NOW Respiratory Care Probiotic
Brand: NOW · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that NOW Respiratory Care Probiotic contains calcium, which plays a key role in bone mineralization and neuromuscular function [NIH ODS]. However, the data does not provide specific information on the probiotic strains or their respiratory benefits for this product. Our assessment is that while calcium is a well-studied mineral for bone health, the specific claims about respiratory support from this probiotic are not supported by the data provided.
How it works
Think of calcium as a structural building block and a nerve signal messenger. It supports bone density and mineral deposition, and it helps your muscles relax and your nerves send signals properly [NIH ODS]. The data does not describe how the probiotic component of this product works.
Safety profile
FDA received a total of 592,059 adverse event reports across all products in their database [FDA data]. For calcium specifically, high intakes may increase the risk of heart disease, prostate cancer, and abnormal heart rhythms. Side effects from high calcium levels include poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, frequent urination, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend you consult with your healthcare provider before starting this product, as the specific respiratory benefits are not detailed in the available data. If you are taking any medications, especially antibiotics or thyroid medication, be aware of potential interactions with calcium [NIH ODS]. Data not available on the specific probiotic strains or their effects for respiratory health.
