Our assessment
The evidence shows that Regular Girl Prebiotic Fiber & Probiotic contains calcium as a key ingredient. Based on the data provided, calcium supports bone density and neuromuscular relaxation [NIH ODS]. However, the safety profile requires close attention to dosage and potential adverse effects.
How it works
Think of calcium as a building block for your bones and a signal regulator for your nerves and muscles. It works by supporting bone mineralization and mineral deposition, while also helping your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplement products. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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 several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by checking your total calcium intake from all sources, including food and other supplements. The data does not specify a recommended daily amount for this product, so consult with your healthcare provider to ensure you are not exceeding safe levels. Be especially cautious if you take any of the medications listed above, as calcium can interfere with their absorption [NIH ODS].
