Life Extension Neuro-Mag L-Threonate compared with Thorne Magnesium CitraMate + D-5000 on dose, price, reviews, and clinical fit.
L-threonate (brain-crossing) vs citrate-malate (general daily). Two practitioner-tier magnesiums for two different goals. Neuro-Mag L-Threonate is brain-crossing magnesium.
