Eggshell Calcium
Really enjoying this product! I find it difficult to get a high level of calcium in my diet relative to phosphate and this is a super product. Even if you make your own, it is quite difficult to get eggshell to this fine of a consistency.

Bravo!
All of lark's stuff is awesome. It's cool to see them come out with new stuff. This one felt special in the glass jar. The eggs are so finely ground. We really like this stuff in my family. Grateful to utilize these products!
