To support balanced electrolyte levels, for the musculature and blood pressure

Potassium and magnesium: Essential micronutrients for the blood pressure and musculature
The important minerals magnesium and potassium work closely together and are directly dependent on each other: Thus, potassium supports the uptake of magnesium into the cell, while a low magnesium level and its loss leads at the same time to a reduction in the potassium concentration. As a well-experienced team, the two minerals contribute to maintaining normal muscle function. In times of increased nutrient requirement, for example during sporting activities, magnesium can contribute to the electrolyte balance. Potassium, as the most common cation (positively charged ion) within the cell, plays a role in maintaining normal blood pressure. Biogena RythmoPlex® contains both potassium and magnesium in physiological dosages and meaningfully supplements the daily intake of this essential micronutrients.

Physiological importance of the vital substances contained:
• The minerals magnesium and potassium support the normal functioning of the muscles
• Magnesium is important for the electrolyte balance
• Potassium plays a role in maintaining normal blood pressure

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.
