Our assessment
The evidence shows that this product provides calcium, which plays a critical role in bone health. However, based on the data provided, we cannot confirm the specific benefits of the "Magnesium Citrate Softgels" listed, as the ingredient data available is for calcium. Our assessment is that you should verify the label to ensure you are taking the intended mineral for your health goals. Data on magnesium specifically for this product is not available.
How it works
Think of calcium as a structural foundation for your bones and a key player in nerve function. It supports bone mineralization and density, and helps with muscle relaxation and nerve signaling [NIH ODS]. If you are taking this for magnesium's effects on muscle cramps or relaxation, please note that the data provided does not cover that ingredient.
Safety profile
FDA received 592,059 total adverse event reports for this product category. While the specific side effects for this product are not listed, high calcium intake can lead to serious issues including constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data]. You should be aware that calcium supplements can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Start by checking the product label to confirm it contains the ingredient you need. If you are seeking magnesium for muscle relaxation, this product may not be appropriate based on the available data. For calcium, take it with food and separate from other medications by at least 2 hours. Do not exceed the recommended dose without consulting your healthcare provider [NIH ODS].
