Two forms of Vitamin D are important to humans: Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol). Vitamin D2 is made by plants, whereas Vitamin D3 is made by the human body whenever the skin is exposed to ultraviolet B (UVB) rays from the sun. As little as 10 minutes of sun exposure is thought to produce enough Vitamin D to prevent a deficiency.*
Vitamin D aids in the absorption of calcium and phosphorous, which ensures sufficient blood levels of these minerals for proper calcification of bones and cartilaginous tissues. Sufficient Vitamin D supports bone strength by increasing bone mineral density, and thereby decreases the risk of bone fractures.
Maintaining Vitamin D levels is crucial for preventing deficiency symptoms, which can cause skeletal deformities in children and weak muscles and bones in adults.
Vitamin D is sometimes regarded as a hormone because of its involvement in regulating certain organ and tissue systems.*
Dr. Hulda Clark recommended Vitamin D3to help remove tricalcium phosphate deposits by “mobilizing” the calcium in them.
