Our assessment
Our assessment: Calcium is a foundational mineral for bone health, but the evidence shows you need to be precise with your dosage. The product supplies 600 mg of calcium per serving, which is a significant portion of the recommended daily intake for most adults [NIH ODS]. For many people, this is an appropriate amount to help meet your daily needs, especially if your diet is low in dairy or fortified foods [NIH ODS].
How it works
Think of calcium as the structural building block for your skeleton. It is essential for bone mineralization, helping to deposit minerals into your bone matrix to keep them dense and strong [NIH ODS]. Beyond your bones, calcium acts as a master signaling molecule — it supports muscle relaxation after contraction and is critical for proper nerve signaling throughout your body [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplements, though specific data for this product is not available. The safety data shows that high calcium intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Too much calcium in your 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
Take this supplement with food for better absorption. You should separate your dose from any medications listed above by at least 2 hours [NIH ODS]. Do not exceed 2,000 mg of total calcium per day from all sources (food and supplements) without a doctor's guidance [NIH ODS]. If you have a history of kidney stones, heart disease, or prostate issues, speak with your healthcare provider before starting this supplement [NIH ODS].
