The influence of the hormonal form of vitamin D on calcium and phosphorus utilisation has a significant impact on bone health. Vitamin D stimulates the absorption of calcium in the intestines which facilitates the calcification of skeletal tissue. It is estimated that a large number of the general population is vitamin D deficient including those living in sunnier climates.
Vitamin K activates the protein, osteocalcin, which is essential for bone formation. Without adequate vitamin K, osteocalcin remains inactive thus leading to defective bone mineralisation and an increased risk of osteoporosis.
