Creatine and Aging: Does Supplementation Help?

Aging is a natural process that brings with it a gradual loss of muscle mass, strength, and functional abilities. This phenomenon, known as sarcopenia , is associated not only with weakening of the musculoskeletal system, but often also with bone loss and cognitive decline. Science now shows that creatine supplementation - especially in combination with strength training - can play an important role in supporting healthy aging in older people.

What is creatine and why is it important?

Creatine is a substance that the body can produce itself from the amino acids arginine, glycine and methionine, and which we also obtain from food (e.g. red meat, fish).

Up to 95% of all creatine in the body is stored in the muscles, the rest is found in the bones and brain. In cells, it is stored in the form of phosphocreatine , which helps to quickly regenerate ATP - the basic source of energy for muscle work.

In older people, creatine supplements can support muscle and brain function precisely due to the greater availability of this energy.

Creatine and muscle mass in the elderly

• Long-term studies (up to 2 years) show that creatine supplementation along with strength training leads to an increase in muscle mass of approximately 1.4 kg in older adults.

• A study using advanced imaging methods (pQCT) confirmed that creatine, together with strength training, also increases muscle density in the lower extremities compared to placebo.

• Positive effects also include improved upper and lower body strength , better functional abilities (e.g., common daily movements), and frequent decreases in body fat.

The conclusion is clear: creatine combined with training can significantly slow down the process of sarcopenia.

Creatine and bone health

Creatine also enters bone cells, where it is involved in energy metabolism. Research suggests that it may support the activity of osteoblasts (bone-forming cells) and contribute to the differentiation of cells associated with bone formation.

However, the evidence is not yet consistent. Most studies have not shown a significant increase in bone mineral density in older people.

Creatine may have a positive effect on bone health, but science does not yet have a clear answer.

Creatine and the brain

Creatine is not just important for muscles – it also plays a role in the brain, where it can function as an energy buffer similar to that in muscle cells.

Some studies show that creatine supplementation can improve memory and cognitive function in older people. Although this area of ​​research is not as extensive, it is a very promising direction.

Summary

• The combination of creatine and strength training in older adults leads to an increase in muscle mass, strength, and functional abilities.

• The effect on bone health is less clear, but potentially positive.

• Creatine also has promising effects on the brain and cognitive function.

• Supplementation alone without exercise has limited effects - the greatest benefits always come in combination with strength training.

Creatine is not just a supplement for athletes. Research shows that it can also be an important tool in preventing age-related muscle and strength loss and helping to maintain quality of life in old age.
