Hi Karen,

You're welcome. I typically take 4 algin at night right before I go to bed and I know I don't drink more than half a glass of water, if that. I've never experienced the heart-pounding that you mentioned, and I honestly don't know what would cause this. Hmmmm.

As far as mercury levels in foods and supplements...I thought the following info might be interesting to you.

According to information another NSP distributor gave me, the limit for California's Proposition 65 for mercury in ANY dietary supplement is 0.3 micrograms. This is a very small amount that can only be detected with special equipment (which NSP has).

In fact, according to the World Health Organization's "Environmental Health Criteria" document published in 1991, they estimated that people ingest the following amounts of mercury daily from:

Amalgam fillings - 3 to 17 micrograms per day
Fish/Seafood - 2.3 micrograms per day
All other foods - 0.3 micrograms per day

And as I mentioned before, there's a lot of California produce that doesn't even pass Prop 65, but since people have to eat, these foods are exempted.

So, as far as doing a mercury test on Algin, you'll want to make sure your test kit can measure mercury at least as low as 0.3 micrograms.

Hope this helps!
