How do amino acids support sleep?

Amino acids are not only building blocks of body structures – they are also essential for the production of neurotransmitters. In this way, they take on important tasks in the nervous system and influence our sleep-wake rhythm. Selected amino acids such as glycine or L-tryptophan can help to calm down, support the falling-asleep phase, or accompany normal sleep. They act like little helpers that gently guide the body into relaxation mode.

Which amino acids for sleep?

Particularly relevant for good sleep are the two amino acids glycine and L-tryptophan. Glycine helps your nervous system to calm down – a factor that is important for relaxed falling asleep. L-tryptophan, on the other hand, is a precursor of the happiness hormone serotonin as well as the sleep hormone melatonin – both closely linked to inner calm and healthy sleep. In combination, the two amino acids unfold their full potential for the night.

How much glycine for sleep?

In studies, 3 grams of glycine per day were often used to achieve a sleep-promoting effect. However, individual perception and tolerance may vary. Anyone who wants to consciously integrate glycine into the evening should pay attention to a targeted and verified dosage – as in the BIOGENA Amino Sleep Trunk, which is precisely tailored to this.

What distinguishes the Amino Sleep Trunk from other amino acid drinks?

The difference lies in the quality and the composition. The Amino Sleep Trunk not only combines the two important amino acids glycine and L-tryptophan, but also meaningfully complements them with plant-based classics such as ashwagandha and hops – both traditionally associated with sleep and relaxation. In addition, there are the micronutrients magnesium and vitamin B6, which contribute to the normal function of nerves and psyche. The product is vegan, lab-tested, free from genetic engineering – and was developed together with physicians. Not a simple evening drink, but a well-thought-out amino acid drink for your conscious evening routine.

Where are BIOGENA preparations manufactured?

BIOGENA preparations are carefully manufactured in our own production facility, BIOGENA Good Health World (Salzburg, Austria), to a unique manufacturing standard. We are certified according to FSSC and GMP - Good Manufacturing Practice and have organic, halal and kosher certification. The quality-tested raw materials come from premium brand raw material manufacturers - sourced directly from the world market leaders.

Where can I buy BIOGENA preparations?

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 Austria (Vienna, Linz, Salzburg, Graz, Natternbach), Germany (Freilassing, Frankfurt, Düsseldorf, Munich, Hamburg) and soon in London (UK) as well as online at www.biogena.com.

What does the term “pure substance principle” mean?

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).
