Our assessment
The evidence shows that Nature's Way Fiber Fusion Daily is a dietary supplement, but the specific ingredient data provided is for calcium. Our assessment is that you should be cautious if this product contains calcium, as the data on calcium is mixed and requires careful consideration. We do not have specific data for the fiber blend itself in this product, so we must focus on the calcium component as provided [NIH ODS].
How it works
If this product contains calcium, it works by supporting bone mineralization and neuromuscular relaxation. Think of it as a structural building block for your bones and a regulator for your nerves and muscles [NIH ODS].
Safety profile
Safety data for this specific product is not available, but the FDA has received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High levels of calcium 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 the product label to see if it contains calcium and how much. If it does, be aware that calcium can reduce the absorption of medications like bisphosphonates, tetracycline and fluoroquinolone antibiotics, levothyroxine, and phenytoin. Do not exceed the recommended dosage and consult your doctor before use, especially if you have a history of kidney problems or heart disease [NIH ODS].
