Creative Bioscience Pure Fiber Unflavored

Our assessment

The evidence shows that Creative Bioscience Pure Fiber Unflavored contains calcium as its primary active ingredient. Our assessment is that this product can be a useful way to support your daily calcium intake, but you need to be careful with dosing and timing relative to other medications. Data on total adverse events for all products in this category includes 592,059 reports [FDA data].

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 key role in neuromuscular relaxation and nerve signaling [NIH ODS]. This means it helps your muscles relax properly and your nerves communicate effectively.

Safety profile

You should be aware that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels of calcium 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Start by checking your total daily calcium intake from food and other supplements to avoid exceeding safe levels. If you take any of the listed medications, separate your calcium dose by at least two hours. Data not available for specific side effect report counts for this product alone [FDA data].
