Rugby Calcium 600-D
Brand: Rugby · Form: TABLET [E0155]
Our assessment
The evidence shows that Rugby Calcium 600-D provides a combination of calcium and vitamin D to support bone health. Based on the data, this supplement is most appropriate for individuals who have a confirmed need for additional calcium, typically when dietary intake is insufficient [NIH ODS].
How it works
Think of calcium as a key structural component for your bones, supporting bone density and mineral deposition. It also plays a role in neuromuscular relaxation, helping with muscle and nerve signaling. The vitamin D in this product aids calcium absorption [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports for this product category. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer. High levels of calcium 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 [FDA data] [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend you speak with your healthcare provider before starting this supplement, especially if you take any medications that interact with calcium. Data not available on the exact RDA or optimal dosage for this specific product, so you should not exceed the label's directions [NIH ODS].
