GNC Preventive Nutrition Complete Body Cleansing 7-Day Program Fiber And Prebiotic Blend Packet
Brand: GNC Preventive Nutrition · Form: POWDER [E0162]
Our assessment
The evidence shows that this product contains a fiber and prebiotic blend, but specific clinical studies on this exact formula are data not available. The primary ingredient with supporting data is calcium, which is included in the blend. Our assessment is that this 7-day program is likely safe for most people, but you should be aware of calcium's potential risks and interactions.
How it works
Think of the calcium in this blend as a mineral supporter — it works through bone mineralization to support bone density and mineral deposition, and it also supports neuromuscular relaxation and nerve signaling [NIH ODS]. The fiber and prebiotic components are intended to support digestive cleansing, though specific mechanism data for this proprietary blend is not available.
Safety profile
FDA received 592,059 total adverse event reports across all supplements, but specific report counts for this product are data not available. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from high calcium levels include 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 reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by checking your current calcium intake from food and other supplements. Do not exceed the tolerable upper intake level without medical supervision. If you take any of the listed medications, take them at least 2 hours apart from this product [NIH ODS]. For the best results, use this 7-day program only as directed on the label and stop use if you experience constipation or nausea. Data not available for long-term use beyond 7 days.
