BIOGENA SPORTS - L-Glutamine Sticks 5000
L-glutamine: building block of muscle tissue
L-glutamine is the main component of the pool of free amino acids in the blood plasma with a quantity share of about 20 %, whereby the highest concentration can be found in the muscles. Glutamine is therefore one of the most important amino acids in the human body and, as a building block of muscle tissue, it is significantly involved in protein synthesis, but also represents an important substrate for the cells of the gastrointestinal tract. During intensive training, the content of L-glutamine can decrease considerably, which is why supplementation can be helpful for people who want to optimise their training performance.
BIOGENA SPORTS L-Glutamine Sticks 5000 provides glutamine in its bioidentical L-form and is therefore an optimal source for additional intake to the daily diet and the body's own synthesis. Our premium raw material meets the highest quality and purity criteria. The L-glutamine is produced in a complex manufacturing process through the fermentation of glucose - the result is a vegan raw material with a purity of 99-100 %, which BIOGENA offers as a training companion in a high dosage of 5 g in practical READY-TO-GO sticks.

Why high-dosed L-glutamine powder after exercise?
|
During exercise, your body breaks down amino acids in the muscle tissue – a process called catabolism. Glutamine is the most abundant amino acid in muscles and is often depleted after training. Since the body does not produce enough on its own, and replenishing glutamine stores through food is often impractical directly after training, supplementation makes sense. Taking it helps replenish amino acid levels after your workout and thus supports your recovery. Whether strength or endurance athlete – L-glutamine is a go-to training buddy and also ideal for vegetarians and vegans. |

FAQ
Glutamine powder is an amino acid especially popular with active individuals. It supports muscle recovery, promotes protein synthesis, and strengthens the immune system.
In addition, glutamine has a positive effect on your digestive system by supporting gut health. This helps your body recover faster after stress and at the same time improves your well-being.
You should take BIOGENA SPORTS glutamine powder preferably directly after training or on intense days when your body especially needs recovery. Ideal intake is on an empty stomach to optimize absorption.
This way, you effectively support your muscles in recovery and at the same time strengthen your digestive system – perfect to stay fit and high-performing.

Whether glutamine powder or capsules are better depends mainly on your personal preferences and lifestyle. Powder scores points with flexible dosing and fast absorption – perfect if you need higher amounts or like to mix the supplement into shakes. Capsules, on the other hand, are practical for quick, tasteless intake. For intense training and targeted recovery, many athletes prefer powder due to the higher dosage and versatility. |

Glutamine and L-glutamine essentially refer to the same thing, but the difference lies in the chemical form. L-glutamine is the biologically active form of the amino acid that your body can use directly. In short: L-glutamine is the form that really matters – exactly the one you’ll find in high-quality supplements like BIOGENA SPORTS. |
Yes, L-glutamine powder can expire. Like all dietary supplements, it loses potency and quality over time. Therefore, always check the expiration date on the packaging and store the powder in a cool, dry, and dark place.
That way, its purity and effectiveness are preserved as long as possible.
After the expiration date, we recommend no longer using the product to ensure optimal results.
At Biogena, “pure substance principle” means that we do not use technological additives which are used for the fully automated manufacturing of tablets, capsules and pills (e.g. anticaking or release agents and so forth) or additives that are used for optical reasons or for enhancing the taste of the products (artificial aroma, colouring agents, coatings etc.). Due to a semi-automatic manufacturing process, we can avoid these substances that often have a higher proportion in customary products than the actual active ingredients. In the case of nutritional supplements, additives have to be indicated in the list of ingredients. Here, the patient or customer can get useful information. Concerning the single ingredients, we also care for our raw materials to be free of carrier substances. In cases where this is not possible, we use natural food components such as maltodextrin, cellulose powder or calcium carbonate. The majority of our ingredients is produced exclusively for us – free of carrier substances (e.g. our enzymes our probiotics: other manufacturers often use lactose as a carrier – the product batches produced for us are explicitly without carriers).
