GNC Ultra Zinc Lozenge Orange
Brand: GNC · Form: LOZENGE [E0174] On Market
Our assessment
The evidence shows that GNC Ultra Zinc Lozenge Orange contains calcium, and it is important to understand the full profile of this mineral before you start taking it. While calcium is essential for bone health, the data does not specify the exact amount of calcium in each lozenge, which is a significant limitation [NIH ODS]. Our assessment is that you should proceed with caution and verify the specific dosage on the product label before use.
How it works
Think of calcium as a structural and signaling powerhouse in your body. It supports bone mineralization by helping deposit minerals into your bone matrix, and it is critical for neuromuscular relaxation, meaning it helps your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports for products in this category. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels in the blood and urine 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] [FDA data]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend that you check the product label for the exact amount of calcium per lozenge, as this data is not provided here. If you are taking any of the listed medications, take this lozenge at least two hours apart from those doses to avoid absorption issues [NIH ODS]. Start with a low intake and monitor for any side effects like constipation or nausea. If you have a history of kidney stones, heart disease, or prostate cancer, consult your doctor before using this product [NIH ODS].
