About This Product

L-glutamine is an essential amino acid and one of the building blocks of protein. When the body experiences a glutamine deficit, it can break down protein stores—like muscles—to get more of it.

Adding The Vitamin Shoppe® brand L-Glutamine Powder to your supplement stack can support protein synthesis and muscle recovery so you can keep flexing on your wellness goals.

Does the job, wish it was unflavored
Overall, it does the job and absorbs really well. The only downside is that it doesn't taste great at all, give whatever you put it in a strong plastic taste or something like that

Causes anxiety in some individuals.
I'm sure this works for other people but please use with caution. I didn't know it can cause anxiety and it gave me an awful panic attack that I had to go to the hospital for.

Great Product for Senior Dogs and Cats
my holistic vet recommended an l-glutamine supplement for my senior dogs who are starting to lose muscle mass, and one of them also has acid reflux/tendency for stomach ulcers. I've started using it with my cats as well. It isn't working miracles by any means, but I definitely think it is helping with muscle tone and has helped my one with her reflux. This is a very good value for this product and I will be buying it again.

This stuff is a miracle.
I used to suffer from extreme bloating. I used to look like I was 7 months pregnant after eating. Constant tummy aches and constipation. This stuff is a miracle! I have NOT been bloated once since using it. My tummy has flattened. I can?t believe I waited so long to use it.

mayte s
Is your L Glutamine vegan/vegetarian, free of heavy metals, fermented, heat treated? What raw materials were used? Thanks Maria
Maria B
Is this product (L-glutamine powder) vegan? What is it sourced from? Thanks.
Zach G.
Where is this product manufactured?
A shopper
this product will cause hair loss ? this product contains any testosterone boosters ?
A shopper

Best Answer:  No. It is an amino acid that the body readily produces in the lungs, but as always past the age of 25 the normal processes slows down. It aids in the healing processes, great for the immune system and when coupled with NAC N-Acetyl-L-Cysteine it produces L-Glutithione. I never heard about hair loss.

Constance M
what is this glutamine sourced from?
TYLER M
My trainer has be taking TwinLab's Amino Fuel in the morning, on an empty stomach. Would I take this in addition to that, but after my workout in the evening?
A shopper

  I'm not familiar with Amino Fuel. Is there glut amine in it? If so I wouldn't take a separate dose pre workout. I take 5mg pre workout, 5 mg post workout and 5 mg at bedtime.

Shelly B

  I'm afraid I don't know. You should ask a nutritionist.
