97 Clinical Trials for Various Conditions
The purpose of this pilot study is to evaluate the effects of 4 weeks of daily consumption of encapsulated N-trans-caffeoyl tyramine (NCT) and N-trans-feruloyl tyramine (NFT) at a dose of 120 mg/d on measures of fat oxidation in women with overweight or obesity. The hypothesis is that fat oxidation at rest (measured via indirect calorimetry) and over a 24 h period (measured via d31-palmitic acid stable isotope tracer) will be higher in the group receiving the active study product compared to the control product at the end of the 4-week consumption period.
The purpose of the current study is to examine the effects of a dietary supplement containing plant derived phenolics at two different dose levels in otherwise generally healthy adults with risk factors (high BMI at dyslipidemia and/or pre-diabetes) for body fat composition. The primary hypothesis is that supplementation with plant derived phenolics will decrease body fat composition compared to placebo.
The purpose of the current study is to examine the effects of a dietary supplement containing plant derived phenolics at two different dose levels on parameters of gastrointestinal (GI) health in otherwise generally healthy adults with risk factors (high BMI and waist circumference) for increased GI permeability. The primary hypothesis is that supplementation with plant derived phenolics will improve gut health compared to placebo.
The goal of this study is to use pain-specific urine biomarkers to evaluate how daily nutritional supplementation with biomarker guided formulas effect, quality of life and urinary biomarker scores in chronic pain patients. Assessing the effect of biomarker guided supplementation on pain specific biomarkers through changes in urinary biomarker scores may solidify the necessity for identifying deficiencies to create an individualized treatment plan for pain patients. This study aims to evaluate the effect of biomarker-guided supplementation on the three categories of urinary biomarkers using targeted ingredients specifically designed for oxidative stress, inflammation, and nerve health. This study provides subjects with one of three nutritional supplement formulas based on their specific urinary biomarker test results and assesses changes in their urinary biomarker levels and their quality of life as it relates to their pain over a 3-month period.

This study investigated if elevated BP and aortic stiffness characterized in obese individuals are attenuated following acute grape seed extract supplementation. It is hypothesized that acute dietary supplementation with grape seed extract attenuates aortic stiffness, systolic blood pressure, diastolic blood pressure, mean arterial pressure, and total peripheral resistance and these effects are partially due to reductions in peripheral vasoconstriction
A single-center, double-blind, placebo-controlled, cross-over study pilot study comparing R Drink vs. placebo in 60 heart failure patients. Half of the participants will also have diabetes mellitus. The 60 patients will be distributed among three arms. Total distance walked in six minutes and hospital readmission rates will be examined. Eligible heart failure patients include those with systolic or diastolic heart failure and diabetes mellitus can be Type I or II. All patients will continue on their standard heart failure and diabetes therapies while they participate in the study.

To explore whether dietary supplementation with a version of Anatabloc(R) exerts an effect on blood levels of amyloid beta (Aβ), or impacts global or functional measures of Alzheimer's Disease (AD) in subjects with mild to moderate AD.
Fatty acids or omega-3s are important in the human diet for brain development. Of the three main omega-3s (alpha-linolenic acid: ALA, 18:3n-3; eicosapentaenoic acid: EPA; 20:5n-3; docosahexaenoic acid: DHA, 22:6n-3), DHA and EPA have been studied extensively and have been shown to be important in brain function. Conversely, little is known about the effects of ALA even though the body can make DHA and EPA from it. Because the rate at which ALA makes DHA and EPA is very slow, ALA is not considered an important source of DHA and EPA. However, in the human diet, ALA is more readily available, more easily consumed, and less expensive relative to animal sources of DHA and EPA. So, it is very important that the investigators explore the effects of supplementation with ALA. It is possible that the ALA to DHA and EPA conversion rate can be altered by methylation, an epigenetic form of gene expression and regulation. In the present study, the investigators will examine memory abilities and genetic baselines in 16-month-olds. The investigators will then supplement their food with ALA or control oil for 4 months. At 20 months, the investigators will collect outcome data on memory, fatty acid status, genetic variations, and methylation. The investigators hypothesize that the ALA supplementation will result in an increase in the rate of ALA to DHA and EPA conversion through methylation and genetic variations and subsequently, memory abilities will improve. The data from this study will be used to design a larger R01 grant.
It is believed that probiotic Lactobacillus reuteri will improve the symptoms of breast-fed infants with colic.
An epidemiologic study of patients with asthma has shown that increased intake of soy isoflavones correlates with less severe asthma. In experimental animals, treatment with the soy isoflavone genistein reduces airways inflammation and hyper-responsiveness. In vitro studies performed by us have shows that genistein reduces release of inflammatory compounds by human blood eosinophils. The purpose of this pilot study is to determine whether dietary supplementation with soy isoflavones has effects in patients with asthma. 20 patients with asthma will supplement their diet with a soy isoflavone capsule for 4 weeks. Before and after the supplementation period, we will measure lung function, exhaled nitric oxide (a marker for airway inflammation), collect exhaled breath condensate to measure levels of inflammatory mediators in the airways, and isolate peripheral blood eosinophils to assess the impact of soy isoflavones on their function. We hypothesize that dietary supplementation with soy isoflavones will reduce exhaled nitric oxide level, reduce the inflammatory mediators in the exhaled breath condensate, and reduce the ability of eosinophils to release inflammatory molecules. Identifying if these hypothesized effects of soy isoflavones exist in asthma will provide a justification for further clinical studies.
The aim of this study was to determine whether grape seed extract (GSE) supplementation could reduce the blood pressure (BP) in response to static exercise and post exercise muscular ischemia (PEMI) in normotensive young adults. In 12 healthy subjects (7 male and 5 female, 24.6±3.4 yr), we compared acute effect of both GSE (600 mg) and placebo (PL: 600 mg) on changes from rest in systolic BP (SBP), diastolic BP (DBP), mean arterial pressure (MAP), heart rate (HR), stroke volume (SV), cardiac output (CO), and total peripheral resistance (TPR) during static exercise (SE) and PEMI. Subjects completed 2 min of SE at 30% of maximal voluntary contraction (MVC) followed by 2 min of PEMI.
This study was to examine the additive benefits with combined grape seed extract (GSE) and L-citrulline supplementation on hemodynamic responses to dynamic exercise, 11 young, healthy males were recruited for this study.
The purpose of this investigation is to determine if supplementation with the 4D dietary supplement impacts perceptual-cognitive and visual-motor skills in healthy individuals.
The purpose of this study is to determine whether the consumption of a carbohydrate, carbohydrate plus protein, or placebo sports drink during a 2-hour recovery period effectively moderates performance decrements during a subsequent bout of high-intensity exercise. This information will benefit any endurance-trained masters class athlete who may need to compete or train multiple times a day.
The purpose is to conduct a randomized, single-masked crossover study to determine if acute consumption of a commercially available, highly palatable dark chocolate bar can improve visual performance. Vision testing will include multiple measures of contrast and color perception, reaction time, effects of distraction on visual performance during simulated hands-free phone calls, simulated marksmanship, as well as multiple, objective electro-diagnostic tests including standard and color visual-evoked potentials and various types of electro-retinograms to assess visual pathway function.
Guayusa extract is a caffeinated tea leaf unique blend of antioxidants and caffeine. It is marketed as an ingredient that can help support energy and performance with potential health-related benefits. It has also been indicated as being as safe as any other existing teas (i.e., green tea). However, no studies have previous studied the dose-response effects of guayusa extract for supporting cognitive function, mood, metabolism, nor its effects on resting heart rate, blood pressure, and electrocardiogram characteristics.
The purpose of this study is to evaluates how probiotics and dietary supplementation with an herbal powder can shift the gut microbiome in those with non-cystic acne vulgaris.
This randomized, double blind, placebo controlled study aims to establish the impact of the oral supplement, Immulina TM, on enhancing host resilience to the effects of viral influenza infection in humans.
This small, randomized, double blind, placebo controlled pilot study is aimed at determining the effects of oral Immulina dietary supplementation on specific immune biomarkers in the blood.
This study is being conducted because low lean muscle mass is prevalent among childhood cancer survivors. Lean muscle is the non-fatty muscle tissue that makes up part of the body's lean body mass. Low lean muscle mass is associated with loss of overall body strength, declining mobility and eventually, loss of independence. Among childhood cancer survivors, low lean muscle mass may contribute to reduced physical functioning and a sense of fatigue with exertion, limiting ability to participate in adequate physical activity. Loss of strength and a sense of fatigue with repeated movement make it difficult to participate in daily activities. Although there have not been exercise intervention studies among childhood cancer survivors specifically designed to evaluate the effects of resistance training on muscle mass, studies among individuals with chronic disease, including survivors of adult onset cancers, indicate that resistance exercise improves muscle mass, muscle strength, mobility, vitality and physical activity levels. Resistance training (weight lifting) is a form of physical activity that is designed to improve muscular fitness by exercising a muscle or a muscle group against external resistance. The purpose of the study is to evaluate the effects of resistance training combined with either a protein supplement or a sports drink on changes in lean muscle mass in young adults who were treated for childhood cancer. The sports drink, for this study, is considered a placebo.
