Retrospective Assessment of Changes in Perceived Health Status during Continuous Use of a dietary supplement

引用

Food and Nutrition Sciences 2023年第6期14卷 542-560页

作者： Brett J. West Melissa M. Reid Fernando A. Swartz Deanna M. Latson Research and Development Department PartnerCo Midvale USA

dietary factors play an important role in human health. Specifically, nutritional interventions may have an impact on the hypothalamic-pituitary axis resulting in positive health outcomes. A retrospective health status survey of 386 respondents was conducted to investigate the potential of a dietary supplement, NutrifiiTM Renew, for improving various health outcomes in comparison to a multivitamin/mineral control group. Among those who ingested Renew, 95% reported experiencing at least some improvement in one or more health categories. Compared to the multivitamin/mineral group, the Renew group reported earlier and/or greater improvements in several health status categories including sleep, reproductive health, memory, energy/stamina, skin and hair quality, flexibility, exercise recovery and feeling rested in the morning. A clear majority (84.9%) of Renew consumers reported experiencing noticeable improvement in some aspect of their health within one month. Among those who felt an improvement in sleep, most reported experiencing a change within one week. These improvements were likely due to the synergistic effects of L-arginine, L-citrulline, L-lysine, and botanical extracts on nitric oxide production, growth hormone (GH) release, and sleep quality. The observed improvements in skin elasticity and hair growth may be related to increased GH levels and IGF-1 production. Overall, these findings suggest that Renew may have potential as a dietary intervention for improving various health outcomes beyond those provided by multivitamin/mineral supplementation alone. Further studies are needed to confirm these findings and elucidate the underlying mechanisms of action.

Navigating the Nomenclature of a Purported “dietary supplement”: A Cautionary Tale for Consumers and Practitioners Regarding Tianeptine or “Gas Station Heroin”

引用

Health 2023年第12期15卷 1338-1351页

dietary supplement sales have surpassed $30 billion per year with their use becoming and remaining extremely popular amongst the general public. There are numerous bioactive components, both nutritive and non-nutritive, in dietary supplements with considerable efficacy in promoting health. However, there are many ways disallowed ingredients may enter the supplement pipeline with potentially toxic effects. dietary supplements can be regulated (either pre- or post-market) as a drug, dietary supplement, a nutraceutical, new dietary ingredient (NDI), generally recognized as safe (GRAS) food ingredient, a food additive, or a food. A pharmaceutical drug (medication) is used to treat, cure, prevent, or diagnose a disease and is regulated by the FDA pre-market only and allowed by medical prescription, whereas the other labeling designations are largely regulated post-market. One such molecule with a labeling problem is tianeptine, which has global use as an efficacious, prescribed drug, while at the same time being considered a non-drug and potentially dangerous adulterant often referred to as gas station heroin. In this paper, we critically evaluate the use and labeling of this compound and attempt to clarify the conundrum surrounding its legal or illegal use. Tianeptine is effective and efficacious as an antidepressant in those responding poorly to selective serotonin reuptake inhibitors (SSRIs) and exhibits many medicinal characteristics of tricyclic antidepressants with fewer opioid-like side effects. As a result, sixty-six countries permit use of tianeptine as a prescription drug. At higher doses, tianeptine has recently been shown to exhibit significant potential for abuse and dependency along with toxicity. As such, the US does not recognize tianeptine as an FDA-approved drug or as a dietary supplement, nutraceutical, new dietary ingredient (NDI), GRAS ingredient, or a food. Instead, tianeptine is a synthetic adulterant of a dietary supplement and considered technica

Food and Nutrition Sciences 2022年第5期13卷 493-503页

作者： Fatou Corka Kane Djimadoum Kimassoum Simo Fredy Brice Moundipa F. Paul Wilfred F. Mbacham Department of Biochemistry Faculty of Science University of Yaoundé I Yaoundé Cameroon Mushroom Biotechnology Laboratory Department of Plant Biology and Physiology Faculty of Sciences Cheikh Anta Diop University of Dakar Dakar Senegal Laboratory for Food and Drug Safety and Publci Health Biotechnologies University of Yaoundé I Yaoundé Cameroon Centre for Health Inplementation and Translattional Research The Fobang Institutes Yaoundé Cameroon

The antioxidant property of Moringa oleifera leaves and Pleurotus ostreatus on swimming performance and related biochemical parameters were investigated in thirty adult male and female wistar rats. Purpose: The aim of the present study was to evaluate the antioxidant property of M. oleifera and P. ostreatus mixture in specific proportions in wistar rats. Material and Methods: The mushroom species and M. oleifera leaves were cultivated at the biotechnology laboratory of the University Cheikh Anta Diop de Dakar, Senegal. Oxidative stress in rats was induced by swimming. The dietary supplement was composed of a mixture of powders of Moringa oleifera and Pleurotus ostreatus in 2:1 ratio. Three groups received different doses of dietary supplements 500 mg/kg, 1000 mg/kg, and 1500 mg/kg, with one group being the stressed and the other the control group. Parameters in serum such as serum glutamyl oxaloacetate transaminase, serum glutamyl pyruvate transaminase, albumin, Testosterone, creatinine, and, oxidative stress parameters (catalase, reduced glutathione, and malondialdehyde) were measured. Results: Results showed that the dietary supplement has an effect on oxidative stress because it increases the activity of catalase and the level of cellular glutathione in rats. The 500 mg/kg dose would be the most appropriate dose for stressful conditions. The 1000 mg/kg dose would be the most appropriate dose for liver damage. Conclusion: This study shows that the antioxidant properties of M. oleifera leaves and Pleurotus ostreatus are demonstrated by their ability to improve body energy stores and tissue antioxidant capacity. The dietary supplement of M. oleifera leaves and P. ostreatus powders mixture could be good in stressful conditions.

Pigmentation Restored in Mutant Laboratory Strain of the Lady Beetle <i>Coleomegilla maculata</i>through dietary supplementation

引用

Advances in Entomology 2016年第3期4卷 133-140页

作者： Margaret Louise Allen US Department of Agriculture Agricultural Research Service Biological Control of Pests Research Unit Stoneville Mississippi USA

A laboratory colony of Coleomegilla maculata (DeGeer), ye, selected for a pigmentation deficiency, was restored to near wild type cuticle coloration by adding crushed heads and wings of the red colored parental strain to the diet. While the wings and other colored portions of the cuticle re-gained the red color, the eyes of the pigmentation deficient insects were not changed from the pale mutant form. Plant derived carotenes lycopene and beta-carotene did not restore the mutant beetles to a visibly distinguishable red color. An additional pigmentation deficient mutant strain, gold, partially recovered red cuticle color when provided with diet containing pigmented insect particles. This work represents the first rescue of a color phenotype in a lady beetle.

The purpose of this investigation was to evaluate the effect of a dietary supplement （Mirigen TM）, a fungal cell wall derivative product, as a new generation alternative to antibiotics, on the growth and the innate and adaptive immune functions in broilers from birth to 45 d of age. Newborn chicken were randomly assigned to one of three groups： G 1 （n=150） controls no supplement fed; G2 （n=150） is fed with dietary supplement at a designed regular dose （0.5 %, weight of additive to food）; G3 （n= 150） is fed with dietary supplement at double doses （1%）. All three groups were housed in the same conditions. Body weight and blood were taken on day 1, 14, 28 and 45. Medications used and costs/treatment were recorded for each group. The whole blood was used to purify heterophils for reactive oxygen species （ROS） generation and E coli killing abilities examination assays, and the serum samples were preserved in freezer for enzyme linked immunosorbent assays （ELISAs） to determine concentration of macrophage inflammatory protein-1β （MIP-1β）, CD4/CD8, interferon-y （IFN-y）, and titers of antibody against Newcastle disease virus （NDV）. Group differences were analyzed using analysis of variance （ANOVA） algorithm （S-Plus）. There was no significant birth weight difference in three groups. After 45 d growth, the dietary supplement treated groups had significantly higher body weight gain （BWG） with lower mortality rate if compared to the untreated control group （P〈0.05）. Their BWG and mortality rate were 2.23 kg and 10 % in GI （control group）, 2.89 kg and 2 % in G2 （experimental group, 0.5 % dose）, and 2.77 kg and 1% in G3 （experimental group, 1% dose）, respectively. Heterophil ROS generation in treated groups were markedly improved through the addition of dietary supplement in both regular and double doses to the diet （P〈 0.05）. The ability of heterophil to kill E coli was also significantly improved in dietary supplement treated groups （P〈0.01）. Comparing to control group, there w
