The Vitamin Shoppe Fiber Blend
Brand: The Vitamin Shoppe · Form: CAPSULE [E0159]
Our assessment
The evidence shows that The Vitamin Shoppe Fiber Blend is primarily a source of dietary fiber, but the data provided only covers one ingredient: Calcium. Based on the label, this product contains calcium, and our assessment of this ingredient is that it supports bone health, but you need to be aware of significant safety considerations [NIH ODS].
How it works
Calcium is a master regulator for your body. It works through two primary mechanisms: bone mineralization, where it supports bone density and mineral deposition, and neuromuscular relaxation, where it supports muscle relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements, though a specific count for this product is not available. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Proceed with caution. If you take this fiber blend, be aware of your total calcium intake from all sources to avoid exceeding safe levels. If you take any of the listed medications, take this product at least two hours apart from them to avoid absorption issues [NIH ODS]. Data not available for fiber-specific benefits or side effects from this blend.
