Renew Life Fiber Smart
Brand: Renew Life · Form: POWDER [E0162]
Our assessment
The evidence shows that Renew Life Fiber Smart is a dietary supplement that provides calcium as a key ingredient. Our assessment is that while calcium is essential for health, you need to be aware of specific safety considerations and potential medication interactions before adding this product to your routine [NIH ODS].
How it works
Calcium plays a critical role in your body. It supports bone mineralization, helping to build and maintain strong bone density. It also aids in neuromuscular relaxation, which is important for proper muscle function and nerve signaling [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports for this product category. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. High levels of calcium 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
We recommend you check for potential medication interactions before use. Calcium can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. You should take this supplement at least two hours apart from those medications. Data on the specific fiber blend in this product is not available, so consult your healthcare provider to determine if this supplement is appropriate for your individual health needs.
