NOW Probiotic-10 25 Billion
Brand: NOW · Form: CAPSULE [E0159]
Our assessment
The evidence shows that calcium, when used as a supplement, plays a specific role in bone health, but the data does not support the use of NOW Probiotic-10 25 Billion for calcium delivery. This product is a probiotic, and calcium is not listed among its ingredients. For calcium-specific needs, you should look for a dedicated supplement, not a probiotic.
How it works
Calcium supports bone mineralization and neuromuscular relaxation, meaning it helps your body deposit minerals into bone tissue and supports proper nerve signaling and muscle function [NIH ODS]. However, since this product does not contain calcium, these mechanisms do not apply to NOW Probiotic-10 25 Billion.
Safety profile
Data not available for this specific product regarding calcium. The FDA has received 592,059 total adverse event reports across all supplement categories, but no specific side effect counts are provided for NOW Probiotic-10 25 Billion [FDA data]. If you were taking a calcium supplement, high intakes could cause constipation, nausea, and abnormal heart rhythms, but these risks do not apply here [NIH ODS].
Our recommendation
Our assessment: Do not take NOW Probiotic-10 25 Billion for calcium. It is a probiotic, and calcium is not an ingredient in this product. If you need a calcium supplement, choose a product that lists calcium on the label, and be aware that calcium can reduce absorption of medications like tetracycline antibiotics and levothyroxine [NIH ODS]. For general probiotic use, follow the label instructions.
