The Best there is!

I tried another brand of magnesium powder, and it always left a "dusting" in the bottom of my bottle, but this stuff here DOES NOT! As long as you don't overload or saturate your carbonated water, this will work and you can rest assured it is a quality product. I highly recommend

Awesome product!

I'd never even heard of magnesium bicarbonate until coming across crucial 4 magnesium bicarbonate. I mix with a cold carbonated spring water and let it sit over night. After year of taking various magnesium supplements to no avail, im finally getting the results I was looking for. Please keep this amazing product available, its hard to find and I love that its sourced naturally.
