Excerpt from United States Senate document #264:
"It is bad news to learn from our leading authorities that 99 percent of the American people are deficient in these minerals, and that a marked deficiency in any one or more of the important minerals actually results in disease. Any upset of the balance, any considerable lack of one or another element, however microscopic the body requirement may be, and we sicken, suffer, shorten our lives."
I take about 50 ml of it every other day and add it to fruit juice or a smoothie. I started out taking it every day. My wife drinks 50 ml of it in a glass of RO water. I buy it for my family's use. Over the years, my dad use to take it. He claims it reversed his arthritis in his shoulders. Other friends have bought colloidal minerals, but I lost track of them many years ago.
On Survival website they list different protocols.
