Natural magnesium from 2,200 feet below Hawaii’s pristine, mineral-rich Kona Sea. Make your own refreshing mineral water with the naturally occurring magnesium, chloride and potassium and trace amounts of calcium, iron, copper, zinc, manganese and sodium chloride in our drops.* Liquid magnesium is a natural wonder with many incredible benefits, including muscle relaxation, restful sleep and mild stress relief.* This highly bioavailable form ensures quick absorption to help support hundreds of biological functions that need magnesium — and overall well-being. We bring up the ocean water via a pipeline and place it in long solar tubes, where it starts forming salt crystals. As the crystals form, there’s water runoff, the source of the magnesium drops. We then scoop off the salt crystals by hand to access the clean mineral drops; a simple, old-school process free of machinery. This precious product takes time and effort to harvest, so you won't find it in stores.*
