GNC Preventive Nutrition Advanced Complete Body Cleansing 14-Day Program Cleansing Fiber Sachet
Brand: GNC Preventive Nutrition · Form: POWDER [E0162]
Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health, but the specific formulation of GNC Preventive Nutrition Advanced Complete Body Cleansing 14-Day Program Cleansing Fiber Sachet has limited data to support its marketed cleansing claims. Our assessment is that while calcium supports bone mineralization and neuromuscular relaxation [NIH ODS], the "cleansing" benefits are not substantiated by the data provided.
How it works
Calcium works as a master regulator in your body, helping to support bone density through mineral deposition and aiding muscle relaxation and nerve signaling [NIH ODS]. However, the specific mechanism for a 14-day "cleansing" program is not described in the available data, so you should view this product primarily as a calcium and fiber supplement rather than a detoxifying agent.
Safety profile
FDA received 592,059 total adverse event reports across all supplements, though specific report counts for this exact product are not provided. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. 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]. Calcium can also reduce absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by evaluating your total calcium intake from food and other supplements to avoid exceeding safe levels. Be aware that this product's "cleansing" claim is not supported by the provided data. If you take any of the listed medications, separate your supplement intake by at least 2 hours to avoid absorption issues [NIH ODS]. Choose a product with clearer evidence for your specific health goals.
