vitamin D
Bone-building supplement
Vitamin D is a group of fat-soluble vitamins essential for calcium absorption and bone health.
The body produces it when skin is exposed to sunlight, earning it the nickname "the sunshine vitamin." Deficiency causes rickets in children and bone softening in adults.
Found naturally in fatty fish and egg yolks, it's often added to milk and cereals: My doctor said my vitamin D levels were low.
