PureFormulas Magnesium Citrate
Brand: PureFormulas · Form: CAPSULE [E0159]
Our assessment
The evidence shows that magnesium citrate is a well-absorbed form of magnesium, but the specific data here focuses on calcium. For calcium, the research supports its role in bone health, but you need to be aware of significant risks at high intakes [NIH ODS].
How it works
Think of calcium as a key structural component for your bones and a critical player in your nervous system. It supports bone mineralization and density, and it helps your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, though specific counts for this product are not available. For calcium specifically, high intakes can cause constipation, nausea, and more serious issues like poor kidney function, abnormal heart rhythms, and a high risk of death from heart disease. High calcium levels may also increase the risk of prostate cancer [NIH ODS] [FDA data].
Our recommendation
Data not available for a specific dosage of this product. For calcium, you should be cautious with high doses. Calcium can reduce absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine, so take them at different times [NIH ODS].
