Insulin Pen for Diabetics Contains Neuro-excitatory Amino Acid Says MSG Expert Samuels

(Answer to a question from an Aspartame Consumer Safety Network blog reader who wants to avoid all of the components of Aspartame and Neotame in her medications and diet.)
NovoRapid Penfill 100U/ML (insulin aspart) contains:
  • disodium phosphate dihydrate
  • glycerol
  • hydrochloric acid and sodium hydroxide if pH adjusted
  • insulin aspart
  • metacresol
  • phenol
  • sodium chloride
  • water for injections
  • zinc chloride
The pharmaceutical firm that produces this product refers to "Insulin Aspart" as the generic name of the drug.  However, I found the following on Wikipedia.
"Insulin aspart (marketed by Novo Nordisk as "NovoLog/NovoRapid") is a fast acting insulin analogue. It was created through recombinant DNA technology so that the amino acid, B28, which is normally proline, is substituted with an aspartic acid residue. This analogue has increased charge repulsion, which prevents the formation of hexamers, to create a faster acting insulin. The sequence was inserted into the yeast genome, and the yeast expressed the insulin analogue, which was then harvested from a bioreactor."
Therefore, this product definitely contains aspartic acid, a neurotoxic amino acid that has been found by neuroscientists, in animal studies, to act the same as does glutamic acid, and in an additive fashion with glutamic acid.  As you know, aspartic acid is approximately 40% of aspartame.
In addition, I note that the product contains a phosphate.  We have found that some MSG-sensitive people with little tolerance for MSG, including me, act similarly to phosphates.  Phosphates are known to leach calcium and magnesium, two minerals known to be involved in the metabolism of glutamate.  This may explain the MSG-type reactions.  I know that aspartame sensitive people react similarly from MSG, but I do not know if some react to phosphates.  I would suspect that they do. - Jack Samuels
