Renew Life FiberSmart
Brand: Renew Life · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Renew Life FiberSmart is a fiber supplement, but its primary active ingredient is calcium based on the data provided. Our assessment: calcium is a well-supported mineral for bone health, but the data does not allow us to evaluate the specific fiber blend or its effectiveness as a standalone product. You should be aware that the product's benefits are tied to calcium, not necessarily the fiber content [NIH ODS].
How it works
Think of calcium as a structural building block for your bones. It supports bone mineralization and density, and it also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
Data not available for Renew Life FiberSmart specifically. However, FDA received 592,059 total adverse event reports across all supplements. For calcium, high intakes might increase the risk of heart disease and prostate cancer. 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] [FDA data].
Our recommendation
Our recommendation: Do not use this product without first consulting your healthcare provider. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Given the lack of specific fiber data and the potential risks of high calcium intake, you should prioritize getting your calcium from food sources and discuss any supplement use with your doctor.
