Our assessment
The evidence shows that calcium is a critical mineral for bone health, but the risks of supplementation are often overlooked. For many people, getting calcium from food is safer and more effective than relying on supplements [NIH ODS].
How it works
Think of calcium as the building block for your skeleton. It supports bone mineralization and density, and also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received 592,059 adverse event reports for products in this category. High calcium intakes may increase the risk of heart disease and prostate cancer. High levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [FDA data] [NIH ODS].
Our recommendation
We recommend getting your calcium from dietary sources first. If you must supplement, be cautious with dosing and monitor for side effects. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin — take calcium supplements at a different time of day than these medications [NIH ODS].
