NOW Magnesium & Potassium Aspartate
Brand: NOW · Form: CAPSULE [E0159]
Our assessment
The evidence shows that NOW Magnesium & Potassium Aspartate provides two essential minerals, but the data we have focuses on calcium, not the specific ingredients in this product. For calcium, the data confirms it is critical for bone mineralization and neuromuscular relaxation [NIH ODS]. However, we cannot make a direct assessment for magnesium or potassium aspartate based on the provided information, as specific data for these ingredients is not available.
How it works
Think of calcium as a structural foundation for your bones and a key player in nerve signaling. It supports bone density and mineral deposition, and it helps your muscles relax and nerves communicate properly [NIH ODS]. For the specific roles of magnesium and potassium aspartate in this product, data is not available.
Safety profile
The FDA received 592,059 total adverse event reports across all supplement categories, but specific report counts for this product are not available in the data provided [FDA data]. For calcium, high intakes might increase the risk of heart disease and prostate cancer, and high levels in the blood can cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS]. For side effects specific to this product, data is not available.
Our recommendation
If you are using this product for general mineral support, start by confirming your dietary needs with a healthcare professional. Be aware that calcium supplements can reduce absorption of medications like bisphosphonates, tetracycline and fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. For specific guidance on magnesium and potassium aspartate dosing or safety, data is not available, so consult your pharmacist or doctor before starting.
