A total of fifteen yearling indigenous short-eared Somali goat breeds with an initial weight of 15.2 ± 0.30 kg were assigned to three treatment groups using completely randomized design. Pigeon pea (Pp) and Moringa stenopetala (MS) feeds were formulated using 0%, 5%, and 10% inclusion levels of MSLM and PPLM as experimental diets, respectively. The feed of the experiment was prepared in two levels (2 kg of Moringa stenopetala and 2 kg of pigeon pea) and was supplemented to experimental animals in treatments one and two, respectively. The average e initial body weight of selected male goats was 18.82 ± 0.37, 18.8 ± 0.37 and 17.8 ± 0.37 kg under treatment groups T1, T2 and control respectively. Data was analyzed using general linear model (GLM) procedure of SAS computer package Version 9.0 (SAS, 2002). The final weights gain (FWG) of goats on T1 and T2 of experimental group was significantly (P 0.05) the final weight gain of goat supplemented on Moringa stenopetala (T1) and pigeon pea levels (T2). The mean average weight gains (AWG) obtained from the supplemented group in this study were 7.50 ± 0.37 and 7.82 ± 0.37 kg for T1 and T2, whereas mean weight gains for un-supplemented goats were found to be 6.26 ± 0.37 kg. Feeding of dried Moringa stenopetala and pigeon pea leaves mixture improved body weights and average daily body weight gain without affecting feed intake and overall health of Somali goat breed. As Moringa stenopetala and pigeon pea leaves are rich nitrogen/protein source, they can be used effectively as substitute for conventional concentrate in the diet of growing goats at small holder farmer’s level where they can be grown in abundance. Therefore, for higher quality of forage and higher total DM yield for animal feeding, moringa should be harvested at wider harvesting intervals of at least 6th- to 8th-week intervals. Similarly, for pigeon peas, 4- to 6-week harvesting interval can result in optimum forage as well as feed quality and resulted in better growth performances for Somali short-eared goat breeds.展开更多

Unfortunately, many claims cited by supplements are unsupported and inadequately regulated. Most concerning, how ever, are the associated harmful side effects, often unrecognized by consumers. Garcinia cambogia extract and Garcinia cambogia containing products are some of the most popular dietary supplements currently marketed for weight loss. Here, we report the first known case of fulminant hepatic failure associated with this dietary supplement. One active ingredient in this supplement is hydroxycitric acid, an active ingredient also found in weight-loss supplements banned by the Food and Drug Administration in 2009 for hepatotoxicity. Heightened awareness of the dangers of dietary supplements such as Garcinia cambogia is imperative to prevent hepatoxicity and potential fulminant hepatic failure in additional patients.展开更多

Hydroxycut is a popular weight loss supplement which has previously been linked to hepatotoxicity, although the individual chemical components underlying liver injury remain poorly understood. We report two cases of acute hepatitis in the setting of Hydroxycut exposure and describe possible mechanisms of liver injury. We also comprehensively review and summarize the existing literature on commonly used weight loss supplements, and their individual components which have demon-strated potential for liver toxicity. An increased effort to screen for and educate patients and physicians about supplement-associated hepatotoxicity is warranted.展开更多

The structure and optical properties of CDs were investigated by TEM, XRD, XRF, UV-Vis, FTIR, and fluorescence spectroscopy. CDs displayed satisfactory optical pro-prieties, a high quantum yield of 23.6%, and excellent water solubility, and the particle size was 4.23-8.22 nm with an average diameter of 6.15 nm. An efficient fluorescent resonance energy transfer (FRET) between the CDs and riboflavin was achieved with CDs acting as donor and riboflavin as acceptor. A linear relationship between FRET and the riboflavin concentration from 0.10 to 3.0 μg/mL was observed, allowing the development of an accurate and fast analytical method to determine this vitamin in multivitamin/mineral supplements. Despite the potential interferences in these supplements, CDs were selective for riboflavin under optimized conditions. A paired t-test at a 95% confidence level indicated no statistically significant difference between the proposed and the reference methods. Recovery test presented values ranged from 96.0% to 101.4%. The limit of detection and relative standard deviation were estimated at 1.0 ng/mL and <2.6% (n = 3), respectively. CDs were successfully synthesized in a domestic microwave oven (1450 W, 6 min), presenting satisfactory parameters when compared with results of other studies reported in the literature, suggesting that the proposed method is a potentially useful method for the synthesis of CDs and determination of riboflavin.展开更多

Methods In 5 poor counties of Gansu, 984 children aged 6-12 months were enrolled and divided into two groups. In addition to the usual home-made complementary food, all the children were fed one sachet of either Formula Ⅰ or Formula Ⅱ supplements each day. Protein and micronutrients were provided in Formula Ⅰ, while the same energy intake was secured in Formula Ⅱ as in Formula Ⅰ. A massive dose of vitamin A was supplemented to all the children every 6 months. Hemoglobin test was done at the same time. Results Prevalence of anemia was about 35% in both Formula Ⅰ and Formula Ⅱ group at baseline, and there were no differences in hemoglobin concentration between the two groups, During the 6-month and 12-month supplementation, hemoglobin of children in Formula Ⅰ group was higher than that in Formula Ⅱ group （P〈0.05）, and hemoglobin increase in Formula Ⅰ group was significantly higher than that in Formula Ⅱ group （P〈0.001）. After 6- and 12-mouth supplementation, the prevalence of anemia in Formula Ⅰ group dropped to 19.1% and 8.2% respectively, and it was 28.0% and 12.4% in Formula 2 group. The prevalence of anemia in Formula Ⅰ group was significantly lower than that in Formula Ⅱ group （P〈0.05）. After adjusting age and hemoglobin level at baseline, the hemoglobin increase at age of 24 months in formula 1 group was higher （10.7 g/L vs 7.9 g/L, P〈0.0001）. Conclusion Micronutrient fortified complementary food supplements, with large-dose vitamin A, is effective for children aged 6-12 months in terms of iron deficiency prevention.展开更多

These case reports may substantially undercount the true magnitude of harm. Based on the past experience with harmful dietary supplements, US regulators should assume the more precautionary approach favored by Canada and Europe. Lacking effective adverse event surveillance for supplements, or the requirements to prove safety prior to coming to the market, case reports such as those summarized here assume added importance.展开更多

Nerve gap injuries resulting from neurodegeneration and trauma, such as car accidents and battlefield wounds, affect hun- dreds of thousands of people annually. Motivated by suboptimal results obtained with the current gold standard of autologous grafting （i.e., autografts）, various commercially available NGCs composed of synthetic and biomaterials are now alternatively available （Jia et al., 2014; Jones et al., 2016）.展开更多

In China, the incidence of primary osteoporosis is as high as 50%-70% in 60-69 years old females and approximately 30% in 60-69 years old males[21, which is closely related with the low intake of calcium. According to the nationwide nutrition and health survey in 2002 in China, the average daily calcium intake of Chinese residents is 391 mg, accounting for 41% of the recommended calcium intake.展开更多

Trials used to determine product safety and effectiveness, meanwhile,tend to be small, of short duration, and frequently lack financial conflict of interest disclosures. These factors could conspire to place consumers at risk, especially when published research cited in advertising cloaks products with the suggestion that their safety and effectiveness have been proven by science. Examples of current and former weight loss products backed by potentially con? icted or low quality research include Metabolife-356, Hydroxycut, Xenadrine and LeptiCore. Published research, especially in the field of weight loss supplements, needs better conflict of interest disclosure, and regulators should consider how research f indings are used in marketing claims.展开更多

About 4%-12% of women are currently estimated to have this condition. It is hypothesized that PCOS appears in women who have long-standing insulin resistance （1R）, which leads to high androgen and testosterone levels; this ultimately disrupts their menstrual cycles. Some researchers attribute IR to genetic factors, although there have been only minute changes in the human genome in the past 20 000 years. However, even with a stable gene pool, genes can be turned on and offby the environment, food and air quality and toxin exposure.展开更多

The methods were validated in terms of linearity, limits of detection (LOD), limits of quantification (LOQ), precision, and recovery by using vitamin standards and a reference material SRM 3280 (multivitamin/multimineral tablets) obtained from the National Institute of Standards and Technology (NIST). A total of 22 samples of vitamin supplements, randomly acquired in local markets of Sao Paulo (Brazil) were evaluated for content of vitamin C by these two methodologies. The precision expressed as RSD was lower than 5% for both methods. LOD was 3.6 μg/mL for HPLC and 1.0 mg for titration, while LOQ were 12.0 μg/mL and 3.0 mg for HPLC and titration, respectively. Percent recoveries (%) of spiked samples ranged from 98.7 to 100.5 for HPLC and from 98 to 104 for titration. The contents of vitamin C in SRM 3280 (Certified value = 42.2 ± 3.7 mg/g) were 40.2 and 42.1 mg/g when determined by HPLC and titration respectively. Statistically, there was no difference in the analysed vitamin C content for half of the samples, irrespective of the method applied. HPLC was more sensitive, but the titrimetric method was faster and consumed less reagent. Although both methods were accurate in determining the vitamin C content in SRM 3280, the matrix constituents of some vitamin supplements may have interfered with the analysis.展开更多

This study investigated the diet, including fortified foods and food supplements, of urban pregnant women and analyzed the intake of calcium, iron,and zinc to assess the corresponding contributions of fortified foods, food supplements, and the base diet. The results demonstrated that the base diet was the major source of calcium, iron, and zinc, and was recommended to be the first choice for micronutrients intake. Furthermore, consumption of fortified foods and food supplements offered effective approaches to improve the dietary intake of calcium, iron, and zinc in Chinese urban pregnant women.展开更多

Some reports suggest that their use might be responsible for excessive nutrient intake. The purpose of this survey was to examine the quantitative mineral intakes from food supplements: whether the tolerable upper intake levels (ULs) with supplements alone, or in combination with food was exceeded was checked. Methods: The survey was carried out by the Association for Consumer Research, Nürnberg, Germany. Anonymous data of 1070 supplement users (40.8% men, 59.2% women) aged 18 - 93 years were available. Three groups were examined based on dietary and supplemental mineral intakes: average, middle-high and high intake. Results: The mean number of supplements reported was 1.6 ± 1.1 products in men and 1.5 ± 0.9 products in women. The minerals most frequently consumed were magnesium, followed by calcium, zinc and selenium. The percentage of the supplement users with total intakes greater than the UL was minimal for all minerals. Supplement use in 143 cases increased the likelihood of intakes above the UL only for magnesium. Subjects particularly in the high intake group—as a worst case scenario—had intakes above the UL in the case of calcium (n = 23) and zinc (n = 34). The percentage of subjects taking several products was greater in subjects exceeding the UL than in those below (P < 0.001). Multiple use was seen significantly more often in men than in women (P < 0.01). Conclusions: In this survey, supplement use was generally not associated with excessive intake. Supplement use resulted in intakes above the UL in only a few cases relating to magnesium, calcium and zinc. This applies more often to elderly subjects and particularly to those who already have a high mineral intake from food in the model calculation.展开更多

文摘Commercial dietary supplements are marketed as a panacea for the morbidly obese seeking sustainable weight-loss. Unfortunately, many claims cited by supplements are unsupported and inadequately regulated. Most concerning, how ever, are the associated harmful side effects, often unrecognized by consumers. Garcinia cambogia extract and Garcinia cambogia containing products are some of the most popular dietary supplements currently marketed for weight loss. Here, we report the first known case of fulminant hepatic failure associated with this dietary supplement. One active ingredient in this supplement is hydroxycitric acid, an active ingredient also found in weight-loss supplements banned by the Food and Drug Administration in 2009 for hepatotoxicity. Heightened awareness of the dangers of dietary supplements such as Garcinia cambogia is imperative to prevent hepatoxicity and potential fulminant hepatic failure in additional patients.
文摘BACKGROUND Drug-induced liver injury(DILI)and herbal/dietary supplements(HDS)related liver injury present unique diagnostic challenges.Collaboration between the clinician and the pathologist is required for an accurate diagnosis and management.AIM To report our experience on the clinical-pathological findings of hepatic injury caused by drugs/HDS.METHODS A retrospective review of clinically proven cases of DILI/HDS who presented to our institution from January 1,2013 to December 31,2017 was performed.Slides were reviewed for histopathological patterns of injury and correlated with the causative agent.Out of 600 patients presenting with unexplained rise in liver enzymes undergoing biopsy,107 were suspected to have DILI/HDS.Of these,53 had a directly linked exposure to drug/herbal supplements.Fifteen patients were excluded for concurrent known liver disease.Thirty-eight patients with clinically proven DILI/HDS were finally included.RESULTS Thirty-eight cases of DILI/HDS with a male:female of 1:1.5 and mean age of 51±3 years were identified.DILI was identified in 84.2%cases while HDS injury in 15.8%.Acute hepatitis(42.1%)was the most common pattern of injury while granulomatous hepatitis(2.6%)was the least common.We found one case of acute-cholestasis due to rivaroxaban and two cases of cholestatic-hepatitis due to rizatriptan and trimethobenzamide-hydrochloride that,to the best of our knowledge,have not been previously reported.One case of steatohepatitis due to trimethoprim-sulfamethoxazole and three unusual cases of cholestatic-hepatitis with bile duct injury and steatosis due to dronedarone,C4-Extreme and hydroxycut,were also seen.Of our cohort,81.6%of the patients fared well with discontinuation of drug and 18.4%underwent transplant;of which 42.9%were deceased.CONCLUSION We describe the clinical findings,histopathological patterns of injury and clinical outcomes caused by drugs.In particular,we report a few previously unreported/rarely observed clinical and histopathological patterns of hepatic injury.
文摘Dietary supplements represent an increasingly common source of drug-induced liver injury. Hydroxycut is a popular weight loss supplement which has previously been linked to hepatotoxicity, although the individual chemical components underlying liver injury remain poorly understood. We report two cases of acute hepatitis in the setting of Hydroxycut exposure and describe possible mechanisms of liver injury. We also comprehensively review and summarize the existing literature on commonly used weight loss supplements, and their individual components which have demon-strated potential for liver toxicity. An increased effort to screen for and educate patients and physicians about supplement-associated hepatotoxicity is warranted.
文摘Vascular biology,endothelial and vascular smooth muscle and cardiac dysfunction play a primary role in the initiation and perpetuation of hypertension,cardiovascular disease and target organ damage.Nutrientgene interactions and epigenetics are predominant factors in promoting beneficial or detrimental effects in cardiovascular health and hypertension.Macronutrients and micronutrients can prevent,control and treat hypertension through numerous mechanisms related to vascular biology.Oxidative stress,inflammation and autoimmune dysfunction initiate and propagate hypertension and cardiovascular disease.There is a role for the selected use of single and component nutraceutical supplements,vitamins,antioxidants and minerals in the treatment of hypertension based on scientifically controlled studies which complement optimal nutrition,coupled with other lifestyle modifications.
文摘In this work, lemon and onion biomasses commonly found in street markets are for the first time used to develop a facile, fast and low-cost one-step microwave-assisted carbonization method for synthesis of highly fluorescent carbon dots (CDs). The structure and optical properties of CDs were investigated by TEM, XRD, XRF, UV-Vis, FTIR, and fluorescence spectroscopy. CDs displayed satisfactory optical pro-prieties, a high quantum yield of 23.6%, and excellent water solubility, and the particle size was 4.23-8.22 nm with an average diameter of 6.15 nm. An efficient fluorescent resonance energy transfer (FRET) between the CDs and riboflavin was achieved with CDs acting as donor and riboflavin as acceptor. A linear relationship between FRET and the riboflavin concentration from 0.10 to 3.0 μg/mL was observed, allowing the development of an accurate and fast analytical method to determine this vitamin in multivitamin/mineral supplements. Despite the potential interferences in these supplements, CDs were selective for riboflavin under optimized conditions. A paired t-test at a 95% confidence level indicated no statistically significant difference between the proposed and the reference methods. Recovery test presented values ranged from 96.0% to 101.4%. The limit of detection and relative standard deviation were estimated at 1.0 ng/mL and <2.6% (n = 3), respectively. CDs were successfully synthesized in a domestic microwave oven (1450 W, 6 min), presenting satisfactory parameters when compared with results of other studies reported in the literature, suggesting that the proposed method is a potentially useful method for the synthesis of CDs and determination of riboflavin.
文摘Herbal and dietary supplements(HDS)are increasingly used worldwide for numerous,mainly unproven health benefits.The HDS industry is poorly regulated compared to prescription medicines and most products are easily obtainable.Drug induced liver injury(DILI)is a well-recognized entity associated with prescription and over the counter medications and many reports have emerged of potential HDS-related DILI.There is considerable geographic variability in the risk and severity of DILI associated with HDS but the presentation of severe liver injury is similar with a hepatocellular pattern accompanied by jaundice.This type of injury can lead to acute liver failure and the need for liver transplantation.Patients will often fail to mention their use of HDS,considering it natural and therefore harmless.Hence physicians should understand that these products can be associated with DILI and explicitly ask about HDS use in any patient with otherwise unexplained acute liver injury.
文摘Objective To assess the effectiveness of complementary food supplements with protein and multi-micronutrients on hemoglobin and anemia in infants and young children. Methods In 5 poor counties of Gansu, 984 children aged 6-12 months were enrolled and divided into two groups. In addition to the usual home-made complementary food, all the children were fed one sachet of either Formula Ⅰ or Formula Ⅱ supplements each day. Protein and micronutrients were provided in Formula Ⅰ, while the same energy intake was secured in Formula Ⅱ as in Formula Ⅰ. A massive dose of vitamin A was supplemented to all the children every 6 months. Hemoglobin test was done at the same time. Results Prevalence of anemia was about 35% in both Formula Ⅰ and Formula Ⅱ group at baseline, and there were no differences in hemoglobin concentration between the two groups, During the 6-month and 12-month supplementation, hemoglobin of children in Formula Ⅰ group was higher than that in Formula Ⅱ group （P〈0.05）, and hemoglobin increase in Formula Ⅰ group was significantly higher than that in Formula Ⅱ group （P〈0.001）. After 6- and 12-mouth supplementation, the prevalence of anemia in Formula Ⅰ group dropped to 19.1% and 8.2% respectively, and it was 28.0% and 12.4% in Formula 2 group. The prevalence of anemia in Formula Ⅰ group was significantly lower than that in Formula Ⅱ group （P〈0.05）. After adjusting age and hemoglobin level at baseline, the hemoglobin increase at age of 24 months in formula 1 group was higher （10.7 g/L vs 7.9 g/L, P〈0.0001）. Conclusion Micronutrient fortified complementary food supplements, with large-dose vitamin A, is effective for children aged 6-12 months in terms of iron deficiency prevention.
文摘There is a growing number of case reports of hepatoxicity from the widely marketed weight-loss supplement Hydroxycut, which contains the botanical ingredient Garcinia cambogia . These case reports may substantially undercount the true magnitude of harm. Based on the past experience with harmful dietary supplements, US regulators should assume the more precautionary approach favored by Canada and Europe. Lacking effective adverse event surveillance for supplements, or the requirements to prove safety prior to coming to the market, case reports such as those summarized here assume added importance.

文摘Nerve guidance channels for peripheral nerve injury： Over the past decade, nerve guidance channels （NGCs） have emerged as a promising technology for regenerating gap injuries in peripheral nerves. Nerve gap injuries resulting from neurodegeneration and trauma, such as car accidents and battlefield wounds, affect hun- dreds of thousands of people annually. Motivated by suboptimal results obtained with the current gold standard of autologous grafting （i.e., autografts）, various commercially available NGCs composed of synthetic and biomaterials are now alternatively available （Jia et al., 2014; Jones et al., 2016）.
文摘Osteoporosis, characterized by loss of bone mass and microarchitectural deterioration of bone tissue, results in enhanced bone fragility and increases risk of fractureIll. In China, the incidence of primary osteoporosis is as high as 50%-70% in 60-69 years old females and approximately 30% in 60-69 years old males[21, which is closely related with the low intake of calcium. According to the nationwide nutrition and health survey in 2002 in China, the average daily calcium intake of Chinese residents is 391 mg, accounting for 41% of the recommended calcium intake.

文摘Weight loss supplements often contain powerful pharmacoactive ingredients with the potential to cause harm. Trials used to determine product safety and effectiveness, meanwhile,tend to be small, of short duration, and frequently lack financial conflict of interest disclosures. These factors could conspire to place consumers at risk, especially when published research cited in advertising cloaks products with the suggestion that their safety and effectiveness have been proven by science. Examples of current and former weight loss products backed by potentially con? icted or low quality research include Metabolife-356, Hydroxycut, Xenadrine and LeptiCore. Published research, especially in the field of weight loss supplements, needs better conflict of interest disclosure, and regulators should consider how research f indings are used in marketing claims.
文摘Patients with a diagnosis of polycystic ovary syndrome （PCOS） are on the rise. About 4%-12% of women are currently estimated to have this condition. It is hypothesized that PCOS appears in women who have long-standing insulin resistance （1R）, which leads to high androgen and testosterone levels; this ultimately disrupts their menstrual cycles. Some researchers attribute IR to genetic factors, although there have been only minute changes in the human genome in the past 20 000 years. However, even with a stable gene pool, genes can be turned on and offby the environment, food and air quality and toxin exposure.
文摘Herein, the iodometric titration and HPLC-RP methods were compared for the determination of vitamin C in vitamin and mineral supplements. The methods were validated in terms of linearity, limits of detection (LOD), limits of quantification (LOQ), precision, and recovery by using vitamin standards and a reference material SRM 3280 (multivitamin/multimineral tablets) obtained from the National Institute of Standards and Technology (NIST). A total of 22 samples of vitamin supplements, randomly acquired in local markets of Sao Paulo (Brazil) were evaluated for content of vitamin C by these two methodologies. The precision expressed as RSD was lower than 5% for both methods. LOD was 3.6 μg/mL for HPLC and 1.0 mg for titration, while LOQ were 12.0 μg/mL and 3.0 mg for HPLC and titration, respectively. Percent recoveries (%) of spiked samples ranged from 98.7 to 100.5 for HPLC and from 98 to 104 for titration. The contents of vitamin C in SRM 3280 (Certified value = 42.2 ± 3.7 mg/g) were 40.2 and 42.1 mg/g when determined by HPLC and titration respectively. Statistically, there was no difference in the analysed vitamin C content for half of the samples, irrespective of the method applied. HPLC was more sensitive, but the titrimetric method was faster and consumed less reagent. Although both methods were accurate in determining the vitamin C content in SRM 3280, the matrix constituents of some vitamin supplements may have interfered with the analysis.

文摘Objective:To identify the anti-inflammatory activity through two murine models and in the median Lethal Dose(LD_(50)) of three dietary supplements that contain Moussonia deppeana.Methods:The anti-inflammatory activity of three dietary supplements(Cicatrisan/Gastricus^(R),Gastinol^(R),and Gastrovita^(R)) EtOH extracts was evaluated by TPA and by carrageenan murine models;also,median Lethal Dose(LD_(50)) was determined.Verbascoside was quantified by High-Performance Liquid Chromatography.β-sitosterol,stigmasterol and the mixture of ursolic and oleanolic acids were identified in all supplements by TLC;however,none of these dietary supplements contain verbascoside.Results:For the TPA model,Cicatrisan/Gastricus^(R)generated a notable effect with 38.24%inhibition.While in the carrageenan model,it also exhibited noteworthy anti-inflammatory activity of ear edema with 66.39%of paw edema inhibition at 150 mg/kg,followed by Gastinol^(R) and Gastrovita^(R) with 50%at 300 mg/kg.Finally,LD_(50) was >2 g/kg for all supplements,when was administered intragastrically and Body Weight(BW) gain in mice was not altered after 14 days.Conclusions:Of the three food supplements containing M.deppeana,only the EtOH extract from the Cicatrisan/Gastricus^(R)formulation(tablets) showed significant anti-inflammatory activity in both experimental models and the LD_(50) was > 2 g/kg.
文摘In the Chinese national nutrition surveys, fortified foods were not investigated separately from the base diet, and the contribution of fortified foods to micronutrients intake is not very clear. This study investigated the diet, including fortified foods and food supplements, of urban pregnant women and analyzed the intake of calcium, iron,and zinc to assess the corresponding contributions of fortified foods, food supplements, and the base diet. The results demonstrated that the base diet was the major source of calcium, iron, and zinc, and was recommended to be the first choice for micronutrients intake. Furthermore, consumption of fortified foods and food supplements offered effective approaches to improve the dietary intake of calcium, iron, and zinc in Chinese urban pregnant women.
文摘Introduction: Studies indicate that 17.9% - 60% of adults in Germany and Europe regularly use food supplements. Some reports suggest that their use might be responsible for excessive nutrient intake. The purpose of this survey was to examine the quantitative mineral intakes from food supplements: whether the tolerable upper intake levels (ULs) with supplements alone, or in combination with food was exceeded was checked. Methods: The survey was carried out by the Association for Consumer Research, Nürnberg, Germany. Anonymous data of 1070 supplement users (40.8% men, 59.2% women) aged 18 - 93 years were available. Three groups were examined based on dietary and supplemental mineral intakes: average, middle-high and high intake. Results: The mean number of supplements reported was 1.6 ± 1.1 products in men and 1.5 ± 0.9 products in women. The minerals most frequently consumed were magnesium, followed by calcium, zinc and selenium. The percentage of the supplement users with total intakes greater than the UL was minimal for all minerals. Supplement use in 143 cases increased the likelihood of intakes above the UL only for magnesium. Subjects particularly in the high intake group—as a worst case scenario—had intakes above the UL in the case of calcium (n = 23) and zinc (n = 34). The percentage of subjects taking several products was greater in subjects exceeding the UL than in those below (P < 0.001). Multiple use was seen significantly more often in men than in women (P < 0.01). Conclusions: In this survey, supplement use was generally not associated with excessive intake. Supplement use resulted in intakes above the UL in only a few cases relating to magnesium, calcium and zinc. This applies more often to elderly subjects and particularly to those who already have a high mineral intake from food in the model calculation.
