Nature Made VitaMelts Zinc 15 mg Honey Lemon

Our assessment

The evidence shows that this product is designed to provide a foundation for bone health and nerve function. As a clinical pharmacist, I can tell you that calcium is a well-established mineral for these roles, but it is important to understand how to take it safely and effectively alongside your other medications [NIH ODS].

How it works

Think of calcium as a building block for your skeleton. It supports bone mineralization and density, and it also helps your muscles relax and your nerves signal properly. Without enough calcium, your body will pull it from your bones, which can weaken them over time [NIH ODS].

Safety profile

Data not available for this specific product. However, for calcium supplements in general, high intakes might increase the risk of heart disease and prostate cancer. High levels 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]. The FDA has received 592,059 total adverse event reports for all dietary supplements [FDA data].

Our recommendation

I recommend you start by discussing your total calcium intake from food and supplements with your doctor. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Take this supplement at a different time of day than those medications to avoid an interaction [NIH ODS].
