What is Glutamine?

Glutamine is the most prevalent amino acid found in the muscles of the body. Considered to be a 'must have' supplement for those involved in intense training & exercise, Glutamine is a great choice for post-workout. Glutamine is the most abundant amino acid in your body. Synthesised internally, not from the food we eat, its not considered an essential amino acid.

However, in special circumstances, such as illness or injury, our body's utilization will outpace the demands. For example, in times of sickness the substantial amount of physiological stress causes a negative imbalance between the building and breakdown of muscle. As such Glutamine supplementation should be considered. Before you question your need to use this conditionally essential amino acid you should know glutamine has more tricks up its sleeve. 

Glutamine performs a number of roles including the support of muscle growth and fulling the cells of the immune and digestive system. Without it, muscle wouldn't regrow, our health would deteriorate and our digestive system would not be able to absorb the food we eat. Now you understand why it's the most abundant amino acid! When we exercise we place a significant amount of strain on the mentioned processes. Depleting our limited stores of glutamine increases our risk of under recovery. Poor recovery increases our risk of infection, meaning less training and a longer time to achieve our goal. 

When is The Best Time To Take Glutamine?

There are a number of way to supplement glutamine, it all depends on circumstance and purpose. In the instance of supporting muscular recovery, research has found 0.1-0.3g per kg of body weight capable of reducing delayed onset muscle soreness. In other words, if you weigh 80kg, taking 10g of glutamine post workout will negate the muscular ache we feel after pushing ourselves in the gym. 

In endurance athletes, taking 5g post workout will significantly reduce the occurrence of illness. For gut health benefits, supplementing 0.25-0.90g per kg of body weight 1 hour before running can reduce the occurrence of gut discomfort associated with endurance exercise. This supplement is no one-trick-pony, you just have to use it intelligently.

 If you’re looking to ensure you’ve got plenty of this amino acid in your system then supplementing via Glutamine Powder is a great option. Available in a variety of flavours specifically engineered in house by Protein Works, you will be spoilt for choice.

Your Questions, Answered.

It's the most abundant non-essential amino acid in the human body.

It depends on your lifestyle and goals, we recommend the following optimal serving times. Consume 15g daily. Usually servings are split into 3 equal servings of 5g in the morning, 5g in the afternoon and 5g before bed.

To restore glycogen levels, build new tissue and aid faster recovery after intense training and exercise. By adding this to your supplement regime, it increases the levels of glutaminc acid in the body, which helps metal focus and general mood.

It doesn't really have a taste when mixed in with a protein shake. If taken on its own then is can have a slight bitter taste, so is best mixed with a flavoured juice.

It's considered a semi essential amino acid as your body produces Glutamine.

There are in excess of 20 amino acids which make up all the proteins in the body. Between 9 and 12 of those are produced naturally by the body, and these are known as non essential amino acids. The other amino acids are not produced by the body therefore diet or supplements must be the source of those essential amino acids.

Studies have shown that supplementing with Glutamine can boost the immune system and prevent infection and promote healing.

Yes, it is suitable for both vegans and vegetarians.

The simple answer is yes. We recommend you always check serving instructions on each product if you plan on taking a combination of supplements.

We haven't heard of any nasty side effects from taking Protein Works Glutamine

Yes, it is naturally found in meat and dairy products, such as beef, pork and poultry. However, anyone who trains hard and heavy may require additional supplement intake of Glutamine to meet their body's requirements

Results vary depending on your diet, nutrition, training and individual body type. For an average individual, it helps the growth of lean muscle mass as well as muscle recovery.

  1. Accidentally bought, over the moon

    I accidentally bought the Berry Blast flavour instead of unflavoured, so I couldn’t add it to my protein shake. But I was able to add some unflavoured supplements (creatine monohydrate and BCAA), and the Glutamine acts as a really good carrier for masking the more bitter unflavoured products. Will be buying Berry Blast as part of my regular supplementation from now on.
  2. Worked fast!

    I had been doing research unrelated to exercise but linked to gut issues and glutamine came up as an aid for repair. (How do you repair your gut when you constantly use it caused more stress than my brain could handle!) so I saw it available on here and bought some along with my normal protein powder. I had one scoop in 100ml of water first thing in the morning about 15 mins before food, same at dinner time. Within 3 days after months of pain, the pain had gone and I feel better in myself energy wise on top of digestively and stomach feels flat . As I do weights this also may contribute to not aching as much but Ive not really concentrated on that as I’m overwhelmed with relief that I have had to do food intolerance tests to find the culprit. Great company that I trust the quality of products too. I had the unflavoured and it’s ok as I drink it down in one lol. It’s a bit like soluble aspirin flavour lol
  3. Love this

    I started taking glutamin when I started training several years back- I stopped and then one time I had an ulcerated flare up which stops me training really annoying but I took glutamin and I'm sold that glutamin can suppress my uc symptoms along with the repairing process after a heavy training session. I love glutamin.
  4. Great product

    I always use this product, very effective for maintaining gains and reducing catabolizing during heavy training sessions.
  5. Great in Berry

    I have recently got some of this in the Berry Blitz flavour as well as the other Apple and Orange flavours which i have not opened yet, i find the flavouring to have been improved with this product as well as the BCAAs over the years which makes this much nicer to consume on a regular daily basis, this is also one of the easiest mixing forms of glutamine that i have tried.
