L-glutamine, an amino acid in free form, can turn into glutamic acid. Glutamic acid is the precursor of an important inhibitory neurotransmitter GABA (gamma-aminobutyric acid). L-glutamine also plays an important role in getting rid of ammonia.

I'm using this for my stomach and already after the first two days I started to feel a change!

I try this for leaky gut protocol. Trusted brand. Good packing. Great shopping in iHerb as they packed things nice and secure.

Corresponds to the description. The perfect item. Excellent packaging. Fast shipping

I have been using this product for a long time and am ready to leave your feedback! Every day, the whole family uses the products of this company. The best price and quality on the market! I advise everyone, you will not regret

I take four of these per day and it has really helped keep my IBS under control. I takes a while for it to work, doesn't happen overnight but there is a noticeable difference in my elimination habits.

No noticeable effect from taking this product. Definitely better quality brands available

good products, great range, fast shipping, thanks

I had other brands which I couldn't tolerate so well this one is more gentle

Glutamine seems to help my gut but too much causes my glutamate/gaba levels to get out of balance.
