NOW Sports Amino-9 Essentials
Brand: NOW Sports · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that NOW Sports Amino-9 Essentials is a product designed to provide a blend of amino acids, but our assessment focuses on its key ingredient, Calcium. Data indicates that calcium is essential for bone mineralization and neuromuscular relaxation [NIH ODS]. However, the data provided does not include specific studies or clinical trial results for this specific product formulation, so we must rely on general ingredient data.
How it works
Think of calcium as a structural building block for your skeleton, supporting bone density and mineral deposition. It also plays a critical role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly after contraction [NIH ODS]. Without adequate calcium, your body may pull it from your bones to support these vital functions.
Safety profile
Data not available for this specific product's side effects. However, for the ingredient calcium, high intakes may increase the risk of heart disease and prostate cancer. High levels in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. The FDA has received a total of 592,059 adverse event reports across all supplement products, but specific report counts for this product are not provided [FDA data]. Calcium can also reduce the absorption of several medications including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation is to be cautious. Before taking this supplement, consult your healthcare provider to determine if you have a true calcium deficiency. Do not exceed the recommended daily intake without medical supervision, especially if you take medications listed above. Choose a product with a clear third-party verification seal when possible [NIH ODS].
