I am a big fan of this Natural Magnesium, because Lifestream extracts it from the clean and uncontaminated sea waters off the Irish coast.
Seawater naturally contains magnesium salts. Lifestream manufactures this magnesium by filtration, blending and heat drying without the need for adding preservatives or chemical products. The result is a highly bio-available and concentrated dose of elemental magnesium.
I use this product mainly with clients who suffer from constipation, because of its osmotic-type action.
