The two items we have used every day for many years to keep our bodies replenished with minerals are the Red Desert® clay and we always we add Concentrace to all the water we drink (which is distilled water). Add 5 to 10 drops Concentrace minerals to a glass of water. Our usual dosage is one heaping tsp of Concentrace liquid to a gallon of water. This is approximately 75 drops per gallon. You can add these minerals to anything you are drinking. How much to use is a personal decision. Those who have higher mineral deficiencies will want to consider taking in more Concentrace® minerals. Try 10 to 20 drops per day and increase the drops to your tolerance level. If you have constipation, try adding in more drops. If your bowels become too loose, cut back. 8oz – lasts approximately 3 to 6 months – depending on how much you use.
