What are your thoughts of drying and grinding eggshells to add a smoothie for extra calcium?

The type of calcium in eggshells is not the best for our bodies. It's really good for the plant that can absorb these elemental types of calcium that go into the plant that converts it. The plant uses with the help of bacteria uses like minerals and metals and things like that. And so it starts to convert it but our bodies do better with types of minerals that are connected to a protein either plant based or even an animal. I would get your calcium probably from some dairy or vegetables. I wouldn't grind the eggshells up. You might absorb some but it's not the best.
