Swanson Probiotic+ Prebiotic Fiber
Brand: Swanson · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Swanson Probiotic+ Prebiotic Fiber is a combination product, but our data only covers the calcium component. For calcium, the data confirms it is essential for bone mineralization and neuromuscular relaxation [NIH ODS]. However, you should be aware that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Data for the probiotic and prebiotic components are not available in the provided data.
How it works
Think of calcium as a structural builder and signal messenger — it supports bone density and mineral deposition, while also helping your muscles relax and your nerves send signals properly [NIH ODS]. Without adequate calcium, your body may leach it from your bones to maintain these critical functions.
Safety profile
FDA received a total of 592,059 adverse event reports across all products, but specific reports for this supplement are not available. For calcium specifically, high levels in the 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by checking if you already get enough calcium from food. If you take this supplement, take it separately from any medications listed in the interactions. Monitor for constipation or nausea. Data for the probiotic and prebiotic ingredients in this product are not available, so we cannot assess their specific benefits or risks [NIH ODS].
