Comprehensive Guide to Creatine: Benefits, Side Effects, and Dosing
This session explores the benefits and potential side effects of creatine supplementation, commonly used to enhance athletic performance. It also covers dosing guidelines and provides references for further reading on creatine's safety and efficacy.
Creatine
Creatine is a popular dietary supplement commonly used to enhance athletic performance, particularly in high-intensity, short-duration activities such as weightlifting and sprinting. Here are the benefits and potential side effects of creatine supplementation:
Benefits
-
Enhanced Athletic Performance:
Creatine improves strength and power output during resistance exercises1. This is due to its role in increasing the availability of phosphocreatine, which is essential for adenosine triphosphate (ATP) production2. -
Increased Muscle Mass:
When combined with resistance training, creatine supplementation can increase lean muscle mass3. -
Improved High-Intensity Exercise Capacity:
Creatine is particularly effective in improving performance in activities that involve repeated short bouts of high-intensity exercise. This includes sports like football, hockey, and sprinting4. -
Potential Neuroprotective Effects:
Some studies indicate that creatine may have protective effects in muscle, heart, and neurological conditions5.
Side Effects
-
Water Retention and Weight Gain:
One of the most common side effects is weight gain due to increased water retention6. This can be a concern for athletes in weight-controlled sports. -
Gastrointestinal Distress:
Some individuals report gastrointestinal issues such as diarrhea, stomach upset, and bloating, especially when taking high doses of creatine7. -
Renal and Liver Effects:
While well-controlled studies generally show no significant adverse effects on liver and kidney function in healthy individuals8, there have been occasional reports of creatine causing renal complications, particularly at high doses9. -
Muscle Cramping:
There are anecdotal reports of muscle cramping associated with creatine use, although scientific evidence supporting this claim is limited10.
Dosing
- Loading Phase: 0.3 g/kg/day for 5 to 7 days.
- Maintenance Phase: 0.03 g/kg/day for several weeks to months11.
