I am doing some part time work for a male testosterone replacement company and many of my patients are taking creatine as a supplement to help muscle recovery after strength training workout. Creatine is formed by combining three amino acids. Creatine may enhance athletic performance. It contributes to rapid energy production and may enhance power or speed bursts requiring short periods of anaerobic activity. The reason could be related to the association of creatine supplementation and increased glycogen storage in muscle. Glycogen can quickly release glucose, one of the best sources of instant energy.
Creatine is often taken as a powder but it is also present in “pre-workout” supplements and various energy drinks. Although creatine is present in foods such as meat, fish and milk, consumption of these sources of creatine do not lead to enhanced muscle activity and recovery.
I often see in my clinical practice that patients taking creatine show increase in levels of serum creatinine, which indicates some potential kidney damage. In addition to potential harm to the kidneys, creatine supplementation is linked to:
- Liver damage
- Digestive issues
- Breakdown of skeletal muscle
- Weight gain
My recommendation concerning supplementation with creatine: Check lab testing every 6 months and if there are any signs of kidney, liver or electrolyte abnormalities, supplementation should stop or the amount ingested should be markedly decreased.
Enhancing muscle strength and recovery is a noble goal but be careful of taking supplements that may harm your vital organs.
There are certainly no songs about creatine but here is a Diana Ross song called “Muscles”.
