Five Foods High in Creatine

author avatar Dr. Eric Berg 09/11/2023

Creatine is an amino acid complex with several health benefits. It promotes neuronal function and boosts physical performance by recycling adenosine triphosphate (ATP)—the primary energy source of skeletal muscles.

Discover five foods high in creatine you should eat regularly to promote muscle gain and support brain health.

What is creatine?

Creatine is an organic compound comprising the amino acids arginine, glycine, and methionine. It’s synthesized in muscles and stored as creatine phosphate.

Creatine phosphate plays an essential role in muscle contractions and serves as a quick energy source, especially during short bursts of high-intensity activities such as sprinting and weightlifting. 

Because of its role in skeletal muscle function, nutritional supplements containing creatine are becoming increasingly popular among weight-lifters and endurance athletes

Watch the video below to learn about creatine's benefits for muscle function and recovery. 

Five foods high in creatine

Creatine is naturally produced and stored in muscle tissue and can be found in various animal products, including most cuts of red meat, poultry, and fish.

Here are five natural food sources of creatine.

1. Red Meat

Red meats such as beef, veal, lamb, venison, and rabbit are excellent natural creatine sources. 

According to research published in Nutritional Supplements for Endurance Athletes, a six-ounce (170-gram) serving of beef contains around 750 milligrams of creatine. 

2. Fish and seafood 

Fish, especially herring, salmon, and tuna, are rich in natural creatine. 

A six-ounce serving of herring can provide as much as 1.7 grams of creatine, making it one of the best food sources of this performance-boosting compound.   

3. Poultry

While chicken, turkey, fowl, and duck contain less creatine than beef and fish, regularly eating poultry can significantly contribute towards overall creatine intake. 

A six-ounce serving of chicken breast contains around 450 milligrams of creatine.

4. Pork

Pork is another excellent source of creatine, providing 650 milligrams per six-ounce serving of pork tenderloin.

5. Dairy Products

Dairy products, including milk, yogurt, and cheese, also contain natural creatine, although in significantly smaller amounts than meat, poultry, and fish.

However, parmesan cheese is an exceptionally rich source of creatine, containing around 2.9 grams per 3.5-ounce (100-gram) serving.

Sources of creatine

Vegan sources of creatine

Creatine is mainly found in the muscle meat of animal products, and many plant-based foods are low in methionine, glycine, and arginine, the building blocks for creatine.

This leaves vegans and vegetarians at risk of low creatine stores.

A study published in Medicine and Science in Sports and Exercise found that vegans tend to have significantly lower creatine muscle levels than omnivores or those following a carnivore diet.  

However, consuming plenty of vegan plant-based protein sources can help you obtain a wide range of amino acids, including those necessary to generate creatine. 

Here are ten vegan sources of amino acids needed for creatine synthesis:

  1. Pumpkin seeds

  2. Sesame seeds

  3. Walnuts

  4. Almonds

  5. Watercress

  6. Spinach

  7. Asparagus

  8. Spirulina 

  9. Chickpeas

  10. Legumes 


Because plant-based foods lack creatine, vegan athletes have been found to benefit from supplementing creatine to achieve optimal creatine muscle reserves. 

Most creatine supplements are synthetic and not derived from animal products, which makes them suitable choices for vegans and vegetarians.

Benefits of creatine

Creatine has gained increasing popularity due to its performance-enhancing properties and may be beneficial in the management of certain medical conditions. 

Here are four creatine benefits.

1. Enhanced muscle strength and power

Creatine can increase the body's capacity to perform short-term, high-intensity activities by recycling ATP, an electrically charged molecule needed for muscle contractions.

ATP recycling helps maintain energy production within muscle cells, which supports high-intensity exercises and may prolong endurance.

2. Promotes muscle gain 

Creatine has been found to draw water into muscle cells, which contributes to muscle growth and improved muscle volume.

In addition, adequate creatine levels, especially when combined with resistance training, stimulate protein synthesis needed for building and maintaining muscle mass.

3. Faster exercise recovery 

Creatine is a recovery nutrient that has been found to reduce muscle damage and inflammation after intense workouts.

Creatine also helps replenish ATP in muscle cells post-workout, which promotes muscle repair and stimulates muscle fiber formation and muscle mass gain.

4. Neuroprotective effects 

Research published in Sports Medicine found that creatine may be beneficial in the treatment of neurological disorders, such as Parkinson's disease and amyotrophic lateral sclerosis (ALS).

“The brain has an incredibly high rate of metabolic processes that constantly require ATP,” explains Dr. Berg. “Creatine’s ability to increase ATP concentrations in brain tissue may explain its potential benefits for cognitive function and neuronal health.”

There is also evidence that creatine may promote balanced neurotransmitter levels needed for synaptic function and communication between brain cells.

How much creatine do you need?

A study published in The Journal of the International Society of Sports Nutrition states, “Creatine stores can generally be maintained by ingesting 3 to 5 grams daily.”

The body produces 1 to 2 grams of creatine per day, and most people obtain around 1 gram from food sources, which may be enough to maintain adequate muscle stores.

However, short-term creatine loading doses of up to 10 grams daily may be necessary to replenish low creatine stores and achieve optimal muscle concentrations.

 Creatinine blood marker

Creatine vs. creatinine 

You may have heard of creatine as a dietary supplement and noticed creatinine listed as a marker on metabolic blood panels—so what’s the difference?  

Creatine is a functional amino acid compound that helps replenish energy in muscle cells. Creatinine, on the other hand, is a metabolic waste product of creatine breakdown.


Creatine phosphate replenishes energy by donating a phosphate group to adenosine diphosphate (ADP), which generates ATP and creatinine.

The kidneys filter creatinine from the bloodstream and excrete it via the urine, making it a helpful blood marker that’s used to evaluate kidney function and diagnose stages of kidney failure.

What causes high creatinine?

Creatinine is excreted through the kidneys, and high creatinine levels can indicate kidney damage or an accelerated breakdown of muscle tissue due to intense and prolonged exercise, starvation, or metabolic disorders. 

Abnormal creatinine concentrations can also indicate liver disease, gallbladder disease, inflammation, or muscle injury.

In addition, it’s not uncommon to develop high creatinine on the ketogenic diet

This is generally caused by eating too much protein on keto and can easily be managed by staying within four to six ounces (110 to 170 grams) of protein per meal. 

Watch the video below to learn more about common causes of high creatinine on keto. 

Is creatine supplementation safe?

Increasingly more people are asking what creatine is and wonder if taking a creatine supplement may benefit their athletic performance and muscle strength.

But is creatine supplementation safe? 

Yes, for most healthy adults, taking a creatine supplement in recommended doses is safe. 

While creatine is generally well tolerated, excessive intake can cause gastrointestinal issues, dehydration, and electrolyte imbalances, and it’s essential to follow the recommended dosages of the creatine product you plan to use. 

When choosing a creatine supplement, carefully check the label and opt for a product without unnecessary additives or fillers. 

Creatine is available in different elemental forms, including:

  • Creatine ethyl ester and 

  • Micronized creatine 

  • Creatine monohydrate 

  • Creatine citrate

  • Buffered creatine

Because creatine creates waste products that are processed by the kidneys, people with kidney issues should consult a healthcare professional before taking creatine supplements.

The safety of creatine supplementation during pregnancy and breastfeeding hasn’t been adequately studied, and there is limited information about its potential effects on the mother and the developing child.

High-intensity workout

Key takeaways

Creatine is an amino acid compound that increases available energy in muscle cells, which can enhance physical performance and endurance. 

Consuming plenty of foods high in creatine, such as beef, pork, fish, and poultry, or taking a creatine supplement can shorten recovery time after workouts, aid muscle repair, boost muscle growth, and benefit brain function and cognitive health. 

Creatine is only found in animal products, leaving vegans and vegetarians at risk of inadequate creatine muscle stores linked to lower exercise tolerance and difficulties building muscle strength.

4. What food is highest in creatine?

Herring contains 1.7 grams of creatine per six-ounce (170-gram) serving, making it one of the best food sources of creatine.  

Other exceptionally high sources of creatine include beef, pork tenderloin, and parmesan cheese. 

5. What vegan foods are naturally high in creatine?

Creatine is mostly found in the muscle meat of animal products. 

However, vegans can obtain creatine naturally by consuming foods that are rich sources of amino acids needed to synthesize creatine, such as pumpkin and sesame seeds, walnuts, almonds, watercress, spinach, and spirulina. 

6. Do any vegetables have creatine?

No, vegetables don’t contain creatine.  

7. Do eggs have creatine?

While eggs are a rich source of protein, they contain very small amounts of creatine.

8. Are eggs high in creatine?

No, eggs don’t contain significant amounts of creatine. On average, a large egg contains around 4 milligrams of creatine, which is minimal compared to red meat and fish.

9. What is the fastest way to increase creatine?

A diet rich in animal products such as beef and fish can increase muscle creatine stores for most people. 

However, endurance athletes and individuals with large muscles often have higher creatine requirements and may benefit from taking supplements to achieve optimal creatine levels. 

10. What supplements are high in creatine?

Dietary supplements high in creatine are typically in powder form and either contain pure creatine or are blended with amino acids. Creatine is available in several elemental forms, including creatine ethyl ester, micronized creatine, creatine monohydrate, and buffered creatine.
