Brand: Nature's Secret · Form: POWDER [E0162] On Market
Our assessment
The evidence shows that Nature's Secret 5-Day Fast & Cleanse Part 2 Fiber Cleanse contains calcium, a mineral with well-documented roles in the body. However, the available data does not support the use of this product for any specific health benefit related to "cleansing" or "fasting." You should be aware that the safety and efficacy of this specific formulation have not been established in clinical studies.
How it works
Calcium is best understood as a key structural and signaling mineral. It supports bone density and mineral deposition, which is critical for skeletal health [NIH ODS]. It also plays a role in neuromuscular relaxation, meaning it helps your muscles relax and your nerves send signals properly [NIH ODS]. The specific fiber blend in this product does not have data provided to support any unique mechanism beyond the general properties of calcium.
Safety profile
Data not available for this specific product's adverse events. However, the FDA has received a total of 592,059 adverse event reports for all dietary supplements [FDA data]. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Very 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
Our recommendation is to be cautious. Because no specific studies on this product were provided, we cannot endorse its use for "cleansing" or "fasting." If you are considering taking this supplement, you should first consult your healthcare provider, especially if you take any medications that interact with calcium. For general health, meeting your calcium needs through a balanced diet is typically safer and more effective than relying on an unstudied supplement formulation [NIH ODS].
