NOW Liquid Magnesium With Trace Minerals
Brand: NOW · Form: LIQUID, SUPPLEMENT FORM [E0165]
Our assessment
The evidence shows that magnesium is a critical mineral for your body, and this liquid form offers a unique delivery method. However, the data provided is incomplete. We have specific information on calcium from the NIH, but for the magnesium and trace minerals in this product, data on exact mechanisms and dosages is not available. Our assessment is that while magnesium is well-regarded for muscle and nerve function, you must rely on general safety principles for this specific formulation [NIH ODS].
How it works
Based on the data provided, we can only speak to the role of calcium, which is listed as a mineral. Think of calcium as a structural support for your bones and a regulator for your muscles and nerves. It supports bone density and mineral deposition, and it helps with neuromuscular relaxation and nerve signaling [NIH ODS]. For the specific magnesium and trace minerals in this product, detailed mechanisms are not available in the provided data.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product are not available. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Very high levels can cause poor muscle tone, poor kidney function, constipation, nausea, and abnormal heart rhythms [NIH ODS]. Additionally, calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. For the magnesium and trace minerals in this product, specific side effect data is not available.
Our recommendation
Start by reviewing the product label for the exact dosage of magnesium and trace minerals per serving, as this data was not provided. Because calcium can interfere with certain medications, take this supplement at a different time than any prescription drugs. If you have a history of kidney disease or heart problems, consult your doctor before starting. Our recommendation is to begin with the lowest suggested serving size on the label and monitor how you feel, as specific safety data for this product's blend is not available [NIH ODS] [FDA data].
