Our assessment
The evidence shows that NOW Sports Amino Complete is a multi-ingredient supplement. Our assessment focuses on the calcium content, as that is the only ingredient with detailed data provided. For the other ingredients, data is not available. Calcium is essential for bone health, but exceeding the recommended intake carries specific risks you should know about [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone density through a process called bone mineralization and is also critical for proper muscle relaxation and nerve signaling [NIH ODS]. Without enough calcium, your body will leach it from your bones, which can weaken them over time.
Safety profile
For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from excessive calcium in the blood and urine include poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms [NIH ODS]. The FDA has received 592,059 total adverse event reports across all supplements, though this number is not specific to this product alone [FDA data]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Before starting this supplement, check your total calcium intake from food and other supplements. If you take medications for thyroid conditions, osteoporosis, or bacterial infections, speak with your doctor about proper timing to avoid absorption issues [NIH ODS]. For most adults, a balanced diet provides adequate calcium, so use this product cautiously to avoid exceeding safe upper limits.
