Opis:
The iron diet supplements: AproFER 1000 and AproTHEM were subjected to various chemical, microbial and magnetic analysis. The microbial analysis revealed no presence of pathogenic bacteria in the studied products. No signifi cant changes in iron content or forms (bivalent/trivalent) were observed in EPR analysis of supplements stored at different conditions for a long period of time. The chemical and magnetic analysis showed that both AproFER 1000 and AproTHEM contain a high concentration of bivalent iron so they can be used as an iron diet supplements.

Opis:
The objective of this study was to determine the level of awareness concerning the knowledge of the benefits and use of ginger among students of the Nigerian Army School of Education (NASE), Sobi-Ilorin Kwara State. A descriptive survey design was used to elucidate the awareness, knowledge of benefits and practice of ginger usage. The population included all 350 students from NASE, Ilorin. They were purposively selected, with 337 participating in the study. The instrument for data collection was a validated researcher-structured questionnaire. Test retest reliability was conducted and PPMC coefficient (r=0.72) was obtained. Frequency and percentage were used for demographic data while t-test was used for testing the hypotheses at 0.05 alpha level. The result revealed that NASE, Ilorin students were highly aware of the benefits of ginger, 312 (92.6%). There was significant difference between soldiers and officers in; awareness n=337, t (335)=4.94, p<0.001, η2 .007; health benefits n=337, t (335)=2.92, p < 0.004, η2 .002 and performance purposes n=337, t (335)=2.48, p<0.001, η2 .002. It was concluded that the majority of NASE students are aware of ginger, which they mainly consumed in drinks. A further study is necessary to ascertain the size of benefits and the best way ginger usage would enhance the health and job performance of military personnel.

Opis:
Nowadays, because of irregular lifestyle, high level of stress dietary supplements (DS) are becoming more popular as a source of needful nutrients among millions of people all over the world. The main purpose of present study was to estimate prevalence of dietary supplement consumption in sport, motivation in DS usage and sources of information. Anonymous self-administered questionnaire was spread among students of medical faculty in the end of their fourth year of study. There were 218 students of the fourth year of the Medical Faculty, of which 60.1% were females and 39.9% were males. Males more often used or had been using dietary supplements than females. The most popular dietary supplement was whey protein. The most common aim among men was to build up muscle mass. It is possible to state conclusions that prevalence of using dietary supplement among students is similar to values reported previously in the literature. Males were definitely more often undertaking physical activity in the gym and that could be the reason why they were definitely more often using specific dietary supplements.

The aim of the investigation was to review experimental articles and patents referring to corn-based nutritional products for sportspeople published in the period 1970–2019. Publications were searched in the ISI Web of Science and Scopus databases, as well as the Google Scholar and Google Patents internet search engines. Factorial combinations of the keywords (“Zea mays” or “maize” or “corn”) and (“athlete” or “sport”) were applied. Most papers and patents were published in the period 2010–2019 by researchers affiliated to the USA and China – the two largest global producers of corn. Altogether, 65 patents and 16 articles were recorded. Inventors patented food supplements based on corn-derived saccharides and proteins. Empirical articles were devoted to the impact of corn-based food products on health of sportspeople, evaluation of the impact of length of consumption on the metabolism and performance of athletes, as well the frequency of use and acceptance of nutritional products based on corn by sportspeople. Despite growing interest in the application of corn constituents in nutritional products for sportspeople, further investigations are strongly desirable.

RESEARCH OBJECTIVE: Perform a review of protein and vitamin D supplementation in Sarcopenia. THE RESEARCH PROBLEM AND METHODS: Demographic change implies new demands for public health, with health promotion and prevention activities seeking to delay the appearance of common diseases in elderly population. We performed a review of protein and vitamin D supplementation in Sarcopenia. THE PROCESS OF ARGUMENTATION: Changes in body composition occur during the aging process, resulting in increased body fat and reduced muscle mass and also bone mass. Sarcopenia is defined by a syndrome characterized by generalized and progressive loss of muscle mass and strength. After 50 years, there is a reduction between approximately 1% and 2% of muscle mass per year. RESEARCH RESULTS: Currently progressive resistance training is the most well-established intervention, and dietary interventions such as protein and vitamin D also mentioned in literature. Leucine is a branched chain amino acid knows as key role in muscle protein synthesis. The consumption of leucine-enriched amino acids showed beneficial effects in the elderly contributing to the conservation of skeletal muscle mass. Vitamin D has pre-hormone functions, vitamin D deficiency is related with diffuse musculoskeletal pain, myopathy, sarcopenia and falls. Vitamin D supplementation of 800 to 1000 IU/day is associated with increased muscle strength in the elderly. CONCLUSIONS, INNOVATIONS AND RECOMMENDATIONS: The protein and vitamin D supplementation are strategies that are proving to be important for the prevention and treatment of sarcopenia, especially when associated with resistance training.

The aim of the study was to assess the dietary supplements used by amateur sportswomen training in fitness clubs (F-Fitness) compared to women who do not train (C-Control). Methods. 248 women aged 16 to 31 years (F: 120, C: 128) participated in the study. Results. In group F, 60.00% of women used protein products, 40.83% other dietary supplements, most often: creatine 17.50%, vitamin complexes 10.00%, vitamin D 10.00%, branched chain amino acids 7.50%, fish oil/omega acids 7.50%. A positive predictor of the use of protein supplements was the consumption of vegetables (B: 1.26, 95% CIs: 1.13–11.01). Total supplement use: age (B: 0.27, 95% CIs: 1.09–1.59), number of months of training (B: 0.59, 95% CIs: 1.15–2.81), following the advice of a dietitian (B: 1.50, 95% CIs: 1.45–13.87) and calorie counting (B: 1.54, 95% CIs: 1.49–14.53). Positive predictors of creatine use were: age (B: 0.54, 95% CIs: 1.21–2.42) and calorie count (B: 2.09, 95% CIs: 1.35–48.32). Conclusions. Supplements were more often used by women who were older, who did long training sessions, who were counting calories and those who were seeing a dietitian. Creatine was used more frequently by older women and women counting calories.

The aim of this study was to determine the prevalence and reasons of intake of dietary supplements among students aged 19-29 years. The survey was performed using the questionnaire method Computer-Assisted Web Interview among group of 350 students aged 19-29 years in March 2018. Dietary supplements have been used by 66,85% respondents. More than a half of respondents took them every day. Almost 70% of students took dietary supplements as a result of their own decisions. Single-component supplements were the most commonly used ones, including preparations of vitamin D and magnesium. The most common reasons of supplementation among students were preventions and improvement of health. The current study shows that the intake of dietary supplements is common among students, especially among women and students of nutritional associated courses. In most of the cases it was a result of individual decisions, rarely due to the recommendations of specialists.

Opis:
Unit packaging of dietary supplements - an inherent element of their manufacturing, without which they would be impossible to market — has numerous interlocking functions to fulfil, including the protective, transport, information, functional, ecological and marketing functions. The information function, however, is one of the priority functions of dietary supplement packaging. In the era of the continual development of online and self-service stores (including pharmacies), such packaging has become one of the key sources of information about dietary supplements' features and properties, while also serving as a brand image creator and a carrier of promotional information. This raises the questions of whether and to what extent the unit packaging of dietary supplements influences the purchasing decisions of consumers, what features and elements of such packaging are crucial for consumers in the purchasing process, and what significance supplement packaging has in the purchasing process against the background of other purchasing determinants. Seeking to address these questions, herein we present selected results of an original study conducted in 2019 with a purposely selected sample of 468 dietary supplement consumers in Poland, whose main purpose was to identify the role and significance of packaging as a determinant of purchase in relation to three selected categories of dietary supplements.

Opis:
Introduction. Recent studies have revealed an increase in the consumption of dietary supplements including frequency of use of caffeine, which is addictive and potentially harmful in higher doses. Energy drinks include high doses of caffeine and are particularly targeted at young people. Objective.The aim of the study was to investigate the frequency of use of caffeine-containing energy products, associated factors and understanding the associated side- effects in university students. Materials and method. A cross-sectional questionnaire-based survey was conducted among students of the 5 largest Universities in Krakow. Statistical significance was set at the 0.05 level. Results. Around 35% of respondents reported the use of different supplements including high doses of caffeine. Frequency of caffeine-containing products consumption was significantly higher in female students compering to males. Also, those respondents who originated from big cities were more likely to use caffeine-containing products. The study revealed that these substances were also more popular among those participants who study economics. Most students use these substances in order to reduce feeling tired and the duration of sleep, others mainly to increase concentration prior to examinations. Almost one fourth of the group who used these substances admitted to having experienced some side-effects in the past. They suffered mainly from insomnia, but also from excessive stimulation and muscle trembling. Almost half of the substances users did not know of any potential side-effects. Conclusions. Attempts should be made to increase public awareness of the side-effects of these substances, particularly among the student population. These campaigns should be targeted especially at female students who come from bigger cities. This study is a step towards drawing attention to this issue.

Background. Dietary supplements (DS) are available over the counter, but patients with impaired renal function are specifically at risk for toxicity when consuming certain DS. The aim of this study was to evaluate the prevalence and characteristics of DS use in patients with chronic kidney disease (CKD). Material and methods. A cross-sectional, controlled DS use survey (22 questions) was conducted among 180 CKD patients (stage 1-5, dialysis, kidney transplant), with 60 patients without CKD serving as controls. Results. DS use did not differ significantly between subjects with and without CKD, unless the CKD patients were on dialysis. In the CKD group, 20% admitted to use DS regularly and 22% did not take the mat all. In the controls, DS consumption was 17% and 13%, respectively (NS). The DS use was higher among women ascompared to men (89% vs. 70%; p < 0.005), and people living in cities versus those living in the country side (81% vs. 63%; p < 0.05). DS most commonly used were: vitamins, minerals, and herbs. Major indications for DS use included: musculoskeletal issues, general health improvement and prevention of urinary tract infections. Subgroup analyses revealed that dialysis patients were characterized by a significantly higher DS use in comparison to CKD stage 1-5 subjects and renal transplant recipients. The decision to introduce DS was made by the physician in 54% of cases; by a pharmacist in 9% of cases, and by the patients themselves in 37%. Only 21% of patients with CKD, and 27% of subjects without CKD, declared knowledge of any possible side-effects associated with DS (NS). Conclusions. The use of DS among patients with CKD is similar to patients without CKD, with the exception of those on dialysis. Vitamins and minerals were the most commonly reported DS consumed. The knowledge on potential side-effectof DS was limited to approximately one-fourth of those surveyed.

Opis:
Iron, zinc and copper distribution in rat tissues was studied in dependence on the dietary level of these elements and source of protein. All experimental diets had the same Fe:Zn:Cu ratio and as the amounts of these elements in the diets increased so did the Fe:Zn and Fe:Cu ratios in the liver, spleen and femur. The ratio of iron to other elements in those tissues was higher in animals fed the gluten diets than in animals on casein or casein-glulen diets.
Rosnące szczury samce były karmione przez 6 tygodni dietami zawierającymi 20% białka, którego źródłem była kazeina, gluten pszenny lub ich mieszanina (1:1). Zawartość żelaza, cynku i miedzi była zróżnicowana następująco: 50, 100 lub 300% zaleceń dla szczurów. Mimo stałego stosunku Fc:Zn:Cu w dietach i po absorbcji z przewodu pokarmowego wzrost podaży badanych składników powodował proporcjonalnie większe gromadzenie żelaza w stosunku do cynku i miedzi w wątrobie, śledzionie i kościach, miedzi w stosunku do żelaza w nerkach i cynku w stosunku do miedzi w kościach. Na diecie glutenowej, ograniczającej wzrost zwierząt, gromadzenie żelaza w wątrobie, śledzionie i kościach było proporcjonalnie większe, a w nerkach proporcjonalnie mniejsze niż w diecie kazeinowej, a w szczególności kazeinowo-glutenowej.

Choroby układu sercowo-naczyniowego należą do grupy chorób cywilizacyjnych odpowiedzialnych za główną część zgonów na świecie. W leczeniu i zapobieganiu tym chorobom stosuje się liczne leki i preparaty, w tym zawierające substancje roślinne, po które szczególnie chętnie sięgają pacjenci we wczesnych stanach chorobowych. Na rynku obecnych jest wiele preparatów roślinnych dostępnych bez recepty. Celem opracowania było sporządzenie wykazu systematycznego roślin, które są stosowane powszechnie przez pacjentów przy leczeniu i suplementacji różnych schorzeń związanych z układem krwionośnym. Na podstawie 100 preparatów dostępnych w aptekach lub sklepach zielarskich bez recepty w Polsce sporządzono wykaz gatunków roślin, które scharakteryzowano pod kątem ich pochodzenia, rodzaju surowca zielarskiego, składów chemicznych i właściwości leczniczych wykorzystywanych w chorobach krążenia. Sporządzony wykaz systematyczny obejmuje 65 gatunków, głównie roślin naczyniowych. Najbardziej powszechnym surowcem stosowanym w preparatach dostępnych na rynku jest Crataegus sp., Aesculus hippocastanum oraz Ruscus aculeatus. Większość odnotowanych tu roślin wykazuje działanie wazoprotekcyjne (np. Ginkgo biloba, Ophiogon japonicus, Ruscus aculeatus, Ribes nigrum), obniża ciśnienie tętnicze krwi (np. Aronia melanocarpa, Fucus vesiculosus, Passiflora incarnata), działa rozkurczająco (np. Leonurus cardiaca, Polygonum aviculare). Lista systematyczna obejmuje 23 gatunki roślin rodzimych dla Europy środkowej, natomiast substancje roślinne otrzymywane z 20 gatunków sprowadzane są różnych obszarów świata.

Background. Biotin levels may interfere with immunological tests that use biotin-streptavidin complexes. Although the recommended daily intake (RDI) of biotin is 30 μg, some dietary supplements that are available without prescription contain double or even tenfold the RDI. Material and methods. To asses if biotin levels influence thyroid-stimulating hormone (TSH) serum concentrations using two different methods (chemiluminescent assay [CLIA] and fluorescent immunoassay [FEIA]), 110 samples from newborns and 64 samples from pregnant women in the first trimester were collected. Participants completed a questionnaire regarding dietary supplement use. Biotin levels were determined using the ELISA technique. Results. Biotin levels for newborns were 0.004-0.170 ng/ml and for pregnant women were 0.070-0.155 ng/ml (22 women were taking supplements containing from 30 μg to 35 mg of biotin). Biotin levels were below the value of 400 ng/ml stated by the manufacturer of the CLIA method to influence TSH levels. The FEIA manufacturer does not state the influence of biotin levels in the insert. Correlation tests results between TSH value and biotin were r=-0.1 for CLIA method and r=0.04 for FEIA method. Conclusions. According to our results, TSH values are not influenced by biotin levels even if the RDI was exceeded.
Wprowadzenie. Poziomy biotyny mogą zakłócać testy immunologiczne wykorzystujące kompleksy biotyna-streptawidyna. Chociaż ZDS (zalecane dzienne spożycie) wynosi 30 μg, niektóre suplementy diety dostępne bez recepty zawierają podwójne lub nawet dziesięciokrotne wartości ZDS. Materiał i metody. Zebrano 110 próbek od noworodków i 64 próbki od ciężarnych kobiet w pierwszym trymestrze ciąży, aby ocenić, czy poziomy biotyny mogą wpływać na stężenie TSH w surowicy przy dwóch różnych metodach (CLIA i FEIA). Wykorzystano też kwestionariusz dotyczący zastosowanego suplementu diety. Poziomy biotyny określono za pomocą techniki ELISA. Wyniki. Poziom biotyny w przypadku noworodków znajdował się w przedziale 0,004-0,170 ng/ml, a w przypadku kobiet ciężarnych: 0,070-0,155 ng/ml (22 kobiety przyjmowały suplementy diety zawierające od 30 μg do 35 mg biotyny). Poziom biotyny był poniżej wartości 400 ng/ml podanej przez producenta metody CLIA, aby mógł wpłynąć na poziomy TSH. Producent FEIA nie deklaruje takiego wpływu we wkładce. Wyniki testów korelacji pomiędzy wartością TSH a biotyną wynosiły: r=-0,1 w metodzie CLIA i r=0,04 w metodzie FEIA. Wnioski. Zgodnie z wynikami, poziomy biotyny nie mają wpływu na stężenie TSH, nawet jeśli ZDS zostało przekroczone.

Opis:
Recent years have witnessed a rapid development of the dietary supplement market and a revived interest in herbal products used for therapeutic purposes. Herbs and medicinal plants have been used in traditional medicine for centuries. The concentrations of active substances in industrially processed plant extracts are many times lower than those found in the original plant material. For this reason, long-term of use herbal preparations is safe, and it dśs not require medical consultation. Herbs and medicinal plants have a complex composition, and recent research indicates that they may produce adverse reactions with food ingredients or pharmaceuticals. Molds, mainly fungi of the genera Fusarium, Penicillium and Aspergillus which colonize growing plants, are thermophilous organisms that can survive drying and heat processing, and they can find their way to the final product. Those fungi produce mycotoxins, metabolites which are toxic for humans. In our study, fungi of the genera Aspergillus and Fusarium were determined in commercially available fresh herbs, herbal teas and herbal dietary supplements in the form of tablets.
W ostatnich latach nastąpił szybki rozwój rynku suplementów diety i powrót do preparatów ziołowych stosowanych w profilaktyce i w lecznictwie. Ma to swoje uzasadnienie tym, że zioła i rośliny lecznicze były od lat stosowane z powodzeniem w medycynie tradycyjnej. Używane w przemyśle farmaceutycznym wyciągi z roślin zawierają w swoim składzie stężenia substancji aktywnych wielokrotnie niższe od tych zawartych w samych roślinach. Gwarantuje to bezpieczeństwo długotrwałego stosowania bez konsultacji z lekarzem. Jednak zioła i inne rośliny o właściwościach leczniczych mają bardzo złożony skład i coraz częściej okazuje się, że mogą łatwo reagować w sposób niekorzystny ze składnikami żywności czy innymi farmaceutykami. Dodatkowo dużym zagrożeniem okazują się grzyby pleśniowe, głównie z rodzaju Fusarium, Penicillium i Aspergillus, które kolonizują rośliny w stanie naturalnego wzrostu, a w procesie suszenia i przetwarzania ze względu na swoją termofilność przechodzą do produktu gotowego. Są one szczególnie niebezpieczne, ponieważ mają zdolność wytwarzania toksycznych dla człowieka produktów przemiany materii, mikotoksyn. Jak wynika z przeprowadzonych badań własnych, grzyby z rodzaju Aspergillus i Fusarium występują nie tylko na świeżych ziołach dostępnych w sprzedaży, ale również w herbatkach ziołowych oraz w ziołowych suplementach diety w postaci tabletek.
