Most active adults supplement creatine to build muscle size, strength and power. Numerous studies have shown creatine monohydrate to support these goals, and research recently published in the journal Medicine & Science in Sports & Exercisesuggests the ingredient might also support bone mineral density in older adults.

Forty-seven older women supplemented with 0.1 gram of creatine per kg of body weight or a placebo while training with weights 3 days each week. After a year, subjects who used creatine showed a reduced rate of lost bone mineral density and greater bone bending strength compared to placebo.

In addition to improved bone health, subjects who supplemented with creatine increased bench press strength by an average of 64% compared to 34% for subjects who were given a placebo.
