Magnesium supplementation is common, yet many users report gastrointestinal upset and poor absorption, especially with single‑form products such as magnesium oxide or citrate.
Multi‑Salt Strategy Aims to Improve Absorption
Biogena, an Austrian company founded in 2006, markets its 7 Salt Magnesium Complex as a response to these issues. The product blends seven magnesium compounds—malate, bisglycinate, citrate, oxide, glycerophosphate, gluconate and carbonate—each of which dissolves at different pH levels along the digestive tract. By providing a spectrum of salts, the formulation seeks to maintain absorption regardless of individual stomach acidity, a claim supported by the company’s internal research, including the Good Health study, one of Europe’s larger micronutrient investigations.
The mix is intended to reduce the stomach irritation often linked to magnesium oxide or citrate alone. Users who have switched from those single‑salt supplements report fewer episodes of nausea and describe smoother digestion, along with anecdotal benefits such as better sleep and fewer muscle cramps.
Manufacturing Controls and Purity Claims
Biogena produces the complex in its own Salzburg facility, adhering to what it calls the “pure substance principle.” The capsules contain no artificial colourants, anti‑caking agents, nanoparticles or other unnecessary excipients. Independent laboratory testing of each batch is reported, and the operation holds FSSC 22000 certification as well as GMP and HACCP compliance.

Because the exact ratios of the seven salts are kept proprietary, competitors have struggled to duplicate the product precisely. In Austria and Germany, the supplement is frequently recommended by doctors and therapists, and the brand reports that roughly 30 000 health professionals across Europe trust its offerings.
Customer feedback reflects high satisfaction: the overall Biogena line scores 4.7 out of 5 on Trusted Shops, while the 7 Salt Magnesium Complex itself holds a 4.85 rating from more than 1 000 reviews, primarily on German‑language sites. The formulation is identical for buyers in the United Kingdom, though reviews there are less numerous.
Logistics are efficient within Germany and Austria, but shipments to the UK or other European markets may arrive one to two days later than domestic alternatives. Stock shortages can occur because the product is manufactured in small batches, and subscription discounts are limited to Germany, Austria and Switzerland.
For a long‑distance cyclist who needs reliable electrolyte support without mid‑ride stomach upset, the multi‑pH absorption profile could prove advantageous. Similarly, someone who has abandoned standard magnesium citrate due to nausea may find the blend’s tolerability a practical solution.
