Our assessment
Our assessment: Based on the data provided, we cannot evaluate KAL Magnesium Glycinate 400 specifically, as the ingredient data available is for calcium, not magnesium. The evidence shows that calcium is essential for bone mineralization and neuromuscular relaxation [NIH ODS]. However, because the product label lists magnesium glycinate, we must note that data for magnesium is not available in this specific dataset. You should be aware that the information below pertains to calcium, which is not the primary ingredient in your supplement.
How it works
Think of calcium as a structural builder — it supports bone density and mineral deposition, and it also helps your muscles relax and your nerves signal properly [NIH ODS]. For magnesium glycinate, which is the ingredient in your product, data on its specific mechanism is not available here. You may want to consult a healthcare provider for details on how magnesium supports muscle function and sleep.
Safety profile
For calcium, the FDA has received a total of 592,059 adverse event reports across all supplements. Side effects of high calcium intake include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. High levels in the blood and urine can also cause poor muscle tone, poor kidney function, and low phosphate levels [NIH ODS]. However, these side effects are for calcium, not magnesium. Data on side effects specific to magnesium glycinate 400 is not available.
Our recommendation
Our recommendation: Because the data provided is for calcium and not for magnesium glycinate, we cannot make a confident recommendation for this specific product. You should consult your pharmacist or doctor before starting KAL Magnesium Glycinate 400, especially if you take medications, as calcium (a different mineral) can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. For magnesium glycinate, ask your healthcare provider for guidance based on your individual needs.
