Dietary supplements with adaptogenic effects
Izraelová, Alexandra ; Vespalcová, Milena (referee) ; Souralová Popelková, Miriam (advisor)
The aim of this thesis was to design a recipe for the dietary supplements with adaptogenic effects, production, and subsequent analysis (proteins, lipids, carbohydrates), which led to the determination of the energetic value of preparation. Adaptogenic effects are the domain of plants and fungi, known as adaptogens. Adaptogens act non-specifically to the human body - improve the overall condition of the body, accelerate healing and regenerative processes, slow degenerative processes in the body and thus the aging process. As biogenic active stimulators, they affect not only in the physical but also in mental area. Dietary supplements have been designed in three different forms - capsules, syrup, drops. The analysis was also performed in tablets of Vietnamese origin supplied by supervizor, of which entry to our market is being considered. Protein content was determined by Kjeldahl method, lipids by Soxhlet extraction, saccharides by gravimetric method. Dietary supplements were analyzed for heavy metals (Pb, Cd, Hg), and in herbal drops ethanol content was determined.

Tobolková, Blanka ; Vránová, Dana (referee) ; Zemanová, Jana (advisor)
A dietary supplement is a product that contains nutrients (e.g. vitamins, minerals, herbs, amino acids or fatty acids) intended to supplement the diet. The aim of the diploma thesis was to suggest a prescription for preparation of three types of dietary supplements which are used to reduce of climacteric symptoms, their production and determination of energetic (nutrition) value on account of detected content of proteins, fats and saccharides in dietary supplements. A part of the diploma thesis was to suggest suitable wrapping and price of prepared dietary supplements. The three dietary supplements were used for analyses, namely capsules, herb syrup and herb drops. The content of proteins was determined by Kjeldahl´s method, total fats were determined by Soxhlet extraction and saccharides were determined by titration with potassium permanganate (Bertrand´s method). Dietary supplements in form of capsules were particular analysed on content of heavy metals (lead, cadmium and arsenal). In herbal drops was in addition determined alcohol content (ethanol). There was from the measured data found out, dietary supplement in form of capsules was chosen as the product with the lowest energetic (nutrition) value.

Probiotic bacteria in pharmaceutical products
Suranová, Mária ; Vránová, Dana (referee) ; Veselá, Mária (advisor)
Probiotics are live microorganisms, that when administered in adequate amount confer a health benefit on the host. They are used as part of specific milk products and either as dietary supplements in form of tablets, capsules, coated pills and sirups. The most famous probiotic microorganisms are bacteria of Lactobacillus and Bifidobacterium genus, that belong in group of lactic acid bacteria. For the assessment of probiotic preparations is used broad range of methods for the microbial analysis of foods. These methods can be separated on quantitative, that enumerate amount of microorganisms in product and qualitative, that are capable detect presence or absence of certain microorganisms. Both types of the methods have large importance in control of the efficiency probiotic preparations.

Food supplements and iodine supplementation in pregnancy
VAVROUŠKOVÁ, Edita
Iodine is a trace element tremendously important for thyroid gland hormone production. It affects normal evolution of brain, especially in the time of intrauterine development and in the first year of child's life. Deficiency of iodine can lead to creation of pregnancy goiter, it also decrease the probability of carrying fetus to term and increase the probability of disorder in psycho-motoric evolution of child. Czech Republic is geographically lined up among the regions with lack of iodine in natural sources and food. However, nowadays the iodine deficiency is considered to be managed. But risk groups of population still exists, especially pregnant women can be endangered by lack of iodine, because the need of iodine intake in pregnancy increases to 200 250 ug per day and this level must be ensured. Consumption of food rich in iodine can cover the increased need of iodine. Significant source of iodine is milk and milk products. Another source is table salt enriched with iodine, but its daily intake is limited. Rich sources of iodine like sea fish, sea products and seaweed rarely occur in our diet. The goal of thesis was to evaluate intake of dietary supplements with iodine by pregnant women and evaluate women's awareness of higher iodine need and iodine food sources. Quantitative research in form of questionnaires was chosen for getting information from higher number of individuals. The questionnaire consists of 15 questions. Answers were gained from 118 respondents living in Central Bohemia, Moravia-Silesia region, Liberec region, region Highlands and South Bohemia. Questionnaire was distributed to gynecological ambulances by employees of State health institution. I visited gynecological ambulances in South Bohemia personally. By evaluation of questionnaire was found out that dietary supplement with iodine use 63 % pregnant women in researched population. All respondents always use only one type of dietary supplement. Among the most used belong "Chytré miminko", "GS mamavit" and "Femibion 800". 68 % of respondents know the importance of higher iodine intake in time of pregnancy. Question about daily recommended dosage was correctly answered only by 35 % of respondents. As a food sources of iodine the pregnant women know sea fishes, sea products, seaweed and table salt enriched with iodine. But 90 % of respondents are not familiar with milk and milk products as important source of iodine. Pregnant women should be better informed about importance of sufficient supply of iodine and about sources of iodine by gynecological ambulances. Information about mentioned issues should occur in magazines, education materials and internet articles more often. Respondents were notified of issues and important role of iodine in time of pregnancy by questionnaire. It is very probable that women found correct answers on the internet or in publication for expectant mothers after filling in the questionnaire.

Dietary supplements and iodine supplementation for children 11-12 years in the Czech Republic
HALÁSZOVÁ, Monika
Bachelor Thesis called "Dietary supplements and iodine supplementation for children 11-12 years in the Czech Republic" deal with the intake of dietary supplements containing iodine and intake of other significant dietary sources of iodine in relationship to saturation with iodine in the monitored group of 300 children aged 11-12 years . The thesis is divided into theoretical and practical part. Theoretical part deal with established issues in light of current situation and uses the knowledge of specialized literature in these areas: iodine and his dietary sources, influence of deficient or excessive intake of iodine on thyroid gland and its function, and also the solution to iodine deficit in Czech Republic. The thesis also deals with dietary supplements and nutrition of school-aged children. Practical part is focused on quantitative research. This research was done on selected group of children who had low level of ioduria (iodine in urine) according to State health institution. Statistical file included 300 children of both gender in age from 11 to 12 who live in Czech Republic. The reason why children of this age were chosen is because of importance of optimal intake of iodine in period of physical and sexual evolution. The children were divided into two groups. One group had ioduria up to 300ug/l and the second group had ioduria over 300u/l. Data were collected through questionnaire. Because of age of respondents, the questionnaire was filled in presence of at least parent. The questionnaire should have also served to parents as information about iodine importance for their children. The individual evaluation of ioduria and questionnaire was given to parents upon their request. Collected data were evaluated in Microsoft Excel. In practical part, two main goals and two research questions are set. Their task is to determine the rate of usage of dietary supplements with iodine and to find out what significant sources of iodine the children with ioduria over 300u/l take in. The milk and milk products, salt with iodine, salted delicacies, sea products and dietary supplements with iodine were observed as probable main sources of iodine intake. The first goal was to find out the amount of iodine intake from dietary supplements for previously mentioned group of children. The second goal was to find out if the dietary supplements with iodine (or any other combination of food rich on iodine) are used by observed individuals with ioduria over 300u/l. The results of research show if the respondent's level of ioduria is affected by in taking the dietary supplements or food with significantly higher content of iodine. My own research proved relatively frequent (but irregular) intake of dietary supplements with iodine by whole examined population. On the other hand, usage of dietary supplements with iodine is probably not correlated with usage of table salt without iodine or with thyroid gland illness by individual respondent or in his family. The milk and milk products and table salt with iodine proved to be the main source of iodine. According to research, children with excessive ioduria consume sources of iodine as frequent as other children. Deeper insight into results shows that reason for excessive saturation with iodine is combination of intake of dietary supplements as well as other significant food sources of iodine, especially milk and its products. By several respondents, the higher level of ioduria can be caused by higher consummation of sea products or by usage of dietary supplements with iodine in last two days. The need for better awareness about suitable rate of iodine dietary supplements intake as well as medical importance for lowering the amount of (iodine) table salt in food was discovered by research. The optimal supply of iodine by higher percent of observed population could be also achieved by optimizing the content of iodine in milk.

Influence of selected feeding supplements on the occurrence of coccidias in digestive tract of hens
PAZDERKOVÁ, Lenka
Poultry farming represents 30 % of meat production worldwide. The occurrence of animal parasites is an enormous problem of poultry farming. This problem is recorded from factory farming as well as from small farming and causes financial losses. The aim of this study was to gain basic data about the occurrence of coccidia oocysts in the excrements of carrier hens. Carrier hens were fed by dietary supplements which were supposed to have influence on native gut microflora composition. This experiment was conducted on 26 individuals of carrier type hens. It was created the experimental and control group (one group consisted of 13 individuals). The experimental group was prebiotics (Biopolym), probiotics (Lactovita) and homeopathic served 14 days in and between each preparation was 14 days interval. The samples of excrements were tested in a laboratory once a week. The decrease of frequency of coccidian oocysts occurrence in the excrements in the experimental and control group was not proved.

Possibilities of the usage of nonconventional methods and dietary supplements in prevention and in health provision of calves.
PÁNIKOVÁ, Monika
Healthy and strong individuals are fundamental in every cattle breeding. Tthe aim of this study was which of these given supplement had the best influence on calf weight gain in early period after weaning to milk nutrition. This research had continued in cooperation with farm in Hakovy Dvory. Calfs were studied from March 2012 to February 2013. They were weaned into outdoor individual box after birth. There were added supplements into their ration in firs two weeks of life. Calfs were partitioned on the base of addend supplement into three experimental groups and one control group. The first weight control of calfs was after birth and the second weight control was in thirty days of life. From the different of theese values was calculated average weight gain. The best significant effect had tested groups Homeopatics and Prebiotics (Biopolym) with average increment 26,9 kilograms. Next tested group was Probiotics (Lactovita) with average increment 26,1 kilograms. The last goup was Contol, there the calfs didn?t have changed ration and their average increment was 23,5 kilograms. From the results of this study is possible to presume, that calfs had positive reaction on supplements added in first days of life and theese had favourable effect to diarrhoea prevention. Prebiotics, homeopatics and probiotics favourable stimulate calfs digestive system and they have general positive effect on calfs physiological condition.

Sources and methods of saturation of the organism with antioxidants
NOVOTNÁ, Nikola
The aim of the thesis is to characterize sources of antioxidants and inquire the depth of knowledge about antioxidants among students of secondary school. The theoretical part of the thesis describes and divides important antioxidants for human health. The main sources of antioxidants in human diet are there divided, described and compared as well. The practical part of the thesis includes the inquiry which evaluates the theoretical interest in antioxidants and dietary intake of antioxidant supplements among 17-19 years-old secondary school students. The results are analyzed and graphically displayed. Research shows that more than a half of the respondents know the term antioxidants and consume these substances in the diet. However, it is important to increase knowledge of antioxidants already among young people and ensure the intake of these essential substances from a varied diet.

Possibilities of the usage of nonconventional methods and dietary supplements in prevention and in health provision of calves
ZÁBRANSKÝ, Luboš
It is important to take care of calves and their health for good results in beef-raising. The aim of the work was to evaluate the effect of dietary supplements Lactovita and Biopolym on the frequency of diarrhoea occurrence in calves in the first stages of the period after weaning for milk nutrition. The experiment was conducted in farmers' cooperation Staré Hobzí, where Holstein Cattle are bred. Two groups of calves were made {--} control and experimental group. In an experimental group dietary supplements to support active immunity were served according to the guideline. In case of diarrhoea occurrence the calves from experimental group were cured in the same way as the calves from control group. The occurrence of disorders during the period of experiment, method and length of treatment were recorded. Recorded data were summarised and statistically evaluated. The calves were examined from 29th February to 20th December. The results proved positive effect of dietary supplements Lactovita and Biopolym, but these results were statistifically insignificant. It is assumed that in case of studying bigger groups the proof of statistical significance will be more probable.
