Our assessment
The evidence shows that the primary ingredient in this product, calcium, is essential for bone health, but the data on its benefits and risks requires a careful look. Our assessment is that you should not take this supplement without first reviewing your dietary calcium intake and discussing it with your healthcare provider, as high intakes carry real risks.
How it works
Think of calcium as a structural builder for your bones. It works through bone mineralization, supporting bone density and mineral deposition. It also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
Safety is a significant concern. The FDA has received a total of 592,059 adverse event reports across all supplements, and the data for calcium specifically notes that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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
Do not start this supplement unless you have confirmed a calcium deficiency through a healthcare professional. Given the potential for serious side effects and medication interactions, it is essential to get calcium from food first and only supplement under medical guidance [NIH ODS]. For most people, a balanced diet provides adequate calcium. Data not available on the specific dosage of this Sundown Naturals product.
