GNC Probiotic Solutions Probiotic Solutions Women's 30 Billion CFUs

Our assessment

The evidence shows that this product contains calcium, a mineral essential for bone health. However, the specific probiotic strains and their colony-forming units (CFUs) are the primary ingredients listed on the label, and we do not have specific data on those strains. Our assessment is based on the calcium content, which is a common addition to women's probiotic formulas. The data indicates that calcium supports bone mineralization and neuromuscular function [NIH ODS].

How it works

Think of calcium as a structural building block for your bones and a messenger for your muscles and nerves. It works by supporting bone density through mineral deposition and helps your muscles relax and your nerves signal properly [NIH ODS].

Safety profile

The FDA has received a total of 592,059 adverse event reports across all supplement categories, but specific report counts for this product are not available. For calcium, the data warns that high intakes might increase the risk of heart disease and prostate cancer. 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].

Our recommendation

If you are using this product for its probiotic benefits, be mindful of the calcium content, especially if you take other calcium supplements. Calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available on specific probiotic strain benefits. Speak with your healthcare provider to ensure this product fits your individual health needs and does not interfere with any medications you take.
