Our assessment focuses on one key ingredient, calcium, for which data is available. Calcium is essential for bone health, but the specific benefits and risks of this exact product formulation depend on your individual dietary needs and health status. You should not assume this product is right for you without reviewing your current diet and supplement intake.
How it works

Think of it as a foundational mineral that your body uses every day for structural support and cellular communication.
Safety profile
The FDA has received a total of 592,059 adverse event reports for all dietary supplements, though specific report counts for this product are not available. For calcium specifically, safety data shows that high intakes might increase the risk of heart disease and prostate cancer. 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]. Additionally, calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available on the exact dosage of calcium in this product. Our recommendation is to check the label for the specific calcium amount and compare it to your total daily intake from food and other supplements. Do not exceed the tolerable upper intake level for calcium without medical supervision. If you take any of the listed medications, take this supplement at a different time of day to avoid absorption issues. Consult your healthcare provider before starting this supplement, especially if you have a history of kidney stones, heart disease, or are on thyroid or antibiotic medications [NIH ODS].
