Naka D3 + K2 Gummies - Vitamins D3 and K2 aid in the absorption of calcium which supports the development and maintenance of bones and teeth. Vitamin D3 is known as the “sunshine” vitamin and is easily synthesized by the body when the sun’s UVB rays strike the skin. It is the most natural form of vitamin D and offers superior absorption. Vitamin K2, or menaquinone-7 is an effective activator of osteocalcin, the protein essential for calcium deposition in bone. It works synergistically with vitamin D3 to help influence mineral strength in bones and teeth.
