Our assessment
The evidence shows that calcium is a critical mineral for bone health, but the data on supplementation requires careful consideration. Our assessment: While calcium supports bone density and nerve signaling, high intakes from supplements carry potential risks that you need to understand before starting [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and density, and it also plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. Your body tightly regulates calcium levels, so supplementation should be approached with precision.
Safety profile
FDA received 592,059 total adverse event reports across all products in its database. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High blood and urine levels can cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data]. Calcium can also reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for the specific product "Doctor's Best Best Probiotic" — the ingredient data provided is for calcium, not a probiotic. For calcium, our recommendation: Get your intake from food first. If you supplement, keep total daily calcium (diet plus supplement) under 2,000 mg. Take calcium separately from the medications listed above by at least 2 hours [NIH ODS].
