If you read enough supplement labels, "12 billion CFU" starts to sound like a number from a marketing spreadsheet. It is not. It is a count, not a claim, and the count is the point.
CFU stands for colony-forming units. It is a way of saying how many living, dividing bacterial cells are in the scoop. Probiotics only work if they are alive when you take them. The whole reason we print 12 billion on the front of every jar is that we measured the count at the moment the jar was sealed, and we guarantee it is still that high through the printed expiration date.
That last part matters. A label that says "12B CFU at time of manufacture" is not the same as "12B CFU at time of consumption". The first one is a starting count. The second one is what you actually take. Ours is the second one. We test the count quarterly to make sure it holds.
The five strains are listed by name, in order of dose, on the supplement panel. We do not hide anything inside a "proprietary blend". If a strain is on the jar, the dose is on the jar.
