What CFU is the best?

[webheart]

You are asking someone who posts every article from medical xpress which colony forming unit is best? How would he know? Wylhy would it matter? The bacteria in yoghurt can’t even survive in a human digestive system. There are hundreds of probiotics being studied and not a single one of them can be demonstrated to have any discernible effect on human health.

CFU means colony forming units, not a measure of eficacy.
Yogurt always has the two basic bacteria, Streptococcus thermophilus and Lactobacillus bulgaricus, the rest are an adjunct, not either good or bad. You decide, but most commercially available yogurt has a list of other bacteria, as well as pectin, only used to prevent separation during transport. Make your own yogurt, it is very easy.
