Our assessment
The evidence shows that this product’s main active ingredient, Calcium, is essential for bone health, but the specific GNC Preventive Nutrition Complete Body Cleansing 7-Day Program Fiber and Prebiotic Blend Packet has very limited data on its overall effectiveness. Our assessment is that while the individual ingredient has established benefits, you should be cautious about the claims of a "cleanse" and focus on the known effects of calcium [NIH ODS].
How it works
Think of calcium as a structural builder for your bones. It supports bone density and mineral deposition, which is critical for maintaining strong bones as you age. It also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly after exercise or daily activity [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels in your 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] [FDA data].
Our recommendation
We recommend you do not use this product without first consulting your doctor. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data on the specific "cleanse" benefits of this blend is not available. Prioritize getting your calcium from food sources and speak with your healthcare provider before starting any new supplement regimen.
