Our assessment
The evidence shows that MusclePharm Arnold Iron Cre3 Watermelon, based on its label, contains calcium, a mineral that supports bone density and muscle relaxation [NIH ODS]. However, we cannot assess the full efficacy of this specific product because data on its complete ingredient profile is not available. Our assessment is that you should approach this supplement with caution, focusing on the known risks and benefits of calcium, which is the only ingredient with sufficient data here [NIH ODS].
How it works
Think of calcium as a master regulator for your muscles and bones. It supports bone mineralization, helping to maintain bone density, and it aids neuromuscular relaxation, which is essential for proper muscle function and nerve signaling [NIH ODS]. Without adequate calcium, your body may pull it from your bones, which can weaken them over time [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories, but specific report counts for this product are not available [FDA data]. Regarding calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from very high calcium levels include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, 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
We recommend you do not take this supplement without first consulting your doctor. Because data on the full ingredient list is not available, we cannot confirm this product is safe or effective. If you are considering it for calcium, get your blood levels checked first, and be aware of the serious side effects and medication interactions associated with high calcium intake [NIH ODS]. Choose a simpler, well-studied calcium supplement if needed, and always follow the RDA guidance from your healthcare provider [NIH ODS].
