Query: If these helped, I didn't notice it.

I honestly don't think there's enough good bacteria in the pill. I bought them, took them, noticed no difference and wondered what went wrong. Then I did research and discovered that I was supposed to look for a probiotic supplement with at least 15 billion cultures per serving(this product has 1 billion), and at least 10 different strains(I think this product has 2). The only nice thing about these is that they are super tiny and easy to swallow. The problem is you need to tak every pill in the box all at once to notice a difference. I will look elsewhere next time.
