Here’s important information for anyone taking or considering taking calcium supplements for bone health. There’s now research showing that it does not work to protect aging bones.
New Zealand researchers analyzed more than 100 previous studies found no proof was found that boosting calcium intake beyond normal dietary levels strengthens bones or prevents fractures. Their message is very strong. They say guidelines advising seniors to consume at least 1,000 to 1,200 milligrams of calcium a day are misplaced, and that most people on this regimen should stop it.
They argue that while there is no evidence that it helps, too much calcium increases the risk of kidney stones and possibly heart attacks. The study authors acknowledge that it may take a while for doctors and dieticians to adjust to the new evidence, because it goes against the strong messages we have been hearing for years about the importance of calcium.
Some doctors worry that the new message is too extreme, and of course there are cases where calcium supplements are needed. So as always, the bottom line is talk to your doctor.
