Best probiotic supplement? Is align good?

Align is good. There are multiple probiotics in market but align is one of the few probiotic that has been tried in medical trial on ibs patients with positive response especially patients with diarrhea, gas and bloating.
Too weak! Better than nothing, but:

The qualities of a good probiotic are the number of good bacteria per capsule and the number of species of good bacteria! 10 billion with ten strains is what to try for! Would be hard to overdose. Some have 50 billion good bacteria, but you pay for it! Healthy for the microbiome-the world inside you.
