Comparison
Magnesium L-Threonate vs CBD (Cannabidiol)
Magnesium L-Threonate
MIT-developed magnesium that crosses the blood-brain barrier. Shown to enhance synaptic density and reduce 'brain age'.
CBD (Cannabidiol)
Non-psychoactive cannabinoid from hemp. Anxiolytic, anti-seizure, anti-inflammatory. The supplement market has grown explosively despite mixed evidence base.

The comparison in plain English
Auto-generated from dataMagnesium L-Threonate and CBD (Cannabidiol) are both in the neuroprotective category respectively. Magnesium L-Threonate MIT-developed magnesium that crosses the blood-brain barrier. CBD (Cannabidiol) Non-psychoactive cannabinoid from hemp.
Bottom line
Magnesium L-Threonate (evidence B, safety 5/5) matches the evidence base of CBD (Cannabidiol) (evidence B, safety 4/5). Magnesium L-Threonate has the slightly cleaner safety profile. For users new to either, the higher-evidence option is the safer first try.
Choose Magnesium L-Threonate if
Magnesium L-Threonate is the better fit when your goal aligns with its mechanism (L-threonate is a sugar-acid carrier that uniquely enables magnesium to cross the blood-brain barrier in meaningful quantities, most oral magnesium forms (oxide, citrate, glycinate) raise serum magnesium but not central magnesium) and the dose range (1000–2000mg) suits your protocol. Half-life is 6h.
Choose CBD (Cannabidiol) if
CBD (Cannabidiol) is the better fit when your goal aligns with its mechanism (Modulates the endocannabinoid system through indirect mechanisms, CBD doesn't bind CB1 or CB2 receptors directly like THC does) and the dose range (25–600mg) suits your protocol. Half-life is –h.
