What shouldn't you do while on creatine? A guide to safe supplementation

4 min read

According to the International Society of Sports Nutrition, creatine is one of the most beneficial sports supplements available. To ensure safety and maximize its effectiveness, it's vital to understand what shouldn't you do while on creatine and to avoid common mistakes that can jeopardize your progress.

Quick Summary

This article explores crucial mistakes to avoid when taking creatine, including excessive alcohol consumption, neglecting proper hydration, and ignoring pre-existing health conditions. It clarifies common myths surrounding caffeine interactions, loading phases, and potential side effects to ensure responsible use.

Key Points

  • Avoid Excessive Alcohol: Heavy drinking is dehydrating and can counteract creatine’s benefits, stressing the liver and kidneys.

  • Prioritize Hydration: Since creatine pulls water into muscles, increasing your daily water intake is essential to support hydration and prevent cramps.

  • Don't Overdose: Sticking to the recommended 3-5g daily dose is both safe and effective; exceeding this amount is wasteful and increases the risk of digestive issues.

  • Consult a Doctor for Medical Conditions: Individuals with pre-existing kidney or liver issues should consult a healthcare provider before using creatine to ensure safety.

  • Don't Cycle Creatine: Cycling is not necessary; continuous supplementation is effective for maintaining muscle saturation in healthy individuals.

  • Mixing with Caffeine is Generally Safe: The myth that caffeine cancels out creatine is largely disproven by modern research, though some may experience minor digestive discomfort.

Don't Consume Excessive Alcohol

Combining creatine with excessive alcohol consumption is a major mistake that can undermine your fitness efforts and health. Alcohol is a known diuretic, meaning it increases urination and can lead to dehydration. Creatine, on the other hand, pulls water into your muscle cells to function properly. When taken together, especially in excess, alcohol's dehydrating effect directly counteracts creatine's hydrating benefits, leading to impaired performance, increased risk of cramping, and hindering muscle recovery. The liver and kidneys are crucial for both processing alcohol and producing and metabolizing creatine. Overworking these organs with excessive alcohol can reduce their efficiency, further diminishing creatine's positive effects.

Don't Forget to Prioritize Hydration

While creatine itself does not cause dehydration in healthy individuals, it does increase your body's water needs. Creatine draws water into the muscle cells, and if your overall fluid intake doesn't increase, you could experience symptoms associated with mild dehydration. Failing to drink enough water can lead to side effects like stomach upset and muscle cramps. To support creatine's cellular volumization effect and maintain optimal hydration, it is recommended to consistently increase your daily water intake. This is especially important during an initial 'loading phase' or during periods of intense exercise.

Don't Overdose or Ignore Recommended Doses

Taking more creatine than the recommended dosage will not produce faster or better results; it is simply wasteful and can cause side effects. Your muscles have a saturation limit for creatine. Once this limit is reached, any excess is converted to creatinine and excreted by the kidneys. High, single doses of creatine (e.g., more than 5 grams at once) are more likely to cause gastrointestinal distress, such as diarrhea and stomach cramps. It is safer and just as effective to stick to the standard maintenance dose of 3-5 grams per day after an optional loading phase.

Don't Ignore Pre-Existing Medical Conditions

For healthy individuals, creatine is generally considered safe for the kidneys and liver. However, those with pre-existing kidney or liver disease should consult a healthcare professional before starting creatine supplementation. Creatine can slightly increase blood creatinine levels, which is a common marker used to diagnose kidney problems. While this is a harmless side effect in healthy people, it can cause confusion in medical tests for those with kidney issues. A doctor can help determine if creatine is appropriate for your specific health situation.

Don't Mix with Incompatible Medications or Harsh Stimulants

Mixing creatine with certain medications can pose risks. Combining it with Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) or diuretics (water pills) should be done with caution and under a doctor's supervision. Diuretics, in particular, can interfere with creatine's hydration properties. Additionally, it is best to avoid powerful central nervous system stimulants (like those in some pre-workout formulas) when taking creatine, as this combination can increase heart rate and blood pressure in some individuals.

Don't Fall for Common Myths

The Caffeine Interaction Myth

One of the most persistent myths is that caffeine cancels out the benefits of creatine. Early, limited studies suggested this, but modern research has largely debunked it. For most people, combining creatine with moderate caffeine intake does not blunt its effects and may even provide a synergistic boost to performance. Some individuals may experience digestive discomfort, so it's wise to assess your personal tolerance. If you have a sensitive stomach, consider separating your intake of creatine and caffeine.

The "Cycling" Myth

Another common misconception is that you must cycle on and off creatine to prevent your body from building a tolerance or to protect your kidneys. Scientific evidence does not support this practice for healthy individuals. Continuous, long-term daily supplementation is considered safe and effective for maintaining saturated muscle stores. A brief 'off-phase' will simply cause your muscle creatine levels to gradually return to baseline.

The Hot Drink and Acidic Liquid Myth

Older rumors suggested that mixing creatine with hot or acidic liquids (like coffee or orange juice) would degrade it into the useless byproduct creatinine. However, extensive research shows creatine is highly stable in liquids, even mildly acidic ones like juice. While it can degrade over a very long period (days or weeks), mixing and consuming it within the same day is perfectly fine.

Comparison of Correct vs. Incorrect Creatine Usage

Action Correct Creatine Usage Incorrect Creatine Usage
Hydration Drink ample water throughout the day, especially during intense training. Neglecting fluid intake, relying on creatine alone for hydration.
Dosage Take a consistent 3-5g daily dose after an optional 5-7 day, 20g loading phase. Taking excessive, single large doses of 10g or more, expecting faster results.
Alcohol Avoid excessive alcohol to prevent dehydration and maximize benefits. Regularly consuming high amounts of alcohol, counteracting hydration and recovery.
Medications Consult a doctor before combining with diuretics, NSAIDs, or strong stimulants. Combining with medication without medical advice, risking adverse interactions.
Cycling Maintain consistent daily supplementation; cycling is unnecessary for most. Pausing creatine intake based on unfounded beliefs about tolerance or safety.
Pre-existing Conditions Seek a doctor's guidance if you have kidney or liver issues. Supplementing without a doctor's supervision despite underlying health conditions.

Conclusion

Creatine is a highly effective and safe supplement for most people when used correctly. By avoiding excessive alcohol, prioritizing hydration, sticking to proper dosage, and ignoring common misconceptions about cycling and interactions with caffeine or acidic liquids, you can reap its performance-enhancing benefits. Always listen to your body and consult a healthcare professional if you have any pre-existing health conditions or concerns.
