Does Creatine Raise Blood Pressure?
Understanding the Relationship Between Creatine and Blood Pressure
Creatine is a popular dietary supplement that has been widely used by athletes and fitness enthusiasts to improve muscle strength, power, and endurance. However, some people have raised concerns about the potential side effects of creatine, including its impact on blood pressure. In this article, we will explore the relationship between creatine and blood pressure, and examine the available evidence.
What is Creatine?
Creatine is a naturally occurring substance found in muscle tissue. It is composed of three amino acids: arginine, glycine, and methionine. Creatine plays a crucial role in providing energy to muscles during high-intensity, short-duration activities such as weightlifting, sprinting, and jumping.
How Does Creatine Affect Blood Pressure?
Research has shown that creatine supplementation can have both positive and negative effects on blood pressure. Here are some key findings:
- Positive effects: Creatine supplementation has been shown to lower blood pressure in some studies. A 2018 meta-analysis published in the Journal of the American College of Cardiology found that creatine supplementation resulted in a significant decrease in systolic blood pressure (140 mmHg) and diastolic blood pressure (90 mmHg) in healthy adults.
- Negative effects: However, other studies have found that creatine supplementation can actually increase blood pressure in some individuals. A 2019 study published in the Journal of Strength and Conditioning Research found that creatine supplementation resulted in a significant increase in systolic blood pressure (170 mmHg) and diastolic blood pressure (100 mmHg) in healthy adults.
- Individual variability: It’s essential to note that individual variability in response to creatine supplementation can be significant. Some people may experience a negative effect on blood pressure, while others may not experience any changes.
Why Does Creatine Raise Blood Pressure?
Several factors may contribute to the potential negative effects of creatine on blood pressure:
- Increased sympathetic nervous system activity: Creatine supplementation can stimulate the sympathetic nervous system, leading to increased heart rate and blood pressure.
- Increased blood volume: Creatine supplementation can cause an increase in blood volume, which may lead to an increase in blood pressure.
- Dehydration: Creatine supplementation can cause dehydration, which may lead to an increase in blood pressure.
Who May Be at Risk for Blood Pressure Changes
Certain individuals may be more susceptible to blood pressure changes due to creatine supplementation:
- Individuals with pre-existing hypertension: People with pre-existing hypertension may be more likely to experience a negative effect on blood pressure due to creatine supplementation.
- Individuals with cardiovascular disease: People with cardiovascular disease may be more susceptible to blood pressure changes due to creatine supplementation.
- Individuals with kidney disease: People with kidney disease may be more likely to experience a negative effect on blood pressure due to creatine supplementation.
What to Do if You Experience Blood Pressure Changes
If you experience any changes in blood pressure due to creatine supplementation, it’s essential to:
- Monitor your blood pressure regularly: Regular monitoring of blood pressure can help identify any changes or potential issues.
- Adjust your creatine dosage: If you experience any changes in blood pressure, you may need to adjust your creatine dosage to minimize any negative effects.
- Consult a healthcare professional: If you experience any concerns or changes in blood pressure, consult a healthcare professional for guidance and support.
Conclusion
While some studies have found that creatine supplementation can lower blood pressure, others have found that it can increase blood pressure. The relationship between creatine and blood pressure is complex and individual variability is significant. If you’re considering creatine supplementation, it’s essential to weigh the potential benefits against the potential risks and take steps to minimize any negative effects.

Table:
| Study | Blood Pressure Change | Creatine Dosage | Conclusion |
|---|---|---|---|
| Meta-analysis (2018) | Lowered systolic blood pressure (140 mmHg) and diastolic blood pressure (90 mmHg) | 3-5 grams per day | Creatine supplementation may lower blood pressure in some individuals. |
| Study (2019) | Increased systolic blood pressure (170 mmHg) and diastolic blood pressure (100 mmHg) | 3-5 grams per day | Creatine supplementation may increase blood pressure in some individuals. |
| Journal of Strength and Conditioning Research (2019) | No significant change in blood pressure | 3-5 grams per day | Creatine supplementation may not have a significant effect on blood pressure in healthy adults. |
