H-E-B Magnesium Citrate 100 mg

Our assessment

The evidence shows that H-E-B Magnesium Citrate 100 mg is a straightforward mineral supplement. However, we must be clear: the data provided does not contain specific information about magnesium citrate itself. What we do have is data on calcium from the NIH ODS, which is a different mineral. Our assessment is that you are looking at a magnesium product, and we can only comment on the general category of mineral supplements based on the data available. The total adverse event reports for all supplements in the FDA database is 592,059, but this is a broad figure, not specific to this product [FDA data].

How it works

While we lack specific data on magnesium citrate, we can look at how minerals generally function. Based on the data for calcium, a related mineral, it supports bone mineralization and neuromuscular relaxation, meaning it helps with bone density and muscle relaxation [NIH ODS]. For magnesium specifically, you would expect it to play a key role in muscle function and energy production, but the data provided does not confirm this mechanism for this product.

Safety profile

The safety data provided is for calcium, not magnesium. For calcium, high intakes can cause constipation, nausea, weight loss, extreme tiredness, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. It can also reduce the absorption of medications like bisphosphonates, certain antibiotics, and levothyroxine [NIH ODS]. For H-E-B Magnesium Citrate specifically, side effect data is not available. The total adverse event count of 592,059 is not broken down by product or ingredient [FDA data].

Our recommendation

Without specific data on H-E-B Magnesium Citrate 100 mg, we cannot make a confident recommendation for this product. We advise you to consult your healthcare provider before starting any new supplement, especially if you take other medications. If you are considering this for a specific health concern, ask your pharmacist or doctor for guidance based on your personal health history. Data on this exact product's benefits and risks is not available.
