GNC Preventive Nutrition Advanced Complete Body Cleansing 14-Day Program Cleansing Fiber Sachet
Brand: GNC Preventive Nutrition · Form: SUPPLEMENT FORM, OTHER [E0172]
Our assessment
The evidence shows that this product contains a significant amount of calcium, a mineral essential for bone health. However, the specific cleansing and fiber claims of this 14-day program are not supported by the data provided. Our assessment is that while calcium supports your body's basic functions, the "body cleansing" purpose of this product lacks specific scientific backing in the available data.
How it works
Calcium works as a master regulator for your bones and muscles. It supports bone mineralization and mineral deposition, and it helps your muscles relax and your nerves signal properly [NIH ODS]. Think of it as the key building block for your skeleton and a calming signal for your neuromuscular system.
Safety profile
Data not available for this specific product's adverse events. The FDA has received 592,059 total adverse event reports across all dietary supplements, but data for this specific GNC product is not available [FDA data]. For calcium specifically, high intakes from supplements might increase the risk of heart disease and prostate cancer. Very high levels in the blood can cause constipation, nausea, extreme tiredness, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
We recommend you do not use this product for "body cleansing" purposes, as the data does not support that claim. If you are considering it for calcium, be aware that this is a short-term 14-day program, not a long-term calcium supplement. You should get your calcium needs from food or a standard daily supplement, and always take calcium supplements at least two hours apart from any prescription medications you may be taking [NIH ODS].
