Safety of Calcium
There are many precautions and warnings to be aware of concerning the safety of calcium. Although it is a relatively safe substance, you should talk to your healthcare provider before taking calcium supplements if you have sarcoidosis, kidney stones, or kidney disease. Calcium could worsen these conditions; certain medical conditions may also increase calcium absorption (which can lead to problems).
Calcium is a relatively safe substance, especially when taken at reasonable dosages. However, some people may be more likely to experience problems due to calcium. You should talk with your healthcare provider prior to taking calcium if you have:
- Achlorhydria (low or absent stomach acid)
- An overactive parathyroid gland (hyperparathyroidism)
- High phosphate levels in the blood (hyperphosphatemia)
- Low phosphate levels in the blood (hypophosphatemia)
- Kidney disease, such as kidney failure (renal failure)
- Kidney stones
- Any allergies, including allergies to foods, dyes, or preservatives.
Also, let your healthcare provider know if you are:
- Pregnant or thinking of becoming pregnant
You should also be sure to tell your healthcare provider about all other medicines you are taking, including prescription and non-prescription medicines, minerals, and herbal supplements.
