About this study
Official title: A Randomized, Double-blinded, Placebo-controlled Study to Evaluate the Effects of Vitamin B3 Derivative Nicotinamide Riboside (NR) in Bone, Skeletal Muscle and Metabolic Functions in Aging
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.
Read the detailed description
Primary Objective: To assess the effect of "NAD boosting" through NR intake in skeletal muscle and bone metabolism function, and biochemical evidence of improvement of DNA damage repair in healthy elderly female patients with and without exercise.
Secondary Objective: To assess the effect of NR in metabolic functions of glucose and lipid profile as well as to determine the safety of long term administration of NR in healthy elderly female patients with and without exercise.
- Conditions
- Healthy Elderly Volunteers
- Being tested
- Nicotinamide Riboside, Placebo

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Nicotinamide RibosideDietary supplement
It will be administered a total of 1000 mg/day of NR in a regimen of 500mg every 12 hours by mouth for 4.5 months. After 4.5 months, an advanced individual training (AIT) will be implemented in addition to administration of 1000mg/day (500mg every 12 hours) for 6 weeks more, completing total of 6 months.
PlaceboDietary supplement
It will be administered a correspondent placebo with the same shape and color as the active pill 12 hours by mouth for 4.5 months. After 4.5 months, an advanced individual training (AIT) will be implemented in addition to administration of correspondent placebo every 12 hours for 6 weeks more, completing total of 6 months.
| Study group | Role | What they receive |
|---|---|---|
| Nicotinamide Riboside | Active comparator | NR is a single chemical moiety containing nicotinamide and ribose. The investigational product is a synthetic NR that is nature-identical to naturally-occurring NR, does not induce flushing or pruritus and has no effect on lipid levels. Receives: Dietary Supplement: Nicotinamide Riboside |
| Placebo | Placebo comparator | Correspondent placebo, a pill not containing the active component. Receives: Dietary Supplement: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Maximal oxygen uptake (VO2 max) test
Maximal oxygen uptake (VO2 max) test measures the maximum rate of oxygen consumption during incremental exercise (exercise of increasing intensity) and reflects the cardiorespiratory fitness of an individual and is an important determinant of their endurance capacity during prolonged exercise.
Measured: 6 months
Skeletal muscle function
The 6-minute walk test (6MWT) quantifies the distance a person can walk in six minutes and will be used to document the mobility/functional status of a patient. Originally developed to evaluate the physical capacity of patients with cardiopulmonary diseases, the test has been used to assess treatment effects, physical function status, and to predict morbidity and mortality in several patient populations including frail older adults.
Measured: 6 months
Short Physical Performance Battery (SPPB)
The SPPB captures domains of strength, endurance, and balance and is highly predictive of subsequent disability.
Measured: 6 months
Respiration rate on muscle biopsy samples
The samples will be analyzed for respiration rate in isolated mitochondria and permeabilized fibers
Measured: 6 months
PCR on muscle biopsy samples
RT-PCR for gene expression
Measured: 6 months
Immunoblot on muscle biopsy samples
Immunoblot in skeletal lysates for protein expression
Measured: 6 months
Bone metabolism
Serum Carboxy-terminal Telopeptide (CTX), tartrate-resistant acid phosphatase isoform type 5b (TRAP5b), Amino-terminal Pro-peptide (P1NP), and osteocalcin will all be measured to monitor bone turnover markers.
Measured: 6 months
Secondary outcomes (5)
Glucose profile
Serum glucose measure
Measured: 6 months
Insulin
Serum insulin measure
Measured: 6 months
Lipid profile
Blood cholesterol measure
Measured: 6 months
Hemoglobin A1C
Hb A1C measure in blood sample
Measured: 6 months
Oral glucose tolerance test
An 18-gauge cannula will be inserted in a retrograde fashion into a dorsal hand vein of the non-dominant arm. The hand will be placed in a heated box (55°C) to enable sampling of arterialized venous blood. Blood will be drawn at 0 (baseline), 10, 20, 30, 60, 90, and 120 minutes for the measurement of glucose, insulin, and C-peptide concentrations. After the baseline blood draw, subjects will ingest 75 g of glucose over a period of 5 minutes.
Measured: 6 months

For those subjects interested and qualified it will be offered participation in this trial. Once consent has been obtained baseline values will be established and subjects will begin treatment and followed for 4.5 months. After 4.5 months, a structured exercise regimen will be implemented in addition to the NR/placebo treatment and the patients will be followed for 6 weeks more, completing 6 months.
