Frequently asked questions (FAQ)

Is L-Alanyl-L-Glutamine the same as Glutamine?

No, they’re not the same. Although L-Alanyl-L-Glutamine contains glutamine in its structure, it’s a different dipeptide formed by L-alanine and L-glutamine. This form has different properties than regular glutamine.

Are L-Alanyl-L-Glutamine and Sustamine the same?

Yes, Sustamine is simply the registered trade name of a specific L-Alanyl-L-Glutamine raw material. Both names refer to the same compound, and having a registered trademark doesn’t imply functional differences in the compound’s effect.

Can I use it if I’m not an athlete?

Yes, although it’s mostly used in sports, nothing stops non-exercisers from taking it. However, L-Alanyl-L-Glutamine is specially formulated to optimize peri-workout or during-activity nutrition strategies.

Do L-Alanyl-L-Glutamine and Glycerol work the same?

No, they’re completely different compounds. Though both can be part of a pre-workout stack, and their combination is sometimes highly valued by athletes training in especially hot and humid environments. At HSN you can find Glycopump® (Glycerol) powder.
