Our assessment
The evidence shows that this product’s key ingredient, Calcium, is well-studied for bone health, but you should be aware of important safety limits. Our assessment: for most adults, getting calcium from food is preferable, and you should only consider this supplement if your diet is consistently low in dairy or fortified foods.
How it works
Calcium acts as a master regulator for your skeleton and nerves. It supports bone mineralization and density, and it helps your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Signs of too much calcium include 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 absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Do not exceed the tolerable upper intake level for calcium without medical supervision. If you take any of the medications listed above, separate calcium intake by at least 2 hours. Data not available on the specific amino acid blend in this product, so rely on your healthcare provider to assess if additional calcium is right for you [NIH ODS].
