Oyster Shell Powder

Oyster Shell Powder (OSP) from Coral LLC is harvested from ancient oyster shell beds located in the Caribbean islands. This is where its white color comes from.

While there are different oyster shell sources, such as the one in San Francisco, not all sources are as pure as Coral LLC’s. Most oyster shell powder products found on the market are inferior quality, as is indicated by its gray color.
