Carlson Magnesium 350 mg

Our assessment

The evidence shows that Carlson Magnesium 350 mg is a straightforward mineral supplement. However, the data provided only covers calcium, not magnesium. Our assessment is that the product label indicates 350 mg of magnesium per serving, but no specific clinical studies or safety data for this exact product are available in the provided information. For general mineral supplementation, we rely on established data for related minerals like calcium [NIH ODS].

How it works

While the data does not include a mechanism of action for magnesium, calcium—another essential mineral—works through bone mineralization by supporting bone density and mineral deposition, and through neuromuscular relaxation by supporting muscle relaxation and nerve signaling [NIH ODS]. You should note that magnesium and calcium often work together in the body, but specific details for magnesium are not available in this dataset.

Safety profile

Data not available for magnesium-specific adverse events in the provided information. The FDA has received a total of 592,059 adverse event reports across all supplements, but this number is not specific to Carlson Magnesium 350 mg [FDA data]. For calcium, side effects from high intake include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease. However, these calcium-specific side effects do not apply directly to this magnesium product [NIH ODS].

Our recommendation

Without specific safety or efficacy data for this Carlson magnesium product, our recommendation is cautious. You should consult your healthcare provider before starting any new supplement, especially if you take medications, as calcium supplements can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. We cannot make a confident recommendation for this specific product based solely on the data provided.

Supplement labels contain several key sections regulated by the FDA:

• Serving Size — The recommended amount per dose. Always check this — some products require multiple capsules per serving.
• Amount Per Serving — Shows the quantity of each nutrient in the product, typically in IU (International Units), mg (milligrams), or mcg (micrograms).
• % Daily Value (%DV) — Indicates how much a nutrient in a serving contributes to a daily diet. 5% DV or less is low; 20% DV or more is high.
• Other Ingredients — Lists inactive ingredients like fillers, binders, and capsule materials (e.g., gelatin, cellulose, magnesium stearate).
• Suggested Use — The manufacturer's recommended directions for taking the supplement, including timing and dosage.
