Kirkman Magnesium Glycinate Bio-Max Series
Brand: Kirkman · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that Kirkman Magnesium Glycinate Bio-Max Series contains calcium, a mineral essential for bone health and muscle function. Our assessment is that while calcium is a foundational nutrient, the data on high intake raises important safety considerations you should know about before starting this supplement [NIH ODS].
How it works
Think of calcium as a structural building block for your bones and a signal regulator for your muscles and nerves. It supports bone mineralization and density, and it helps your muscles relax after contraction while aiding nerve signaling throughout your body [NIH ODS].
Safety profile
Data not available for this specific product's adverse events. For calcium overall, FDA has received 592,059 total adverse event reports. High calcium intakes may increase the risk of heart disease and prostate cancer. Elevated levels in blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data]. Calcium can also reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
You should only take this supplement if you have a confirmed need for additional calcium, such as a diagnosed deficiency or a diet low in dairy. Because the data shows risks from high intake, do not exceed the recommended dose on the label. If you take any medications listed above, separate your doses by at least two hours to prevent absorption issues [NIH ODS].
