Does taking calcium supplements reduce the risk of osteoporosis or fracture?

 

Sounds logical: If my bones are weak, taking calcium supplements will help strengthen my bones?

With calcium playing such a fundamental role in the makeup of bone it seems reasonable to assume that a disorder of demineralisation might be helped by increasing  calcium through supplementation. 

What has the medical research shown us about the effect of calcium supplementation?

Here are some quotes from research articles
.
“Our analyses indicate that dietary calcium intake is not associated with risk of fracture, and there is no evidence currently that increasing dietary calcium intake prevents fractures. (see reference: 0)
Calcium supplements have very little role to play in the prevention or treatment of osteoporosis.”
There seems to be little need for calcium supplements except in individuals with major malabsorption problems or substantial abnormalities of calcium metabolism 
(see references 1,2,3)

1. Calcium supplementation may increase the risk of fracture!
Here are some quotes from research articles

(5). Warensjo et al  “The highest quintile of calcium intake did not further reduce the risk of fractures of any type, or of osteoporosis, but was associated with a higher rate of hip fracture”
 (6).Sahni, “there is no evidence currently that increasing dietary calcium intake prevents fractures. Calcium supplements have small inconsistent benefits on fracture reduction but probably have an unfavourable risk:benefit profile.”

2. Calcium supplementation may increase the risk of cardiovascular disease!
The following studies show that increasing calcium in our diets by food or supplements may cause artery problems.

(3). Michaelsson,  (2013). Long term calcium intake and rates of all cause and cardiovascular mortality: infarction and cardiovascular events:

3. Calcium supplementation may increase risk of Dementia?
A recent study by Kern et al  published in the journal Neurology, found that elderly women who had already experienced stroke were at higher risk of developing dementia than those who avoid calcium supplementation.

(9). Kern, (2016). Calcium supplementation may increase the risk of developing dementia in elderly women with cerebrovascular disease.

Take home message is there seems to be little need for calcium supplements except in individuals with major malabsorption problems or substantial abnormalities of calcium metabolism

* if you have been advised by your Doctor to take Calcium supplements please continue to do so.
