Our assessment
The evidence shows that GNC Preventive Nutrition Advanced Complete Body Cleansing 14-Day Program Cleansing Fiber Sachet contains calcium as a key ingredient. Our assessment is that while calcium supports bone health, the "cleansing" claim is not supported by the specific data provided. Data not available for the product's overall effectiveness.
How it works
Calcium in this product works as a master regulator for bone mineralization, helping to support bone density and mineral deposition. It also plays a role in neuromuscular relaxation, supporting muscle relaxation and nerve signaling [NIH ODS]. Think of calcium as the structural building block your body relies on for strong bones and proper nerve function.
Safety profile
FDA received 592,059 total adverse event reports across all supplements. 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
We recommend you consult your healthcare provider before starting this 14-day program, especially if you take any medications that interact with calcium. Be aware that the "cleansing" aspect is not backed by the data provided, and focus instead on whether you need additional calcium in your diet.
