What the brand says

Sold as “Zen Supplements - Effervescent Whole Food Magnesium Powder – Mixed Berry 259g”

The pristine sea water and whole food marine red algae (Lithothamnion calcareum) used as a source of magnesium in this formula are collected from the North Atlantic waters near Ireland. Magnesium derived from seawater is in its most natural form and magnesium from red algae which has unique honeycomb cell structure makes it more bioavailable than many other magnesium products. Magnesium is the fourth most abundant mineral in the body that is part of over three hundred biological processes. Most notably it promotes healthy bones and muscles but it is also instrumental in supporting relaxation and can act as a calmative.
