Rugby Calcium 600
Brand: Rugby · Form: TABLET [E0155]
Our assessment
Our assessment: Calcium is a foundational mineral for bone health, and this product provides a standard 600 mg dose. The evidence shows that adequate calcium intake is essential for maintaining bone density and supporting muscle and nerve function [NIH ODS]. However, you should be aware that the data on high-dose calcium supplements includes important safety considerations that affect your heart and kidney health [NIH ODS].
How it works
Think of calcium as a building block for your skeleton. It supports bone mineralization, which is the process of depositing minerals into your bone matrix to keep them strong [NIH ODS]. Calcium also plays a key role in neuromuscular relaxation, helping your muscles relax properly and your nerves send signals efficiently [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplement categories, though specific report counts for this product are not available. High calcium intakes from supplements may increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from excessively high levels include constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by assessing your total daily calcium intake from food and other supplements. Most adults need 1,000 to 1,200 mg per day, so this 600 mg tablet can help fill a gap [NIH ODS]. Take this supplement with food and separate it from any prescription medications by at least two hours to avoid absorption issues [NIH ODS]. Do not exceed the recommended dose without consulting your healthcare provider, especially if you have a history of kidney stones or heart conditions [NIH ODS].
