Our assessment
The evidence shows that calcium is essential for your bone health, but the specific form in Geri-Care Oyster Shell Calcium 500 mg requires careful consideration. Our assessment: this supplement provides a standard 500 mg dose of calcium from oyster shell, which is a common source, but you need to be aware of important safety considerations and potential medication interactions [NIH ODS].
How it works
Think of calcium as the 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]. This means it helps your muscles relax and your nerves send messages properly.
Safety profile
FDA received 592,059 total adverse event reports for products like this. Side effects from high calcium levels can include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms [FDA data]. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. You should also know that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by evaluating your total daily calcium intake from food and other supplements. If you take this product, take it separately from any medications listed above by at least two hours. Data not available for specific dosing guidance beyond the 500 mg per tablet. Discuss with your doctor before starting, especially if you have kidney concerns or take other medications [NIH ODS].
