Our assessment
The evidence shows that the active ingredient in this product, calcium, is essential for bone health, but the specific dose and form of this Sundown Naturalist product are not available in the data we have. Our assessment is that while calcium is a well-studied mineral, you should be cautious because high intakes have been linked to serious health risks [NIH ODS].
How it works
Think of calcium as a structural builder and a signal messenger. It is critical for bone mineralization, helping to build and maintain your skeleton. It also supports neuromuscular relaxation, allowing your muscles to relax and your nerves to signal properly after contraction [NIH ODS].
Safety profile
The FDA received a total of 592,059 adverse event reports across all supplements, but specific reports for this Sundown Naturalist product are not available. For calcium specifically, high levels in the blood and urine can cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS] [FDA data].
Our recommendation
Data not available for the specific dose of this product, so we cannot recommend starting with it. Before taking any calcium supplement, you should talk to your doctor about your dietary calcium intake and whether you actually need a supplement. Be aware that calcium can reduce the absorption of medications like bisphosphonates, certain antibiotics, and levothyroxine [NIH ODS].
