What is L-Pyroglutamic Acid?
L-Pyroglutamic acid is a very unique amino acid that contains a 2-oxo-pyrrolidone base structure and is produced naturally in the body from the amino acid glutamine. It can also be found in our diets and plays a role in the glutamatergic system! Although L-Pyroglutamic acid is derived from glutamine, the truth is that they are not all that similar. In fact, L-Pyroglutamic acid is more closely related to the amino acid called proline and one of the alternate names for L-Pyroglutamic acid is actually 5-oxoPROLINE!
Although it can be found in foods such as meat and eggs, relying totally on getting enough L-Pyroglutamic acid from your diet is not generally enough. L-Pyroglutamic acid is necessary for bodily function and helps promote cognitive and metabolic functions while even supporting feelings of well being.
