Radiance Plantinum Chelated Calcium Magnesium Zinc

Our assessment

The evidence shows that Radiance Plantinum Chelated Calcium Magnesium Zinc provides three key minerals that support bone health and muscle function. Our assessment is that this supplement can be a useful addition to your routine, but you need to be aware of the specific safety considerations for each ingredient. Data is not available on the exact dosage per serving from the provided label.

How it works

Think of calcium as the structural foundation for your bones, supporting bone density and mineral deposition [NIH ODS]. It also plays a critical role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS]. The combination with magnesium and zinc is intended to support this process, though specific data on their synergistic effects in this product is not available from the provided information.

Safety profile

FDA has received 592,059 total adverse event reports across all supplements. 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, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Our recommendation is to use this supplement only if you have confirmed through a blood test that you have a calcium or magnesium deficiency. Take it with food to improve absorption, and separate it from any medications by at least two hours to avoid interactions [NIH ODS]. Start with the lowest effective dose and monitor for any side effects like constipation or nausea. Consult your doctor before starting, especially if you have kidney disease or take prescription medications.
