Rugby Zinc & C Lozenges
Brand: Rugby · Form: LOZENGE [E0174]
Our assessment
The evidence shows that Rugby Zinc & C Lozenges contain calcium, which is a mineral with well-documented benefits for bone health. However, the specific formulation of this product means you are primarily getting a supplement that supports bone mineralization and nerve signaling [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It works through bone mineralization, helping to support bone density and mineral deposition, and it also plays a role in neuromuscular relaxation by supporting muscle relaxation and nerve signaling [NIH ODS].
Safety profile
Data not available for this specific product. However, for calcium generally, 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]. The FDA has received a total of 592,059 adverse event reports across all supplements, but report counts for this specific product are not provided [FDA data].
Our recommendation
For general bone health, consider calcium from food sources first, as the safety profile for high-dose supplementation has significant risks. If you choose to use this lozenge, be aware that calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Speak with your doctor before starting, especially if you take any of these medications.
