Supports blood formation, reduces fatigue & exhaustion

Folic acid in activated form
Folic acid belongs to the group of B vitamins and is also known as vitamin B9. Natural sources include especially whole grain products, legumes and green leafy vegetables such as spinach or lamb's lettuce. Folic acid is a heat-sensitive and water-soluble vitamin. Therefore, vitamin losses can occur when food is prepared or stored for a longer period of time. Folic acid is involved in a number of metabolic processes in the body, such as the conversion of homocysteine into methionine. The branded raw materials Quatrefolic® and Extrafolate-S® contained in Folic Acid 800 contain folic acid in activated form as high-quality 5-methyltetrahydrofolate. These compounds can therefore be absorbed particularly easily and are directly available to the organism, as they do not first have to be converted into the active form. Folate plays a role in cell division and blood formation and contributes to the reduction of tiredness and fatigue. This vitamin is also important during pregnancy, as it is essential for the growth of maternal tissue. In this special phase of life, the need may be increased. Sufficient intake should therefore be ensured. Folic acid 800 from Biogena contains 400 µg calcium L-methylfolate (Extrafolate-S®) and 400 µg 5MTHF-glucosamine (Quatrefolic®), two folic acid compounds in activated form.

Production of our premium preparations

When it comes to quality assurance, we at Biogena make no compromises. In the production of our micronutrient preparations, we always pay attention to the highest standards - for complete traceability and a fully transparent value chain: from raw material sourcing and product development through studies and application monitoring to state-of-the-art in-house production, logistics and shipping to over 60 countries around the world.

  • Careful in-house production to a unique manufacturing standard at BIOGENA Good Health World in Koppl near Salzburg, including show production
  • High-quality and sustainable branded raw materials labelled with test and quality seals
  • Each individual batch undergoes the strictest quality tests by the German LEFO Institute Dr Wichmann, where experts independently assess parameters such as impurities, pesticides and heavy metals 
  • Certified according to ISO 22,000:2018, GMP - Good Manufacturing Practice, BIO certification, Halal certification, Kosher certification
  • Use of the purest capsule shells in the world: Vcaps® Plus and DRcaps® are purely plant-based capsule shells made from hydroxypropyl methylcellulose and nothing else.


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).
