Floradix Calcium Magnesium

Our assessment

The evidence shows that Floradix Calcium Magnesium is a supplement designed to support your bone health and muscle function. Our assessment is based on the calcium content, which is the primary active ingredient with available data [NIH ODS]. For a general audience seeking a reliable calcium source, this product can be a reasonable option, but you must be aware of the specific dosages and potential risks outlined below.

How it works

Think of calcium as a structural building block for your bones. It supports bone density and mineral deposition, which is crucial for maintaining strong skeletal health as you age [NIH ODS]. Additionally, calcium plays a key role in neuromuscular relaxation, meaning it helps your muscles relax and your nerves signal properly after contraction [NIH ODS]. This dual action makes it important for both your skeleton and your daily physical function.

Safety profile

FDA received 592,059 total adverse event reports across all supplements, though specific reports for this product are not isolated. The data for calcium indicates that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Very high levels of calcium in your blood and urine can cause 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]. You should also know that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. For specific side effects and report counts for this exact product, data is not available.

Our recommendation

We recommend you start by checking the label for the exact amounts of calcium and magnesium per serving, as the provided data does not specify the dosage. Based on the calcium data, take this supplement with food to aid absorption, and separate it from any medications like thyroid hormone or antibiotics by at least two hours [NIH ODS]. Do not exceed the recommended serving size, and consult your doctor if you have a history of kidney stones, heart disease, or are taking any prescription medications. If you experience nausea, constipation, or unusual fatigue, stop use and speak with a healthcare professional [NIH ODS].
