Thanks for those sites, Mari. Thanks mrsD for more explanation.
Sorry I freaked out a little.

Looks worse in the red text though. lol
I was just sitting here thinking to myself about the reasons I was taking it in the first place and then when mrsD mentioned the problems with her skin from the lake water I remembered all the safety signs going up in the lakes where I used to live. Danger signs - do not enter the water type signs. That was because of the algae bloom. Then I was thinking about how it was prescribed to me years ago by a Naturopath and it was years and years ago but I just kept taking it quite blindly without further and newer investigations.
Thankyou all for the information!
bizi, I wish they weren't all so expensive. I guess that's why it's always a good idea for us to double check to make sure we're not taking more than we need and because of that cost we're not paying all that extra money.
