PhysioLogics Magnesium Chelate
Brand: PhysioLogics · Form: SUPPLEMENT FORM, OTHER [E0172]
Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health. However, our assessment is that you should be cautious with calcium supplementation. The data on high intakes is concerning, as some research suggests it might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone density and mineral deposition through a process called bone mineralization. Additionally, calcium plays a role in neuromuscular relaxation, helping your muscles relax and nerves signal properly [NIH ODS].
Safety profile
Safety data is critical here. High levels of calcium in your blood and urine can cause serious issues, including 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]. A total of 592,059 adverse event reports have been filed with the FDA across all products in this category [FDA data]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation is to prioritize getting calcium from food sources first. If you do use a supplement, do not exceed the daily recommended intake without a doctor's guidance. Be sure to take calcium supplements separately from any prescription medications to avoid absorption issues [NIH ODS].
