    BULK POWDERS™ Glutamine, part of our Pure Series™ range, is the purest Glutamine powder available, and at a price that puts other brands to shame.

    Glutamine is one of the most popular products in the Pure Series™ range. Its popularity stems from the fact that Glutamine is the most abundant amino acid found in muscle tissue. Glutamine is a conditionally essential amino acid; this means that during specific periods (such as exercising) the body uses more Glutamine that is being synthesised.


    • Pure pharmaceutical grade Glutamine Powder
    • The most abundant amino acid in muscle tissue
    • Conditionally essential amino acid


    Glutamine is suitable for those exercising regularly or intensely who are looking to increase their dietary Glutamine intake.


    I'm bodybuilding: How can glutamine help me?

    Glutamine can be a very effective supplement for bodybuilders. Glutamine is the most abundant amino acid within muscle tissue, however when you train, glutamine levels can be significantly reduced as muscle tissue breaks down – even more so with the bodybuilding style of training. Supplementing with Glutamine (in particular post-workout) can allow you to restore the depleted Glutamine levels.

    What is in glutamine powder and why does the body need it?

    Glutamine powder is 100% L Glutamine, which is a conditionally essential amino acid. This means at certain times, this amino acid is needed from the diet, as the body cannot synthesis enough to replenish levels. One of these occasions is after you work out – training causes muscle glutamine levels to deplete to a point where the amino acid becomes conditionally essential. Consuming L Glutamine Powder will provide your body with a rich source of Glutamine that will help to restore muscle glutamine levels.

    Do I take glutamine before or after workouts?

    Glutamine is best consumed post-workout to help restore depleted muscle glutamine levels.

    What's the connection between glutamine and amino acids?

    Glutamine is a conditionally essential amino acid, this means that during certain periods (such as post-workout) it becomes essential to be consumed in the diet, as the body cannot synthesise enough to meet this deficiency.

    Will I have to adjust my diet plan to take this product?

    No, Glutamine is a free form amino acid, therefore does not have a specific calorific value. Simply add it to your post-workout shake, or throughout the day to support recovery.

    Combining Glutamine with a fast-acting carbohydrate such as Waxy Maize Starch may help shuttle Glutamine to the muscle cells faster. This is ideal for after exercise when your muscles are craving amino acids.

    Glutamine is complementary to many other products, ranging from other amino acids such as Instantised BCAA to other products such as Complete All in One, Pure Whey Protein™ and Complete T-Booster.

    Would recommend to anyone that does intense cardio and wants to maintain muscle mass. Review by ScottT
    Basically, I'm a courier cyclist part time whilst at university and so this means I will be out cycling for around 30-40 hours a week, with not a lot of rest, and when I first started, I lost a lot of muscle mass, because I was giving myself rest from work, and not going to the gym. But I wanted to get the gains back, so I decided to up my food intake, my protein intake, and started experimenting with other supplements, such as creatine, but these supplements had no effect, but since taking glutamine, it is by far the best thing that has helped me maintain and rebuild muscle mass all over the body, I've also seen a reduction in body fat since taking it.

    Absolutely BRILLIANT for "dodgy tummies" (also with hangovers!!) Review by Michelle Kickham
    This stuff is MAGIC when it comes to dodgy tummys - cramping, bloating, nausea.. and other things we don't like to list on the internet!

    I'm Coeliac and so I have a funny tummy - it gets upset very easily and I'd get bloated/crampy when I ate (and even If i hadnt...). Since I've started taking glutamine, this has almost completely faded away. Glutamine does line the stomach - I knew that - but I didn't know it would work so well!

    It's worked so well that my mother - who's on a lot of medication for a back trauma - started taking it to prevent the pains she gets from the tablets. She wasn't able to keep anything down, and had been prescribed an anti-nausea tablet (basically one to "line the stomach") - but it didnt work. I told her about Glutamine - and eventually she tried it one morning. She now buys the 1kg bag from you guys (along with Spirulina - I am very proud of my mother!!!) and has had absolutely no stomach pains since she took that first scoop.

    I HIGHLY recommend this to anyone with a funny tummy or a tendency to get bloated easily, or has issues with anything related to digestion.

    Oh, and for a hangover cure... take one full scoop in water about 1 hour before you start to drink. I'm not advocating drinking here... but just sayin... if you want to avoid the "vodka tummy"... try this.

    As always - amazing products and a fraction of the price in stores (I used to buy glutamine in a health food shop... it was 25euro for 100g.... extortion!)

    Love you guys! (Posted on 29/07/2016)
    fab stuff Review by lovemykitties
    I make a litre bottle of the apple and lime flavour (which tastes fab) and sip on it during my workout and finish the remainder post workout. I cant say it has reduced muscle soreness for me, but it is so much nicer than plain water and helps me get more fluids in post workout too. (Posted on 15/03/2016)
    Tastes sour Review by owen
    Opened up my first order of Glutamine and mixed with some whey, it made the shake very sour, not sure if its because of the mix will try on its own next time, overall very happy with the service keep up the good work BP. (Posted on 02/09/2015)

    Great Review by Joca
    Although it really smells and tastes not too good, it accomplishes its purpose. No muscle soreness after taking it, and also I thought that I became more relaxed and calm. I´m definitely going for more of it!! (Posted on 02/09/2015)

    Glutamine Powder Review by Anonymous
    I dont normally write reviews, however I strongly feel that this is the best glutamine powder I have ever used. I have been using glutamine supplements for the last 8 years, 5 years of which i was a professional rugby player.
    It has always helped with my recovery and reducing muscle soreness, however with BP's glutamine I am noticing an even bigger improvement in hypertrophy, muscle repair and speed of recovery from training.
    What's more this glutamine is THE CHEAPEST without fail, and trust me I have looked everywhere! £17.99 for 1kg? I have previously paid nearly thrree times this price! Cannot recommend this product enough and I'm hoping BP's other products (I'm trying their beta alanine next) prove just as good, if so they have a customer for life! (Posted on 02/09/2015)
    Excellent!!!!!!! Review by VLASIOS KIRTSIDIS

    it works. Review by alexia dobinson
    I haven't taken this for about 2 weeks now, purely because I ran out, the difference in my recovery is huge, I'm 40, haven't trained on a regular basis for some time, but I have been pretty much back in the groove for 7-8weeks now, and for 4 weeks I used L Glutamine, with porridge oats (ultra fine) and protein in a morning and evening shake, and since not having it for two weeks I'm struggling, I'm ordering some now!
