Only one that works

I have tried other brands of this magnesium, but I always come back to Source Naturals, because it's the only one that actually works. Might as well flush your money down the drain if you buy a different brand.; I never felt like they did a thing. This is the real deal.

Excellent

This is one of the best magnesium’s on the market. Magnesium L threonate is the only one that crosses the blood/brain barrier. Excellent product and highly recommended by our doctor.
