Our assessment
The evidence shows that NOW Sports Amino Complete contains calcium, a mineral well-documented for its role in bone health. However, the data on calcium supplementation reveals important safety considerations you should be aware of before adding this product to your routine [NIH ODS].
How it works
Calcium acts as a master regulator for your body's structural and signaling systems. It supports bone density through bone mineralization and promotes neuromuscular relaxation by aiding nerve signaling and muscle relaxation [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, some research suggests that high 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] [FDA data]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our assessment: you should approach this supplement with caution. The potential risks from high calcium intake, including cardiovascular concerns and medication interactions, are significant. Data not available for the specific dosing of calcium in this product. Before taking NOW Sports Amino Complete, consult your healthcare provider to evaluate your dietary calcium intake and discuss potential risks, especially if you take prescription medications [NIH ODS].
