NCT01472393

Brief Summary

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.

Study Arms (2)

Creatine supplementation

EXPERIMENTAL
Dietary Supplement: Creatine supplementation

Placebo

PLACEBO COMPARATOR
Dietary Supplement: dextrose (placebo)

Interventions

Creatine supplementationDIETARY_SUPPLEMENT

The CR group will receive either 1g or 3g of Cr monohydrate (Creapure®) per day throughout the trial. The dose of creatine will be formulated in a tablet.

Creatine supplementation
dextrose (placebo)DIETARY_SUPPLEMENT

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.
