When comparing Life Extension Neuro-Mag to standard magnesium citrate or oxide, the primary difference lies in bioavailability and target area. While citrate is often preferred for digestive regularity, L-threonate is significantly more effective at reaching brain tissues. This makes it a superior choice for those who want the cognitive benefits of magnesium without the potential laxative effects associated with lower-quality, high-dose alternatives.
