Swanson Premium Brand Liquid Calcium & Magnesium
Brand: Swanson Premium Brand · Form: SOFTGEL CAPSULE [E0161]
Our assessment
The evidence shows that calcium is a critical mineral for bone health, but this product's combination of calcium and magnesium requires careful consideration. Data indicates that calcium supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, we need to look closely at your individual needs and potential risks before recommending this supplement.
How it works
Calcium works as a structural component for your bones and teeth, while also playing a key role in muscle relaxation and nerve signaling [NIH ODS]. Think of it as the building block your body uses to keep your skeleton strong and your muscles functioning properly. The magnesium in this formula works alongside calcium to support these processes.
Safety profile
FDA received 592,059 adverse event reports for this product category. You should be aware that high calcium intake may increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from excessive calcium include constipation, nausea, weight loss, extreme tiredness, frequent urination, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available for specific side effect report counts for calcium alone.
Our recommendation
Start by assessing your current dietary calcium intake from food sources. If you take this supplement, separate it from your medications by at least 2 hours to avoid absorption issues [NIH ODS]. Do not exceed the recommended dose on the label, and consult your healthcare provider if you have a history of kidney stones, heart disease, or take any of the medications listed above. This product may be appropriate for you if your diet is low in calcium and magnesium, but it is not a substitute for a balanced diet.
