What beverages can L-Glutamine be mixed with?

It’s a great question to ask, especially if you want to get the best results from your L-Glutamine.

Which drinks to avoid?

So the first thing to know is you should avoid mixing it with anything HOT.

  • So that means no hot drinks, like coffee or tea.
  • As well as no hot foods like soup or broth for example.

And the main reason for this, is that hot temperatures can potentially denature or damage, the amino acids.

Which drinks are best for glutamine powder?

So the main drink we recommend is water. It is the perfect delivery vehicle for your precious amino acids. Our suggested use directions are to mix 1 scoop or 5 grams of L-Glutamine powder, with 8 fluid ounces or 240 mils of water.

Of course, if you don’t love the light naturally fermented flavor of glutamine, then you can mix it with flavored beverages.

  • Vegetable or low sugar fruit juice
  • Or if you want to get fancy even something like a chilled iced tea
  • A fruit smoothie can also work

Now with all that said, there is one cold beverage you should avoid mixing it with. And that is any drink that contains a lot of protein. For example, a protein shake.

That’s because we don’t want the additional amino acids in protein, such as glycine, competing with our glutamine for uptake and absorption in your GI tract.
