Rugby Melatonin 3 mg
Brand: Rugby · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that while the product is labeled as Rugby Melatonin 3 mg, the data provided only contains information on the ingredient Calcium. There is no data on melatonin itself, so we must evaluate the calcium content. Our assessment is that calcium is essential for bone health, but you need to be aware of significant safety risks and medication interactions before taking this supplement [NIH ODS].
How it works
Think of calcium as a structural builder and signal conductor. It supports bone mineralization and density, which is critical for your skeletal strength. Additionally, it plays a role in neuromuscular relaxation, helping your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
The FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from high calcium levels include 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]. Data on side effects specific to Rugby Melatonin 3 mg is not available.
Our recommendation
We recommend caution. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Consult your doctor before taking this supplement, especially if you take any of these medications. Start with the lowest effective dose and do not exceed the RDA without medical supervision [NIH ODS].
