Natural Factors Zinc Citrate 50 mg
Brand: Natural Factors · Form: TABLET [E0155]
Our assessment
Our assessment: The evidence shows that calcium is essential for your bone health and nerve function, but this specific product, Natural Factors Zinc Citrate 50 mg, contains zinc, not calcium. Based on the data provided, we cannot evaluate this product for calcium-related benefits because the ingredient listed is zinc. Data not available for this product’s specific effects on bone mineralization or neuromuscular relaxation as related to calcium [NIH ODS].
How it works
Calcium supports your body by aiding bone density and mineral deposition, as well as supporting muscle relaxation and nerve signaling [NIH ODS]. However, since this product is a zinc supplement, these mechanisms do not apply directly. You should look for a calcium supplement if you need to address those functions, as zinc has a different role in the body.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, but specific data for this product is not available. For calcium, high intakes might increase the risk of heart disease and prostate cancer, and high levels in the blood and urine can cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Because this is a zinc product, these calcium-specific side effects are not directly applicable to your use.
Our recommendation
Our recommendation: If you are seeking calcium for bone health, this zinc product is not appropriate. You should choose a calcium supplement specifically. Before taking any supplement, check with your healthcare provider, as calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. For this product, data not available for a specific recommendation.
