If clay were to be used as food, Redmond Clay could certainly meet that classification.
Clay isn't typically defined as food (even though it's used as an additive in some foods). So classifying it as food-grade doesn’t really make sense. But we can say that if clay were to be used as food, Redmond Clay could certainly meet that classification.
We can also tell you that clay has been used internally for thousands of years. And for decades, we've heard from customers who've had amazing experiences using our clay internally, even though we currently only mention the external uses of our clay on the labels and in our marketing.
