Douglas Laboratories Zinc Lozenges
Brand: Douglas Laboratories · Form: LOZENGE [E0174]
Our assessment
The evidence shows that Douglas Laboratories Zinc Lozenges are primarily a source of the mineral zinc, but the data provided does not include specific information on zinc itself — only on calcium. For this product, we cannot make a direct assessment on zinc efficacy or dosing based on the data available. Data not available on zinc-specific benefits for this product.
How it works
Based on the ingredient data provided, the mineral in this supplement is calcium. Calcium supports bone mineralization by helping maintain bone density and mineral deposition, and it also aids neuromuscular relaxation by supporting muscle relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements, but specific report counts for this product are not available. For calcium, high intakes might increase the risk of heart disease and prostate cancer. High blood and urine levels of calcium 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 provided data focuses on calcium rather than zinc, we cannot give a specific recommendation for this product as a zinc lozenge. If you are taking this for zinc, consult your healthcare provider for appropriate dosing. For calcium, do not exceed recommended intakes without medical supervision, and separate calcium supplements from certain medications by at least 2 hours [NIH ODS].
