Brand: Natural Factors · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that this probiotic supplement is formulated for women, but the data provided does not include specific clinical studies on this exact product. The key ingredient with available data is calcium, which supports bone health [NIH ODS]. However, without a list of specific probiotic strains and their colony-forming units (CFUs) from the label, we cannot assess the specific benefits for your digestive or immune health. Our assessment is that you should verify the full label details before purchasing, as the data here is incomplete.
How it works
Calcium acts as a master regulator for your body's structural health. It supports bone mineralization, helping to deposit minerals into your skeleton for density and strength. It also plays a role in neuromuscular relaxation, allowing your muscles to relax and nerves to signal properly after contraction [NIH ODS]. The probiotic component, if present, would work by introducing live bacteria to support your gut microbiome, but specific mechanisms are not available from the provided data.
Safety profile
The FDA has received 592,059 total adverse event reports for all dietary supplements, but specific reports for this product are not available [FDA data]. For the ingredient calcium, high intakes are a concern: they might increase the risk of heart disease and prostate cancer. High levels 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].
Our recommendation
Data not available for a complete recommendation. You should check the product label for specific probiotic strains and CFU counts. If you are taking calcium from this product, be aware 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 this supplement, especially if you take any of those medications.
