Calcium with Vitamin D – Best Nutritional Supplements for Bone Health
December 3, 2010 Most Americans consume various nutritional supplements to support their health and according to a new survey conducted by the Institute of Medicine, most of them consume an adequate quantity of calcium and vitamin D to support their bone health. The study lead to new recommended intake levels of the nutritional supplements and most of these levels depend on the age.
There have been various studies made over the last decade which have tried to find the benefits that calcium with vitamin D could have in various aspects of health, including cardiovascular disease and cancer prevention or immune function and dysfunction.
The IOM committee made various studies but the evidence they found was not enough to prove that these nutritional supplements have an important role in other extraskeletal health effects. Therefore, the study’s authors determined the intake levels which are needed for the maintenance of bone health. Children with ages between one and three need 500 mg of calcium each day, while those between four and eight nee 800 mg of calcium a day. Teenagers need 1,300 mg of calcium a day. The quantity is larger as adolescents experience growth spurts and enhanced bone growth and need much more support. When it comes to adults up to the age of 70, the quantity of calcium falls back to 800 mg a day. The report showed women between 50 and 70 are an exception as they should receive 1000 mg calcium a day.
Determining the right quantity of vitamin D was a more complex process as this supplement is not extracted only from a proper diet. Sunlight is a great resource of vitamin D as well. The IOM committee established that most people need 400 IU of vitamin D a day. The only difference is for people who are 71 or older as they might need up to 800 IU a day.
The study found these dietary supplements are very popular among Americans and Canadians but that there are also people who consume more than they should, by the concept “more is better.” According to the study, the upper level of intake for vitamin D is 4,000 IU a day and for calcium ranges from 2,000 mg to 3,000 mg per day. Still, the authors said the high-level of calcium can lead to an increased risk for kidney stones or cardiovascular disease.
