Buying Guide
Bioavailability and Brain Absorption
The key advantage of magnesium L-threonate is its ability to cross the blood-brain barrier efficiently. Life Extension Neuro-Mag uses Magtein, a patented form with clinical backing for raising brain magnesium levels. Nootropics Depot Magtein also uses the same patented ingredient, so bioavailability is comparable. However, the delivery system and additional ingredients can influence absorption speed.
Potency and Dosage Flexibility
Life Extension offers multiple capsule counts: 90-count packs (two bottles), 150-count packs, and single 150-capsule bottles. Each serving provides 2000 mg of Magtein (containing 144 mg of elemental magnesium). Nootropics Depot Magtein typically comes in 90-capsule bottles with similar dosing. For those who want to tailor their intake, the larger bottles reduce reorder frequency.
Brand Reputation and Quality Standards
Life Extension has over four decades of experience and provides Certificates of Analysis for all products. Their Neuro-Mag line is non-GMO and manufactured in the USA.
