NOW Probiotic-10 50 Billion
Brand: NOW · Form: CAPSULE [E0159]
Our assessment
The evidence shows that NOW Probiotic-10 50 Billion contains Calcium, which is a mineral essential for bone health and nerve function [NIH ODS]. However, based on the data provided, we cannot assess the specific benefits of the probiotic strains in this product, as no data on those ingredients was supplied. Our assessment is that while calcium has a well-established role in bone mineralization and neuromuscular relaxation [NIH ODS], the overall effectiveness of this specific probiotic formulation cannot be determined from the available information.
How it works
Calcium works as a master regulator for your body. It supports bone density by aiding in mineral deposition, and it helps your muscles relax and nerves signal properly [NIH ODS]. For a probiotic product, you would typically expect live bacteria to support gut health, but data on those specific bacteria is not available for this analysis.
Safety profile
FDA received 592,059 total adverse event reports for all products in the database, but the data does not break down how many are specific to this supplement [FDA data]. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from very high calcium levels include poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend you speak with your healthcare provider before starting this supplement, especially if you take any medications that interact with calcium [NIH ODS]. Data not available on the specific probiotic strains or their benefits, so we cannot recommend this product for digestive or immune support based on the provided information. If you are taking this for calcium, ensure you are not exceeding the recommended intake and monitor for side effects like constipation or nausea [NIH ODS].
