Vitamin D is a secosteriod hormone essential for calcium absorption and bone mineralization which is positively associated with bone mineral density [BMD]. It is well-established that prolonged and severe vitamin D deficiency leads to rickets in children and osteomalacia in adults.
Taking a multivitamin with vitamin D may help improve bone health. The recommended daily amount of vitamin D is 400 international units (IU) for children up to age 12 months, 600 IU for people ages 1 to 70 years, and 800 IU for people over 70 years.
Vitamin D promotes bone health in these ways: Helps absorb the calcium we get from food. Along with calcium, helps protects older adults from osteoporosis. Promotes healthy functioning of our muscles and immune system. We need strong muscles to help us balance and reduce the risk of falling and breaking bones.
Pay attention to vitamin D. Your body needs vitamin D to absorb calcium. For adults ages 19 to 70, the RDA of vitamin D is 600 international units (IUs) a day. The recommendation increases to 800 IUs a day for adults age 71 and older. Good sources of vitamin D include oily fish, such as salmon, trout, whitefish and tuna.
Vitamin D decreases bone loss and lowers the risk of fracture, especially in older adults. Along with calcium, vitamin D also helps to prevent and treat osteoporosis. Adequate vitamin D is needed for efficient calcium absorption.
This review assessed the efficacy and safety of interventions to increase vitamin D. The authors concluded that vitamin D3 plus calcium supplementation has beneficial effects on bone mineral density, fractures and falls without evidence of harm, although these may be limited to particular subgroups.
Vitamin D is well known for its important roles in maintaining calcium homeostasis and bone mineralization via the regulation of calcium mobilization and renal reabsorption, and the intestinal absorption of both calcium and phosphorus [1]. These functions have been established for many decades.
The importance of vitamin D for bone health and prevention of rickets has been known since the early 1930s. Calcium is actively absorbed from the small intestine in the presence of vitamin D. Calcium and phosphorus form hydroxyapatite crystals to mineralize and strengthen bones. Thus, a diet containing both optimal vitamin D and calcium is ...
Calcium and vitamin D are essential to building strong, dense bones both when you’re young and as you age. The information included here will help you learn all about calcium and vitamin D – the two most important nutrients for bone health.
Vitamin D is necessary for strong, healthy bones and muscles. Without Vitamin D, our bodies can absorb only 10 to 15% of the calcium we consume. Children who lack Vitamin D develop a condition called rickets, which causes bone weakness, bowed legs, and other skeletal deformities.
