Our assessment
The evidence shows that the calcium in Metagenics Arginine Plus plays a specific role in supporting your body. Our assessment: based on the data provided, calcium is included for its role in bone mineralization and neuromuscular relaxation [NIH ODS]. However, the data does not specify the amount of calcium in this product, so we cannot confirm if it provides a meaningful dose for these benefits.
How it works
Think of calcium as a structural and signaling mineral. It supports bone density and mineral deposition, which helps keep your skeleton strong. It also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly after contraction [NIH ODS].
Safety profile
Data not available for this specific product. For calcium in general, some research suggests that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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 [NIH ODS]. The FDA received a total of 592,059 adverse event reports across all dietary supplements, but the number specific to Metagenics Arginine Plus is not available [FDA data].
Our recommendation
Data on the exact calcium dose in this product is not available, so we cannot recommend it for its calcium content alone. If you are taking medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, or phenytoin, be aware that calcium can reduce their absorption [NIH ODS]. Speak with your doctor before adding this supplement to your routine.
