There has been some controversey over the chlorella thing ...

1# It has been shown that chlorella may contain mercury especially if it is grown in unsafe environments; notice the word unsafe

2# BUT ... many people also belived that the chlorella held onto the mercury once absorbed and didnt release into the body (but I dont know if this is proven or not; I think it was just conjecture). But imo so is Hal Huggin's conjecture about not using chlorella.

Basically it comes down to alot of different experts out there with almost all of them without the ability to fully test out the specifics or how certain things behave; and thus making conjectures on how to practice.

I'm no expert just a aware consumer.

I'm sure Russ will say not to worry about algin
