KAL Magnesium Glycinate 400
Brand: KAL · Form: TABLET [E0155]
Our assessment
The evidence shows that KAL Magnesium Glycinate 400 is a product marketed for its magnesium content. However, the data provided exclusively covers the ingredient Calcium, not Magnesium. Our assessment is that based on the available data, we cannot confirm the efficacy, mechanism, or safety of this specific magnesium product. The data provided is for a different mineral entirely.
How it works
Based on the data provided for Calcium, the mechanism involves bone mineralization to support bone density and neuromuscular relaxation for nerve signaling [NIH ODS]. This data does not apply to Magnesium Glycinate. Data not available on how the specific ingredient in this product works.
Safety profile
The FDA has received 592,059 total adverse event reports across all products in their database [FDA data]. For the ingredient Calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in the blood and urine can cause 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]. These side effects are for Calcium, not the magnesium glycinate in this product. Data not available on side effects specific to this product.
Our recommendation
We cannot recommend KAL Magnesium Glycinate 400 based on the data provided, as it pertains to Calcium, not Magnesium. For any supplement, you should consult with your healthcare provider. Calcium supplements may reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. This interaction data is for Calcium, not Magnesium. Data not available to support a recommendation for this specific product.
