This is one of those things you have to take on faith; I cannot see into my body on a cellular level and witness the magic and miracle of ELMNT products, but that being said, I think it works. I have only taken about half the tub so far. I got this tub for free plus shipping ($4.99 I think) via a QR code out of another tub of the magnesium "help you sleep capsules", which I have taken for about half a year with mixed but positive results. I feel, but who really knows, am I right? The placebo effect might just be in full force, but if it works either by the power of the powder or the power of my mind, who cares if the result is the same?
Wish I could know what works and what doesn't.
