Our assessment
The evidence shows that the Life Extension Two-Per-Day Capsules contain Calcium, a mineral essential for bone health. Our assessment: this product provides a significant dose of a well-studied nutrient, but you need to be aware of the specific risks and interactions associated with calcium supplementation. The data does not provide exact amounts per serving for this specific product, so you should always check the label for precise dosing.
How it works
Think of calcium as a structural building block for your skeleton. It works through bone mineralization, supporting bone density and mineral deposition. Additionally, it plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all products, though specific reports for this exact supplement are not broken out. The safety data for calcium is critical to understand: some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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]. 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 checking the label on your specific bottle to confirm the exact calcium dosage per two-capsule serving. Because of the potential for serious side effects and medication interactions, we recommend you speak with your doctor or a pharmacist before starting this supplement, especially if you take any prescription medications. Do not exceed the recommended intake on the label without professional guidance [NIH ODS].
