L-Glutamine VS Glutamine

While used interchangeably, the terms L-glutamine and glutamine are different in certain aspects. Primarily, these compounds differ in terms of chemical structure.

L-Glutamine is an isomer of glutamine. As such, the arrangement of atoms in the molecule of L-Glutamine is slightly different from that of glutamine. Nevertheless, there is no significant difference between the said compounds in terms of health effects among individual users.

Micronized L-Glutamine VS L-Glutamine

Micronized L-glutamine is a recently manufactured form of L-glutamine which is characterized primarily as having finer particles. It has the same CAS number, molecular formula and molecular weight as that of the common L-glutamine form.

Many manufacturers prefer the use of Micronized L-glutamine as it is shown to have improved solubility and rapid absorbability. Thus, the body can absorb the product and use it more easily than the ordinary form of the product. Micronized L-glutamine is better and more advantageous.
