The Quicksilver Advantage
Unlike most magnesium supplements, Magtein (magnesium L-threonate) is clinically proven to cross the blood-brain barrier. Paired with Quicksilver’s advanced liposomal delivery, it delivers superior absorption, targeted cognitive support and fast-acting benefits. We’ve supercharged brain function by adding 450 mg of high-purity phosphatidylcholine (PC) per serving—a vital phospholipid for neuronal membrane support and healthy neurotransmission. The powerful combination of Magtein + PC helps fuel cognition and neuroplasticity supporting long-term brain health. Elevate your mental game with Magtein + phospholipids delivered in a liposome—an unmatched formulation for brain performance and mental well-being.
