Rugby Calcium Lactate 10 Grams (648 mg)
Brand: Rugby · Form: TABLET [E0155]
Our assessment
The evidence shows that Rugby Calcium Lactate 10 Grams (648 mg) is a calcium supplement intended to support bone health. As a clinical pharmacist, I advise you to understand that calcium is essential for your body, but getting the dose right is critical. This product provides a specific amount of calcium, and your total intake from food and other supplements must be carefully managed to avoid risks [NIH ODS].
How it works
Calcium is a master regulator for your body. Think of it as the key mineral that supports bone mineralization, helping to build and maintain strong bone density. It also plays a vital role in neuromuscular relaxation, which means it helps your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
Data not available for this specific product's side effect reports. The FDA has received 592059 total adverse event reports for all calcium products. High levels of calcium in your 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]. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
Our recommendation
Before taking this supplement, you must consider that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. I recommend you speak with your doctor or pharmacist about your total daily calcium intake from all sources, including food, to ensure you are not exceeding safe levels. Do not take this supplement without a clear understanding of your individual needs and medication interactions.
