Calcium Supplements in Kids Overrated?

April 18, 2006 — Most kids who take calcium supplements — or eat calcium-fortified foods — don’t get stronger bones, a review of clinical studies shows.

The audit, by Tania Winzenberg, MD, and colleagues at Australia’s Menzies Investigate Organized, analyzed data from 19 considers of calcium supplements in children aged 3 to 18 years. The analysts selected as it were considers that tried calcium supplements against inert fake treatment and included measurements of bone densitybone density. The time frames of the considers were between 8.5 months and seven a long time.

Pooled data on all 2,859 children in the studies showed that calcium supplements had very little, if any, effect on children’s bone density.

“There is ‘gold’ level prove that calcium supplements may not help to build stronger bones in children sufficient to create a difference within the hazard of breaking a bone,” Winzenberg and colleagues type in. “The results of this review do not back the utilize of calcium supplements in healthy children.”

The findings appear within the current issue of The Cochrane Library. It is published by the Cochrane Collaboration, an universal exertion to assess health care research based on exacting criteria.

The thinks about of calcium supplements included thinks about of calcium pills as well as calcium extricated from drain and added to nourishments.

“We found there wasn’t much effect at all,” Winzenberg told the Wellbeing Behavior News Service. “It does challenge what we thought we knew.”

Kids Require Calcium

Kids’ bone density could be a major figure in how effectively they break bones. But that’s small potatoes compared to the deep rooted consequences of too-low bone density. From the time people enter puberty until the time they are youthful adults, they construct up essentially all the bone they ever will have. Low bone density during late childhood predicts osteoporosisosteoporosis in later life.

Childhood break rates are up — a sign that kids aren’t building solid enough bones. Calcium may be a primary ingredient for bone building, notes calcium and osteoporosis expert Robert Heaney, MD, professor of pharmaceutical at Creighton University in Omaha.

“You have got to have calcium otherwise you can’t store it as bone,” Heaney tells WebMD. “The human body is born with 25 grams of calcium at birth. We have to be compelled to build that up by count calories. The address is how much is enough to do that.”

The Winzenberg investigation found that calcium supplements didn’t have an impact, even in kids who were getting too little calcium in their diets. But only three of the ponders included within the examination included kids getting less than 500 milligrams of calcium a day.

“In case a child is getting up to 600 milligrams to 800 milligrams of calcium a day, giving more will not offer assistance,” Heaney says. “So on the off chance that a child is in that run, I would predict a consider would not find any advancement from calcium supplements.”

Andrew Shao, PhD, is bad habit president for logical and regulatory undertakings at the Council for Responsible Sustenance, a supplement-industry trade gather. He says that though the Winzenberg group did a exhaustive investigation of the clinical data, its conclusions are based on giving calcium supplements for a generally short time.

“One thing that hasn’t been done in clinical trials is looking at long-term calcium supplements over the a long time where peak bone mass is accomplished,” Shao says. “That is the foremost basic piece of evidence lost here.”

Indeed, Winzenberg and colleagues do stressstress the require for long-term studies of calcium supplements in children in their peak bone-building a long time.

Getting Calcium Normally

A major source of calcium is dairy nourishments. In a written explanation, the National Dairy Chamber tells WebMD it isn’t surprised by the think about discoveries.

“Supplements don’t measure up to milk and dairy nourishments when it comes to nourishment,” the NDC says. “In addition to being an amazing source of calcium, milk provides vitamin D, potassium, and magnesium, all of which are basic for ideal bone wellbeing and human improvement.”

Still, a few kids don’t get enough of these basic supplements. Might supplements help? Yes, says Heaney.

“Food sources of calcium ought to be favored overwhelmingly,” he says. “But that’s not to condemn supplements. Well-formulated supplements will permit you to retain as much calcium in milk or in calcium-fortified orange juice.”
