It's that time of year again, when the sneezing and sniffling starts. Seasonal allergies can make life miserable for millions of people. But what if there was a natural way to lessen your symptoms? Quercetin, a flavonoid found in many plants, might be the answer. What are seasonal allergies and what causes them? Seasonal allergies, also known as allergic rhinitis, are a type of inflammation of the nose that occurs when the immune system overreacts to airborne particles such as pollen, dust, or mold spores. The most common symptoms include sneezing, runny nose, and itchy eyes. Seasonal allergies can occur at any time of year, but they are most common in spring and fall. There are a number of different factors that can contribute to seasonal allergies, including genetics, weather patterns, and air pollution. In addition, people who suffer from other conditions such as asthma or eczema are more likely to develop seasonal allergies. treatment for seasonal allergies typically involves avoiding triggers and managing symptoms with medication. In severe cases, allergy shots may be recommended. With proper management, people with seasonal allergies can enjoy symptom-free days. What is quercetin and where can it be found? Quercetin is a plant-based flavonoid that has been shown to have potent anti-inflammatory and antioxidant effects. It is found in many fruits and vegetables, including apples, onions, and berries. Quercetin supplements are also available. Studies have shown that quercetin can help to reduce the symptoms of allergies, such as hay fever and seasonal allergies. It does this by inhibiting the release of histamine, which is a chemical that triggers allergy symptoms. In addition, quercetin can help to reduce inflammation and swelling. For these reasons, it is often recommended as a natural treatment for allergies. How does quercetin work to alleviate allergy symptoms? Quercetin has a wide range of health benefits, including reducing inflammation and acting as an antioxidant. Quercetin also has the ability to block histamine, which is one of the main molecules involved in allergic reactions. When histamine is released, it causes the symptoms of allergies such as runny nose, watery eyes, and hives. By blocking histamine, quercetin can help to reduce these symptoms. In addition, quercetin can also help to reduce the production of inflammatory molecules such as cytokines. This helps to further reduce the symptoms of allergies and inflammation. How much quercetin should you take to see results? So, how much quercetin should you take to see results? Studies on quercetin supplementation have used dosages ranging from 500 mg to 1,000 mg per day to start and go up as needed. Generally, the higher doses are used to treat specific conditions, while the lower doses are more typically used for preventative purposes. Are there any other natural remedies that can help with allergies? There is no doubt that allergies can be a real nuisance, causing symptoms such as itchy eyes, sneezing, and skin rashes. While medications such as antihistamines are commonly used to manage these symptoms, there may be other natural remedies that can help as well. For instance, researchers have found that medicinal herbs such as nettle and astragalus may help to reduce inflammation associated with allergies. Additionally, changing your diet to include more antioxidant-rich foods may make you less prone to allergic reactions. Overall, while medications can be an important part of managing allergies, there are many other natural strategies that may be helpful as well. By incorporating a variety of these strategies into your treatment plan, you can hopefully minimize the impact of allergies on your life. How can you reduce your exposure to allergens in your environment? Allergens are substances that can trigger an allergic reaction in certain individuals. While different allergies manifest themselves in different ways, the main goal for anyone who is trying to reduce their exposure to allergens is to create a healthier environment for themselves and their loved ones. There are a number of tactics you can use to do this, starting with some simple steps that can be implemented at home. These include installing high-efficiency particulate air (HEPA) filters in your HVAC system, thoroughly cleaning surfaces and dusting regularly, and eliminating any indoor plants. Other steps involve avoiding exposures outside of the home, such as limiting time spent in dusty places like construction sites or opting to stay indoors on high-pollen days during allergy season. Overall, by making a few small changes to your lifestyle, you can greatly reduce your risk of exposure to allergens and take back control of your health. Can allergy medication be safely taken while taking quercetin supplements? Many people experience the unpleasant symptoms of allergies, such as a runny nose, coughing, or itchy eyes. Fortunately, there are many different medications that can help to relieve these symptoms and allow you to live a more comfortable life. However, for some people, allergy medication does not provide adequate relief. In this case, taking quercetin supplements may be an effective alternative. Additionally, some research has suggested that quercetin may actually enhance the effects of allergy medication. So is it safe to take allergy medication while taking quercetin supplements? The answer is yes, but quercetin can affect the way certain medications are absorbed by the body and should never be taken without consulting a medical professional. By doing so, you can safely reap the benefits of both treatments and enjoy a more comfortable life free from pesky allergies. The quick answer Allergy sufferers often have to contend with a host of different symptoms, from itchy eyes and a runny nose to sneezing fits and anxiety. While there are a variety of over-the-counter medications available to provide relief, many people are hesitant to take them on a regular basis due to concerns about side effects. Quercetin is a natural compound that has been shown to be effective in reducing allergy symptoms. It is generally considered safe to take quercetin along with other over-the-counter allergy medications. While there is always the potential for interactions between different substances, quercetin and most over-the-counter allergy medications are unlikely to cause any problems when taken together. As always, it is best to speak with a healthcare professional before starting any new medication regimen while consuming natural vitamin and herbal supplements.

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.

It was also shown that macular pigment density increased by an average of 5.3% after 4 weeks due to increased deposition of lutein in optical tissues.1 A second study compared the oral bioavailability of esterified lutein, the form in Best Lutein, versus non-esterified lutein in 18 human volunteers. Serum levels of lutein were measured at particular timepoints after consumption of a single dose of lutein. Researchers found that in these individuals, the lutein ester formulation was nearly 62% more bioavailable than non-esterified lutein, as determined by a higher mean area under the curve (AUC) and higher serum concentrations.2 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.

The A Team by Gregory Meade Energy Times, October 11, 2004 Want the A Team playing to improve your health? When you accumulate enough antioxidants to help you attack the molecular marauders out to mar your well-being, you improve your chances of avoiding illness. Nowadays you hear plenty of talk about the benefits of antioxidant nutrients. Antioxidants are the ammunition the body uses to fight off internal damage. They offer the body the means to fight against disease but, at the same time, your body must be in the position to use them optimally. That means getting enough sleep, consistently exercising and avoiding overly processed foods. Those lifestyle habits allow your body to garner its resources and effectively implement antioxidants in its quest for well-being. Your body has a love-hate relationship with oxidation: Can't live without it, often has trouble living with it. For instance, the production of energy in your cells requires oxidation. But the byproducts of that process, problematic molecules called free radicals, have to be chemically changed or eliminated to avoid the damage that results when they interact with other parts of the cell. Left unchecked, these molecular troublemakers can wreak havoc, oxidizing and punching holes in cell membranes and damaging other structures they contact. Antioxidant nutrients are used to defend against oxidation, quell these harmful destroyers and limit the potential harm they can cause. For a quick glimpse of one of your basic antioxidant defenses, look in the mirror. The color in your eyes represents antioxidant protection against oxidative injury from the ultraviolet rays in sunlight. Sunlight's energy sets loose free radicals every time it enters the Lenses in your eyes. Pigments absorb this radiation and, in most cases, render it harmless. As part of your vision's defenses, two of the antioxidant pigments in your food, lutein and zeaxanthin, are deposited by your body in certain areas of your eyes-in a section called the macula as well as the lens (BJ Opthalmol 1998; 82:907-10). Lutein and zeaxanthin are classified as carotenoids, chemical relatives of beta carotene, the antioxidant pigment that makes carrots orange, and lycopene, the anticancer red coloring found in tomatoes. These fat-soluble nutrients are also present in algae. In both your eyes and plants, these nutrients absorb the destructive ultraviolet rays that give birth to free radicals. Blindness Protection Studies show that consuming large amounts of these pigments lowers your risk of a common form of blindness called age-related macular degeneration (ARMD) and drops your chances of age-related cataracts. (More than 30 million people worldwide suffer from ARMD, and cataracts is the leading cause of blindness across the globe.) When the sun's rays enter the eye, lutein and zeaxanthin absorb and filter out dangerous radiation before it can injure the macula. The macula is the central part of the retina that allows us to see very fine detail. Otherwise, over time, as the macula deteriorates, our vision worsens. In addition, some researchers believe these nutrients help lower your chances of cancer. Lutein and zeaxanthin are found in spinach, Brussels sprouts, corn, collard greens, green beans, egg yolks, broccoli, cabbage, kale, lettuce, kiwi and honeydew melons. The petals of yellow flowers like marigolds and nettles are also rich in these antioxidant nutrients. Broccoli Protection You can also increase your chances of better sight as you age by consuming sulphoraphane, an antioxidant found in broccoli. Researchers at Johns Hopkins University have found that sulphoraphane takes part in the body's efforts to shield eye cells from free radicals generated by ultraviolet light (Proc Natl Acad Sci 2004; 101(28):10446-51). The researchers who performed this study believe that unlike the antioxidant nutrients vitamin C and natural vitamin E, sulphoraphane acts as an "indirect" antioxidant. That means that while those two vitamins are used by the body to directly defuse the harmful oxidative force of free radicals (and then must be replaced or regenerated in the cells), sulphoraphane acts indirectly, boosting the body's immunity defenses. Because of that indirect action, researchers point out, sulphoraphane lasts longer in the body and may produce a more profound, long-term antioxidant effect. In other laboratory tests, researchers have discovered that sulphoraphane can kill Helicobacter pylori, a bacterium recognized 20 years ago as the cause of debilitating stomach ulcers and often-fatal stomach cancers (Proc Natl Acad of Sci 5/28/02). This research shows that sulphoraphane is even effective against antibiotic-resistant Helicobacter. Adding to its benefits, sulphoraphane can help kill bacteria both inside and outside stomach cells; when this bacteria hides inside of cells it is particularly difficult to fight. " We've known for some time that sulforaphane had modest antibiotic activity," says Jed Fahey, a plant physiologist at Hopkins. "However, its potency against Helicobacter, even those strains resistant to conventional antibiotics, was a pleasant surprise." Looking for Mr. Good Diet For the biggest bang for your antioxidant buck, combine antioxidants with good lifestyle habits. A laboratory study of the heart-healthy effects of taking supplements of the antioxidant vitamins C and natural E along with L-arginine (an amino acid) found that exercise magnifies benefits (Proceedings of the National Academy of Sciences 5/24/04, online). The scientists who performed this study recommend exercise along with antioxidants to boost your nutritional advantage. The box score shows that when playing with the A Team you've got the best chance of hitting an antioxidant home run.
