Solgar Magnesium Citrate

Our assessment

The evidence shows that Solgar Magnesium Citrate is a well-absorbed form of magnesium, but the specific product data for this supplement is limited. Based on the available data for the ingredient calcium, which is not the primary ingredient in this product, we must be careful not to extrapolate. For Solgar Magnesium Citrate specifically, data on its mechanism and benefits is not provided. Our assessment is that while magnesium citrate is a reputable form, we cannot confirm specific health claims for this product without its own ingredient data.

How it works

For the ingredient calcium, the mechanism involves supporting bone density and mineral deposition, as well as supporting muscle relaxation and nerve signaling [NIH ODS]. However, for Solgar Magnesium Citrate, how it works in the body is not detailed in the provided data. Magnesium citrate is generally known to be well-absorbed, but specific mechanisms for this product are not available from the data provided.

Safety profile

Based on FDA data, there were 592,059 total adverse event reports across all supplements [FDA data]. For the ingredient calcium, side effects from high levels include poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. For Solgar Magnesium Citrate specifically, side effect data is not available. The data also shows that calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].

Our recommendation

We cannot make a specific recommendation for Solgar Magnesium Citrate based solely on the data provided. The data does not include the mechanism, benefits, or side effects for this specific product. For the ingredient calcium, which is not in this product, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Because the critical data for Solgar Magnesium Citrate is missing, we recommend consulting with your healthcare provider before starting any new supplement, as we cannot confirm its safety or efficacy from the information provided.
