Q: I am interested in trying my 26yr old son on GABA.

He has a totally controlled epilepsy, on Tegretol, but has a tendency to early sleep 'startles', like a tendency to have a mild seizure.

What dose would you suggest for GABA and is it worth trying please?


A:Taking a GABA amino acid supplement is not worth it, especially when your son is already on Tegretol.

Tegretol or Carbamazepine affect the GABA receptors in the brain, so taking more GABA, is still not going to get through. GABA may not even cross the blood- brain barrier.

The body actually synthesises its own GABA from glutamate using glutamic acid, another non-essential amino acid which occurs in proteins. Due to the fact that glutamic acid is "non-essential", the body actually recycles this amino acid. Therefore, it doesn't really matter if the diet is low in dietary protein as the body can create its own.
