Alaria has a significant amount of trace minerals. Two capsules will give you your RDA of organic iodine as well as smaller but significant amounts of most vitamins and minerals. It has the most significant amounts of calcium, magnesium and B-vitamins of any edible seaweed. Being a whole food ground into a powder it has all the co-factors, phyto-nutrients, etc. you would expect to find in a “superfood” without the downside of the algae, grass juices, alfalfa, etc. which are common allergens. Studies have also shown it to act as an immune stimulant and binder/detoxifier for heavy metals in the GI tract.
