Can You Mix Creatine with Protein? [Science-Backed Answer]


When following a workout plan, simply eating a balanced diet might not provide all the nutrients your body needs. That's where sports supplements come in handy for gym-goers. Often available as pills or powder, these supplements can be added to milk, water, or fruit juices to make delicious shakes and smoothies. 

Dietary supplements for exercise and athletic performance include products, also known as ergogenic aids, that can (1):  


  • Enhance strength and endurance 

  • Boost exercise effectiveness 

  • Reach performance goals faster 

  • Improve tolerance for intense training 


Protein powder and creatine monohydrate are among the top supplements used by fitness enthusiasts. Many people combine them to build muscle and enhance athletic abilities. Yet, there's uncertainty about when and how to use these supplements and whether mixing these two together is okay.  

In this guide, we'll look at the contrasts between creatine and protein powder, their advantages and drawbacks, and the best ways to use them to reach your fitness targets. Read on to learn more about mixing supplements like creatine and protein.   

Understanding Creatine 

Creatine is a substance made from branched chain amino acids found in your liver, kidneys, and pancreas. ‘Branched chain’ describes the chemical structure of these amino acids. Creatine helps produce energy for muscle movements by making a molecule called adenosine triphosphate (ATP).  

Creatine monohydrate supplements are popular among athletes and gym-goers. They are used to  

  • Build muscle 

  • Improve performance 

  • Enhance energy for high-intensity activities 

  • Speed up recovery 

Besides building strength, creatine might help prevent injuries, aid in rehabilitation, and even benefit your brain. Studies indicate that using creatine for long and short periods is safe for healthy people. Research shows that taking creatine supplements at the recommended doses, usually between 3 to 5 grams per day, or 0.1 grams per kilogram of body weight per day, is generally safe and well-tolerated (2).


There's debate about whether it's best to take creatine before exercise and whether it should be taken with protein. Studies suggest timing isn't critical; what matters is taking it consistently every day (3). Some people choose to have it with their pre-workout drink for extra energy, while others mix it with a protein shake to help muscle tissue grow and recover.

Understanding Protein


Most diets provide enough protein, but athletes and gym-goers may need extra protein for energy and repair of muscle cells. If you neglect your protein intake, your efforts at the gym might go to waste.  

Protein is a vital macronutrient, and it’s essential for:  


  • Muscle growth 

  • Muscle strength 

  • Muscle repair 

  • Overall health 


Using a protein powder supplement can make it fast and easy to get the protein you need. There are many different protein supplements out there, each catering to different diets and health goals.  



  • Whey protein: This is a complete protein derived from milk that comes in different forms, including concentrate, isolate, and hydrolysate, offering varying protein content and digestion rates. 

  • Casein protein: Another milk-derived protein, it's slow-digesting and sustains amino acid release, ideal before bedtime for muscle repair and recovery. 

  • Plant-based proteins: Suitable for vegans, options like rice protein shakes offer hypoallergenic and easy-to-digest alternatives, albeit with lower protein content. 

  • Protein blends: Combining different protein sources like whey, casein, soy, and plant-based proteins, these blends offer comprehensive amino acid profiles and varying digestion rates for different fitness goals and times of the day. 

  • Free-form and hydrolyzed amino acids: These supplements are pre-digested, making them easier for those with digestion issues to absorb. 


When it comes to protein quality, whey is considered the best, which is why many bodybuilders and athletes choose whey supplements.  

Studies show that taking whey protein isolate after working out can help you recover faster and build more muscle. This can make you stronger, prevent muscle loss, and improve muscle function (4).

Aim for about 20–25 grams of protein post-workout. Whey protein powder is a good choice to meet this goal because a typical serving has around 20 grams of protein, which is close to what you need (5). 

The Science of Mixing Creatine with Protein Powder 

Both creatine and protein help grow muscles when used with resistance exercises. A protein shake provides amino acids that help with many body functions and are mostly used to repair and grow muscle. On the other hand, creatine is mainly used for energy, especially during intense activities (6).


Creatine monohydrate boosts your ability to exercise intensely, improving recovery and muscle growth (7). On the flip side, drinking a whey protein shake after exercise gives your body a good protein source, boosting muscle growth by increasing the production of muscle proteins (8). 


Both creatine and amino acids aid in muscle recovery post-exercise. Creatine refuels depleted ATP stores after physical activity, while amino acids provide the building blocks needed to repair muscles.


So, mixing creatine with protein is a wise choice. It won't alter the taste, and your muscles will reap the rewards!  

Benefits of Mixing Creatine with Protein 

Mixing whey and creatine together can be beneficial, as studies have shown positive effects in just 6 weeks. These supplements can increase muscle mass and boost exercise performance compared to a placebo. 


However, it's important to note that effective exercise plays a huge role in achieving optimal results (9). Here are some more benefits of mixing these two together: 

Fat Loss  

Combining a protein shake with creatine supplements can be helpful if you’re aiming to increase muscle mass while losing fat. Research shows both supplements may reduce body fat percentage. Protein helps you feel full and reduces appetite, while creatine helps to burn fat more efficiently when paired with resistance training (10). 

Taste Improvement 

Some people find the taste of creatine unappealing and mix it with a flavored protein shake to mask its taste. This makes it more enjoyable and easier to consume.  

Convenience and Efficiency  

Mixing creatine and protein powder before working out makes it easier to take both supplements together, especially if you have a busy schedule or don’t like the taste of creatine. 


Both substances help with muscle building: whey protein powder aids post-workout recovery, and creatine supplements enhance exercise performance. This leads to higher efficiency and better results.  

Improved Hydration and Performance During Workouts 

You should aim to drink around 3-4 liters of water daily to stay hydrated while taking creatine. Creatine attracts more water when its levels rise in the body. Staying hydrated helps it work better, leading to improved workout performance.   

Considerations and Best Practices  

Taking creatine and whey protein together is safe, but it's important not to overdo either supplement. While there's no strict rule for timing, research suggests that post-workout is the best time to take these supplements (11). 


Timing for creatine isn't critical; consistency matters more. Whey protein is most effective post-workout for muscle recovery. Protein powder isn't typically harmful, but having too many shakes might overwhelm your body's ability to handle the protein. 


Taking excessive creatine can lead to issues like weight gain, muscle cramps, and stomach problems. For this reason, it's crucial to stick to the recommended dose for optimal athletic performance (12).

Considerations and Best Practices

The recommended dosage of creatine supplements is typically around 3-5 grams per day for most individuals, while protein supplements can vary depending on factors like (13):


  • Body weight 

  • Activity level 

  • Fitness goals 


The Recommended Dietary Allowance (RDA) for protein is about 0.8 grams per kilogram of body weight or 0.36 grams per pound. You need this to meet your basic nutritional needs and stay healthy, but it's not necessarily the exact amount you should eat every day.  


To find out how much protein you need each day, multiply your weight in pounds by 0.36, or use an online protein calculator. However, 20–25 grams of protein is recommended post-workout to ensure your muscles recover well. Protein powders typically contain this amount in just one scoop (14).


To avoid over-supplementation, consider the following: 


  • Stick to Recommended Dosages: Follow the recommended dosage guidelines provided on supplement labels to prevent excessive intake. 

  • Consult a Professional: Seek advice from a healthcare provider or nutritionist to determine the appropriate dosage for your individual needs and circumstances. 

  • Monitor Intake: Track your supplement intake from all sources, including fortified foods and beverages, to ensure you're not exceeding safe limits. 


Importance of Choosing High-Quality Supplements  

Not all supplements are the same. Selecting well-known and trustworthy brands of creatine and protein powder guarantees you're using pure and potent products. 


When buying dietary supplements, it's important to pick a trusted brand that uses high-quality ingredients. Choose products that have been tested by third parties to make sure they're pure and effective.  

Myths and Misconceptions  

Myth: Regular creatine supplementation is toxic to the body. 


Fact: Research indicates that regular creatine supplementation is not toxic to the body. Biomarkers like liver enzymes and albumin, as well as organs like the liver and kidneys, are unaffected by creatine. Additionally, symptoms like cramps are less common in users who take creatine supplements at a healthy dosage and stay well-hydrated (15).


Myth: Creatine supplementation leads to kidney damage or renal dysfunction. 


Fact: Despite common concerns, extensive research over 20 years has consistently shown that recommended dosages of creatine supplements do not adversely affect kidney health. Despite this evidence, the misconception that creatine supplementation harms the kidneys persists in the sports nutrition community (16).


Myth: Combining a protein shake with creatine supplements may not be beneficial and could potentially hinder fat loss efforts. 


Fact: Research suggests combining a protein shake with creatine supplements can aid in reducing body fat percentage. Protein promotes satiety and reduces appetite, while creatine (combined with resistance training) boosts fat-burning efficiency and supports muscle gain while losing fat (17). 

Practical Tips for Mixing and Using Creatine and Protein 

Here are some suggestions and practical tips for mixing creatine and protein in shakes and meals: 

  • Shakes: You can blend your protein powder with water, milk, or a dairy-free alternative and mix creatine powder with it. You can also add fruits like bananas or berries for extra flavor and nutrients. 

  • Smoothie Bowls: Make a smoothie bowl using protein powder as the base, then sprinkle creatine powder on top. You can add toppings like granola, nuts, or seeds for added texture and nutrition. 

  • Pair with Meals: Stir protein powder into oatmeal, yogurt, or pancake batter. Sprinkle creatine on top of foods like yogurt or cottage cheese. 

  • Balance with Whole Foods: Prioritize whole, nutrient-dense foods like lean meats, fish, eggs, dairy, fruits, vegetables, and whole grains in your diet alongside supplements. 

  • Stay Hydrated: Drink plenty of water when supplementing with creatine to support absorption and prevent dehydration. 

  • Consult a Professional: For personalized guidance on using supplements safely and effectively, consult with a healthcare provider or registered dietitian.  

The Bottom Line
