Serving Size & Timing

The suggested serving size for N-Acetyl L-Glutamine is between 500mg (1/4 tsp) and 1000mg (1/2 tsp) to be taken three times per day. N-Acetyl L-Glutamine works best when it is consumed on an empty stomach.

N-Acetyl L-Glutamine (pure powder)
Warning, for the faint of heart, it is rather tart, but I combine it with so many other Bulksupplement powders along with some Keifer and stevia that it is not a problem for me at all. My Dr. has asked me what I was doing for my skin, as it looked so much improved.... it's the Glutamine. My gut is healing as well. I do wish that it didn't require as large of a dose to get the number of grams in that I require daily right now, compared to some other brands, but because this is pure without fillers, flavors or colors, I can't complain. *

Great Addition!
I used this supplement for a trial period and i can definitrly say im better off WITH this into my daily routine! I feel like it only adds to my health and wellness along with my other daily supplementations. Taste is okay but im not taking a supplement for the taste, im taking it for the RESULTS! Two thumbs way up!*

Not a fan of this glutamine!!!!!!
Ok, first the disclaimers: Yes, is great and their products are awesome. I've been purchasing my supps from for several months now. No complaints. Second, I'm an avid user of Glutamine; 10-30 grams per day. I've been using the regular Glutamine powder without any problems at all. I highly recommend Glutamine. However, this product took me by complete surprise. BE ADVISED: The first thing that hit my like an underserved facial punching was the taste. I've had some pretty foul tasting supps in the past, but this was the absolute worst!! Seriously, and it will destroy the taste of you protein shakes as well. if that weren't bad enough, I've had diarrhea everyday since starting this product. Yesterday I only took 10 grams, and I was ok this morning. 20 grams later, and diarrhea's back. The other Glutamine didn't bother me at all, and I will reorder it. As for this one, I can't even finish it. I'll be throwing the rest away, as much as I hate to do it. *

N-Acetyl L-Glutamine
This product is fantastic. My mood is heightened and my muscles feel younger after taking this product in this form--very bio-available.

Glutamine is also good to help people in alcohol recovery to reduce cravings, especially when combined with a b-complex vitamin.*

Gut Repair
I use this in my post work out shake. This mixes well and has no taste. I liked this better than the L-Glutimine for these reasons. I also use this for my gut, which I can tell if I don't take. No bloating or discomfort.*

It's all about recovery
Being 42 now, it's a little different when it comes to being able to bounce back from the stresses of training and being healed and ready to go full force for the next workout. In fact most regardless of age focus only on the training and not the recovery process, which is where we make the gains. I notice faster recovery from workouts, soreness fading quicker, and just more energy when I use this product, especially before and after training. Excellent product you'll love it!!

Pre Work-Out Boost
Not only does this work as a pre-workout boost, it also helps to alleviate any lactic acid buildup by taking it after the workout! GREAT pure powder! Thank you!!!!!*

Glutamine Easy on the gut
I consume high levels of glutamine, and it can cause some stomach upset, but this one doesn't bother me at all. Very easy on the gut. *

n-acetyl l-glutamine prescription
My N.D. prescribed this product to alleviate severe fatigue and concentration problems, due to neurotransmitter dysfunction. It has been a great help for that as well as my workouts.*

N-Acetyl L-Glutamine
First of all, Bulk Supplements is far and away the best place to buy supplements. The prices, quality, and customer service are outstanding. I recently purchased this powder and I regularly use it in my pre and post workout drinks. I think it is a great product and I definitely notice a shorter recovery time. The bonus is that this powder is also vegan...that's extra stars in my opinion!*

Glutamine is an essential supplement that helps with muscle recovery before, during, and after exercise. Prevents muscle loss during cutting and helps to burn fat.*

Great Product
I just started using this a several days ago. I have heard it can help repair the lining of your gut and keep things moving. I can't say for sure but I think it's doing something positive for my digestive system. I have had less bloating and discomfort and am more regular. Great Product!*

This is the second time I bought this stuff. I used this while I had a injured hand from gymnastics and I swear I felt better the few days after taking this than I did with icy hot compresses. It also helped me maintain my weight while I'm stuck on the sideline. Try it you can't go wrong. *

Glutamine with a kick
Love this product! Recovery benefits like regular L-Glutamine with the benefit of fat burning properties and what feels like a little boost. Drink this in my workout mix with carbs and other energizers and feel like I can workout all day! Great stuff. *

N-Acetyl L-Glutamine (pure powder)
I purchased this product because of the statements on the website that it reduces fat and muscle breakdown as well as protects the immune system. I'm almost 3 weeks into a rigorous weight training/cardio schedule and I thought this supplement would benefit me. I've bought other products from Bulk Supplements and I keep coming back because they have the cleanest, best supplements that I can find!*

On 3/13/2015 Shelly said...

So far this product is starting to work for us with liposomal nutrients. We will keep using it with Glutathione and Lecithin. *
