L-Glutamine

About L-Glutamine

L-Glutamine is one of the most abundant amino acids working within the body. Amino acids are often described as the building blocks of protein, helping to support a wide range of everyday functions, from muscle repair and immune wellbeing to gut health and overall recovery.

L-Glutamine is classed as a conditionally essential amino acid. This means the body can usually produce it naturally, but during periods of increased physical demand, such as intense exercise, stress, illness or recovery, your body’s need for L-Glutamine may increase. In these situations, L-Glutamine supplements can be a helpful way to support normal levels and complement a balanced wellness routine.

What Are The Benefits of L-Glutamine?

L-Glutamine offers great support for your immune system, as your white blood cells use L-Glutamine to shield your body from infection.  

L-Glutamine can also help maintain a healthy gut by strengthening the intestinal cell barrier, thereby preventing damage.  

L-Glutamine may also enhance athletic performance; studies have found that L-Glutamine may reduce muscle soreness after high-intensity exercise and decrease the risk of athletes contracting illnesses following intensive exercise.  

What We Say...

 “The recent conversations around L-Glutamine and its potential benefits for boosting athletic performance are very interesting and it's definitely a promising supplement for those who exercise and train heavily to incorporate into their wellness routines”  

- Julia, Director  

Who Might Benefit from Taking L-Glutamine?

Athletes & bodybuilders: Taking L-Glutamine post-workout can aid in muscle repair and ease soreness, and is a great support of immune function during periods of heavy training and exercise.  

Those with digestive issues: L-Glutamine plays an important role in strengthening the cell barrier in your intestine. Using an L-Glutamine supplement helps strengthen the gut barrier and helps those with conditions such as irritable bowel syndrome.  

Hospital patients & trauma survivors: Those undergoing severe stress, trauma or suffering from burns will use up your stores of L-Glutamine far more rapidly than usual. Taking L-Glutamine can prevent muscle wasting, accelerate wound healing and can be a great option to reduce infections post-surgery or post-treatment.  

What is the Most Beneficial Way to take L-Glutamine?

L-Glutamine is most commonly taken as a convenient powder formula. Powers are a great way to have maximum control over your intake and are often well absorbed. 

Simply mix the powder into room-temperature or cold liquids. This makes it convenient to add to your daily routine; simply add to your water or juice, or blend into soft food such as yoghurt.  

It is important to avoid mixing L-Glutamine with hot liquids, as this can degrade the amino acid.  

We'd also recommend it on an empty stomach, typically before meals or at bedtime, as this helps your absorption.  

L-Glutamine Powder vs Capsules 

L-Glutamine supplements are commonly available as powders or capsules, and the right option will depend on your routine. 

Powder supplements can be a good choice if you want a more flexible serving size or prefer mixing your supplement into water, juice or a smoothie. They may also be better suited to those using L-Glutamine as part of a sports nutrition or gut health routine. 

Capsules can be more convenient if you want something quick, simple and easy to take on the go. They may suit gym bags, travel or busy mornings, although the serving size per capsule may be smaller than a powder. 

The best L-Glutamine supplement is the one you can take consistently and comfortably. 

What to Look for When Choosing an L-Glutamine Supplement 

To choose a high-quality L-Glutamine supplement, look for formulas that are free from unnecessary fillers, colours, artificial flavours and common allergens where possible. 

For those with dietary needs, many pure L-Glutamine powders are suitable for vegan and vegetarian routines, but always check the product label if you have strict dietary requirements or sensitivities. 

L-Glutamine isn't the right choice for everyone. If you have a medical condition, are pregnant or breastfeeding, taking medications or other supplements, you may wish to check with your health care provider before adding any new supplements to your routine. Alternatively, get in touch with our team of experts for insights and advice.
