Our assessment
The evidence shows that while calcium is essential for bone health, the specific formulation of Nature's Way Stress Defense does not provide enough data for a complete evaluation. Our assessment is based on the calcium content listed in the product. Calcium supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a key structural component for your bones and a signal regulator for your nerves and muscles. It helps your body maintain bone density through mineral deposition and supports muscle relaxation and nerve signaling [NIH ODS]. For you, this means that adequate calcium intake is critical for preventing bone loss as you age.
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high blood levels 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 medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for the specific product "Nature's Way Stress Defense" regarding its complete ingredient list or intended use. For calcium, you should aim to meet your needs through food first. If you take a supplement, be cautious with high doses and monitor for side effects. Always separate calcium supplements from certain medications by at least two hours [NIH ODS].
