Magtein is the patented, proprietary form of magnesium that supports healthy magnesium levels in the brain by facilitating delivery across the blood–brain barrier. In a range of studies, including human clinical trials, it has been linked with improvements in brain health, cognitive vitality, and sleep quality.
This research base helped attract the interest of Arnold’s Pump Club – Schwarzenegger’s global health and fitness community, which formed an official partnership with Magtein last year. Today, the unique magnesium form features on @schwarzenegger – the star’s official Instagram account, which has 26.7 million followers. The science-forward carousel makes the case for Magtein— proof that strength isn’t the only thing worth training smarter.
Rory Lipsky, EVP, Magtein (ThreoTech, LLC) said: “It’s an absolute honor to have Magtein platformed like this. We’re obviously delighted that our patented magnesium is being placed in front of an engaged fitness and wellness audience of millions. But even more importantly, it’s a reflection of the scientific evidence that we’ve built up over the past decade. The Pump Club is built on a commitment to science and transparency, and only backs products that stand up to scrutiny, so this is a really meaningful endorsement for Magtein.”
To date, five peer-reviewed, randomized, double-blind, placebo-controlled human trials exploring Magtein’s benefits have been published. At SupplySide Global (Wednesday, October 28, 2026, in Las Vegas) ThreoTech, LLC, the commercial team behind Magtein, will host a breakfast briefing on an upcoming clinical study examining its benefits in athletes.
In addition to holding GRAS approval in the US, Magtein is approved as safe for use in consumer products in Canada, Japan, Turkey, India and Thailand. Since November 2024, it has also been available in the EU, and it was authorized as a novel food in the UK this year.
