Brain & Cognitive.

Absorbable forms for calm, focus, and the nervous system.

Two well-studied families sit here: L-theanine for calm focus without sedation, and a highly absorbable magnesium L-threonate. Magnesium contributes to the normal functioning of the nervous system and to normal psychological function. EX1 ships both at considered doses.

Why this category matters

Magnesium L-threonate is a highly soluble form of magnesium chosen for how efficiently it is absorbed. EX1 declares both the salt weight and the elemental magnesium so the dose is transparent.

Magnesium forms differ in how well they are absorbed. L-threonate is chosen for its solubility and absorption profile, so a stated elemental dose is delivered in a well-tolerated form, with both numbers on the label.

Authoritative reviews recognise magnesium's contribution to the normal functioning of the nervous system and to normal psychological function.

How to choose a brain & cognitive supplement

Match the form to the goal
A highly absorbable L-threonate for the nervous system. L-theanine for calm focus without drowsiness. They stack well.
Read the elemental dose for magnesium L-threonate
The magnesium L-threonate protocol is roughly 1.5 to 2 g of L-threonate compound per day, providing approximately 144 to 192 mg elemental magnesium. Lower doses do not produce the studied serum response.
L-theanine is dose-dependent and fast-acting
100 to 200 mg per serving. Effects on calm focus typically appear within 30 to 60 minutes of dosing.
Caffeine pairs
L-theanine is the classic pair with caffeine for jitter-free focus. The combination has consistent trial support.
