  1. There is no strong evidence that calcium supplements increase bone health and strengthens the teeth and the new researches in the recent past proves this.
  2. A recent analysis in 2012 claims that intaking a higher amount of calcium more than recommended diet guidelines, provides no benefit in lumbar vertebral bone and hip in older adults.

Another BMJ published meta-analysis study of 12000 people found these risks:

  • Calcium supplements increase Heart attack by 31%.
  • Calcium supplements increase the risk of stroke by 20%
  • Calcium supplements increase the risk of Death by 9% (By all causes)

An analysis involving 12,000 men published in JAMA Internal Medicine found that intakes of over 1,000 mg of supplemental calcium increase the risk of cardiovascular diseases heart attack and calcification of arteries by 20%. This claim was made by a JAMA Internal Medicine study involving 12000 people.

Many researchers suspect, the main reason for the calcification of arteries is the increased amount of calcium in the blood due to the intake of a large amount of calcium through calcium supplements. This is not the case with calcium obtained by the intake of food that is rich with calcium because of slower absorption and small in quantity compared to supplements. The calcium from food digest easily and get absorbed by the body fully.

The researchers are also suspect that the extra amount of calcium intake which is more than one’s daily required amount is unnecessary and the bones don’t absorb them. The extra amount of calcium is sent to the kidneys and this increases the risk of kidney stones.

Another study of risks with extra calcium in the blood found that it increases the risk of prostate cancer and also increases the risk of kidney diseases like kidney stones.

Lab analysis by a consumer lab found that calcium supplements of many brands failed quality tests for lead contamination and the brands have mislabeled contents.
