Different micronutrients for the nerves and L-tryptophan
Tryptophan together with phenylalanine, tyrosine and histidine are considered aromatic amino acids and cannot be produced by the body itself. As a result, tryptophan is an essential amino acid. Our body is unable to produce this amino acid, which is why L-tryptophan, the so-called essential amino acid, needs to be taken in through food. In addition to this amino acid, Biogena L-Tryptophan 250 also contains different vitamins and minerals, which mainly have an impact on the “nerves”. For example, folic acid, magnesium and other micronutrients contained therein, support the normal psychological functions. The “nerve vitamins” B6 and B1 mainly have an impact on the nervous system. L-Tryptophan 250 also contains niacin, which contributes to reducing tiredness and signs of fatigue. As a result, the nutrient spectrum contained in Biogena L-Tryptophan 250 not only contains the essential amino acid L-tryptophan that cannot be produced by the body itself, but also selected substances to support “strong nerves”.

L-Tryptophan 250:
• Contains the essential amino acid tryptophan in the bioidentical L-form
• Magnesium, vitamin B6, vitamin B1 and niacin contribute to the normal functioning of the nervous system
• Folic acid, magnesium, vitamin B6, vitamin B1 and niacin promote the normal psychological functions
• Folic acid, magnesium, vitamin B6 and niacin contribute to the reduction of tiredness and signs of fatigue

All products


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).

Biogena cooperates with respected physicians and therapists in many different countries. With them, you are in good hands. You can also buy our products from our Biogena stores in Vienna, Linz, Salzburg, Graz, Natternbach, Freilassing and Frankfurt (Germany) as well as online at www.biogena.com.
