Renew Life Fiber Smart

Our assessment

The evidence shows that Renew Life Fiber Smart is a fiber supplement intended to support digestive regularity. However, based on the data provided, the primary ingredient with detailed health information is calcium, not a specific fiber component. Our assessment is that while fiber supplements can be beneficial, the available data on this product's active ingredients is limited. We must rely on the calcium data provided, which shows calcium supports bone mineralization and neuromuscular relaxation [NIH ODS].

How it works

Think of calcium as a critical mineral for your body. It supports bone density and mineral deposition, helping keep your skeleton strong. Additionally, it plays a role in neuromuscular relaxation, meaning it helps your muscles relax and your nerves signal properly [NIH ODS]. If this product contains a fiber source, fiber generally works by adding bulk to stool and promoting regular bowel movements, but specific data on the fiber ingredient in this product is not available.

Safety profile

FDA received a total of 592,059 adverse event reports across all supplement categories, but specific report counts for this product are not available. Regarding the calcium component, high intakes might increase the risk of heart disease and prostate cancer. Very high levels of calcium can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Data not available on specific dosing for Renew Life Fiber Smart. If you are considering this product, consult with your healthcare provider first, especially if you take any medications that interact with calcium. For general health, ensure you are meeting your calcium needs through diet, and be aware of the potential risks of high calcium intake [NIH ODS]. Always follow the label instructions and do not exceed recommended amounts.
