Our assessment
The evidence shows that calcium is a crucial mineral for bone health, but you need to be careful with dosing. Our assessment is that you should not exceed the recommended daily intake without medical supervision, as high levels carry significant risks [NIH ODS].
How it works
Think of calcium as a structural builder for your bones and a signal regulator for your nerves. It supports bone density and mineral deposition while also helping your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels in your 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 getting calcium from food sources first. If you need a supplement, take it with meals and separate it from medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin, as calcium can reduce their absorption [NIH ODS]. Do not exceed 2,000 mg per day from all sources without your doctor's approval. Data not available for specific dosing for the BulkSupplements.com Vitamin B12 (Methylcobalamin) product listed.
