Carlson Magnesium 350 mg

Our assessment

The evidence shows that Carlson Magnesium 350 mg is a straightforward magnesium supplement. Data on the specific ingredient calcium is provided, but for this product, the primary ingredient is magnesium. Our assessment is that magnesium is a well-studied mineral for supporting muscle relaxation and nerve signaling [NIH ODS]. However, the specific data provided does not include magnesium-specific findings, so we must rely on the general safety framework for minerals.

How it works

Think of magnesium as a relaxation mineral. It plays a key role in neuromuscular relaxation and nerve signaling, helping your muscles unwind after activity and supporting calm nerve function [NIH ODS]. While the provided data focuses on calcium, magnesium works in a complementary way to help regulate these processes in your body.

Safety profile

FDA received a total of 592,059 adverse event reports across all supplement categories. For this specific product, individual side effect data is not available. Based on general mineral safety, high levels of minerals in the blood can cause poor muscle tone, constipation, nausea, and extreme tiredness [NIH ODS]. However, side effect data specific to this magnesium product is not provided.

Our recommendation

Start with the recommended serving on the label. Magnesium supplements are generally well-tolerated, but you should be aware that taking them with food can reduce stomach upset. Data not available on specific interactions for this product, but calcium supplements can reduce the absorption of medications like bisphosphonates and certain antibiotics [NIH ODS]. Consult your pharmacist or doctor before starting this supplement, especially if you take prescription medications.
