Nature's Way Fortify Women's Probiotic 30 Billion

Our assessment

The evidence shows that this product contains calcium, a mineral essential for bone health. Our assessment is that while calcium is a key nutrient, the specific benefits of this probiotic product for women are not directly supported by the data provided. The data we have focuses on the calcium ingredient, not the probiotic blend. You should understand the role of calcium and its potential risks before using this supplement.

How it works

Think of calcium as a structural builder for your bones. It supports bone density and mineral deposition through a process called bone mineralization [NIH ODS]. It also plays a critical role in your nervous system, helping with neuromuscular relaxation and nerve signaling [NIH ODS]. These functions are vital for maintaining strong bones and proper muscle function as you age.

Safety profile

The FDA has received a total of 592,059 adverse event reports across all supplement categories, though the specific number for this exact product is not available. 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

We recommend you consult with your healthcare provider before starting this supplement, especially if you take any medications or have a history of kidney stones or heart disease. Do not exceed the recommended dose on the label. If you experience constipation, nausea, or any unusual symptoms, stop taking the product and speak with your pharmacist or doctor. Data not available on the specific probiotic strains or their benefits in this product.
