GLN is the only American Fermented L-Glutamine in the market.

Glutamine is the most abundant amino acid within the body and is primarily stored and synthesized within the skeletal muscle. L-Glutamine is a non-essential or conditional amino acid. This means the body can sufficiently synthesis enough for normal cellular activity in normal situations. But many times the body is put under great metabolic stresses, like heavy training exercise, that can deplete the body of its natural stores of glutamine. In these situations, glutamine becomes an essential amino aicd that needs to be supplemented, if the above stresses are apparent.


The manufacturing methods of amino acids are categorized as: 1) extraction from hydrolysates of animal or plant protein, 2) chemical synthesis, 3) fermentation, and 4) enzymic. Although DL-Methionine for feed additives use glycine, without an asymmetric carbon, are manufactured in a large scale by chemical synthesis, most amino acids are manufactured by fermentation and enzymic methods. Several amino acids including L-Leucine, hydroxy L-Proline, L-Tyrosine and L-Cystine are still being manufactured by extraction in addition to fermentation and chemcial synthesis.

The manufacturing process of an amino acid by fermentation comprises fermentation, crude isolation and purificatioin processes. In the fermentation process, the desired amino aicd is specifically produced by the fermentation microorganism. In the crude isolation process, most impurities contained in the fermentation broth are removed by combining various technologies. Final purification is performed to ensure the required quality for the intended use. The final product is obtained as a crystalline powder. The product is released only after quality tests have verified that the product meets specific requirements, and the normal functioning of each process step has been verified. All manufacturing processes for the production of amino acids for medical use must comply with current good manufacturing practice requirements.

As stated, most impurities are removed by the crude isolation process. The purification process is relatively simple and performed frequently. Careful performance of the fermentation and isolation processes, as well as the combination of these two processes, is critical to manufacture a high quality product with high productivity.

Why Fermented L-Glutamine is Best

Most glutamine supplements you see in the market are from shellfish, human hair, bird feathers etc., which not the cleanest source for L-Glutamine, as there will be measurable amounts of harmful, cancer-causing heavy metals such as lead, arsenic or mercury. But no glutamine powder supplement lists on their label where their glutamine comes from!

The best L-Glutamine in the world comes from a fermentation process of beets! That's right beets. Beets are fermented with probiotic cultures and the yield of that interaction is a 100% vegan sourced, fermented L-Glutamine. In fact Fermented L-Glutamine is so pure, it is the only form acceptable by use in hospitals.

You Get Exactly What You Pay For

GLN (Fermented L-Glutamine) is the purest L-Glutamine you can find. It's all vegan, non-GMO, free from impurities, heavy metals and hidden micro toxins. GLN is the ONLY L-Glutamine made to true 100% pharmaceutical standards. When you first start taking it, it will take a few days before you recognize the changes. These improvements will be subtle, but in a few days you will have more energy, some of the older aches and pains may start to dissipate, your memory might snap to attention more clearly and you might notice more pep in your step.

You might notice all of these benefits one day with the cheaper, inferior glutamine powders, but with GLN you WILL definitely see the improvements! Your body is the only you've got so treat it better than you would anything else and put only the very BEST into it!
