If you want to take a supplement instead, keep these tips in mind
If you would rather take probiotic supplements than ingest them naturally in your foods, there are a few things you should look for when choosing a supplement:
- Number of live organisms: Our gut bacteria population is somewhere in the trillions, so anything less than one billion CFUs (colony-forming units) is just a drop in the bucket and won’t make much difference to overall gut health. Look for concentrations of several billion or better.
- Organism survival factor: Active organisms typically die at some point. Manufacturers should factor in survival rate by displaying the expected amount of living cultures upon expiration. Many do not, however, as it is not a regulated supplement.
