Our assessment
The evidence shows that the calcium in Life Extension One-Per-Day Tablets is effective for supporting bone health, but you need to be aware of specific risks and interactions. Our assessment is that this supplement can be a useful part of your routine, provided you monitor your total calcium intake from all sources, including food and other supplements.
How it works
Think of calcium as a structural building block for your skeleton and a signaling molecule for your nerves. It supports bone mineralization and density by helping deposit minerals into your bone matrix. It also promotes neuromuscular relaxation by supporting muscle and nerve signaling [NIH ODS].
Safety profile
Data not available for this specific product; however, FDA has received a total of 592,059 adverse event reports for all dietary supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Very high levels in your 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].
Our recommendation
Start by reviewing your total daily calcium intake from food, water, and other supplements. If you take this tablet, be aware that calcium can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Take the supplement at a different time from these medications. We recommend staying within the safe upper limit for calcium and consulting your healthcare provider before starting, especially if you have a history of kidney stones or heart conditions [NIH ODS].
