Remember not all magnesium supplements are absorbable by humans. Absorption of magnesium oxide and stearate is as low as 0-10% (common in supplements) while glycinate, orotate and L-threonate is closer to 100% and the latter seems particularly able to cross the blood brain barrier.
- clumsysmurf 3y agoIt would be very expensive to meet your RDAs with L-threonate alone, in both absolute and relative cost. Mg glycinate probably does as well, the evidence for / against L-threonate form having any impact in the brain is marginal at best.

- arcticbull 3y agoYeah that makes sense, I think my point was to avoid magnesium oxide and stearate since it’s completely useless - rather than advocating for a specific bioavailable form. I think folks assume the form of magnesium in their multivitamin is useful when overwhelmingly it’s not useful at all.
