Лада
Это не глютаминовая кислота - это глютамин, я имею в виду Jarrow.
И я бы не назначала глютаминовую кислоту (возбуждающий нейротрансмиттер, в больших дозах нейротоксин!), особенно без измерения аминокислот в крови, что я чаще вижу у этих детей - это как раз недостаток оппонирующего глютамина.
"Aspartate (в содовых напитках) and
glutamate act as neurotransmitters in the brain by facilitating the transmission of information from neuron to neuron.
Too much aspartate or glutamate in the brain
kills certain neurons by allowing the influx of too much calcium into the cells. This influx triggers excessive amounts of free radicals, which kill the cells. The neural cell damage that can be caused by excessive aspartate and
glutamate is why they are referred to as
"excitotoxins." They "excite" or
stimulate the neural cells to death.!!!!!!
Aspartic acid is an amino acid. Taken in its free form (unbound to proteins) it significantly raises the blood plasma level of aspartate and glutamate. The excess aspartate and glutamate in the blood plasma shortly after ingesting aspartame or products with free glutamic acid (glutamate precursor) leads to a high level of those neurotransmitters in certain areas of the brain.
The blood brain barrier (BBB), which normally protects the brain from excess glutamate and aspartate as well as toxins, 1) is not fully developed during childhood, 2) does not fully protect all areas of the brain, 3) is damaged by numerous chronic and acute conditions, and 4) allows seepage of excess glutamate and aspartate into the brain even when intact.
The excess glutamate and aspartate slowly begin to destroy neurons. The large majority (75 percent or more) of neural cells in a particular area of the brain are killed before any clinical symptoms of a chronic illness are noticed. A few of the many chronic illnesses that have been shown to be contributed to by long-term exposure to excitatory amino acid damage include:
* Multiple sclerosis (MS)
* ALS
* Memory loss
* Hormonal problems
* Hearing loss
* Epilepsy
* Alzheimer's disease
* Parkinson's disease
* Hypoglycemia
* AIDS
* Dementia
* Brain lesions
* Neuroendocrine disorders
