This blue green alae is WILD- the way it was millions of years ago- NOT from a greenhouse protected from the elements and invaders etc. untouched and un-modified by man- this algae must survive in the wild- When I take this I just feel better- after taking it on an empty stomach first thing in the morning I feel like my immune system is stronger and I have clearer thinking - I also think anyone who wants to protect their body from cancer or has cancer should definitly take this. Also I've been taking it for years and get regular comments about how young I look! IHerb is the best place to buy-and price is fair- Thanks!!
