Zeolites are formed where volcanic rocks and ash layers react with alkaline groundwater. They are also known to crystallize in shallow marine basins over a period ranging from thousands to millions of years.
In 2009, James Flowers, et. al.
from North Carolina-based Eno
Research
(www.enoresearch.com),
published the findings of a
study in which volunteers
consumed a suspension of
Clinoptilolite (Zeolite) in water (or a
placebo) for up to 30 days. All
participants were monitored
for clinically significant,
deleterious changes in either
of the urinary and serum
electrolyte panel or the
general metabolic panel. The
Zeolite group experienced a
rapid and significant increase
in the urinary excretion of one
or more heavy metals being
monitored for the study, while
the placebo group was
unchanged.
