Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health. For a general audience, calcium supplements can be useful if your diet is low in dairy or fortified foods, but the data reveals important safety considerations you should know before starting [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone density and mineralization, and also plays a role in neuromuscular relaxation, helping your muscles and nerves signal properly [NIH ODS]. Your body cannot produce calcium on its own, so you must get it from food or supplements.
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Excess calcium in the blood or urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, 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
Start by assessing your dietary calcium intake before supplementing. Do not exceed the tolerable upper intake level without medical supervision. If you take any of the listed medications, separate calcium intake by at least two hours. Data on optimal dosing for this specific product is not available, so consult your healthcare provider for personalized advice [NIH ODS].
