A quick guide for choosing probiotics
This guide highlights key points to consider when choosing quality probiotics.
4 tips to keep in mind
1.
A health benefit demonstrated in a scientific study applies only to the specific probiotic strain studied – not to all probiotics.
2.
A probiotic containing multiple strains is not necessarily more effective than one containing a single strain. Health benefits should be demonstrated for the specific probiotic product in scientific studies.1
3.
The benefits of a probiotic strain should be evaluated in the population it is intended for. Results from studies in adults cannot automatically be assumed to apply to newborns.2
4.
Study results apply to the specific health outcome investigated. A probiotic shown to support immune health will not necessarily provide benefits for gut or oral health.
Does the quantity of probiotic bacteria matter?
Probiotic products contain billions of live bacteria capable of forming colonies. The number of probiotic bacteria in a product is expressed as Colony Forming Units (CFU). However, a higher CFU count does not necessarily mean a better probiotic.3 The amount needed depends on the specific strain, the health area being targeted, and the clinical evidence supporting its use.4
The importance of end of shelf life
To provide their intended benefit, probiotics must be alive when consumed. Because probiotic numbers naturally decline over time, it is important to check the CFU level stated at the end of shelf life rather than at the time of manufacture. Ideally, the end-of-shelf-life CFU count should be within the same range as that used in the scientific studies demonstrating the strain’s health benefit.1 Apart from yogurts, most probiotic products do not require refrigeration and can be stored at room temperature.3
