced an average increase in macular pigment optical density (MPOD) of 39% compared to baseline, and all but two participants experienced some increase in MPOD. This increase in MPOD was also directly related to measured improvements in visual performance after exposure to bright light, as well as photostress recovery.7 This study suggests another way in which lutein and zeaxanthin can help support optimal visual function in healthy individuals. Potent Antioxidant Protection* Most of the beneficial effects of lutein are ascribed to its potent free radical scavenging abilities. It is well-known that lutein is a carotenoid related to beta-carotene and possesses antioxidant activity against a number of reactive oxygen species.8 More direct evidence for the free radical scavenging activity of lutein is found in studies of its effects on human lens epithelial cells. Cell cultures were exposed to ultraviolet light after pretreatment with lutein or alpha-tocopherol. Both nutrients were found to reduce ultraviolet-induced damage to lens epithelial cells. However, lutein was shown to have significantly higher photoprotective activity than alpha-tocopherol9 demonstrating its potential as a high-powered antioxidant. A further review of the mechanisms of lutein in conferring a protective role reveals evidence for its antioxidant activity in various body tissues. Lutein has been shown to be an effective antioxidant in vitro as well as in experimental models of a number of body systems.10 Supports Healthy Skin* A recent randomized, double blind, placebo-controlled study has demonstrated the positive effects of oral and topical administration of lutein on skin health parameters (surface lipids, hydration, photoprotective activity, skin elasticity and skin lipid peroxidation). Forty female subjects were divided into four treatment groups. Treatment options included oral administration of 5 mg of FloraGLO® Lutein twice daily or placebo and topical administration of 50 ppm FloraGLO® Lutein twice daily or placebo. Each treatment group received either an active oral treatment with a placebo topical treatment, a placebo oral treatment with an active topical treatment, both active treatments, or both placebo treatments. Statistically significant improvements were seen in all five parameters tested in all treatment groups compared to the group receiving only placebos. The greatest overall improvements were seen in the group receiving both active oral and topical treatments, while lesser but still significant improvement was seen in both the active oral only and the active topical only groups. Additionally, oral administration of lutein conferred superior photoprotective activity (as measured by skin surface redness after exposure to ultraviolet light) and prevention of lipid peroxidation (as indicated by levels of malondialdehyde in skin lipids after exposure to ultraviolet light) than either topical lutein or placebo.11 Diverse Cinical Benefits* Evidence from various experimental trials suggests that lutein may play a protective role on the circulatory and cardiovascular systems. Its antioxidant activity may also extend to the heart, skin, lungs and blood vessels, making it a nutrient with diverse clinical benefits. Lutein possesses the ability to promote the health of many body tissues.12 Suggested Adult Use: One softgel daily with food, or as directed by a health care professional.

Supplements for Children
While most parents try hard to make nutritious meals for their family, most children find the appeal of refined, fast, and junk food simply overwhelming. And, sadly, increasingly easy to buy and consume, as well. From kindergarten through 12th grade, in both grade schools and high schools, vending machines offer calorie laden candy bars, sugar-filled soft drinks, and snack foods loaded with fat and salt. Many school cafeterias actually sell fast-food to children for lunch every day. In fact, it seems almost everywhere children go and gather, visually enticing but nutritionally lacking snacks and soft drinks are sure to be available.
Determined to counteract this disturbing trend, parents everywhere are urgently seeking solutions to help their children get the nutrition they need. One answer is supplemental multivitamins. There are certainly plenty of multivitamins formulated for children currently on the market. However, these products vary considerably in quality and content. Some lack certain vital nutrients. Some taste terrible. Still others are loaded with sugar and artificial flavorings. The good news is that there are superior multivitamins and exceptional immune boosting products formulated specifically for children that actually taste great. In this issue of Ask the Doctor, we will discuss childhood nutrition and how to help ensure your children’s health with high quality, 100% natural flavored nutritional supplements.
Q. Do children really benefit from vitamin supplements? Can’t I make sure they get the vitamins and minerals they need from meals?
A. Even the most nutritionally vigilant parent cannot be 100% certain what nutrients are in the food they serve their children. That’s because there’s so much variability in the food we prepare. For instance, fat-soluble vitamins can withstand normal cooking, but vitamins A and E are gradually destroyed by exposure to air. Water-soluble vitamins such as B1, B6, folic acid, and pantothenic acid are destroyed by heat. Vitamin B2 is destroyed by light and heat, while light and air destroy vitamin C. Certain food preservatives and preparation methods also destroy the vitamins in food. To further complicate matters, some fruit and vegetables are grown and harvested in such a way that does not promote nutrient content – so even raw foods may be lacking.
Then there are those crazy food phases all children seemingly go through. While these phases are generally harmless in the long run, a recent alarming exception was in the news. A five-year old boy ate nothing but cheese pizza, Pop-tarts, biscuits, and water, refusing fruits, vegetables, juices and vitamins. He slowly developed limp, swollen gums, and small purple spots appeared on his skin. After five months of this extremely deficient diet, he was unable to walk or get out of bed because the pain was so severe. Doctors diagnosed the boy as having a severe vitamin C deficiency after ruling out other ailments such as leukemia. Within a week of getting vitamin C supplements, the boy’s pain and other symptoms were completely resolved. Obviously, this little boy’s story is unusual. However, even mild food phases (such as “If It’s Green It Must Be Yucky” or “The Only Good Crust Is A Cut-Off Crust”) can result in awfully lop-sided nutrition.
Q. Can multivitamins help my child’s performance in school?
A. Most teachers firmly believe that nutrition and learning go hand in hand. They are convinced that children who are well nourished possess the mental stamina that’s needed to learn and retain even difficult concepts. But can multivitamins help children become better students?
Two independent research teams recently conducted randomized trials to find the answer. The researchers followed 245 school-children aged 6 to 12 years for three months. They gave half of the children multivitamin tablets every day, and half of the children placebos. When the children were tested, the children in the multivitamins group showed an increase in their nonverbal intelligence scores. Nonverbal intelligence is closely associated with academic performance.
Q. I can’t get my children to take 100% natural flavored multivitamins because they don’t taste very appealing. Isn’t there some way to make a 100% natural multivitamin taste good enough for my children to willingly take?
A. Yes, there is! Because most children need chewable multivitamins, manufacturers need to contend with the truly terrible taste of certain minerals. Magnesium, iodine, copper, and iron are probably the worst tasting. Some solve this dilemma by skimping on the amounts of these minerals in their children’s formulas. Others cover up the bad taste with either massive amounts of sugar or artificial flavors, or both.
However, a select few multivitamin makers have discovered how to offer a natural flavored, great tasting children’s multivitamin that contains these vital minerals. The best children’s vitamins are prepared in a base of natural fruit that provides both antioxidants and other healthy phytonutrients. Children’s multivitamins made in such a fruit base have very low sugar content, as well, providing as little as four calories a day. Fructose – fruit sugar – is the preferred sweetening agent, in addition to the fruit content.
Q. What vitamins should be in a multivitamin for children?
A. There are several vitamins and minerals that children need to take each and every day. They include biotin, folate, niacin, pantothenic acid, vitamins B12, B1, A, B6, C, D, E, and K. Let’s review a few. We’ll start with folate, one of the B vitamins. This vital vitamin helps the body use protein, helps make DNA, helps cells grow and divide, and keeps the nervous system healthy. In fact, folate is so important to children that the Food and Drug Administration (FDA) mandated that folate must be added to many foods most children eat daily. Since 1998, cereal, enriched bread, flour corn meal, rice, and pasta have been folate-fortified with this B vitamin.
One of folate’s vital actions is the reduction of homocysteine levels in the blood. Homocysteine is an amino acid (the building block of protein) that is normally produced in the human body. Research has shown that high levels of homocysteine can irritate blood vessels, make blood clot more easily than it should, and cause blockages in arteries increasing the risk of heart attacks and strokes .
However, study after study has proven that taking folate reduces harmful homocysteine levels. While most of this research has been in adults, a recent study looked at children’s homocysteine levels. Researchers examined over 3500 children and discovered that high homocysteine levels increased the risk for heart disease in these children, especially as they grow. The researchers leading this study reinforced how critical folate is for all children.
Other critical vitamins for children are the vitamins C and E. The rates of childhood asthma have increased significantly here in the
Q. Which minerals do children need?
A. It is absolutely crucial that children get calcium, chromium, iron, magnesium, manganese, selenium, zinc, and phosphorus every day. Sadly, however, the majority of our children are not getting the recommended amounts of many of these vital minerals. Children in
According to statistics from the National Institutes of Health, only 13.5 percent of girls and 36.3 percent of boys age 12 to 19 in the
Lack of adequate calcium has immediate consequences for children, as well. The number of fractures among children and young adults has increased as a direct result of poor calcium intake. Pediatricians are also seeing children with rickets, a bone disease caused by low levels of vitamin D. Rickets became almost nonexistent after vitamin D was added to milk in the 1950s, but, due to lower milk consumption, is now appearing at greater rates around the country. And milk itself can be problematic for some children. Aside from alarming reports of hormones and herbicides in commercial dairy factory milk, even organic milk is not tolerated by all because of lactose intolerance and allergies.
Zinc is another mineral that’s vital for children. Because zinc is critical for normal growth and development, children need to take it every day. A study published in the Journal of the American Dietetic Association, however, found more than half of US children ages two to 10 years fail to get the recommended daily allowance (RDA) for zinc. What’s even more troubling is that zinc is vitally connected to children’s ability to process information, pay attention, as well as remember and retain new information
Zinc does a lot to keep children healthy. More than 200 enzymes in our bodies rely on zinc. However, it’s zinc’s ability to connect with our immune systems to help fight infections that is crucial for children. While researchers are not certain how zinc precisely boosts a child’s immunity, they think that zinc might fight pneumonia and other infections by either enhancing the body’s immune status, preventing the infection from establishing itself, or improving the immune system’s ability to rid itself of the infecting organism. It’s possible that zinc does all three.
Q. No matter what I do, my children seem to come down with bad colds each year. Besides giving them a multivitamin, are there other nutritional supplements that can keep my children healthy?
A. Absolutely! In fact, there are 100% natural flavored children’s immune formula nutritional supplements that contain their good buddy zinc, vitamins B6, C, and A (as beta carotene), plus elderberry extract. Elderberry extract has been used as a traditional medicine for hundreds of years to treat colds and flu. And as it so often happens, scientific research has validated this use. In fact, scientists have discovered that elderberry keeps viruses from invading other cells and replicating. It also spurs important immune cells into action to fight invading germs.
While we previously discussed vitamin C’s ability to help children with asthma breathe easier, it also provides powerful immune protection. It speeds up the healing of wounds, such as those knee and elbow scrapes so common in childhood. However, vitamin C is a water-soluble vitamin and can’t be stored in the body. It must be replenished every day. When children are under increased stress (like when they get sick with a cold or flu), their vitamin C levels are more rapidly depleted.
Vitamin B6 is also water-soluble and can only work in children’s bodies for eight hours. Then more B6 must be obtained. Vitamin B6 strengthens the immune system by helping white blood cells make antibodies. Vitamin A helps make lysozymes, important anti-infectious agents found in tears, saliva, and sweat. It also stimulates the thymus gland, an important immune organ, especially in children, to work better.
Q. Should children take an immune formula every day or only when they are sick?
A. It can be taken several ways. Some parents may want to give the formula when school first starts or other times that their children are exposed to lots of germs. For a child who suffers from asthma or seasonal allergies or just seems to get sick frequently, parents could provide the immune formula every day, increasing the dose when needed. And still others might feel it’s best to give their children the immune formula only whey they do catch a cold or have the flu.
No matter how it is given, the 100% all natural flavored, immune boosting nutritional supplement can provide powerful protection against all those disease-causing germs your children are exposed to every day.
Conclusion
The nutritional choices we make for our children today will have a profound effect on their health tomorrow. Recent research has revealed that diabetes, heart disease, obesity, osteoporosis, and cancer in adults often result form nutritional deficiencies that occurred in childhood.
Thankfully, the reverse is just as true. This means that children who are well nourished with an optimal intake of minerals, vitamins, and helpful herbs can grow into healthy and happy adults. Providing high quality multivitamins and immune boosting nutritional supplements for our children can be an important part of that process.

Adverse Reactions to Foods and Dietary SupplementsAnswers to common Questions The Journal of the American Medical Association reports that between 60,000 and 106,000 deaths per year in the United States are caused by prescription drugs. See JAMA, April 15, 1998 – Vol 279, No. 15. Fortunately, adverse reactions to foods and dietary supplements are far more rare than adverse reactions to drugs. However, we each consume a larger variety and quantity of foods than drugs. Because of this, and because each of us can react differently, an allergic or isolated reaction to a food or supplement is a possibility. Here’s helpful information about what to do if you or someone you care for has what appears to be an adverse reaction to a food or dietary supplement. What types of reactions could I have? The most common adverse reaction is an allergic reaction. In order to reduce the risk of an allergic reaction, carefully read all labels and buy products from reputable manufacturers who accurately disclose the ingredients in their products. If you need help finding these manufacturers, ask your local health food retailer for recommendations. How do I know what caused my reaction? Take time to carefully review what might have caused the reactions. Doctors and experts in toxicology look at several different factors in trying to determine the cause of a particular reaction. Ask yourself:
1. Is this reaction a side effect of drugs I am taking? Asking your self these questions can help limit the number of possible causes and may lead you to an answer more quickly. What should I do if I have an adverse reaction? Weather or not you know the potential cause of the reaction, follow these steps:
How can I reach the FDA or another government agency about my concerns? Various state and federal agencies employ personnel who can help respond to concerns or questions about adverse reactions. Following is contact information for some of the agencies:
How can I report an adverse event? FDA’s Center for Food Safety and Applied Nutrition (CFSAN) has an Adverse Event Reporting System (CAERS) that can be contacted in any of the following ways:
You can contact FDA’s MedWatch Program in any of the following ways: For Non-emergencies related to products purchased via internet, fill out an online form on FDA’s website at vm.cfsan.fda.gov/~dms/qa-top.html (see link to “form to report unlawful sales”) You may also contact any local poison control center, local or state health agencies, the department of Health and Human Services, the Federal Trake Commision, the Consumer Products safety Commission, or the Centers for Disease Control and Prevention, and t hey will forward your report to the FDA.
