5-Hydroxytryptophan - Obtained from the plant Griffonia simplicifolia 
The African black bean Griffonia simplicifolia is naturally rich in 5-hydroxytryptophan (5-HTP). In the body, 5-HTP is formed from the essential amino acid L-tryptophan, which must be supplied in sufficient quantities through food. 5-HTP is also an amino acid which is a direct precursor of the messenger substance serotonin. Serotonin also has the nickname "happiness hormone", since this messenger substance is decisively involved in the regulation of well-being. Serotonin is also associated with the "sleep hormone" melatonin, which has an important influence on the regulation of sleep patterns. Biogena 5-Hydroxytryptophan 100 contains the important amino acid 5-HTP from Griffonia simplicifolia as a supplementary contribution to the body's own serotonin formation.

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.
