Our assessment
The evidence shows that the calcium found in NOW Sports Amino Complete plays a well-established role in bone health. Data confirms that calcium is essential for bone mineralization and neuromuscular relaxation, supporting both bone density and muscle function [NIH ODS]. However, there are important safety considerations you need to be aware of before adding this supplement to your routine.
How it works
Think of calcium as a structural building block for your skeleton. It works by supporting bone density and mineral deposition, which helps keep your bones strong. At the same time, calcium supports muscle relaxation and nerve signaling, helping your muscles recover after exercise [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplement categories. For calcium specifically, high intakes can pose risks. 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 [NIH ODS]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for specific serving sizes or daily values for this product. Because calcium has significant potential risks and interactions, we recommend you consult your healthcare provider before starting this supplement, especially if you take any medications for bone health, thyroid conditions, or infections. Your pharmacist or doctor can help you determine if this product is appropriate for your individual health needs [NIH ODS].
