GNC Preventive Nutrition Complete Body Cleansing Program Fiber and Prebiotic Blend
Brand: GNC Preventive Nutrition · Form: SUPPLEMENT FORM, OTHER [E0172]
Our assessment
The evidence shows that this product’s key active ingredient, calcium, is essential for bone health, but you should be aware of important safety considerations. The data specifically addresses calcium, not the full fiber and prebiotic blend in this product. For that reason, our review focuses on the calcium component as provided in the data.
How it works
Calcium acts as a master regulator for your body. It supports bone density and mineral deposition through a process called bone mineralization, and it also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
Data not available for the specific product formula. However, for calcium itself, 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]. The FDA has received a total of 592,059 adverse event reports across all supplements, though a specific count for this product is not available [FDA data].
Our recommendation
Because the data provided does not include a specific dosage or full ingredient list for this product, we cannot offer a precise recommendation for its use. If you are considering a calcium supplement, be aware that it can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Consult your healthcare provider before starting any new supplement regimen, especially if you take prescription medications.
