Yes, it’s reccommended you take about a tablespoon per day of Diatomaceous Earth. I’m doing a teaspoon in the A.M. as it gives me too much energy! Basically it’s minerals, which we all need more of. Food Grade, of course. There are alot of other uses so type in “benefits for human use” and you will get web sites such as: http://www.earthworkshealth.com/human-use.php & wolfcreekranch1.tripod.com/diatomaceous_human_use.html. I personally am hooked and it helped tremendously with caffeine and sugar withdrawls.
