Our Primal Puddy has the same intended purpose and function as our OG Puddy, but it utilizes ancestral and animal-based ingredients. The Primal Puddy is extremely unique because the blend of base oils that we use provides an abundant natural source of vitamin K2 and vitamin D3, both of which are necessary to move minerals into the teeth. A few key points about the Primal Puddy * The oil base for this product contains vitamin K2 and d3 from the lanolin, emu oil, and egg yolk oil; which ensure calcium and phosphorus get delivered into the enamel. This unique fat-soluble vitamin delivery system allows delivery of minerals into the teeth * We use a significant amount of the highly bioavailable bovine hydroxyapatite (from grass fed New Zealand cattle).
