Swanson Probiotics Prune Regularity Complex with Probiotics & FOS

Our assessment

The evidence shows that Swanson Probiotics Prune Regularity Complex is a supplement designed to support digestive regularity, but the specific data for this product is limited. The primary active ingredient, calcium, is well-documented for its role in bone health and nerve function [NIH ODS]. However, you should be aware that the FDA has received a total of 592,059 adverse event reports for all supplements, which underscores the importance of cautious use [FDA data].

How it works

Think of calcium as a key player in your body’s signaling system. It supports bone mineralization, helping to maintain strong bones, and also aids in neuromuscular relaxation, which is essential for proper muscle and nerve function [NIH ODS]. While the product name suggests a focus on regularity, the data provided does not specify how the probiotic or FOS components work.

Safety profile

Data not available for the specific side effects of this product. However, based on the calcium content, high intakes may increase the risk of heart disease and prostate cancer. High levels of calcium in the blood can cause poor muscle tone, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. The FDA has received 592,059 total adverse event reports for supplements, but specific report counts for this product are not available [FDA data].

Our recommendation

Our recommendation: Start with a standard dose as directed on the label. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin, so take this supplement at a different time than those medications [NIH ODS]. If you experience any side effects like nausea or constipation, discontinue use and consult your healthcare provider.
