Highland Laboratories Cal-Mag Zinc

Brand: Highland Laboratories · Form: CAPSULE [E0159] On Market

Our assessment

Our assessment: Highland Laboratories Cal-Mag Zinc is a combination supplement providing calcium, magnesium, and zinc. The evidence shows that calcium is crucial for bone health, but you need to be aware of the specific risks and interactions associated with this mineral [NIH ODS].

How it works

Think of calcium as a building block for your bones. It supports bone density through a process called bone mineralization, and it also helps your muscles relax and your nerves signal properly [NIH ODS].

Safety profile

FDA received 592,059 adverse event reports total across all supplements, but specific data for this product is not available. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels in your blood 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].

Our recommendation

Our recommendation: Be cautious with calcium supplements. They can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Always take this supplement at a different time than these medications. Data not available for specific dosing recommendations for this product.
