Magnesium L-Threonate: The magnesium form for focus & mental performance

Whether it’s making important decisions at work, long days of studying, or a daily routine that constantly demands full concentration – our brain achieves remarkable things every single day. That’s exactly why Magnesium L-Threonate is increasingly becoming the focus of scientific research. In a randomized, double-blind, placebo-controlled human study involving 100 adults, researchers investigated how Magtein® affects various areas of cognitive performance over a period of six weeks. After six weeks, the Magtein® group showed a greater change in the overall cognitive score compared to the placebo group:

  • Magtein®: +8.4 points

  • Placebo: +5.6 points

This is why BIOGENA Magtein® Magnesium L-Threonate stands out:

  • Original Magtein® – the scientifically researched branded ingredient

  • 155 mg magnesium per daily dose

  • 180 capsules for a convenient 60-day supply

  • Produced according to the highest BIOGENA quality standards
