Our assessment
The evidence shows that calcium is a well-supported mineral for bone health, but the specific combination in Schiff Calcium Plus Magnesium must be considered carefully. Our assessment is that this supplement can be useful if you need to increase your calcium intake, but you should be aware of the potential risks and interactions before starting [NIH ODS].
How it works
Calcium works as a key structural component for your bones. It supports bone density and mineral deposition, which is critical for maintaining strong bones as you age. Additionally, calcium plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes might 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 [NIH ODS] [FDA data].
Our recommendation
Start by assessing your current calcium intake from food. If you need a supplement, take it with food and separate it from medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin by at least two hours [NIH ODS]. Do not exceed the recommended dose on the label without consulting your doctor.
