Ajinomoto® Glutamine is unparalleled in quality as it is produced by the world leader in amino acid research and manufacturing.

Ajinomoto® produces the purest and most bio-available amino acids in the world, due to their unique patented manufacturing process and 100% non animal origin.

Their pharmaceutical grade micronised Glutamine pioneers the way in sports supplementation and is also being administered by many leading hospitals around the world. Made from sugar beets which are fermented with probiotic cultures, also makes it a 100% vegan fermented L-Glutamine.

Glutamine is the most abundant single amino acid in the blood and in the muscle tissue. Glutamine concentrations have been shown to fall after an intense workout, as nitrogen carrying Glutamine is taken from muscle tissue and organs and is then used to support immune function and recovery.

This fall in Glutamine creates a catabolic environment for muscle tissue. Glutamine supplementation has been shown to support immune function, decrease inflammation and protect muscle cells from the damage caused by hard workouts.

Studies have shown that Glutamine may assist with:

  • Increased glycogen uptake  (Bowtell et al, 1997)
  • Stimulation of protein synthesis (Rennie, 1994)
  • Support gut health and immune function (van Acker et al, 1999)


Ingredients: Pure Pharmaceutical Grade L-Glutamine

    Great for Immunity

    Posted by on 03 Oct 2016

    I got onto Professional Whey as I'm a David Pocock rugby fan and after reading about the various products decided to try the Ajinomoto Glutamine to see whether it actually worked. I've used it since March 2016 and this is the first winter where I have not had a cold or caught a flu from working in a large office and catching public transport unlike other years. I can only attribute this to the glutamine which I take with BCAA's immediately after a 6-7km hill run or 30 mins of park sprints which seems to reduce the DOMS the next day, and I don't take any other protein powders apart from these 2 products. It mixes really easily with water or fruit juice which is great when I don't feel like dairy etc after a hard run, especially in summer. I will continue to use this product as it seems to work wonders with my immune system in my subjective opinion.

    My Favourite Product

    Posted by on 01 Oct 2016

    My body responds really well to this product. Whenever I come off it I always lose 2-3kgs, but then put it right back on when I get it again. This doesn't happen for any other glutamine supplement I've taken either, so I put it down to the quality of ajinomoto. So I always have this now - if I have nothing else I always have my glutamine. I have a litre water bottle and I always put a teaspoon of ajinomoto glutamine in there when I fill it up for a steady release all through the day.

    Fantastic product with great results!

    Posted by on 10 Aug 2016

    This is now the only Glutamine product that I use! I Glutamine loaded for two weeks on this product (5 times a day) and found it helped trim my waistline completely and eliminated the leaky gut problem I was having. I really needed to add a quality glutamine to my diet to help balance out my system. Love that it has no added sugars or fillers. Definitely will be buying from Professional Whey for life! I have used quite a few of their products now and I have found them all to be exceptional! Thank you Professional Whey!

    Get out of the Whey !

    Posted by on 15 Jun 2016

    It's kind of hard to know where to start with Professional Whey. I use a number of their products and have done so for a few years now. I'm satisfied with all of them, but Ajinomoto Glutamine stands out for me. I work long hours on my feet and as a result, developed major strain and pain in both feet and legs. So I started using Ajinomoto and Taurine as per instructions on the packet. The results were astonishing and fast. So started adding Leucine and Beta Alanine to my breakfast shakes as well, along with some flavourings. I've noticed a significant improvement to my condition and overall health, so much so, that I can now stretch effectively and exercise / train on my days off. Prices and delivery are ok. Good on you Professional Whey, I got back a part of my life I thought I had lost.

    Great quality

    Posted by on 07 Jun 2016

    Ajinomoto is known to be one of the best amino acid manufacturers in the world. Most "branded" supplement houses use this anyway so you might as well get it at an amazing price directly. Mixes well and is a staple must in any supplement regime for recovery.

    Great Product

    Posted by on 08 Mar 2016

    Great product that mixes well. Especially noticeable after intense training sessions, as it significantly reduces recovery times. Highly recommended.

    I really prefer this Glutamine to the cheaper type. The taste is a lot more subtle, and it mixes more easily. One real benefit that I've noticed is just a stronger immune system. I don't get colds anymore. My recovery time is greatly reduced, and it helps with digestion as well.

    DAILY ESSENTIAL: A daily vitamin of a supplement

    Posted by on 14 Jan 2016

    I take it for sooooo many reasons and I do believe that it is supplement worth taking. If I could only have 1 or 2 supplements on a dessert island...this is one of them.

    Long before I got into fitness, I was recommended this as I am a celiac. It is to help repair the lining of my intestines. My son was also recommended it by a Naturopath due to his dairy intolerances. So that is the first reason to note!

    #2 NOW we are all mindful to add it to our protein shakes, as we are fitness focused. The website surely describes all of the fitness benefits for taking this.

    However, reason #3 - helps to stimulate glutathine - one of the most important antioxidants that there is. Mopping up free radicals and staying young....this is therefore again, another must!

    #4 Japanese Doctors use it. How often do you read about Japanese doctors giving so-called "sports supplements" for ill people in hospital? They usually only prescribe medications that are proven to work. I read scientific research that Japanese doctors give this supplement in hospital to patients and their recovery is much faster - weeks faster. So whenever my husband is unwell - this supplement is his preference. He actually FEELS better and he doesn't take hardly any supplements at all as he doesn't believe that they work. But he is convinced that this supplement does, along with Vit C and a multi. They are the only supplements he will take - as he doesnt believe any others actually work.

    I like to take supplements that show with scientific evidence that they live up to their claims, and I am convinced that this one does.

    It is really a supplement that we don't have to be without at these prices- and this japanese product is the best of them all; the most purest pharmaceutical grade in the world. It is the BMW of glutamines.

    I love it, and have used this for 7 years now, to keep us in top shape, and health - for the entire family.

    Because it seems to work for our family, we continue to buy it.

    PLEASE NOTE **CONSUMPTION - it can be difficult for the body to digest/absorb, so I take it 1/2 hr before food on an empty stomach, first thing in the morning. And you must not have hot drinks when you have this supplement either.

    Apart from that one minor inconvenience, the benefits are numerous....

    One bag lasts us 6-12 mths. You only need 1/4 tsp on an empty stomach first thing at night, and the last thing before bed, is a cheap and effective health supplement for longevity/add to your antioxidant arsenal, fitness and sports supplements and general health wellbeing protection and recovery.

    I take this to aid my recovery so I can train more frequently and with a high intensity. It certainly helps me recover better and my results are the proof. I would recommend this to anyone wanting to optimise their training and get the most out of it.

    Best I've Tried

    Posted by on 10 May 2015

    I have tried a few different glutamine supplements, but this is the best I have found by far. Only taking 10 grams around my workouts, plus my BCAA's and recovery times are much better after the big sessions. I will continue using this product, and can't recommend it highly enough
