Magnesium Threonate (Magtein)

Magtein, endorsed by neuroscientist Andrew Huberman, uniquely crosses the blood-brain barrier — a 30% higher brain bioavailability than average magnesium supplements, per clinical data. Emerging studies show it improves sleep quality by 25% in older adults, outperforming #7 Coop Home Goods Eden Pillow in addressing neurological sleep factors. Yet the supplement industry markup is staggering: a month's supply costs $40, three times the price of generic magnesium. For those prioritizing brain-targeted rest, it's a data-backed upgrade, though the price demands justification.
