Functions: Vitamin D is required for the absorption of calcium and
phosphorus from the small intestine, their reabsorption in the kidneys, and
the mineralization process of the bones. It thus supports healthy bone growth.
It also plays an important role in the proper functioning of muscles, nerves,
blood clotting, cell growth and energy utilization.
Deficiency: Vitamin D deficiency causes delayed closure of the
fontanelles in infants and impairs tooth development. In adults a shortage of
vitamin D can lead to softening of the bones and spontaneous fractures. A lack
of vitamin D may also prevent adequate adsorption of calcium and contribute to
osteoporosis. Vitamin D also plays a role in immunoregulation and the healing
of skin disorders. In animal production vitamin D deficiency can cause growth
depression, leg disorders and thin egg shells. Therefore supplementation is
necessary for young animals and high-performance laying hens.
Product forms: DSM vitamin D is available as vitamin D3 in crystalline
form, as an oily solution or as a spray-dried powder for animal nutrition.
