Subject: Can Vitamin D-3 Do More For Bone Health Than Calcium?
Loss of density and mass in bones has become very common these days because of the increase in the number of people suffering from osteoporosis. It is shocking to note that the number of osteoporosis related fractures in US is more than 1.3 million. Bone health can be improved by taking the right nutrients and minerals. It is generally assumed that calcium is the only mineral needed to prevent and treat osteoporosis. Calcium supplement have been used by many people to improve their bone strength. is it correct?
Do calcium supplements treat osteoporosis completely? The answer is NO.
A recent study conducted in Iceland concludes that maintaining right levels of vitamin D-3 provides greater protection to bones than taking calcium supplements every day.
What are the results of this study?
Maintaining ideal levels of PTH or parathyroid hormone is essential for bone health. It has been proved by researchers that sufficient vitamin D-3 levels ensure the ideal level of PTH and not calcium. PTH is not in the ideal level in an individual who takes more than 1200 mg calcium a day if he has vitamin D deficiency. On the other hand PTH level is ideal in a person who has sufficient vitamin D even if he takes less than 800 mg of calcium a day.
Vitamin D-3 has calcium sparing effect and if the status of vitamin D in the body is assured, there is no need to take calcium of more than 800 mg a day. The results of this study clearly indicate the importance of vitamin D-3 for bone health. It is clear that sufficient levels of vitamin D-3 are more important than sufficient levels of calcium to prevent osteoporosis. In another study, women who were hospitalized for osteoporosis related fractures were studied. It was found that more than 50% of them had vitamin D-3 deficiency.
The duration of the study was two years and it proved that vitamin D-3 supplementation improved the bone strength and reduced the risk of fractures in these women. It is an unarguable fact that calcium is an important mineral to build bones and to keep bones healthy and strong, but how does the human body absorb calcium? It is the presence of vitamin D-3 that helps in absorption of calcium. Without adequate vitamin D-3, intake of calcium supplements is meaningless.
To absorb calcium sufficient amount of vitamin D-3 must be present in the body. Vitamin D-3 is also needed for the efficient utilization of calcium by the body. The mass and density of the bones are increased only when calcium is absorbed by the body. Absorption of calcium is not possible without vitamin D. Vitamin D-3 plays an important role to build bones in children and to keep bones strong and healthy in adults. It also improves immunity, prevents muscle weakness, regularizes the functioning of thyroid glands and helps in blood clotting.
Deficiency in vitamin D-3 may increase the risks of Alzheimer's disease and rheumatoid arthritis. Vitamin D-3 is the natural form of vitamin D. It is produced when skin is exposed to the ultraviolet rays in the sun. Those who live in latitudes, who have dark skin, who spend most of the day indoors and who wear sunscreen lotion whenever they step outdoors lack sufficient levels of vitamin D-3. They should take vitamin-D supplements to avoid a lot of health risks and to improve their bone health.
