Life Extension One-Per-Day Tablets
Brand: Life Extension · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that Life Extension One-Per-Day Tablets provide a meaningful dose of calcium, a mineral essential for bone health. However, we need to be careful with the specific intake level, as the data indicates that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone density and mineral deposition through a process called bone mineralization, and it also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
The FDA received a total of 592,059 adverse event reports across all products, but specific report counts for this supplement are not available. The data does list several side effects from high calcium levels, including constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS] [FDA data]. You should also know that calcium can reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Our assessment: You should take this supplement only if you know your dietary calcium intake is low. Be aware that high intakes might increase the risk of heart disease and prostate cancer, so do not exceed the recommended dosage on the label without consulting your doctor [NIH ODS]. If you take any prescription medications, separate them from this supplement by at least two hours to avoid absorption issues [NIH ODS].
