Vitamin D, also known as calciferol, comprises a group of fat-soluble seco-sterols. The two major forms are vitamin D 2 and vitamin D 3.
27 Ιουν 2024 · Vitamin D enhances intestinal absorption of calcium and phosphate. Low concentrations of vitamin D are associated with impaired calcium absorption, a negative calcium balance, and a compensatory rise in parathyroid hormone (PTH), which results in excessive bone resorption.
12 Ιουν 2023 · Calcium and vitamin D are important for keeping bones strong and helping to prevent osteoporosis. Osteoporosis is a common bone disorder that causes a progressive loss in bone density and mass. As a result, bones become thin, weakened, and easily fractured.

CALCIUM ABSORPTION. The classic effect of vitamin D is to facilitate the intestinal absorption of calcium by mediating active calcium transport across the intestinal mucosa. Vitamin D acts in this system by both genomic and nongenomic mechanisms (1, 2).
Vitamin D promotes calcium absorption in the gut and maintains adequate serum calcium and phosphate concentrations to enable normal bone mineralization and to prevent hypocalcemic tetany (involuntary contraction of muscles, leading to cramps and spasms).
18 Οκτ 2016 · Vitamin D is the principal factor that maintains calcium homeostasis. Increasing evidence indicates that the reason for disturbed calcium balance with age is inadequate vitamin D levels in the elderly.
