This is only one of the criteria. CFUs are the quantification of the number of bacteria present at the time of capsule manufacture.
Other important criteria are:
- The number of different strains present in the capsule, knowing that it is difficult to assume the effectiveness of a particular strain in a particular individual. The mix increases the chances of effectiveness
- The most important thing is the packaging in gastro-resistant capsules which is the best way to protect the ferments from stomach acidity which destroys them almost completely. Conventional powders, tablets or capsules do not offer this protection.
