Calcium Citrate With Vitamin D

Calcium citrate with vitamin D supplements can be found in most supermarket and drug stores. calcium-citrate-with-vitamin_d | Article Calcium citrate is the calcium salt of citric acid.  It is produced by having citric acid neutralized by calcium hydroxide.

Based on recent  bone health scientific findings, most calcium supplements are now fortified with vitamin D.  Calcium citrate with vitamin D is no exception.  Fortunately, vitamin D is not expensive, so the cost of calcium supplements is largely unchanged by this addition.

What are the pros and cons of calcium citrate with vitamin D?  According to Harvard Health Publications (http://www.health.harvard.edu/newsweek/What_you_need_to_know_about_calcium.htm):

“People are usually advised to take calcium carbonate with or soon after a meal. Calcium citrate can be taken at any time.  Calcium carbonate may cause acid rebound: the stomach overcompensates for the high dose of calcium carbonate, which is alkaline, by churning out more acid.  For that reason, people with a history of stomach ulcers are advised that they may not tolerate it and may have to switch to calcium citrate.”   

CalcumInfo.com noted the following:

"Both calcium carbonate and calcium citrate can be taken with acid-reducing agents such as antacids, H2 antagonists or prescription medications, such as Prilosec™. And both calcium carbonate and calcium citrate are appropriate for people with normal gastric pH, achlorhydria, hypochlorhydria, heartburn, and GERD.[Calcium carbonate is more concentrated than calcium citrate supplements] and has about twice as much elemental calcium by weight as calcium citrate. Therefore, it requires fewer or smaller tablets to achieve a given dose of elemental calcium, the calcium your body actually uses.

A recent study in the Journal of the American College of Nutrition compared the absorption and cost-effectiveness of single doses (500 mg) of commercially-available Os-Cal® calcium carbonate and Citracal® calcium citrate in 24 postmenopausal women.  The researchers, led by Dr. Robert P. Heaney, found that both calcium supplements were absorbed equally…However, Citracal costs between 1.5 and 1.8 times as much as Os-Cal® per mg of elemental calcium. Factoring in the savings in annual health care costs that could result from preventing fractures...cost benefit analysis of the two supplements documented that treating all people 65 years or older with Os-Cal® could yield net savings of up to $478 million in U.S. annual health care costs. Because of their higher cost, there were no savings if Citracal supplements were used in place of Os-Cal®."  

Heaney et al also noted from his study that calcium citrate with vitamin D reported higher rates of absorption than the same calcium without vitamin D.

Because each pill has less elemental calcium gram for gram, you will need to consume more calcium citrate with vitamin D pills daily to reach your recommended intake of calcium.  Other forms of calcium calcium-citrate-with-vitamin_d | Articleoffer some of the solubility advantages of calcium citrate without the shortcomings   AdvaCAL, with unique AAACa calcium, is highly soluble – like calcium citrate -- but with elemental calcium levels comparable to calcium carbonate. AdvaCAL has also demonstrated consistent increases on bone density..  It is also free of dyes or preservatives. BoneLossAndYou.com provides clinical research and ease of use comparisons among several leading calcium brands, including one containing calcium citrate with vitamin D.
