I was merely curious when I ordered this volcanic fulvic mineral powder. It was a good price, good quality, delivered quickly via regular delivery fee. I used only a small amount, it came with a wooden spoon scoop, but I only used the handle with about 1/4 inch on it, maybe 250mg. I mixed with my protein powder, has slight mineral taste, not bitter, not gritty. It seemed to supercharge my digestion tract and burn up all of the food much more efficiently. Provided more energy too. I would recommend for anyone with digestive issues. Seems to make for more complete nutrition. I think that 2 ounces would last many months based on the small dosage that seems to work well.
