Researchers are trying to determine if the vitamin B3 derivative Nicotinamide Riboside (NR) has any effects in bone, skeletal muscle, and metabolic functions and structure in aging.
Successful skeletal muscle regeneration depends on a functional pool of muscle stem cells, termed satellite cells (SC). SC are in a quiescent state throughout adulthood, but undergo multiple cycles of proliferation and self-renewal in response to muscle damage. During aging, there is a loss of SC quiescence, and SC more readily enter an ageing-state impairing their function. Animal studies have revealed a common denominator for increasing SC function and activity, namely...
Can nicotinamide riboside (750 mg/day for 12 weeks) affect the levels of NAD+ in the brain as measured by 31P MRS?
Chronic kidney disease is associated with the loss of skeletal muscle mass and function. This process detrimentally impacts mobility, functional independence, and quality of life. Mounting evidence suggests that chronic kidney disease impairs skeletal muscle functioning by injuring mitochondria, the central energy producing units of cells. Potential treatment options to restore mitochondrial function include aerobic and weight bearing exercise and medications that directly imp...
This study will investigate the effects of 6 week Nicotinamide Riboside supplementation (1000 mg/day) on metabolic health in healthy (pre)obese humans. The primary objective will be hepatic and whole body insulin sensitivity. Secondary objectives, to provide information about the underlying mechanism, will be muscle mitochondrial function, brown fat activity, ectopic lipid accumulation, energy metabolism, cardiovascular risk parameters, body composition and acetylcarnitine leve...
The purpose of this study is to determine the effects of Nicotinamide Riboside (NR) supplementation on metabolism and vascular function following high-fat meal. Differences between young (18-35) and older (60-75) adults will be determined.
Aging is the primary risk factor for cardiovascular diseases (CVD), the number one cause of death in developed societies. Systolic blood pressure (SBP) increase with age and is a key intermediary factor linking aging to increased CVD risk. The primary mechanisms underlying the age-associated increase in SBP is stiffening of the large elastic arteries, which is mediated by increases in oxidative stress, inflammation, and vascular smooth muscle tone. Regular caloric restriction i...
Background: Nicotinamide riboside (NR) is a vitamin B3 dietary supplement. It may help improve muscle function, that may in turn may improve a person s exercise capacity. Researchers want to study how skeletal muscle responds to NR in an individual who has Li-Fraumeni Syndrome and slow muscle energy recovery after exercise. Objective: To study how nicotinamide riboside affects skeletal muscle after exercise. Eligibility: One person at least 18 years old w...
The purpose of this study is to assess the efficacy of supplementation with the Nicotinamide Adenine Dinucleotide (NAD+) precursor compound, Nicotinamide Riboside (NR), for improving physiological function (vascular, motor, and cognitive) in healthy middle-aged and older adults.
NOPARK is a double-blinded randomized controlled trial that studies nicotinamide supplementation in early Parkinson's disease. Parkinson's disease (PD) is a major cause of death and disability and has a worldwide socioeconomic impact. It affects ~2% of the population above the age of 65 years and its prevalence increases dramatically as the population ages. The etiology and molecular pathogenesis underlying PD remain unknown. Recent evidence has implicated an impaired ne...
Nicotinamide riboside (NR) has been available over the counter as a nutraceutical (Niagen®, ChromaDex, Inc.) since the summer of 2013. However, classical pharmacokinetic (PK) data for NR have not been reported in humans. This study will use a recently-developed, whole blood assay for NR to assess the pharmacokinetics of NR at a maximum dose of 1000 mg twice daily, and will collect history, physical examination and laboratory data to determine the safety and tolerability of NR ...
Mitochondrial dysfunction has been implicated in heart failure (HF), and is associated with an imbalance in intracellular ratio of reduced nicotinamide-adenine dinucleotide (NADH) to oxidized nicotinamide-adenine dinucleotide (NAD), or the NADH/NAD ratio. In mouse models of HF, we have found that normalization of the NADH/NAD, through supplementation with NAD+ precursors, is associated with improvement in cardiac function. This Study will randomize participants with systolic HF...
This is a double-blind, randomized, crossover study to investigate the effects of 300 mg/d and 1000 mg/d NR (Niagen) compared to a placebo control on cognitive function, mood and sleep in men and women over 55 years of age.
The primary aim of this study is to investigate the effects of exogenously administered nicotinamide riboside (NR) on brain NAD+/NADH ratio and bioenergetics functions in healthy individuals using phosphorus magnetic resonance spectroscopy (31P MRS) imaging. The secondary aim is to investigate the effects of NR on brain structure and neurotransmitter functions using other neuroimaging methods.
NICE is a randomized clinical trial that will examine the effects of nicotinamide riboside (NR) both with and without resveratrol to test whether, among people with PAD, NR significantly improves walking performance more than placebo and whether NR combined with resveratrol significantly improves walking performance more than placebo. If our findings support our hypotheses, results will be used to design a large, definitive randomized clinical. We will randomize 90 parti...
Mitochondria are important parts of the cell that are responsible for producing energy. The amount of energy they produce depends on how much energy the body needs to function and this energy production can be severely impaired in people with mitochondrial disease. Symptoms of mitochondrial disease vary widely but usually involve the brain, nerves and muscles, as these are tissues that need a lot of energy. Mitochondrial disorders affect 1 in 5000 of the UK population and there...
This study will evaluate the effects of a nutritional supplement called nicotinamide riboside in preventing small fiber nerve degeneration that is experimentally induced by applying capsaicin to skin in otherwise healthy study participants. Furthermore, the effects on nerve regeneration will also be evaluated. The results will be compared to a placebo control drug.
Background: People are living longer and are more likely to survive a heart attack if they have one. Longer life expectancy is good but it also means more people get chronic heart failure over time. This is a condition in which the heart doesn't pump blood as well as it should. Treatment of chronic heart failure has not improved much in a few decades. Researchers want to see if giving a dietary supplement to people with heart failure can help their heart function. The su...
The purpose of this single-arm phase II trial is to determine whether nicotinamide riboside (NIAGEN®) prevents the progression of peripheral sensory neuropathy in patients receiving paclitaxel for treatment of stage IV breast cancer.
Background: The immune system controls how the body responds to infection or injury. Researchers want to see what effect a dietary supplement called nicotinamide riboside (NR) has on the immune system. A study showed that fasting has a good effect on immune cell health in healthy people. And when immune cells were exposed to NR they had a similar positive response as with fasting. Researchers want to see if healthy people have the same effects from NR and fasting, and if...
This clinical trial investigates the effects of nicotinamide riboside (vitamin B3) on the disease course of patients with ataxia telangiectasia. Patients will be treated during four consecutive months with nicotinamide riboside (25mg/kg/day), followed by a washout period of two months. Main study parameters/endpoints: Ataxia, dysarthria, quality of life, laboratory parameters.
While preliminary data show that oral nicotinamide riboside (NR) supplementation increases myocardial levels of oxidized nicotine-adenine dinucleotide (NAD+) levels in mice, there has been no direct evidence that suggests oral NR increases NAD+ levels or improves mitochondrial function in human hearts. This Pilot Study is designed to obtain feasibility data for a planned, larger study testing the hypothesis that oral NR supplementation will increase myocardial NAD+ levels and i...
Vitamin B3 has recently been found to be a potent modifier of energy metabolism, especially the function of mitochondria. Mitochondria power up all cells in our bodies, by generating fuel, ATP, for cellular functions. In previous studies, it has been discovered that mitochondrial biogenesis and oxidative metabolism in adipose tissue is severely impaired in obesity, already at a young adult age. Here the investigators describe a proposal where they use nicotinamide riboside (NR)...
Nicotinamide is an inhibitor of human sirtuins (HDAC III), and is found to re-activate epigenetically silenced tumor suppressors, RUNX3 (runt-related gene 3) and others, in cancer cells. Nicotinamide was found to be effective in several animal cancer models including lung, bladder, liver, etc. The purpose of this study is to determine whether nicotinamide is also effective in the treatment of human lung cancer.
