Calcium supplements are a simple and effective way to get your daily calcium fix. For some people, however, these supplements may cause side effects such as gas or constipation, according to the US National Institutes of Health.
If simple measures (such as increasing your intake of fluids and high-fibre foods) don't solve the problem, you should try another form of calcium – your options are calcium carbonate, calcium phosphate and calcium citrate. Also, it's important to increase the dose of your supplement gradually – take just 500mg a day for a week, then slowly add more calcium. Don't take more than the recommended amount without your doctor's approval.
