Life Extension Two-Per-Day Tablets
Brand: Life Extension · Form: TABLET [E0155]
Our assessment
The evidence shows that Life Extension Two-Per-Day Tablets provide calcium, a mineral essential for bone health. However, the data indicates that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. You should carefully evaluate your total calcium intake from food and supplements before adding this product.
How it works
Calcium acts as a master regulator for your body. It supports bone mineralization by helping deposit minerals into bone tissue, and it promotes neuromuscular relaxation by supporting muscle relaxation and nerve signaling [NIH ODS]. Think of it as the structural foundation for your skeleton and a key player in how your nerves and muscles communicate.
Safety profile
Data not available for specific product reports. The FDA received a total of 592,059 adverse event reports across all products [FDA data]. 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
Before taking this supplement, you should calculate your daily calcium intake from food sources. If your diet already provides adequate calcium, adding more from supplements could pose risks. Always take calcium supplements with food and separate them from the medications listed above by at least two hours [NIH ODS].
