Glutamine

Shop Glutamine Supplements at Myprotein

Glutamine is the most abundant amino acid found in muscle tissue and plays a key role in protein metabolism. As a conditionally essential amino acid, your body can produce it naturally, but during periods of intense training or physical stress, demand may exceed supply.

Whether you're looking for l-glutamine powder for easy mixing or convenient capsules for on-the-go supplementation, our glutamine supplements are designed to fit seamlessly into your daily routine. Available unflavoured or in a range of flavours, they offer flexible options for every preference.

Who Glutamine Supplements Are For

Glutamine supplements are popular among athletes, bodybuilders, and regular gym-goers who follow structured training programmes. Many people who engage in high-intensity or endurance exercise choose to add l-glutamine to their supplement stack alongside protein powder and creatine.

If you're following a demanding training schedule or simply want to ensure adequate amino acid intake, glutamine powder or capsules offer a convenient way to supplement your diet. They're particularly popular with those who train multiple times per week or follow calorie-controlled nutrition plans.

When to Use Glutamine

Glutamine can be taken at various times throughout the day depending on your routine. Many people prefer to take l-glutamine powder post-workout, mixed into their protein shake or recovery drink. Others split their daily serving, taking half in the morning and half after training.

For powder forms, simply mix your chosen serving with water, juice, or add it to your existing shake. Capsules offer an even more convenient option if you prefer a ready-measured dose. Timing is flexible, so you can incorporate glutamine supplements into whatever schedule works best for you.

FAQs

What is glutamine?

Glutamine is a conditionally essential amino acid and the most abundant amino acid found in human muscle tissue. While your body can produce glutamine naturally, it's classified as "conditionally essential" because during periods of intense physical stress or training, your body's demand for glutamine may exceed its ability to produce it.

L-glutamine supplements provide this amino acid in its free-form state, ready for absorption. It's available as glutamine powder or capsules, with powder forms typically offering 5g per serving that can be mixed into drinks or shakes.

What's the difference between glutamine and l-glutamine?

The terms "glutamine" and "l-glutamine" are often used interchangeably in supplement products, but there is a technical difference. Glutamine exists in two forms: L-glutamine and D-glutamine. L-glutamine is the form found naturally in foods and produced by your body, and it's the biologically active form used in protein synthesis.

When you see "glutamine" on a supplement label, it almost always refers to l-glutamine, as this is the only form used in sports nutrition products. D-glutamine is not used in supplements and has no nutritional role in the body.

How do I take glutamine supplements?

For l-glutamine powder, mix your chosen serving (typically 5g) with 250-350ml of water, juice, or add it to your protein shake. The powder is unflavoured and mixes easily without affecting the taste of your drink. Many people take it post-workout by adding it directly to their recovery shake.

If you prefer glutamine capsules, simply take them with water at your preferred time of day. Some people split their daily serving, taking half in the morning and half after training, while others take their full serving at once. Timing is flexible, so find what works best for your routine.

Can I mix glutamine powder with protein powder?

Yes, glutamine powder mixes well with protein shakes and is commonly added to post-workout drinks. Because most glutamine supplements are unflavoured, they won't interfere with the taste of your protein shake. Simply add both powders to your shaker with water or milk and mix as normal.

This combination is popular among gym-goers who want to consolidate their supplementation into one convenient shake. You can also add other supplements like creatine or BCAAs to the same drink if desired.

What's the difference between glutamine powder and capsules?

The main difference is convenience and dosing flexibility. Glutamine powder offers precise control over serving size and can be easily mixed into drinks, shakes, or smoothies. It's also typically more cost-effective per serving and comes in larger quantities.

Glutamine capsules provide pre-measured doses that are convenient for travel or when you're short on time. They're ideal if you don't want to measure powder or carry a shaker bottle. The l-glutamine content is the same, so choice comes down to personal preference and lifestyle.

How should I choose a glutamine supplement?

Start by deciding whether you prefer the flexibility of powder or the convenience of capsules. If you regularly make protein shakes or smoothies, glutamine powder is an easy addition. If you're frequently on-the-go or prefer not to mix drinks, capsules might suit you better.

Consider the serving size and total quantity you need. Larger tubs of glutamine powder (500g-1kg) offer better value if you use it daily, while smaller sizes or capsule bottles work well if you're trying it for the first time. All our glutamine supplements contain pure l-glutamine without unnecessary additives.

Can I take glutamine with other supplements?

Yes, glutamine is commonly taken alongside other sports nutrition supplements. Many people include it in their stack with whey protein, creatine, and BCAAs. There are no known interactions between glutamine and other standard workout supplements.

You can mix glutamine powder directly into your protein shake along with creatine, or take it separately at a different time of day. Some people prefer to take BCAAs during training and add glutamine to their post-workout shake. The flexibility of glutamine supplements makes them easy to incorporate however you prefer.

What makes l-glutamine powder easy to use?

L-glutamine powder is micronised, meaning it's processed into extremely fine particles that dissolve quickly and completely in liquid. This makes it easy to mix into cold water, juice, or shakes without clumping or leaving a gritty texture.

The unflavoured nature of glutamine powder means it won't alter the taste of your drinks, making it virtually undetectable when added to flavoured protein shakes or smoothies. You can also take it on its own mixed with water if you prefer a simple, no-fuss approach.

How do I store glutamine supplements?

Store your glutamine powder or capsules in a cool, dry place away from direct sunlight and moisture. Keep the container tightly sealed when not in use to maintain freshness and prevent the powder from clumping.

Avoid storing glutamine in humid environments like bathrooms or near sinks. A kitchen cupboard or pantry works well, as does a drawer in your gym bag if you prefer to keep your supplements with your training gear. Proper storage will help maintain the quality and effectiveness of your l-glutamine supplement throughout its shelf life.
