Marine algae and seaweeds have been evolving on earth for a much longer time than terrestrial plants, which is why their chemical makeup is so much more advanced. They have evolved to deal with a wide range of harsh environments which has resulted in their extraordinarily high percentages of vitamins, minerals and especially antioxidants. On top of that, their seawater environment contains almost identical chemistry as blood plasma, lymph, and the fluids of the human body. From seawater, seaweed absorbs the same concentration of minerals and essential elements that our bodies need to survive.  All of these adaptations have created bioavailable compounds that protect cells against environmental aggressors such as ultraviolet radiation, pollution, smoking, and deficient nutrition. Certain seaweeds have been proven in clinical trials to be highly effective when applied topically to the skin, which is why all our products include at least one kind of seaweed based ingredient. Our seaweed is sustainably harvested off the coast of Brittany in France.
