Why do probiotic pills sometimes contain less CFU than yogurt?

377 viewsBiologyOther

My doctor recommended I take a probiotic after a round of antibiotics that is 100 million CFU whereas many yogurts advertise billions of CFU. Why is that the case?

You eat a cup of yoghurt and a teaspoon of supplement. The supplements are not 100% bacteria they are a growing medium that has reached saturation, just like yoghurt. The only difference is they are dried and put in capsules or pressed into pills.

Like with all things that experience exponential growth until they hit a limit. (yeast, viruses, bacteria, mold, dandelions in your yard) The initial amount doesn’t really matter as long as it’s large enough for a population to survive.
