Our assessment
The evidence shows that Kirkland Signature Calcium Chews Chocolate Flavored provide a well-known mineral for bone health. Our assessment: Calcium is essential for supporting bone density and mineralization, as well as for proper muscle relaxation and nerve signaling [NIH ODS]. This product is a convenient way for you to supplement your calcium intake, but it is important to understand both the benefits and the risks before starting.
How it works
Think of calcium as a structural building block for your bones and a key signaling molecule for your nerves and muscles. It directly supports bone mineralization and neuromuscular relaxation, meaning it helps your muscles relax after contracting and allows your nerves to send signals properly [NIH ODS]. Without enough calcium, your body will pull it from your bones, which can weaken them over time.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all dietary supplements, but specific report counts for this product are not available. For calcium specifically, some research suggests 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, a 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 several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. You should take calcium at a different time than these medications.
Our recommendation
Start by assessing your total daily calcium intake from food and other supplements to avoid exceeding the recommended upper limits. Be sure to take this supplement with food for best absorption. If you take any of the medications listed above, separate your calcium dose by at least two hours. Because of the potential risks associated with very high intakes, we recommend consulting with your healthcare provider to determine the right dose for your specific health needs [NIH ODS].
