Kirkman Buffered Magnesium Glycinate
Brand: Kirkman · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that Kirkman Buffered Magnesium Glycinate is intended to provide magnesium, but the data provided focuses on calcium, not magnesium. Based on the ingredient calcium, our assessment is that this product supports bone health and nerve function, but you need to be cautious about total calcium intake from all sources [NIH ODS].
How it works
Think of calcium as a structural builder — it supports bone density and mineral deposition for strong bones, and it helps your muscles relax and nerves signal properly [NIH ODS]. However, data on the specific "magnesium glycinate" or "buffered" formulation is not available in the provided information.
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from high calcium levels 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]. Data not available for side effects specific to this product’s formulation.
Our recommendation
Start by checking your total calcium intake from food and other supplements. Do not exceed the tolerable upper intake level without medical supervision. Be aware that calcium can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS]. Our recommendation is to consult your doctor before starting this product, especially if you take any of these medications.
