Why isn’t Shine vegan friendly?

The main ingredient in Shine is micro-crystalling hydroxyapatite, which is derived from the bones of cattle raised on pasture in New Zealand.

We have found a mined source of apatite (which would be vegan), but the cost was astronomical and made it prohibitive to use in Shine.  We are working to find a way to make a vegan version of Shine that would be as effective as our current formula.
