Liposomal Magtein is Quicksilver Scientific’s brain-targeted magnesium: magnesium L-threonate paired with phosphatidylcholine and carried in a liposome, for cognition, calm and deeper sleep. One 450 mL bottle holds 30 daily serves.
How Liposomal Magtein Works
Most magnesium never reaches your brain. Magnesium L-threonate does — it crosses the blood-brain barrier, which is precisely what the ingredient was developed for out of MIT research. Once there it enhances neural plasticity, the process underneath memory, focus and learning, and it modulates the neurotransmitters that decide whether you wind down at night or lie there replaying the day. Quicksilver adds 450 mg of high-purity phosphatidylcholine per serve, the phospholipid your neuronal membranes are built from. The liposomal carrier does the rest: hold a dose in your mouth for 30 to 90 seconds and absorption begins there, through the mucosal tissue, instead of waiting on digestion.
Key Ingredients
Two actives, each with a distinct job:
- Magnesium L-threonate — the magnesium form clinically shown to cross the blood-brain barrier, unlike most magnesium on the shelf; it is what makes this a cognitive formula rather than a general mineral.
- Phosphatidylcholine — the phospholipid your brain cell membranes are made of, supporting both the membrane and the neurotransmission that runs across it. It also forms the liposomes that carry the magnesium in.
Who It’s For
This one is for the brain that will not switch off: the day that ends with a racing mind, the afternoon where focus slips away, the memory that used to be sharper. It suits you especially if you already take magnesium and have noticed it does plenty for your muscles and little for your head. Pair it with BrainGain when memory and focus are the main concern.
Suggested Use
Take one dose daily, and we would split it: 5 mL during the day and 10 mL one hour before sleep. Hold each dose in your mouth for 30 to 90 seconds before swallowing, and take it on an empty stomach where you can. Store at room temperature, and adjust as directed by your healthcare practitioner.
Frequently Asked Questions
What makes Magtein different from other magnesium? The form. Magnesium L-threonate crosses the blood-brain barrier, so it reaches the tissue where cognition and sleep are regulated — and that is not something every magnesium form does.
Can I take it alongside the magnesium I already use? Yes. Magtein is aimed at your brain, so it complements rather than replaces a magnesium you take for muscles or bowel regularity. Run your total intake past your practitioner.
Where do magnesium and sleep actually meet? Magnesium modulates the neurotransmitters that switch your nervous system between alert and at rest — the balance we describe in our article on GABA and glutamate. Magtein puts that magnesium where those signals are made.
