Geri-Care Calcium 600 + D 5 mcg

Our assessment

The evidence shows that this product provides a standard dose of calcium and vitamin D for bone support. The data confirms that calcium supports bone density and mineral deposition, while vitamin D aids in calcium absorption [NIH ODS]. This combination is widely recommended for maintaining skeletal health, but you should be aware of specific safety considerations before adding it to your routine.

How it works

Think of calcium as the building block for your bones and teeth, and vitamin D as the key that helps your body use that calcium effectively. Calcium supports neuromuscular relaxation and nerve signaling, while vitamin D helps regulate calcium levels in your blood [NIH ODS]. Together, they work to maintain strong bones and proper muscle function.

Safety profile

FDA received 592,059 total adverse event reports across all products. 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Start with a single tablet daily, providing 600 mg of calcium and 5 mcg (200 IU) of vitamin D. Take it with food for best absorption. If you take thyroid medication, antibiotics, or osteoporosis drugs, separate your calcium dose by at least 2 hours to avoid absorption problems [NIH ODS]. Do not exceed the recommended dose. If you have a history of kidney stones or heart disease, consult your healthcare provider before starting. Data not available on specific side effect report counts for this exact product.
