Natrol Zinc Natural Pineapple Flavor
Brand: Natrol · Form: TABLET [E0155] On Market
Our assessment
Our assessment: For the specific product Natrol Zinc Natural Pineapple Flavor, the evidence shows that the primary ingredient listed is not zinc but calcium, based on the data provided. This is a significant mismatch between the product name and the labeled ingredient. We recommend you verify the label carefully before use, as the intended benefit of zinc supplementation is not supported by the available data for this product.
How it works
If the product contains calcium as indicated, it works through bone mineralization, helping to support bone density and mineral deposition. It also supports neuromuscular relaxation, aiding muscle relaxation and nerve signaling [NIH ODS]. Data for zinc's mechanism is not available for this specific product.
Safety profile
Safety profile: The FDA has received 592,059 total adverse event reports across all supplements, but specific report counts for this product are not available. If this product contains calcium, side effects from high levels can include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. High calcium intakes might also increase the risk of heart disease and prostate cancer [NIH ODS]. Data for side effects specific to zinc in this product is not available.
Our recommendation
Our recommendation: Because the data shows the labeled ingredient is calcium rather than zinc, we cannot recommend this product for zinc supplementation. If you are seeking a zinc supplement, choose a product where zinc is clearly listed as the active ingredient. If you choose to use this product for calcium, be aware that calcium can reduce the absorption of medications including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Always consult your pharmacist or doctor before starting a new supplement.
