Vitamin D is crucial for overall well-being. Made from stone flower (Parmelia perlata), this lichen-based vitamin D3 is free from toxins and other contaminants and is the natural form of D3. Vitamin D promotes mineralization, which is essential in maintaining strong bones and teeth. It also regulates immune system function, promotes ossification of bone, and helps in maintaining blood sugar. It helps the body to absorb calcium and phosphorus, so that bones and teeth become stronger. Vitamin D also strengthens the nervous system and protects the heart.
