Approach: The human outcome. Palette: C, Natural.

A close, low-angle shot of a sleeping person's bare forearm and hand resting on a rumpled white cotton duvet, a matte black smart ring on the index finger, with a small electric green LED glint on the ring's inner edge.

In the background, out of focus, are a wooden nightstand with a glass of water and the blurred green leaves of a houseplant by the window. The face is not shown. Shot at a 35mm equivalent with shallow depth of field, focused on the ring and knuckles. The mood is calm, restorative and quietly observational, as if the night's data were about to be checked.

Magnesium L-Threonate Lifted Oura Deep and REM Scores in 3 Weeks

A 2024 randomized trial tested a brain-targeted form of magnesium, magnesium L-threonate (Magtein), in 80 adults with sleep complaints. After 21 days at 1 g/day, the MgT group had better Oura deep and REM sleep scores than placebo, along with improved mood, energy and alertness. But the placebo group also got worse, the sleep staging came from a consumer wearable, and the study never compared threonate to glycinate or citrate. Here's what the trial actually shows, what a 1 g dose really delivers in elemental magnesium, and where the caveats lie.
