Within the elderly population, the use of calcium supplements and the intake of calcium from food are on the rise in order to maintain health. Calcium is absorbed as an ion in vivo, leading to speculation that absorption efficiency is affected by the solubility of the calcium consumed. In our study, the bioavailability of two types of calcium supplements with different solubilities was evaluated. Experimental animals were fed water-soluble or insoluble calcium supplements for 6 weeks. We found that blood alkali phosphatase activity, osteocalcin content, and urine crosslinks values were not different between the groups. Similarly, the degree of apparent calcium absorption between the two calcium supplements was not significantly different. The bone mineral density and bone mineral content of the femur and the tibia increased in the group that consumed insoluble calcium compared with those of the water-soluble calcium supplemented group. However, when considering body weight, the bone mineral density value for all areas, including the spine, was significantly higher in the group that consumed the water-soluble calcium supplement.

Purpose: This study aimed to clarify the characteristics of musculoskeletal problems in elderly Korean women and their actual and current use of dietary supplements by conducting a descriptive survey. Methods: The 1-month study began on April 3, 2012. A total of 150 elderly women from City D responded to the survey questionnaire used in this study. Results: Among the respondents, 55.3% used dietary supplements, although they had not consulted a physician for a definitive diagnosis of their condition but reported a self-perceived musculoskeletal problem instead. In addition, they engaged in healthy behaviors such as exercising and dietary supplement intake, without receiving any medical treatment. Compared with the nonusers, the dietary supplement users self-perceived a relatively more serious musculoskeletal problem (t =4.566, p<.001). Among the most commonly used supplements, multivitamins ranked first, followed by glucosamine and omega-3. Conclusion: Nurses should thoroughly monitor and maintain a positive attitude toward their patients' use of dietary supplements in order to appropriately educate them about the proper use of supplements.

Purpose: Despite the popularity of dietary supplements, little data are available on their use by university students. The purpose of this study was to examine the use of vitamin mineral supplements and to identify factors related to supplement use among university students. Methods: University students (N = 345) in Seoul were surveyed. Survey questions included descriptive demographics, types of vitamin and mineral supplements used, health related lifestyle factors, mini dietary assessment, and knowledge and behaviors related to supplement use. Results: Of university students surveyed, 41% consumed vitamin and mineral supplements. Among the supplement users, multivitamins were the most commonly used dietary supplements (68.6%), followed by vitamin C (31.4%) and calcium (17.1%). In particular, the use of vitamin C and iron supplements was more common in females than males (p < 0.05). For the number of supplements taken daily, 32.1% of supplement users consumed 2 or more supplements; 20% of supplement users had almost no knowledge of the supplements being taken. Based on the results of multivariable logistic regression analysis, supplement use was associated with higher interest in their own health, non-smoker, and supplement use by family (p < 0.05). In addition, supplement use was slightly associated with healthy dietary behavior such as consuming a variety of foods (p = 0.05) and current disease status (p = 0.05). Conclusion: University students with relatively healthy lifestyles appear to take vitamin and mineral supplements, but they had little knowledge of the supplements. Given high prevalence of dietary supplement use among university students, nutrition education regarding supplement use is needed.

Many studies show that the bone loss in postmenopausal women is closely related with status of vitamin K. The purpose of this study is to observe the effects of the vitamin K supplements on the carboxylation of serum osteocalcin in postmenopausal women. Twenty-four healthy postmenopausal women were recruited for the double-blind controlled study. Before and after daily administration of 1.0mg of phylloquinone for one month, the levels of serum vitamin K, osteocalcin, undercarboxylated osteocalcin were measured. Daily intake of vitamin K was also calculated. After the 4-weeks of supplements of 1.0mg/day of vitamin K, there were no significant differences for the levels of serum vitamin K, osteocalcin, and ucOC between the experimental and placebo groups. In this study, it was not found that the supplements of vitamin K to the postmenopausal women had any positive effects on.

Anemia in women during pregnancy and after delivery has been known to affect the mother, the fetus, and the infant's growth and health status. Studies examining, changes in iron and folate status associated with anemia during pregnancy and during pregnancy, and those supplements are stopped after postpartum. However, the effects of those have not been clearly determined in pregnant and lactating Korea women. Therefore, this study was performed to determine the changes in maternal iron and folate status during pregnancy and six months after delivery longitudinally in six pregnant women who consumed supplements from 20 wk to delivery. We concluded that the iron status deteriorated during pregnancy and especially was weak in the third trimester, but had a tendency to recovery after delivery. On the other hand, the folate status deteriorated in the first and second trimester and was good in the third trimester, but had a tendency to decrease after delivery. These results suggested that the iron status was not improved despite consuming total iron supplements of 50 mg/day through diets and supplements during the second half of the pregnancy. On the other hand, the folate status improved at the end of pregnancy by consuming folate supplements of a total of 800 mg/day through diets and supplements. However, folate status was poor in the first half of the pregnancy, and the tendency of folate status to decrease during postpartum was advanced. At the point in which iron and therefore supplementation is essential. However, the effects of supplement intake time and intake dosage need to be verified and the nutritional status changes of postpartum women should be carefully monitored.

The objectives of the present study were to assess the oxidative stability of South Korean n-3 (omega-3 fatty acid) supplements carried out from 2018 to 2019 and evaluate the influence of product characteristics on oxidative safety. A total of 76 n-3 supplements were analysed for oxidation safety by four markers, including acid value (AV), primary oxidation (peroxide value, PV), secondary oxidation (p-anisidine value, pAV) and total oxidation value (TOTOX). Among the supplements tested, 5.3 %, 55.3 %, 28.9 % and 46.1 % exceeded the international voluntary recommended levels for AV, PV, pAV and TOTOX, respectively. Purity (%) of products, remainder of expiration date (suggested shelf life), package in press through package (PTP) and products with additives had statistically significant differences oxidation assessment levels (p < 0.05). In addition, n-3 group found in Algae oil had significantly lower AV levels than the group that did not, and product with Alaska pollack oil, had significantly higher pAV levels than without group (p < 0.05). The high oxidation status of South Korean n-3 products in the present study could not be considered a public health problem right now. However, the levels of oxidation may affect a lot the efficacy and safety of using n-3 supplements. Thus, current oxidation safety limits should be reestablished by regulatory bodies to ensure the safety and efficacy of n-3 supplements, so that the standards could be applied to the products available to consumers.

The purpose of this study is to analyze the cariogenicity of vitamin supplements for children by the Caries Potentiality Index (CPI), pH drop capacity, proliferation rate of Streptococcus mutans. Four vitamin supplements were selected - Noma (NM), Cenovis Kids (CK), Animal Parade (AP), and Character Vitamin (CV). CPI value decreased in the order of AP, CV, CK, and NM. Initial values of all experimental groups showed acidity below pH 7.0. Analysis of the colony forming units of Streptococcus mutans showed that NM and CV resulted a higher proliferation rate (p < 0.05) than CK and AP (p < 0.05). Bacterial activity of the control group was lower than other groups when observed with a confocal laser scanning microscope. Considering the bacterial activity and acidity of vitamin supplements, it is necessary to pay close attention when children taken the vitamin supplements for their oral health.

This study was conducted to investigate the actual conditions of vitamin supplement usage, the importance of their agents for health management, and the distribution of basic data for their correct consumption. For a period of one month 2003, the study was conducted based on questionnaires to the parents of students in both a middle school and a high school, and the personnel of K Company at random. The material used the survey sheets by setting up the previous investigation. The collected data analyzed the frequency and percentage of the following items: General demographic characteristics of consumers; the supplements taking; the reasons for taking them; the kinds of supplements taken; the media used for distributing data on their use; the potential use in the future, etc. According to the survey, the number of people who were taking supplements was higher than the number of people who weren’t taking them. Multi-vitamins were mostly consumed. The rate of supplements consume was high in people of a higher income bracket, had the time to exercise and to enjoy physical recreation. Most of the consumers who were taking the supplements said they did it to maintain their health and to recover from the fatigue. Those who weren’t taking them said they had enough vitamins from eating the appropriate food, and they were also concerned about the effectiveness of taking the supplements. The majority of useful information or advice for purchasing vitamins came from doctors, medical experts, relatives, and various media sources such as TV, newspapers, and magazines.

Thermal stress is a tremendous health predicament encountered by poultry farmers with adverse effects on the performance, product stature, health condition, survival, and overall welfare of poultry birds, and so requires urgent dietary user-friendly strategy to curb. This study was conducted with 200-day old broilers for the purpose of investigating the potential of phytogenics in refining the negative effects of heat stress on broiler chicken. Moringa, Phyllanthus and mistletoe leaves were processed as phytogenic supplements and incorporated into standard ration for broilers as treatments B1 (control), B2, B3 and B4 diet during the peak of thermal discomfort in humid tropics. Growth and carcass indices were monitored in a 49-day trial and blood samples were harvested at the end of the ordeal period to assess haematology, serum biochemical and oxidative stress markers with the use of standard procedures. The results obtained showed that the prevailing environmental condition in the study site indicated that the birds were exposed to heat stress. Birds fed on moringa and mistletoe supplements had higher performance index than birds without supplementation during heat stress condition, while birds fed on mistletoe supplement had the highest survival rate across the treatments. The liveweight, slaughter weight, dressed weight and eviscerated weight of heat stressed birds fed on moringa, phyllanthus and mistletoe supplements were significantly higher than birds on control treatment. Heterophyl/lymphocyte ratio of heat stressed birds without supplement were higher than birds on phytogenic supplements, with least values recorded in phyllanthus and mistletoe fed birds. Birds on phytogenic supplement tend to have lower cholesterol profile, lipid peroxidation and better antioxidant profile than birds on control treatment during heat stress conditions. Mistletoe supplementation in broiler ration enhances the survival rate, as well as promotes growth indices better among the phytogenic supplements. However, phytogenic supplements did ameliorate the negative effects of thermal discomfort on performance, physiological and oxidative stress in heat-stressed broiler chicken.
