What is L Glutamine?

Glutamine from The Protein Works™ is selectively sourced to ensure only the finest quality Glutamine is used in our products. 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 and exercise, it is key in promoting muscle development and improving post workout recovery.


What are The Benefits of L Glutamine?

Glutamine is an amino acid that’s traditionally used by strength athletes wanting to increase muscle mass because of the role it plays in cell volumisation and in the creation of a positive environment in the body to build quality muscle mass. It has also, following impressive studies, been advocated by experts for use by athletes during periods of intense training because of its ability to support the immune system, prevent over training and enhance recovery.


Can L Glutamine Help My Recovery?

Firstly, to appreciate Glutamine's immune boosting properties you must first understand what happens to the body during periods of intense training. Whilst at rest your immune system functions efficiently, however research shows that when you train at an intensity higher than 85% of your maximum heart rate (near exhaustion), your oxygen usage vastly increases. This causes lactic acid to accumulate in the muscles, which in turn alters your PH and causes your body to pull alkaline reserves from bones and other mineral dense sources. Furthermore, muscle tissue is torn and muscle energy stores are depleted.

All things considered the body has a lot to cope with and this can result in an ‘immune system crash’ which is where the health of the immune system is compromised and can last anywhere between 3 to 72 hours. This is where glutamine can help since it’s been shown to improve the efficiency of cells and in turn help fight bacteria and viruses and ensure your immune system remains healthy even during periods of intense training.


Can L Glutamine Help Fat Loss?

Glutamine has also been found to be an excellent supplement for those looking to lower their body fat percentage and keep muscle mass at the same time. This is because not only does glutamine help to regulate blood sugar levels and therefore help you when dieting, but also it can help promote muscle development and prevent muscle breakdown. This is the main reason most bodybuilders will supplement their diets with glutamine when ‘cutting’ for a competition, since it enables them to reach very low body fat levels whilst at the same time maintaining the muscle mass they’ve built ‘off season.’


Why is Your L Glutamine The Best?

Here at TPW™, you can have supreme confidence in the product quality and supply source. Each ingredient supplier must pass rigorous audits and checks before being given the TPW™ quality seal of approval. Traceability, quality, and consistency are the three things we demand on every single ingredient. This is our philosophy that flows through every product we manufacture and sets us apart in the world of sports nutrition today.

Q. What is Glutamine?

A. Glutamine is the most abundant non-essential amino acid in the human body.

Q. When should I use Glutamine?

A. 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.

Q. What are main reasons for using Glutamine?

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

Q. What does Glutamine taste like?

A. Glutamine 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.

Q. Is Glutamine an essential or non essential amino acid ?

A. Glutamine is considered a semi essential amino acid as your body produces Glutamine.

Q. What are the differences between essential and non essential amino acids?

A. 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.

Q. Are there any specific health benefits associated with Glutamine?

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

Q. Is all Glutamine the same no matter what brand you use?

A. As with so many things in life, if you don't ask the right questions, you won't get the right answers! The quality of ingredient can vary significantly and therefore the potency will do too. In addition, just because a product may be called pure it doesn't mean that it necessarily is. We recommend you read the ingredients and nutritionals on the label to better understand exactly what you are buying. We can assure you that our products are 100% pure. At TPW™, we are committed to transparency and openness in all our products and that is why we provide a Product Profile on Glutamine which gives a complete overview of the product's background including our approval, location of manufacture and money back guarantee applicability.

Q. How can I tell if the Glutamine I buy is good quality?

A. Look for the Certificate of Analysis which will give you the assurance that what you are buying is what it says it is.

Q. Is Glutamine suitable for vegans and vegetarians?

A. Yes, it is suitable for both vegans and vegetarians.

Q. Can I use Glutamine with other supplements?

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

Q. What if any side effects will I get from taking Glutamine?

A. We haven't heard of any nasty side effects from taking TPW™ Glutamine

Q. Is Glutamine found in natural whole foods?

A. 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

Q. What effects should I expect from taking Glutamine alongside my training regime ?

A. 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.

Q. Who should take / benefit from using Glutamine?

A. Bodybuilders and strength athletes. Endurance athletes. Those new to weight training. People involved in team sports. Those who participate in regular intense training and exercise.

This is a great quality regular glutamine which has helped me by speeding up recovery and reducing DOMS mainly after hard leg workouts involving leg press, hack squats, front squats, stiff leg deadlifs, leg curls and leg extensions along with calves.

After that listed type of workout my legs normally remain sore for up to 3 days but using this product has allowed for the overall soreness to be reduced allowing for me to train legs on a more frequent basis Mon - Wed and Fri.

Great Recovery Product, Essential for adding to your post workout shake with a fast acting carb source such as dextrose or cluster dextrin and mix of proteins preferably an isolate straight after your workout.

The peptide version of this product has better absorption and is a superior version but does not taste as nice, if you are after the best then that would be the preferred option.

Says what it does really. I buy unflavored so i mix in into my protein powder. When i have it on it's own it still doesn't really taste of much. Unlike Glutamine Peptides which tastes quite foul.
Got the orange flavour. It ain't half bad.
Love this stuff, have never took Glutamine before until i ordered this stuff a month or so ago, and now i will never be without it, I used to suffer severe DOMS the next day, mainly with chest & legs, but now i feel no were near as sore as i used to be and I'm pushing harder in the gym each and every session, so if your going for a high volume leg day i highly recommend you start using glutamine, will be an absolute life saver in the long run!
Without a doubt the best tasting Glutamin! I went for Berry Blitz and it will be a regular purchase for tasty! Speedy always!
I train very high volume in a hybrid of strength and hypertrophy and this is drasticly changed my recovery,

for example when i train legs i do around 12 compound sets plus many isolation movements and this is very taxing on my body, i ache for 4 days with good diet but since i suplemented with 15grams of glutamine on training days and 5/10 grams on off days i barely even feel a ache...

Muscles are alot less tight/uncomfertable, im able to train harder and longer with shorter recovery

This is a must for anyone on a intense, high volume routine and suffers from DOM's

Bought the green apple spike to mix with a few unflavored products. Stack up my shake and it's awesome.
Tried the Orange Burst which tastes great. works well for during and post workouts. Tend to tip mine into a plastic container for storage as the powder does tend to get everywhere when you're trying to get it out of the bag. Will be repurchasing & would recommend. Another GF product too....
Bought orange burst and it makes gym water more enjoyable, at a good price why not?
A very nice product and a good buy.
I always buy unflavore. Great stuff for good price
berry blitz is lovely haven't been using it that long but have great expectations for this product
I picked up 1kg of Orange burst and thought i would give it a try. It took a little while to get use to the taste as i am not use to flavoured water but now i really like it. I often add this to other drinks and blitz in my blender with a glass full of ice to make a slush in the evening or after gym :) On longer workouts i'll sip this through the session.
I bought the flavoured version and I take 5g after training mixed with whey isolate 90 and some dextrose.I mix it with my supergreens on off days.great product and great value compared to other suppliers.
Great supplement, throw in 5g before and 10g after training. Works a treat
Great product, works a treat for after workouts

Go for Berry Blitz flavour, very good supplement and quick service.
I really like this supplement. It tastes fine and helps so much after a hard work out plus the day after the day after!
tastes amazin and gives you energy after the gym nothin better than this instead of fizzy drinks
Was sceptical of the benefits of glutamine as a DOMS reducer / minimiser. After the first week or so of use began to notice a measurable reduction is post workout DOMS - especially noticeable the day after the day after leg day! Need to make sure you use a dosage that relates to your body size though - lack of flavour is no problems - just mix with protein!
Bought the unflavoured 250g version to give it a go and am very happy with it. It mixes easily and is very good value considering other products on the market. Will hopefully be buying a larger pack next time!
Great value compared to everything else on the market, I add the unflavored to the all in one which already contains glute but topping up that will do no harm. All in all very happy with another great value product.
Its very good stuff and taste ok.........only problem I have is the scoop that comes with it holds 2.5ml and I take 5ml 3 times a day other issue is that the scoop gets stuff stuck all over it these are minor things but otherwise its decent.

I have the Apple Spike, great tasting, mixes well and does the job, this will be a regular order for me.
Use this in my post workout shake with whey 80 and dextrose. Good value for money and I always add in more than what is normally included in a pre blended shake.
Mixes well and can't complain about the price. Essential product .
An absolute must have amino , have tried both the flavoured and unflavoured version , unflavoured is fine when you throw into your recovery shake, mixes in no problem and you can never dispute the benefits of using glutamine. Good price and good quality .
The unflavoued seems to taint the taste of the protein its mixed with. didn't really feel the effects of the glutamine.

Feel like when I start my cut it will be more effective though
Add this in to my protein shake to help with my recovery and works just great. Fantastic value for money for such a high quality product, never have a protein shake without using this now
Great Product, Mixes really well, I have tried both orange and apple flavours and both are great.

1kg bags make this a great buy
No after taste, dissolves fully in fruit juice or water so there is no bitty scum at the bottom of your glass. Overall a great prodcut!
The berry tastes great!
Mixes just like a squash and can feel the results within a day or two.
Highly recommend this.
This product tastes lush, I got the apple flavour, have only used it for a couple of days thus far but it mixes easily and is yummy to drink.
I was advised to add glutamine to my PW shake by a PT. It certainly does seem to speed up recovery time for me. Great delivery and packaging as always from TPW.
Thought I'd give it a try-and needless to say I was not disappointed!! Mixes great, not gritty bits in the bottom etc. But most importantly recovery times are down a considerable amount so I'll be adding it to my pwo for a long time coming!!
Smells a bit weird and taste isn't amazing but I've been taking it for nearly a week and feel good. I find it mixes best if you use a fork rather than putting it in a shaker. My recovery seems to definitely have improved and I don't feel like I need those rest days every couple of days but obviously it's good to get a couple throughout the week.
Good product but I find it needs a lot mixing unlike the other tpw products I have used... But I'm guessing this is inherit of glutamine itself.
Excellent product - great for inclusion in your PWO shake.

Bought the glutamine hoping it helps a little with recovery as training a little harder coming up to competition. There is no evidence that it improves muscle size so dont buy it on that premise but has been shown to help with immune system, hydration and recovery.
TPW glutamine is pretty tastless which is good. Mixes fine.

I've always had Glutamine since I've been working out and tried lots of different company's the last company I tried is concidered to be one of the leading brands and the powder was clumpy. TPW is a very fine powder really impressed with it. Fine powder means quicker absorption :)

I was advised that the healing process of my muscles would be aided by the use of this by the friendly guy on the TPW twitter feed and so ordered it, it arrived the next day and I started using this in glutamine product in with my cheery b flavour whey shake and I can feel the benefits within a day - my muscles healed quicker and my cardio workouts improved - even setting a new pb today for 2.4km run - 16.15 !!
A great product - next order I may well order the "works' as this has glutamine added in - but I highly recommend this product - top product - top service
