Ok, I’ve done extensive looking up Spirulina, and it remains controversial. I barely started taking it 3 days ago, and I bought it from GNC. In the label it says 1 pill a day but that is only 500 mg. On all of these websites it says anywhere from 2-10 grams, so what is up with this? I take 2 anyways. Can we star this question please because I want a lot of people to answer this question. Are the big government companies trying to keep this superfood down or something to protect their investments in drugs and vitamins? What is THEE truth about Spirulina? Thanks.
