My advice, look up NBPure or just Mago7 on amazon...read the reviews...just would not buy on there. Most vitamin companies carry it. Here is their phone number. 1 800 798 0707. I don't know even if they allow this. So just look at it on Amazon, Mag07...there is not any other. Now by NBPure. Same formula exactly.They like everyone else most likely had to join forces.....do not know how I can post photo on here...good luck, it does work very well...find ur dosage and follow directions. Stay on that maintenance dose. Look up dosing instructions on the net...plenty of info.
Very good product...absolutely no cramping ...and you sleep well!!!!
