Default Best Calcium supplement form?

Right now I am taking a calcium capsule that is liquid filled. I was wondering what other people are taking? I once saw a news story on calcium supplements and they advised to stay away from the solid forms since they were more difficult to absorb. They even showed an x-ray of a person's stomach with the undissolved tablets just hanging out, still undigested. Yuck!

Post Coral Calcium IS calcium carbonate.

From February 2003 edition of the Berkeley Wellness Letter ..

How to Sell a 5¢ Supplement for $1

Debunking the wild claims made for supplements is an ongoing battle. The latest cure-all is coral calcium, promoted widely in health-food stores and on the Internet. It’s probably the most expensive calcium pill in history.

Its manufacturers say that coral calcium not only is the best kind of calcium, but also relieves pain and treats some 200 diseases, including Alzheimer’s, diabetes, and lupus. Some infomercials and websites even boldly announce that coral calcium treats or cures cancer. Moreover, they claim that people on the Japanese island of Okinawa have long and healthy lives because their drinking water contains large amounts of coral calcium, which makes the water alkaline and balances the body’s acidity. Thus, you’re supposed to take more coral calcium if your body is especially acidic. However, if your body were as acidic as some of the labels suggest, you wouldn’t survive long enough to swallow the supplement.

Coral and the shells of sea creatures are made of calcium carbonate, the most common and usually cheapest form of calcium supplement (used in Tums, for instance). Coral calcium also supplies other minerals such as magnesium, mostly in small amounts, which you can easily get from foods or a basic multi-vitamin/mineral pill.

There has been little or no good research on coral as a source of calcium or as a treatment for disease. But that doesn’t stop the marketers from making their claims, since dietary supplements are virtually unregulated. You have no idea what’s really in the bottle or if the stuff is safe. Historically, calcium supplements haven’t always been safe: years ago calcium carbonate from bone meal or oyster shells, for instance, was used in some supplements—but was later found to contain high levels of lead. Since then the government and manufacturers took action to reduce lead levels in existing calcium supplements. But new supplements can go untested.

There are, however, plenty of reliable calcium pills. Generic calcium carbonate pills can cost as little as five cents a day, compared to as much as a dollar a day for coral calcium. There’s no reason to think coral calcium is anything magical, let alone better than other calcium sources, or worth the extra expense.

There has been a lot of debate in the last decade over which is the best form of calcium supplement. A study done in 1999 seemed to indicate that calcium citrate was the hands-down winner, with as much as 27% greater bioavailability than pharmeceutical grade calcium carbonate, which is the more common and least expensive form.

However, a more recent study (2001) showed there was absolutely no difference .. both forms resulted in similarly elevated blood levels of calcium. The difference between the two studies was the length of time between ingestion of the supplement and when the measurements were taken. In the first study, blood and urine were tested 6 hrs after ingestion. In the second study, the tests were done 24 hrs later. So it seems the difference is that calcium carbonate is absorbed more slowly, but ultimately to the same level as calcium citrate.

Also worth noting, in the second study, the participants also took a vitamin D supplement, so it would be wise to ensure that you have 400 units (or mg) per day of vitamin D. Or .... you need to ensure that you get 1 hr of sunshine daily, unfiltered by sunblock or sunscreen.

A little more info ... calcium carbonate does require an acid environment for absorption, therefore it's best taken with a meal, since that is when the stomach secretes acid for digestion. Calcium citrate is absorbed in an alkaline environment, so best taken on an empty stomach.

Bottom line: which form of calcium is best depends on your supplement-taking habits (ie, with meals or between meals) and your wallet. They will all ultimately do the job. Except calcium carbonate from oyster shells, which tends to not even dissolve, let alone get absorbed. And calcium from bone meal may contain dangerous amounts of lead.

Thanks, Doreen, for the helpful information! I currently take a chewable tablet containing calcium citrate, and never knew I should take it on an empty stomach! Very good to know this. I am noticing a difference on the way I feel since taking this form of calcium, but the tablet also contains magnesium oxide, a form of magnesium I've never taken before, so that might be the reason I am feeling better (fibromyalgia). They also contain vit. D. Glad to know I don't need to spend big bucks for the coral calcium!

Thanks Doreen for your very informative reply. I'll have to do a little more investigation to decide which supplement I'll use, if I change it at all.

Update on Coral Calcium ...

(from the News and Public Affairs Unit, Alabama Cooperative Extension System)

Quote:
Beware of Coral-Calcium Claims

Auburn, June 26, 2003 -- There are all sorts of healthy ways to include calcium in your diet, but taking coral-calcium supplements isn’t one of them, according to one expert.

Some manufacturers of coral-calcium supplements claim these products, which are allegedly made from coral derived from ocean waters bordering the Orient, possess special, even remarkable, qualities. Taking them, they say, will help you lose weight, reduce blood pressure and, among other things, even cure colon cancer.

“This is presented as some kind of magical substance, when it actually isn’t,” said Dr. Robert Keith, an Alabama Cooperative Extension System nutritionist and Auburn University professor of nutrition and foods. “What you’re getting is a form of calcium carbonate, which is the same thing you get from a lot of calcium products, such as common anti-acid tablets”

Like many of the false claims associated with dietary supplements, the hype surrounding coral calcium is partly grounded in truth.

“We know, for example, that calcium -- no matter where you get it -- is associated with certain good things,” Keith said. “We know that it promotes healthy bones and aids in the prevention of osteoporosis, a crippling bone disease that occurs mostly among women late in life.”

It is also true that calcium can help reduce blood pressure levels among calcium-sensitive people, a relatively small segment of the population, Keith said. Some studies also have shown calcium may play a role in preventing colon cancer, he added.

Still, as Keith stressed, what we know about calcium and its benefits bears little resemblance to the claims of many coral-calcium manufacturers.

“People are looking at it as a way to lose weight, lower blood pressure or cure cancer,” Keith said.

“Granted, you need calcium. It serves important functions within the body. If may help reduce blood pressure among some people. It may even be involved in the prevention of colon cancer. But in the vast majority of cases, it’s not going to make an obese person thin, a hypertensive person develop low normal blood pressure. And it’s definitely not going to cure colon cancer.”

“What these supplement manufacturers are doing is taking the positive effects associated with calcium and stretching them to make outlandish claims,” he added.

And besides, Keith said, no matter how you manufacture or package it, calcium is still calcium. Just because it may have been mined deep below the sea near the islands of Japan doesn’t make it any more exotic or effective than the calcium commonly found in the 50-cent anti-acids bought over supermarket counters.

Even the magnesium commonly found in coral calcium products can be easily derived from other products, such as one-a-day vitamin/mineral supplements.

If that isn’t reason enough to avoid these products, there is one other problem associated with taking coral-calcium supplements – one that may even carry grave health risks, Keith said. That’s because in addition to calcium, many of these products may contain lead, mercury and other potentially harmful substances.

“Coral calcium, after all, is derived from organisms at the bottom of the ocean that collect a lot of chemicals,” Keith said. “Yes, you get calcium, but you may also be getting lots of other substances, including unacceptable levels of lead.”

As it turns out, the gig may soon be up for some coral-calcium supplement manufacturers.

Recently, the Federal Trade Commission has been monitoring Web sites making these false claims and has not liked what it has seen. In fact, WebMD reported recently that one supplement manufacturer, Coral Calcium Supreme, already has been charged with making false claims about the benefits of coral calcium.
