Transport Technology

N-Acetyl-L-Glutamine (NAG) is the acetylated version of L-Glutamine, which is the most abundant amino acid found in skeletal muscle tissue. It’s more stable in water and metabolically efficient at delivering glutamine’s biological effects versus conventional glutamine or glutamine peptides. The efficacy appears to be even more pronounced for people on low-calorie diets — particularly low-carb diets, and the efficiency of the NAG form of L-Glutamine also means that it’s more easily metabolized, so you get more bang for your Glutamine buck.*

NAG can also play a significant role in increasing muscle cell volume, glycogen storage, and growth hormone production while simultaneously supporting the immune system. That’s a lot of good news because it means fuller muscles, increased energy, and improved overall health.

NAG is an extremely potent and versatile version of L-Glutamine that is a must-have for any serious athlete who isn’t willing to accept compromise.



Q: Why should I use this instead of regular L-glutamine? Is there really a difference?

A: L-Glutamine, in general, is a great addition to your supplement regimen, but NAG delivers more of the benefits you want because it’s more potent and efficient, and it’s more easily metabolized.*

Q: Since this is in powder form, can I add it to a protein shake?

A: You can add NAG to a protein shake, but keep in mind that it’s fruit flavored, so depending on the flavor of your protein, it could make for an odd combination. We recommend taking it separately because of that, but there’s no reason not to take them back-to-back.*

Q: If I want the most results possible, should I take NAG throughout the day, or is there a specific time that’s best to take it?

A: Thanks to its efficiency, you only need to take the one-teaspoon serving per day, and it’s best to be taken within 30 minutes of finishing your workout.*
