An Intervention Study to Investigate the Effect of B-vitamin Supplementation for 2-years on Bone Health (Opti-Age)

December 1, 2023 updated by: Lorraine Brennan, University College Dublin

A Randomised Controlled Trial to Investigate the Effect of Combined B-vitamin Supplementation for 2-years on Bone Mineral Density in Older Irish Adults With Sub-optimal B-vitamin Status

An intervention study to investigate the effect of B-vitamin supplementation for 2-years on bone health. This is a dual centre (UCD and University of Ulster) 2-year randomised, placebo controlled, double blind intervention.

Study Overview

Detailed Description

Osteoporosis is a major public health issue, especially among older adults. The condition is widespread, with an estimated 1 in 2 women and 1 in 5 men over the age of 50 years expected to have an osteoporotic fracture. The associated health care costs are considerable and growing as the population of older adults increases. Furthermore, osteoporotic fractures are associated with loss of independence and risk of further fractures and health problems for the individual. Given these negative impacts, new approaches to help maintain better bone health in older age are urgently needed.

Vitamin D and calcium have well established protective roles, however, other evidence links certain B vitamins with bone health. This study will investigate the effect of B-vitamin supplementation over a two year period at two centres (UCD and University of Ulster)

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Effect of low dose B vitamins on bone mineral density
Time Frame: 2 years
A 2 year Randomized Control Trial (RCT) to investigate the effect of low dose B vitamins on bone mineral density (as measured by dual energy X-ray absorptiometry- DXA) in older Irish adults with sub-optimal B-vitamin status at baseline. A DXA bone scan will be performed pre and post the 2-year intervention to evaluate beneficial effects to bone mineral density
2 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Metabolomics
Time Frame: 2 years
Metabolomics analysis of blood samples collected pre and post the trial to explore the mechanistic effects of B- vitamins on bone and other outcomes
2 years
Neurocognitive function I
Time Frame: 2 years
To determine the neurocognitive function using the Mini Mental State Exam 'MMSE' test (pre- and post-intervention)
2 years
Neurocognitive function II
Time Frame: 2 years
To determine the neurocognitive function using the Repeatable Battery for the Assessment of Neuropsychological Status 'RBANS' test (pre- and post-intervention)
2 years
Neurocognitive function III
Time Frame: 2 years
To determine the neurocognitive function using the Frontal Assessment Battery 'FAB' test (pre- and post-intervention)
2 years
Gut microbiome
Time Frame: 2 years
To collect faecal samples pre and post intervention to explore potential interactions with the gut microbiome
2 years
Blood pressure
Time Frame: 2 years
To measure blood pressure throughout the study and compare baseline to post intervention
2 years
