What is a magnesium complex?

A magnesium complex is a combination of different magnesium compounds designed to optimally supply your body with magnesium. Various organic and inorganic magnesium forms have different solubility and absorption pathways — a complex with multiple compounds ensures especially efficient uptake in the body.

What are the benefits of a magnesium complex?

A magnesium complex combines different forms of magnesium, providing an optimal nutrient supply with a range of benefits. By blending various magnesium compounds, the body can absorb and utilize the mineral more effectively.

What makes the BIOGENA 7 Salt Magnesium Complex special?

BIOGENA 7 Salt Magnesium combines seven optimally absorbable magnesium compounds in a highly tolerable formula — perfect for sensitive individuals. Thanks to pH-independent absorption, magnesium is efficiently utilized. And the best part? Our sustainable eco-friendly can shows that quality and environmental awareness go hand in hand.

When should the magnesium complex be taken?

The magnesium complex can basically be taken at any time of the day. It is recommended to take it outside of meal times.

Can magnesium and vitamin B complex be taken together?

Yes, vitamin B complex and magnesium are generally safe to take together. In fact, this combination can be beneficial, as magnesium supports the metabolism of B vitamins, and both nutrients contribute to the proper function of the nervous system and energy metabolism.

Can magnesium capsules be opened?

Yes, the capsules can be opened and the contents stirred into water or juice. This is especially practical for those who have difficulty swallowing capsules or want to adjust their magnesium intake individually.

Is 7 Salt Magnesium suitable during pregnancy and breastfeeding?

Yes, magnesium plays a crucial role during pregnancy and breastfeeding, especially to support muscles, nerves, and energy metabolism. 7 Salt Magnesium can contribute to optimal magnesium supply in this phase. If unsure, consulting a healthcare professional before use is recommended.

Is a magnesium complex good for sleep?

Absolutely! Magnesium plays a key role for your nervous system. It activates GABA receptors — the little relaxation switches in your brain that help you unwind in the evening. Studies show that good magnesium supply can stabilize your central nervous system, strengthen your stress resilience, and help prevent sleep disturbances. A high-quality magnesium complex can be just what you need for more restful nights!

What is the difference between BIOGENA 7 Salt and BIOGENA SPORTS Magnesium?

BIOGENA 7 Salt Magnesium Complex contains seven different magnesium compounds to ensure good magnesium supply, as the solubility of each varies depending on pH. It is ideal for people with sensitive digestive systems.BIOGENA SPORTS - Magnesium Sport is specially developed for athletes and also contains seven magnesium compounds tailored for athletes plus activated vitamin B6. It supports muscle function, electrolyte balance, bones, and mental function, and contributes to normal protein and glycogen metabolism. It also helps compensate for magnesium losses through sweating.

What distinguishes the different forms of magnesium?

Each magnesium compound has its own unique properties. Whilst magnesium oxide, for example, is notable for its high magnesium content, magnesium citrate is considered to be particularly bioavailable – and magnesium bisglycinate, in turn, is regarded as particularly gentle. By combining seven different forms, the Siebensalz® Magnesium Complex ensures a well-rounded supply of magnesium.

How much magnesium is there in one capsule?

The Siebensalz® Magnesium Complex provides you with 140 mg of magnesium per capsule. With the recommended daily dose of two capsules, you will consume a total of 280 mg of magnesium.

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).

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.

7 Salt Magnesium Complex – 7 Forms, Maximum Absorption

How well your body takes up magnesium depends on the solubility of its different forms. Here’s the twist: your digestive system features varying pH levels—from acidic in the stomach to more alkaline in the colon. The more alkaline it gets, the harder it is for some magnesium types to dissolve and be absorbed properly.

Our premium Magnesium Complex blends organic and inorganic magnesium forms in a smart way, ensuring your body can absorb them efficiently—no matter the pH level. What does that mean for you? Thoughtful magnesium support that truly makes a difference!
