Which Food Has The Highest Glutamine? 10 Foods High In Glutamine

Want to get more glutamine, which is good for your muscles, tummy, and staying healthy? While no single food has the absolute most, some common foods have a lot! This list will show you the top ten easy-to-find foods high in glutamine, helping you get more of it in your everyday meals:

1. Red Cabbage

This red veggie offers antioxidants, especially anthocyanins, which help fight inflammation while also offering a good dose of glutamine that supports gut health.
 

Regularly adding shredded red cabbage to your meals can help repair your intestinal lining and improve digestion, especially for people with leaky gut or IBS.
 

It’s also rich in vitamins C and K, boosting your immune system and helping wounds heal faster. These foods high in vitamin K, also keeping you full longer with their fibre, making it a great option for weight management.
 

Whether fermented into sauerkraut, tossed into stir-fries, or used in fresh slaws, this vegetable has a lot more to offer than most of us think.

2. Beets

They are a natural source of glutamine that helps your body heal and recover. When you eat beets, especially when steamed or roasted, you’re giving your body fuel to support muscle repair, boost stamina, and clean the digestive tract.
 

The natural nitrates in beets also enhance blood flow, which means more oxygen gets delivered to your muscles and brain. This combo makes beetroot benefits great for athletes or anyone dealing with fatigue or slow post-exercise recovery.
 

They’re rich in folate, iron, and fibre too, making them heart-friendly and digestion-friendly. Add them to smoothies, salads, or even baked dishes for a tasty and nourishing boost.

3. Dark Leafy Vegetables

Best ones like spinach, kale, collard greens, and Swiss chard are loaded with nutrients, and they’re naturally rich in glutamine too.
 

These greens help heal and strengthen your gut lining while also providing iron, magnesium, and fibre to energise and cleanse your body. Eating them regularly supports immune balance, fights inflammation, and promotes faster recovery from illnesses.
 

Whether you sauté them lightly, toss them into a green smoothie, or mix them into soups and omelettes, these greens keep your digestive system steady. Their combination of plant protein and glutamine makes them good for clean eating.

4. Oats

Oats are a warm, comforting way to start your day, and they also come with a hidden benefit—natural glutamine.
 

This whole grain supports muscle recovery and gut repair, especially when your body feels worn out from stress or heavy activity. Oats are also among the foods that raise serotonin levels healthily.
 

Oats are rich in soluble fibre, especially beta-glucan, which helps regulate blood sugar, lower cholesterol, and feed your good gut bacteria. This means oats also help maintain a healthy gut environment, where glutamine plays a key role.
 

Enjoy them as a bowl of oatmeal, overnight oats, or even added into homemade granola bars to keep your system energised and balanced all day long.

5. Chicken

This is one of the best animal-based sources of glutamine, making it a go-to food for people looking to build muscle, recover from workouts, or support their immune health.
 

Lean chicken breast, in particular, delivers not just protein but also a solid amount of glutamine to help with tissue repair and cellular regeneration.
 

If you’re feeling run-down or healing from an illness or surgery, including chicken in your meals can speed up the healing process.
 

It’s also incredibly versatile—grilled, baked, and shredded into soups or salads—making it easy to enjoy while fueling your body with what it needs to stay strong and active.

6. Fish & Seafood

Options like salmon, tuna, cod, shrimp, and crab are excellent sources of glutamine, along with other vital nutrients like omega-3 fatty acids, zinc, and vitamin B12.
 

These ocean foods help repair tissues, reduce inflammation, and keep your immune system strong. Glutamine from seafood also supports healthy muscle growth and brain function, especially when you’re under physical or mental stress.
 

Salmon and tuna are particularly rich, and their healthy fats help the body absorb nutrients better. Enjoy grilled fish with a side of vegetables or include shellfish in stir-fries or pasta dishes to get a tasty, brain-boosting, and body-repairing meal in one.

7. Egg Whites

These are low in fat and a good source of pure protein and glutamine. This makes the benefits of eggs ideal for people trying to build lean muscle, recover after workouts, or maintain gut health without adding extra calories.
 

Glutamine from egg whites helps reduce muscle soreness, aids in cell repair, and improves immune function. They’re easy to digest and quick to prepare, whether boiled, scrambled, or made into an omelette.
 

You can even mix them into smoothies or use them in protein-rich baking recipes. For people avoiding dairy or meat, egg whites are a light way to stay nourished.

8. Dairy Sources

Dairy products like milk, yoghurt—especially Greek yoghurt—cottage cheese, ricotta, and even hard cheeses are all good sources of glutamine. These calcium-rich vegan foods offer a double benefit: they provide both glutamine and calcium for bone strength.
 

Greek yoghurt and cottage cheese, in particular, are rich in protein and support muscle recovery and gut lining repair. Including them builds good gut bacteria while delivering a steady supply of energy.
 

Whether you eat yoghurt with fruit, add ricotta to toast, or enjoy a glass of milk after exercise, these dairy options are a tasty and nourishing way to support your body’s healing and strength-building needs.

9. Legumes

Options such as kidney beans, black beans, lentils, pinto beans, chickpeas, soybeans, tofu, tempeh, and soy milk are plant-based sources of glutamine and protein.
 

They are especially important for vegetarians and vegans who need non-meat options for muscle recovery and immune support. Glutamine from legumes helps the body during stress, injury, or after intense physical activity, all while aiding better digestion.
 

They also contain iron, magnesium, and folate, which support energy levels and brain function. Add them to soups, curries, salads, or stir-fries, and you’ll be feeding your body a well-rounded, healing meal that’s also rich in heart-healthy nutrients.

10. Nuts And Seeds

Some best ones, like almonds, peanuts, walnuts, cashews, and sunflower seeds, are tasty snacks and natural sources of glutamine.
 

They support your immune system, help repair tissues, and keep your brain and muscles working well, especially under stress. These small foods are also full of healthy fats, protein, zinc and magnesium.
 

A handful of nuts or a sprinkle of seeds over your breakfast bowl or salad can offer steady energy and help your body rebuild itself on a cellular level. Whether raw, roasted, or made into nut butter, they’re a delicious way to stay healthy.
 

Note: It's worth noting that while many plant-based foods contain glutamine, the concentration is generally higher in animal products due to their higher protein content.

Do Bananas Have Glutamine?

Yes, bananas have glutamine, but in relatively small amounts. One large banana contains approximately 231 milligrams (0.231 grams) of glutamine.
 

To put this in perspective, science suggests that supplemental L-glutamine doses of up to 14 grams per day may be effective for certain purposes. Therefore, you would need to consume a very large quantity of bananas to obtain a significant amount of glutamine.
 

So, if you are looking to significantly increase your glutamine intake through diet, it's best to focus on the foods listed previously, such as fish, dairy, eggs, legumes, nuts, and certain vegetables.

How Can I Increase My Glutamine Naturally? 5 Tips

Follow these tips to naturally increase your glutamine levels naturally:

1. Consume Fermented Foods: Some fermented foods, like yoghurt (especially Greek yoghurt with live and active cultures) and potentially other fermented vegetables in smaller amounts, might indirectly support glutamine levels by promoting a healthy gut. A healthy gut can optimise nutrient absorption and utilisation, which could influence amino acid metabolism.

2. Eat Healthy Regularly: Consistent intake of protein-containing meals throughout the day can help reduce poor digestion symptoms and maintain a steady supply of amino acids, including glutamine, for your body to utilise. Avoid prolonged periods of fasting if your goal is to support natural glutamine levels through diet.

3. Prioritise Fresh, Unprocessed Foods: Processing can sometimes degrade nutrients. Opting for fresh, whole food sources of protein and vegetables will ensure you're getting the most out of their nutritional content.

4. Stay Hydrated: Adequate hydration is crucial for overall metabolic function, including the transport and utilisation of amino acids.

5. Manage Stress: While not directly a dietary tip, chronic stress can impact the body's amino acid balance. Managing stress through techniques like exercise, adequate sleep, and mindfulness can indirectly support metabolic health.

The Final Say

While these foods contain glutamine, the amount you absorb and the impact on your overall glutamine levels can vary based on individual metabolism and other dietary factors. If you have specific health concerns or significantly increased needs (e.g., due to intense exercise or illness), consult with a registered dietitian to determine if dietary changes are sufficient or if supplementation might be considered (while keeping in mind the precautions mentioned previously).

FAQs

1. What is the best form of glutamine to take?

The most common and natural form is L-glutamine. Your body makes it, and it's found in foods. Supplements usually use this form. Some people think powder might be absorbed a bit faster than capsules or tablets.  

2. How to increase glutamate?

You don't usually need to increase glutamate directly through diet because your brain makes it. However, exercise can temporarily raise glutamate levels in your brain. Some supplements that boost GABA might indirectly affect glutamate.  

3. What causes high glutamine levels?

High glutamine in the blood can sometimes point to problems like liver issues because the liver helps process it. Too much glutamine supplement intake can also raise levels. In the brain, it is linked to imbalances with other brain chemicals or health conditions.
