Brand: Natural Factors · Form: TABLET [E0155]
Our assessment
The evidence shows that while calcium is essential for bone health, you should be cautious with supplementation. For the product Natural Factors Zinc Chelate 25 mg, the primary ingredient data available is for calcium, not zinc. Data not available for zinc specifically from the provided sources. Based on the calcium data, this mineral is critical for bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone density and mineral deposition, and it also plays a key role in muscle relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received 592,059 adverse event reports total for all products in the database. For calcium specifically, safety concerns include that high intakes might increase the risk of heart disease and prostate cancer. High blood and urine levels 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]. Calcium can also reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Because the data provided is for calcium, not zinc, we cannot make a specific recommendation for Natural Factors Zinc Chelate 25 mg. If you are taking this product for zinc, data not available. If you are considering calcium, get your intake from food first and talk to your doctor before supplementing, especially if you take any of the medications listed above [NIH ODS].
