Love this stuff, really helps with my sleep and stress/ anxiety. I like how it’s a bend of the different types of magnesium so I know I’m getting the right type. And a decent price too!

Wow… really like this product! Results are definitely seen, and quickly too. It’s so easy to take in any drink, with no nasty taste like others I’ve tried. I have mine in a glass of juice each morning and you cant tell. Definitely recommend this - makes you look and “feel” better !
