Almost  all recommendations are for 1 tablespoon per day, not  2.

This,- on the post from Garnet who spoke personally to Dr. Knight---  Dr. 
Knight recommends  " A teaspoon a day for two years is better  than a cup a 
day for two months.

I just talked to Dr Galen Knight who conducted the original research  on
DE as a metal detox. He also did the lab analysis that appears on  Earth
Works Health site.

His opinion is that the Silica from DE is not  absorbed, does not show up
in hair analysis and that the health claims made  as to it being a good
source of Si are not valid.

He is very into  toxic metals. Here is an excellent article that explains
a great deal about  DE as a metal detox agent. And sources of metals
contamination.

IF  any silica is absorbed from DE it is very, very little and it would not
be  likely to be in a bioavailable form since silicon dioxide is a very
stable  form of silicon, essentially it is sand. So chances are that

Better to  increase dietary sources as mentioned in my previous post.
Si is in onions,  leafy greens, herbs like horse tail, oat straw and nettles
are particularly  high in Si.

I enjoyed talking to Dr Knight about some of his other  research into an
immune factor Vitalethiene that he discovered as a grad  student. He has
continued his investigations into the importance of this  substance in 
cancer
and other degenerative conditions and how it is impacted  by metal toxicity.
Hence his interest in DE as a metal detoxing agent. He  does caution users
of DE to go slow and plan on taking it for a long time  rather than using 
a lot
of DE to detox quickly due to the risk of drawing  large amounts of metals
into the circulation and reexposing your organs and  tissues. A teaspoon a
day for two years is better than a cup a day for two  months.
