Animal, in vitro and small-scale studies have suggested that creatine supplementation may augment bone mass. This clinical trial aims to investigate the effects of a 2-year creatine supplementation protocol on bone mass in postmenopausal women.

Condition Intervention

Dietary Supplement: Creatine supplementation
Dietary Supplement: dextrose (placebo)

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator)
Primary Purpose: Treatment
Official Title: A 2-year Randomized Controlled Trial: Effects of Creatine Supplementation on Bone Mass and Turnover and Muscle Function in Healthy Postmenopausal Women

Primary Outcome Measures:
  • bone mineral density (BMD) [ Time Frame: 24 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • bone markers [ Time Frame: 24 months ] [ Designated as safety issue: No ]
    will include CTX and P1NP

  • history of falls [ Time Frame: 24 months ] [ Designated as safety issue: No ]

Estimated Enrollment: 200
Study Start Date: November 2011
Estimated Study Completion Date: December 2014
Estimated Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Creatine supplementation Dietary Supplement: Creatine supplementation
The CR group will receive 3g of Cr monohydrate (Creapure®) per day throughout the trial. The amount will be taken as three single doses of 1 g creatine MH during the day (morning, lunch, evening). The dose of creatine will be formulated in a tablet.
Placebo Comparator: Placebo Dietary Supplement: dextrose (placebo)
The placebo group will be given the same dose of dextrose formulated in a tablet to be consumed under the same conditions. The two types of tablets will not be distinguishable from each other having the same appearance, taste and smell.
