Our assessment
The evidence shows that calcium is a foundational mineral for bone health, but it requires careful management. For the product Nature's Sunshine Zinc, the primary ingredient data available is for calcium, not zinc. Our assessment is that you should verify the label to confirm the exact ingredients and dosages, as the FDA data on calcium provides important context for any supplement containing this mineral [NIH ODS].
How it works
Think of calcium as a structural builder and a signal messenger. It supports bone mineralization, helping to deposit minerals into your skeleton for density and strength. It also plays a key role in neuromuscular relaxation, aiding muscle relaxation and proper nerve signaling throughout your body [NIH ODS].
Safety profile
While calcium is essential, the FDA has received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Very high blood and urine levels 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 [FDA data] [NIH ODS].
Our recommendation
We recommend you first check the label of Nature's Sunshine Zinc to see if it contains calcium and at what dose. If calcium is present, do not exceed 2,000 mg total daily from all sources (food and supplements). Take calcium supplements separately from medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin, as calcium can reduce their absorption [NIH ODS]. For a zinc-specific product, data is not available for this specific formulation.
