Most people use some sort of nutritional supplement for healthy living. If your diet is vegan, or vegetarian then you should already know that you do not get everything your body needs without meat consumption unless you use food supplements. Sometimes, it might be a wiser choice to consume foods you might not enjoy rather than looking to supplements for help, if you have a choice. Or divide your intake between supplements and actual food rather than relying fully on any given supplement. One such supplement with potential dangers is calcium.
Osteoporosis is a bone disease affecting mostly people over 35, especially women, characterized by low bone mass and deterioration of bone tissue. In short, it makes your bones more fragile and prone to breaking. Statistically osteoporosis fractures are more common than breast cancer, heart attacks and strokes combined.
The main nutritional supplement used to combat osteoporosis is calcium. Today, calcium supplements are among the most popular supplements used in nutrition. Advertisements claim that these calcium supplements strengthen bones and teeth and prevent osteoporosis. The problem is, actual scientific evidence of such claims has been weak, and with new research, it is becoming even weaker.
An article found in a six year old issue of American Journal of Clinical Nutrition references the 2007 study which found that calcium supplements do not actually reduce fracture rates and may even increase them! Another study which was published in the British Medical Journal issue in 2012 found that using calcium supplements may increase risk of heart attack nearly 2.5 times.
You might not even need to supplement calcium. Many of the most commonly consumed foods in North America are already supplemented and by taking additional calcium supplement you might be taking far more than your body needs.
To be certain of the effects on your particular health and metabolism you should always consult with a medical professional.
