concomitant use of Dietary Supplements and medicines in patients due to miscommunication with physicians in japan
Nutrients, 2015Co-Authors: Tsuyoshi Chiba, Sachina Suzuki, Yoko Sato, Keizo UmegakiAbstract:We previously reported that some patients used Dietary Supplements with their medication without consulting with physicians. Dietary Supplements and medicines may interact with each other when used concomitantly, resulting in health problems. An Internet survey was conducted on 2109 people who concomitantly took Dietary Supplements and medicines in order to address Dietary supplement usage in people who regularly take medicines in Japan. A total of 1508 patients (two admitted patients and 1506 ambulatory patients) and 601 non-patients, who were not consulting with physicians, participated in this study. Purpose for Dietary supplement use was different among ages. Dietary Supplements were used to treat diseases in 4.0% of non-patients and 11.9% of patients, while 10.8% of patients used Dietary Supplements to treat the same diseases as their medication. However, 70.3% of patients did not declare Dietary supplement use to their physicians or pharmacists because they considered the concomitant use of Dietary Supplements and medicines to be safe. A total of 8.4% of all subjects realized the potential for adverse effects associated with Dietary Supplements. The incidence of adverse events was higher in patients who used Dietary Supplements to treat their disease. Communication between patients and physicians is important for avoiding the adverse effects associated with the concomitant use of Dietary Supplements and medicines.

inappropriate usage of Dietary Supplements in patients by miscommunication with physicians in japan
Nutrients, 2014Co-Authors: Tsuyoshi Chiba, Kunihiko Yokotani, Tomoko Nakanishi, Sachina Suzuki, Yoko Sato, Keizo UmegakiAbstract:Recently, people have used Dietary Supplements not only for nutritional supplementation, but also for treatment of their diseases. However, use of Dietary Supplements to treat diseases, especially with medications, may cause health problems in patients. In this study, we investigated use of Dietary Supplements in patients in Japan. This survey was conducted from January to December 2012, and was completed by 2732 people, including 599 admitted patients, 1154 ambulatory patients, and 979 healthy subjects who attended a seminar about Dietary Supplements. At the time of the questionnaire, 20.4% of admitted patients, 39.1% of ambulatory patients, and 30.7% of healthy subjects were using Dietary Supplements, which including vitamin/mineral Supplements, herbal extracts, its ingredients, or food for specified health uses. The primary purpose for use in all groups was health maintenance, whereas 3.7% of healthy subjects, 10.0% of ambulatory patients, and 13.2% of admitted patients used Dietary Supplements to treat diseases. In addition, 17.7% of admitted patients and 36.8% of ambulatory patients were using Dietary Supplements concomitantly with their medications. However, among both admitted patients and ambulatory patients, almost 70% did not mention Dietary supplement use to their physicians. Overall, 3.3% of all subjects realized adverse effects associated with Dietary Supplements. Communication between patients and physicians is important to avoid health problems associated with the use of Dietary Supplements.

why us children use Dietary Supplements
Pediatric Research, 2013Co-Authors: Regan L Bailey, Jaime J Gahche, Paul R Thomas, Johanna T. DwyerAbstract:Dietary Supplements are used by one-third of children. We examined motivations for supplement use in children, the types of products used by motivations, and the role of physicians and health care practitioners in guiding choices about Supplements. We examined motivations for Dietary supplement use reported for children (from birth to 19 y of age; n = 8,245) using the National Health and Nutrition Examination Survey 2007–2010. Dietary Supplements were used by 31% of children; many different reasons were given as follows: to “improve overall health” (41%), to “maintain health” (37%), for “supplementing the diet” (23%), to “prevent health problems” (20%), and to “boost immunity” (14%). Most children (~90%) who use Dietary Supplements use a multivitamin–mineral or multivitamin product. Supplement users tend to be non-Hispanic white, have higher family incomes, report more physical activity, and have health insurance. Only a small group of Supplements used by children (15%) were based on the recommendation of a physician or other health care provider. Most Supplements used by children are not under the recommendation of a health care provider. The most common reasons for use of Supplements in children are for health promotion, yet little scientific data support this notion in nutrient-replete children.

Dietary Supplements in Weight Reduction
Journal of the American Dietetic Association, 2005Co-Authors: Johanna T. Dwyer, David B. Allison, Paul M. CoatesAbstract:Abstract We summarize evidence on the role of Dietary Supplements in weight reduction, with particular attention to their safety and benefits. Dietary Supplements are used for two purposes in weight reduction: (a) providing nutrients that may be inadequate in calorie-restricted diets and (b) for their potential benefits in stimulating weight loss. The goal in planning weight-reduction diets is that total intake from food and Supplements should meet recommended Dietary allowance/adequate intake levels without greatly exceeding them for all nutrients, except energy. If nutrient amounts from food sources in the reducing diet fall short, Dietary Supplements containing a single nutrient/element or a multivitamin-mineral combination may be helpful. On hypocaloric diets, the addition of Dietary Supplements providing nutrients at a level equal to or below recommended Dietary allowance/adequate intake levels or 100% daily value, as stated in a supplement's facts box on the label, may help dieters to achieve nutrient adequacy and maintain electrolyte balance while avoiding the risk of excessive nutrient intakes. Many botanical and other types of Dietary Supplements are purported to be useful for stimulating or enhancing weight loss. Evidence of their efficacy in stimulating weight loss is inconclusive at present. Although there are few examples of safety concerns related to products that are legal and on the market for this purpose, there is also a paucity of evidence on safety for this intended use. Ephedra and ephedrine-containing Supplements, with or without caffeine, have been singled out in recent alerts from the Food and Drug Administration because of safety concerns, and use of products containing these substances cannot be recommended. Dietitians should periodically check the Food and Drug Administration Web site (http://www.cfsan.fda.gov) for updates and warnings and alert patients/clients to safety concerns. Dietetics professionals should also consult authoritative sources for new data on efficacy as it becomes available (ods.od.nih.gov).

Evaluation of heavy metals content in Dietary Supplements in Lebanon
Chemistry Central Journal, 2013Co-Authors: Samira Ibrahim Korfali, Tamer Hawi, Mohamad MrouehAbstract:Background The consumption of Dietary Supplements is widely spread and on the rise. These Dietary Supplements are generally used without prescriptions, proper counseling or any awareness of their health risk. The current study aimed at analyzing the metals in 33 samples of imported Dietary Supplements highly consumed by the Lebanese population, using 3 different techniques, to ensure the safety and increase the awareness of the citizen to benefit from these Dietary Supplements. Results Some samples had levels of metals above their maximum allowable levels (Fe: 24%, Zn: 33%, Mn: 27%, Se: 15%, Mo: 12% of samples), but did not pose any health risk because they were below permitted daily exposure limit and recommended daily allowance except for Fe in 6% of the samples. On the other hand, 34% of the samples had Cu levels above allowable limit where 18% of them were above their permitted daily exposure and recommended daily allowance. In contrast, all samples had concentration of Cr, Hg, and Pb below allowable limits and daily exposure. Whereas, 30% of analyzed samples had levels of Cd above allowable levels, and were statistically correlated with Ca, and Zn essential minerals. Similarly 62% of the samples had levels of As above allowable limits and As levels were associated with Fe and Mn essential minerals. Conclusion Dietary Supplements consumed as essential nutrients for their Ca, Zn, Fe and Mn content should be monitored for toxic metal levels due to their natural geochemical association with these essential metals to provide citizens the safe allowable amounts.
