Renew Life Triple Fiber
Brand: Renew Life · Form: CAPSULE [E0159]
Our assessment
Our assessment: The evidence shows that the primary active ingredient in Renew Life Triple Fiber is calcium, which plays a well-established role in bone health and nerve function [NIH ODS]. We can confidently say that this supplement may support your bone density and neuromuscular relaxation, but you should be aware of the significant safety considerations and potential medication interactions [NIH ODS].
How it works
Think of calcium as a building block for your skeleton. It supports bone mineralization and helps maintain strong, dense bones as you age [NIH ODS]. Additionally, calcium aids in neuromuscular relaxation, meaning it helps your muscles relax and your nerves signal properly after contraction [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports for this product category [FDA data]. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Very high levels in your 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].
Our recommendation
Our recommendation: If you take this product, be mindful that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. You should take this supplement at a different time than those medications. Data on the specific fiber blend in this product is not available, so consult your healthcare provider before starting this supplement, especially if you have a history of kidney problems or heart disease [NIH ODS].
