Latest info on L-Glutamine
In response to several customers mentioning that they are running short of L-glutamine, I contacted Jon who contacted Jarrow formulas (the supplier of this supplement) about the problem some are experiencing. The full discussion thread can be found here:
But I wanted to also post to this discussion forum as not all people follow the discussion in the RFLB "Group" and tend to use this board more. Here is a copy of the findings about what is happening if you run short on L-Glutamine:
Here is Jarrow's response to Jon:
"The product isn't being underfilled. I'm sure of this. I have run into this in the past on numerous occasions. There is more than the claimed weight in the container, based on my own personal experience of having weighed many of these containers. The problem is in the dispensing of the material. Please see the attached letter I wrote to a consumer some time ago as this goes into the issues regarding the scoop and the L-glutamine material. This is definitely not a new issue and it obviously isn't going to go away, unfortunately.

Here is the letter which John O'Connor from Jarrow references in the above email response. He is writing to another customer who had a similar inquiry about the servings per package issue:
"Dear Patty,
I understand and appreciate your concern. I have checked with our Purchasing Department as well as our Research & Product Development Department and here is what I was able to find out. The 5 cc scoop in our Glutamine 113.5 gram bottle is intended to provide an approximate measure per serving. Generally, glutamine material is very soft and fluffy, and doesn’t pack neatly in the scoop. Also, the density of the material may vary from batch to batch. The L-glutamine powder does not exhibit the free flowing characteristic apparent with some other powdered materials. Unfortunately, without anti-caking agents, this makes it difficult to measure a fixed weight with a scoop.
Nevertheless, your concern is a legitimate one and one we felt needed addressing. Therefore, our R&D people, using a 5 cc scoop, recorded several measurements of our L-glutamine powder on an analytical scale. What they found was that there was notable variance from scoop to scoop and that the amount of material taken by this scoop does yield a weight of 2 grams or more. Depending upon how the material settled with each scoop that was measured, one scoop weighed anywhere from 2.0 to 2.8 grams. This finding could possibly account for the fewer number of servings per container that you have experienced.
Moreover, besides the nature and variable density of the material, I was informed by our Purchasing Department that we are also limited by the types of commercially available scoops, which is an issue for powder products, in general, owing precisely to the different densities of these different materials, and this product in particular, due to the characteristics described above. In the case of the glutamine powder, R&D estimates that a scoop of 4.4 to 4.7 cc would be ideal for a 2 gram serving. However, the next available smaller size that they have been able to find is 3.5 cc, which is not really any more desirable because it tends to scoop less than 2 grams of material.
Please understand that I am not trying to make excuses; rather, per your inquiry, I am attempting to explain the issues that are affecting the consistency of the serving size. Unfortunately, the scoop is a crude measuring tool and not as precise as we would like. I hope you can understand the conundrum that our people have had to deal with in attempting to offer a product that can be conveniently measured in grams as accurately as possible (using a volume instrument) by the consumer who, in all likelihood, is without the luxury of the more expensive and cumbersome but accurate analytical gram scale.
This having been said, please be assured of the fact that there is no intentional misrepresentation on our part and that the product does provide 113.5 grams of L-glutamine per container, as claimed. Moreover, if one could precisely measure the 2 grams, this would yield 56 servings per container.
And although probability is low, we will make every effort to find the scoop size that will most consistently yield 2 grams of L-glutamine per serving. We will also deal with making the customer aware of the varying weights by indicating on label that scooped powder weights -- particularly powders of this nature -- are approximations.
Thank you for your understanding.

The main thing that's bugged me personally with the Glutamine is ... the clear scoop in a white bottle of white powder! I cannot see the da...ed thing! Solved it this morning by painting a little red nail-polish on the tip of the handle! Problem solved. The only remaining issue is that the scooper handle is a bit too short to reach the bottom of the plastic jar ...

I am going through the RFLB for the second time. Having run low the first time on L-glutamine I decided to buy extra this time. Iherb sells it fairly cheap in the 1000gr container. That way lots of Glutamine and no worries. I am actually getting better results this time than the first time and I am using a 5G scoop from a different supplier but still using the Jarrow formula. I really think the extra Glutamine was actually needed in my case and the other 5g scoop has a much longer handle and that makes things much easier.
I was off for a while due to some injuries and put back on my old weight and a little bit but I am back now trying to lose a lot of weight before a DR trip to someones wedding.
I should probably post my method of making Jon's egg and meat meal from the worst meal in the program to one of the best.

Definitely post that recipe! We'd love to see it.
.... and glad to have you back

Well here you go. I remember the first time many people complaining about the original recipe probably mostly because they mixed the egg whites with the meat and then cooked it which makes a big gooey mess and doesn't taste that good.
Here is what I do instead.
Cook the ground beef and the egg whites separately. Stir the egg whites while cooking them to give them a scranbled egg appearance. Once they are cooked add the cooked ground beef. Then take a couple of tablespoons of the salsa that you use for the other recipes and add that to the mixture. Finally I add tumeric and a chile powder to the mix to taste. The ones I use are Chipotele Chile powder and Smoked Habenero.
It ends up tasting like chile but with eggs instead of beans. I look forward to eating it every time.
Enjoy!

Close to what I do, I brown the meat then stir in the egg whites and scramble them together. Then add whatever spice tickles my fancy that day.

The chile powders, (you can use Cayenne too) add an extra dimension since they also help to raise your metabolism and burn more fat.

For this recipe (which has always been my favourite one), I usually season the meat in spices before hand. Then I cook the beef first, set it aside. Scramble the eggs, and add the beef back in.

The thing that bugs me with the L-Glutamine is the shape of the bottle. It's not a bottle designed for scooping (more for spooning, if anything). As it is, once the volume of powder gets low, you can't even get the scoop out. You have to use 2 fingers to retrieve it . . . and then you have to tilt the bottle on its side to scoop it.

I actually buy the 1000G bottle from Iherb and I use the scoop from another brand of L-Glutamine. It has a much longer handle and therefore works much better. With the extra product there is no fear of running out before the 3 weeks finish.

Yeah, But it is still Jarrow brand right? So we just have to live with what they produce. Maybe Jon can fix these issues if he starts producing this as well?

Yes. I still use the Jarrow brand but the with the 300G one you run the risk of running out and with the 1000G bottle you have no problem. Still the scoop handle is very tiny on the Jarrow brand so I use the scoop from another brand.
