Comparison
Magnesium L-Threonate vs Omega-3 (DHA/EPA)
Magnesium L-Threonate
MIT-developed magnesium that crosses the blood-brain barrier. Shown to enhance synaptic density and reduce 'brain age'.
Omega-3 (DHA/EPA)
Essential fatty acids critical for brain structure and function. DHA comprises ~40% of brain polyunsaturated fatty acids.

The comparison in plain English
Auto-generated from dataMagnesium L-Threonate and Omega-3 (DHA/EPA) are both in the neuroprotective category respectively. Magnesium L-Threonate MIT-developed magnesium that crosses the blood-brain barrier. Omega-3 (DHA/EPA) Essential fatty acids critical for brain structure and function.
Bottom line
Magnesium L-Threonate (evidence B, safety 5/5) has a stronger evidence base than Omega-3 (DHA/EPA) (evidence A, safety 5/5). 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 Omega-3 (DHA/EPA) if
Omega-3 (DHA/EPA) is the better fit when your goal aligns with its mechanism (DHA (docosahexaenoic acid) is a structural component of neuronal cell membranes, maintaining fluidity and supporting receptor function) and the dose range (1000–3000mg) suits your protocol. Half-life is 24h.
