Our assessment
The evidence shows that Swanson Premium Brand Bio-Fiber 750 mg contains calcium as its primary active ingredient. Based on the data provided, this supplement supports bone density and muscle relaxation [NIH ODS]. However, you should be aware that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton — it supports bone mineralization and density, which is critical for maintaining strong bones as you age [NIH ODS]. Additionally, calcium plays a role in neuromuscular relaxation, helping your muscles and nerves signal properly [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplements, though specific report counts for this product are not available. The data indicates that high levels of calcium in the blood and urine can cause constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start with a single 750 mg serving daily and monitor your total calcium intake from all sources. You should check with your doctor before starting this supplement, especially if you take prescription medications for osteoporosis, thyroid conditions, or infections [NIH ODS]. If you experience constipation, nausea, or unusual tiredness, discontinue use and consult your healthcare provider [NIH ODS].
