NOW Zinc 50 mg
Brand: NOW · Form: TABLET [E0155]
Our assessment
The evidence shows that while this product is labeled as NOW Zinc 50 mg, the data provided is for calcium supplements, not zinc. Therefore, we cannot assess the specific benefits or risks of a 50 mg zinc supplement based on this information. For calcium, our assessment is that it is essential for bone health, but high intake carries significant risks [NIH ODS].
How it works
Calcium supports bone mineralization by helping deposit minerals into your skeleton, and it plays a role in neuromuscular relaxation by supporting muscle relaxation and nerve signaling [NIH ODS].
Safety profile
Data not available for zinc specifically. For calcium, FDA received 592,059 total adverse event reports across all supplements, though calcium-specific side effects include constipation, nausea, and abnormal heart rhythms at high levels [NIH ODS] [FDA data]. High calcium intakes might also increase the risk of heart disease and prostate cancer [NIH ODS].
Our recommendation
Data not available to recommend this specific zinc product. If you are considering a calcium supplement, be aware that it can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. Always consult your pharmacist or doctor before starting any new supplement, especially at a 50 mg dose of zinc, which exceeds the typical daily value for most adults.
