NOW Sports Amino-9 Essentials Powder
Brand: NOW Sports · Form: POWDER [E0162]
Our assessment
The evidence shows that while calcium is a critical mineral for bone health, the supplement form carries specific risks that you need to understand before use. For the NOW Sports Amino-9 Essentials Powder, data on this specific product is limited, so our assessment relies on the general safety profile of calcium as an ingredient [NIH ODS].
How it works
Calcium acts as a master regulator for your body's structural and signaling systems. It supports bone density through mineralization and helps your muscles relax by aiding in nerve signaling [NIH ODS]. Think of it as the key that unlocks proper muscle function and keeps your skeleton strong.
Safety profile
FDA received 592,059 total adverse event reports across all products. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from excessive levels include 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]. Calcium can also reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Given the potential for serious side effects and medication interactions, do not take this supplement without first consulting your doctor. Have your blood calcium levels checked before starting. If you are on any medications, ask your pharmacist about timing your doses to avoid absorption issues [NIH ODS]. Data not available for the specific benefits of this product blend.
