They both cause ammonia. Newport has the experience with working with his father for the complications of the Benzo drugs, he could better tell you how long the toxins stay in the body.
It's not just the Benzo drugs, they are just one of the sources. What it all points to, is the ammonia not being able to be converted as it should- and it, along with other toxins, bypassing the liver and staying in the blood stream.
I hadn't understood that the two, L-Ornithine and the L-Aspartates needed to both be taken..L-Ornithine for converting the ammonia, L-Aspartates for converting the glutamine. I thought it could be one or the other, and was just looking at the ammonia. Luckily, I had gotten the Magnesium/Potassium Aspartates (with Taurine) that Newport had pointed out to me from http://www.iherb.com,
and have been taking the L-Ornithine with them, plus I just got a Calcium Aspartate too.
It wasn't until I had a definite brain reaction to L-Glutamine, 3 times, that I figured out the ammonia/glutamine connection (and killing Lyme's co-infections, which produce ammonia neurotoxins)
From Andrew Cutler's book "Amalgam Illness"
>>>Glutamine should not be taken by those who have elevated blood ammonia. Those with notable liver problems should ask their physician about the likelihood they have elevated blood ammonia before taking it.<<<
>>>If you feel bad after taking glutamine or creatine you may have problems with the bacteria and yeast in your intestines making too much ammonia.<<<
