Description

Glutamine is considered the most abundant amino acid in the human body.

The reason for this is that glutamine serves as the ultimate energy supplier for rapidly dividing cells.

We deliberately avoid glutamine peptides derived from wheat protein and instead rely on vegan, free L-glutamine.

Our L-glutamine powder is available in a 500 g bag and belongs to our PURE range, which means it is free from additives and consists exclusively of L-glutamine.

What distinguishes our glutamine powder?

Our L-glutamine powder is derived from plant-based fermentation. We deliberately avoid glutamine peptides made from wheat protein to be able to offer a pure and vegan product.

Glutamine is part of our PURE Series, which means that only what is stated on the packaging is included: 100 % pure L-glutamine.

  • 100 % free L-glutamine
    Our L-glutamine powder comes from plant-based fermentation and is therefore vegan. It can be easily stirred into drinks and is therefore very simple to integrate into everyday life.
  • No gluten source
    We completely avoid glutamine peptides from wheat protein. This makes our product gluten-free and also suitable for people with gluten intolerance.
  • No additives & flavourings
    Our L-glutamine powder contains no flavourings or other additives. It consists of 100 % pure L-glutamine and is therefore free from any artificial ingredients.
  • Heavy metals analysed
    We have our L-glutamine powder regularly analysed by independent laboratories for heavy metals, including arsenic.

    The results of these tests are available in our database, so you can be sure that you are using a safe and high-quality product.

These properties make our L-glutamine powder an ideal choice if you are looking for high-quality, pure glutamine for your nutritional supplement.

Whether you want to buy L-glutamine to support your gut or use L-glutamine powder for your wellbeing – you will find a product that meets the highest quality standards with us.

What is L-glutamine?

Glutamine is one of the amino acids that is most abundant in the human body.

This amino acid plays a central role as an energy supplier for rapidly dividing cells, such as stem cells.

Glutamine serves both as fuel and as a building block for cells, making it an indispensable part of human metabolism.

Glutamine is particularly important for immune cells and intestinal mucous membrane cells. These cells use glutamine as their preferred energy source, which supports their function and regeneration.

Due to these properties, glutamine is of high relevance for the gut and the immune system.

Glutamine as an amino acid and its significance

Glutamine is not just a simple amino acid, but fulfils numerous important functions in the body. It is crucial for protein synthesis, which supports the building and maintenance of muscle mass.

Furthermore, it plays a role in regulating the acid-base balance and nitrogen balance in the body.

Increased glutamine requirement

During training or stress, the need for glutamine increases.

In such phases, the body may not be able to produce enough glutamine itself, which is why supplementation can be helpful.

Especially during intense physical exertion or in the recovery phase after illness, taking L-glutamine powder can help promote recovery and wellbeing.

Glutamine for the gut

Glutamine is particularly important for the gut. It supports the integrity of the intestinal barrier and promotes the regeneration of intestinal cells.

There is also evidence that glutamine can counteract inflammatory processes, which could play a role in Leaky Gut Syndrome, for example.

L-glutamine as a dietary supplement

Buying L-glutamine can therefore be a sensible decision to ensure that your body is always adequately supplied with this important amino acid.

Our PURE L-glutamine powder is an excellent choice if you are looking for a pure, additive-free supplement.

It provides you with a high-quality source of this essential amino acid.

How much glutamine do we need?

A high glutamine requirement arises from infections, sport or other intense physical exertion.

In such situations, the body's need for glutamine increases significantly to meet the demands of the immune system and muscles.

Glutamine plays an important role in building and maintaining skeletal muscle, especially in nutritionally critical situations.

We mainly obtain glutamine in the form of glutamic acid through food. In the body, this exists in dissociated form as a salt, glutamate.

Via glutamine synthetase, which essentially serves to detoxify ammonia in the body, glutamate (glutamic acid) is converted to glutamine.

During intense physical activity or stress, the body's own production of glutamine may not be sufficient to meet the increased demand. In such cases, taking glutamine as a dietary supplement can be beneficial.

Especially in the PURE form, like our L-glutamine powder, which comes from plant-based fermentation, you can be sure of getting a pure and high-quality product.

L-glutamine supplementation can be an effective method to ensure that your body is adequately supplied during times of increased strain.

Buy L-glutamine: Glutamine powder from the PURE range

Our glutamine powder contains exclusively free L-glutamine. It can be wonderfully stirred into drinks and is therefore very flexible to use.

We deliberately avoid glutamine peptides. For some time, it was assumed that peptides had a better effect on muscles because glutamine, as a free amino acid, is quickly metabolised by intestinal cells, for example.

This assumption is no longer valid today. An abundant glutamine intake will also adequately supply the muscles without the need for glutamine peptides.

Plus: Glutamine peptides are conventionally derived from hydrolysed wheat protein, which we firmly reject because wheat peptides are definitely not healthy.

Our L-glutamine powder is free from such peptides and offers you 100 % pure and gluten-free glutamine from plant-based fermentation.
