Natural Factors Low FODMAP Reliefiber Unflavored
Brand: Natural Factors · Form: POWDER [E0162] On Market
Our assessment
The evidence shows that the primary ingredient in Natural Factors Low FODMAP Reliefiber Unflavored is calcium. Based on the data, this product may support bone health, but it is not a fiber supplement as the name suggests. You should be aware of the potential risks and drug interactions associated with calcium supplementation.
How it works
Calcium plays a critical role in bone mineralization, helping to support bone density and mineral deposition. It also supports neuromuscular relaxation and normal nerve signaling [NIH ODS]. Think of it as a foundational mineral for your skeleton and muscle function.
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Very 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend you check with your doctor before taking this product, especially if you take any prescription medications. Do not exceed the recommended dose on the label. If you are looking for a true low FODMAP fiber supplement for digestive health, this product may not be appropriate, as the data shows its primary ingredient is calcium, not fiber.
