GNC Preventive Nutrition Advanced Complete Body Cleansing 14-Day Program Liquid Cleanse
Brand: GNC Preventive Nutrition · Form: SUPPLEMENT FORM, OTHER [E0172]
Our assessment
The evidence shows that this product contains calcium, a mineral with a specific role in the body. However, the use of a "14-day liquid cleanse" for general "body cleansing" is not supported by the data provided. Data on the product's other ingredients is not available, so we cannot assess the full formula. Our analysis focuses strictly on the calcium content.
How it works
Think of calcium as a structural building block for your bones and a signal messenger for your nerves and muscles. It supports bone mineralization and density, and it is critical for proper muscle relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all products. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Side effects of high calcium levels in the blood and urine 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 also reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data on the specific "cleansing" benefit of this product is not available. Because the formula is unknown beyond the calcium content, and because high calcium intake carries documented risks, we cannot recommend this product for the purpose of body cleansing. If you are considering a calcium supplement, discuss your specific needs with your healthcare provider, as they can help you determine an appropriate dose and check for medication interactions [NIH ODS].
