I
use Neways brand but you can buy other brands from health food stores. Colloidial minerals are
in liquid form taken from dead lakes, the plant life absorb the minerals from the ground and then when heavy rain & flooding occur they end up in the lake , making the lake rich in bioavailable (easily absorbed) minerals, herbs etc. Also no heavy metals for your body to get rid of and safe to use when pregnant, for kids and infants.
