Actually, we need more trace minerals than we realize.  Animals too.  75 or 70.  What a petty correction!  Copying and pasting from the website to correct me (we can all read, thank you very much) does not change the fact that this product has changed our lives.  It's almost as silly as copying and pasting the dust warning signs.  Entertaining, but not helpful.  I have since noticed the dust warning labels on all of our feed bags.  It's everywhere.  For us, when it comes to azomite, the proof is in the health of our animals. 
 
Since we've started azomite, I have not had a single health issue nor have had to put a single animal down.  Health issues we did have cleared up immediately and have not returned since.  Our goat that was so very sick and limping is now running and jumping.  Our vet recommended we put her down as she was so bad, now he is also a believer of azomite.  She went from being down crawling on the ground for three months straight to hoppng around in less than 48 hours after being given azomite.  I never expected it.  Our sheep all got pregnant and are successfully lambing with no need for help.  We also no longer have to worm our animals due to overall health just being better.  A weekly herb treatment is all they need for maintenance.  If someone does not want to try it because they don't fully understand the benefits, that's their perogative.  There are lots of products out there. 
 
Our animals that are well-fed fight over eating azomite when I put it out.  Of all the minerals we put out, they eat this one the most.  If someone actually tried it and had no or negative results, that would be a more helpful review.  But our own experience has been really great and I will continue to use it. The few times I have stopped using it because we ran out, our goat starts her limping all over again but it is cleared up as soon as she gets azomite. Our vet has told us to keep using it and has reported other clients also having good results.  He did say that he thought it had to do with overload of certain minerals, binding, etc.  A lot of stuff I didn't understand but that our goat might be more sensitive to that than other animals.  She is a warm climate breed so that might account for it.  Also, everyone else I have recommended it to now also love it and we all buy it regularly.  A few of my friends buy it in bulk to split the cost for their chickens and ducks.  I have a neighbor that now gives it to her Angus cows as her soil analysis is the same as ours. 
 
We found azomite after doing a complete soil analysis of our pastures, azomite was the best fit for our farm as it has the minerals we are lacking in our soil, water and grass. In working with a soil scientist, we found azomite.  When you compare our soil analysis next to the azomite analysis, they balance each other out very well.  It s very unhealthy for animals to get too much of certain minerals and not have others to balance them out.  We had two choices, give it directly to our animals or spread it out over the pastures.  It is more affordable for us to give it directly to the animals than to try to spread it out over many acres. It would require several truckloads to spread it out.  Azomite has been a great experience for us and I am hoping our soil health improves through the animals eating it.  I do add a little bit to our mag/calcium mixture when we spread it out over the pasture in an effort to introduce it slowly at a time.  I'll let you know how the next soil analysis comes out in a year.
 
I do recommend having a soil and water analysis done if you haven't.  You will understand how minerals work in a way you didn't before.  It's a great experience.  Also, you might not benefit from azomite if your soil already has all the minerals it needs.  We live in a wet and rainy climate and generally azomite does well in those areas.
