This is often due to a limited diet like vegan, certain medical conditions or the use of B12-depleting medications like metformin or proton pump inhibitors

The model suggests an exchange with glutamate, but no mitochondrial GABA/glutamate exchanger is known in mammalian cells, although an exchanger has been demonstrated in plants (Michaeli et al., Figure 7 An increase in aspartate but a decrease in glutamate and glutamine contents and synthesis has been observed in brain cortex from 17-day-old succinic-semialdehyde dehydrogenase-deficient mice together with a pronounced decrease (40%) in glutamine synthetase expression, whereas GABA production was virtually unaffected (Chowdhury et al., 3A,B follows that reduction of glutamate production, including initial transamination from -ketoglutarate might explain both the increase in aspartate content and the reduced glutamine synthetase expression

It works by binding to the GHRH receptor on the pituitary gland, prompting the release of hGH in a manner that closely mimics the bodys natural hormone rhythms
