I have been involved with these trace minerals for over 20 years in all aspects from extraction, processing, shipping and usage on my own horses and animals. And for me and my wives own consumption. A better absorption of nutrients has improved my endurance and well being. My horses’ coats are shiny and hooves strong. It has been shown that vitamins are better absolved in the presence of minerals, thus I feel I am healthier and happier when I use these wonderful trace minerals.
