Thorne Cognitive Vitality

Roughly 75% of adults fall short of the recommended daily magnesium intake, and endurance training adds to that deficit since you lose magnesium through sweat on top of everyday dietary shortfalls. Standard magnesium forms like citrate or oxide are built to correct that in your body generally, but they don't cross into brain tissue especially well.

Thorne Cognitive Vitality is built around Magtein, a patented form of magnesium L-threonate shown to raise magnesium levels in the brain specifically, because it crosses the blood-brain barrier more effectively than other magnesium compounds.

Reaches brain tissue, not just muscle – Magnesium L-threonate is formulated to cross into the brain more effectively than standard forms, supporting the neural processes tied to memory formation and learning.

NSF Certified for Sport – Every batch is tested for compliance with label claims and screened against nearly 300 substances banned by major athletic organizations, a certification not every Thorne cognitive product carries.

Single ingredient, no added blend – Just Magtein magnesium L-threonate and the capsule shell, so you know exactly what you're getting without a proprietary stack to decode.

Magnesium plays a role in hundreds of enzymatic processes throughout the body, but its effect on brain function depends on how much actually reaches neural tissue. Magnesium L-threonate was specifically developed to solve that delivery problem, raising magnesium levels inside the brain in ways that support memory, learning, and the nervous system relaxation that feeds into sleep quality. That relaxation piece matters as much as the memory piece, since your body does a large share of its recovery work while you sleep.

How to Use Thorne Cognitive Vitality

Dose: Take three capsules daily, with or without food.

When to take: Consider taking your dose in the evening, since magnesium's effect on nervous system relaxation feeds directly into the sleep quality where a lot of that day's recovery actually happens.

Consult your healthcare provider before use if pregnant. Gas, bloating, or diarrhea can occur with magnesium supplements in some individuals and typically resolves at a lower dose.
