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.

A Higher Standard of Liposomal Delivery with QDS®️

The Quicksilver Delivery Systems®️ signature trademark sets our liposomal products apart from other companies and ensures high absorption and bioavailability.

Our products' clear consistency can only be achieved with liposomes that are small (20-100 nanometers) and stable enough to pass between cells. These small vesicles begin absorbing as soon as they hit your mouth, so you can get high absorption of the product before the harsh processes in the digestive system alter it.

Remember, not every liposomal supplement is created equal. Quality, chemistry, and manufacturing practices matter.
