Nutritional supplements are commonly accessible products used as an extension to the normal diet and are mostly used by athletes. Among all users of supplements, the utilization among athletes tends to be more noteworthy than the overall public. With such a vast number of athletes utilizing dietary supplements, it is vital to evaluate about side effects of nutritional supplements among gymnasium going athletes. This study was Analytical, conducted on 57 male athletes from Lahore, who were regularly going to gymnasium since past three months and were using nutritional supplements at the time of evaluation. The most frequently used supplements were the mostly consumed nutritional supplements were protein or whey protein powders (61.4%), multivitamins (56.1%), and creatine (38.6%). Most common side effects after utilizing nutritional supplements were Dry Mouth/Dehydration (n=28, 49.1%), Constipation (n=22, 38.6%), Insomnia/Lack of Sleep (n=18, 31.5%) Nausea (n=17, 29.8%) and Heart Palpitations/Abnormal Heartbeats (n=16, 28%). Pearson’s Correlation indicated that the casein protein and soy protein were the major cause of many side effects. It is concluded that athletes were having some side effects after utilizing nutritional supplements and they were utilizing supplements without consulting a proper nutritionist/dietitian.

Because of the interest of patients and physicians, there has been increasing research into the use of botanical agents, nutritional supplements, and diet as a means to manage pain. Pharmacological agents typically are chosen as first-line therapy for pain and symptom management; however, for some patients these agents may not work well long term or have side effects that are not tolerated. Other patients may prefer non-pharmacological therapies. Most clinicians are not trained or may not be comfortable recommending these complementary agents.

Introduction: Using dietary supplements has gained interest amongst people who desire to enhance their body composition. However, there are scant published data regarding the use of nutritional supplements and gym users. This study is to assess the intake of nutritional and dietary supplements among gym members in Sulaymaniyah city, Iraqi Kurdistan. Methods: The results of this study are based on the responses of one hundred gym members (aged over 18 years) to a self-manage questionnaire. Results: Almost half of the sample reported taking nutritional supplements and hormones. Thirty percent of the participants were consuming different protein powders. Most dietary supplement users noticed some side effects. Supplement users should always consult their physicians and been under the supervision of professional trainers and medical practitioners. In this manner, dietary supplements should not cause any side effects such as hypertension, hepatic disturbance, kidney disorders, hepatic, kidney disturbance, and muscle pain. However, some people (gym participants) may experience allergies, upset stomach/abdominal pain, and frequent urination. Conclusion: The usage rate of fitness supplements is very high, and the users are not aware of the potential consequences or dangers of unsupervised practice or unprescribed products. Therefore, there is an immediate need to promote consumers’ awareness of this issue, and the latest scientific data must be provided to users and coaches concerning consuming supplements.

Abstract Background: Essential amino acids (EAAs) promote the process of regulating muscle synthesis. Thus, whey protein that contains higher amounts of EAA can have a considerable effect on modifying muscle synthesis. However, there is insufficient evidence regarding the effect of soy and whey protein supplementation on body composition. Thus, we sought to perform a meta-analysis of published Randomized Clinical Trials that examined the effect of whey protein supplementation and soy protein supplementation on body composition (lean body mass, fat mass, body mass and body fat percentage) in adults. Methods: We searched PubMed, Scopus, and Google Scholar, up to August 2020, for all relevant published articles assessing soy protein supplementation and whey protein supplementation on body composition parameters. We included all Randomized Clinical Trials that investigated the effect of whey protein supplementation and soy protein supplementation on body composition in adults. Pooled means and standard deviations (SD) were calculated using random-effects models. Subgroup analysis was applied to discern possible sources of heterogeneity. Results: After excluding non-relevant articles, 10 studies, with 596 participants, remained in this study. We found a significant increase in lean body mass after whey protein supplementation weighted mean difference (WMD: 0.91; 95% CI: 0.15, 1.67. P= 0.019). Subgroup analysis, for whey protein, indicated that there was a significant increase in lean body mass in individuals concomitant to exercise (WMD: 1.24; 95% CI: 0.47, 2.00; P= 0.001). There was a significant increase in lean body mass in individuals who received 12 or less weeks of whey protein (WMD: 1.91; 95% CI: 1.18, 2.63; P<0.0001). We observed no significant change between whey protein supplementation and body mass, fat mass, and body fat percentage. We found no significant change between soy protein supplementation and lean body mass, body mass, fat mass, and body fat percentage. Subgroup analysis for soy protein indicated there was a significant increase in lean body mass in individuals who supplemented for 12 or less weeks with soy protein (WMD: 1.48; 95% CI: 1.07, 1.89; P< 0.0001). Conclusion: Whey protein supplementation significantly improved body composition via increases in lean body mass, without influencing fat mass, body mass, and body fat percentage.

A statistical experimental design to plastein synthesis which was catalyzed by transglutaminase, using the mixture of soy protein isolate(SPI) hydrolysate and whey protein isolate (WPI) hydrolysate, was investigated. Enzyme/Substrate(E/S:5-25U/g), pH(5-9) and temperature (35-65°C) were selected as major operating variables. To investigate the effects of variables to yield of plastein, the statistical experiment of Box-Behnken design(BBD) and Response Surface methodology(RSM) was employed. Regression analysis showed that the experiment data accorded with the predicted values obtained from quadratic regression equation in BBD with R-Squared of 0.9866 and F-value of 102.51. The optimum results estimated by BBD were as follows: E/S(19.5U/g), pH(6.8), and temperature(50.0°C), gave a maximum plastein yield of 54%. In the present experiment, the preliminary study on plastein functions such as foaming, emulsifying, were showed that plastein had a good biological function.

AbstractThe interest of the supplementation market for the soy protein consumption  to optimize physical and metabolic performance after exercise is increasing. However, evidence suggests that the  soy protein ingestion has lower anabolic properties when compared with whey protein. The purpose of this systematic review was to compare the effects of whey protein and soy protein supplementation on the  muscle functions maintenance after exercise. This review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Articles were searched for in the Pubmed database and included studies comparing the effects of soy protein and whey protein consumption on protein synthesis, lean mass gain and oxidative stress reduction in response to endurance or resistance training. Thirteen trials were included in this review. The results showed that the whey protein consumption is superior to that of soy protein with respect to protein synthesis and lean mass gain, but soy protein showed superior results in reducing oxidative stress. Future research comparing both soy and whey protein are needed to define protein source to be used in nutritional interventions to protein synthesis, lean mass gain and oxidative stress in different populations. Keywords: Soybean Proteins.

No entanto, evidências sugerem que a ingestão da proteína de soja tem propriedades anabólicas mais baixas quando comparada à proteína do soro do leite. O objetivo desta revisão sistemática foi comparar os efeitos da suplementação com whey protein e proteína de soja na manutenção das funções musculares após o exercício. Esta revisão foi realizada usando os Itens de Relatório Preferidos para Revisões Sistemáticas e Meta-Análises (PRISMA). Os artigos foram pesquisados na base de dados Pubmed e incluíram estudos comparando os efeitos da proteína de soja e do consumo de proteínas do soro na síntese protéica, ganho de massa magra e redução do estresse oxidativo em resposta ao treinamento de resistência ou resistência. Treze ensaios foram incluídos nesta revisão. Os resultados mostraram que o consumo de proteína de soro é superior ao da proteína de soja em relação à síntese protéica e ao ganho de massa magra, mas a proteína de soja apresentou resultados superiores na redução do estresse oxidativo. Pesquisas futuras comparando a soja e a proteína do soro do leite são necessárias para definir a fonte protéica a ser usada em intervenções nutricionais para a síntese protéica, ganho de massa magra e estresse oxidativo em diferentes populações. Palavras-chave: Proteínas de Soja.

Usual Diet

The use of dietary supplements (supplementation) is the individual enrichment of the diet with ingredients naturally occurring in food. As a rule, dietary supplements should be used periodically. In nutritional practice, there are many indications for dietary supplementation, but the decision to take dietary supplements should be made by consumers wisely and only in justified situations, when there is a risk that the usual diet does not provide vitamins and minerals in an amount adequate to meet dietary recommendations. However, we should remember about the real dangers of taking too large doses of vitamins and minerals. Many people using dietary supplements, especially several types at the same time, may experience undesirable side effects and deterioration of health, and in addition, people taking medicines may seriously disrupt or weaken the effect of the drug, or even lack the therapeutic effect of the drug. The document presents 10 steps and rules for the use of dietary supplements available on the market, which are addressed to the general population.
